Accounting Policies [Abstract]

Consolidation, Policy [Policy Text Block]

Principles of Consolidation:

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and include the Company and its wholly-owned subsidiary. All significant inter-company accounts and transactions have been eliminated.

Revenue [Policy Text Block]

Revenue Recognition:

Under Financial Accounting Standards Board (“FASB”) Topic 606, Revenue from Contacts with Customers (“ASC 606”), the Company recognizes revenue when the customer obtains control of promised goods or services, in an amount that reflects the consideration which is expected to be received in exchange for those goods or services. The Company recognizes revenue following the five-step model prescribed under ASC 606: (i) identify contract(s) with a customer; (ii) identify the performance obligation(s) in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligation(s) in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods and services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

The Company accounts for revenue recognition in accordance with ASC 606.The core principle of Topic 606 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The ASC 606 defines a five-step process to achieve the core principle and, in doing so, it is possible more judgement and estimates may be required within the revenue recognition process than are currently in use.

The Company generates revenue from designing, manufacturing, and selling avionic tests and measurement solutions for the global commercial air transport, general aviation, and government/military aerospace and defense markets. The Company also offers calibration and repair services for a wide range of airborne navigation and communication equipment.

Nature of goods and services

The following is a description of the products and services from which the Company generates revenue, as well as the nature, timing of satisfaction of performance obligations, and significant payment terms for each.

Test Units/Sets

The Company develops, and manufactures unit sets to test navigation and communication equipment, such as ramp testers and bench testers for radios installed in aircraft. The Company recognizes revenue when the customer obtains control of the Company’s product based on the contractual shipping terms of the contract, usually at time of shipment. Revenue on products is presented gross because the Company is primarily responsible for fulfilling the promise to provide the product, is responsible to ensure that the product is produced in accordance with the related supply agreement and bears the risk of loss while the inventory is in-transit. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products to the customer.

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines stand-alone selling prices based on the price at which the performance obligation is sold separately. If the stand-alone selling price is not observable through past transactions, the Company estimates the standalone selling price considering available information such as market conditions and internally approved pricing guidelines related to the performance obligations.

When determining the transaction price of a contract, an adjustment is made if payment from the customer occurs either significantly before or significantly after performance, resulting in a significant financing component. Applying the practical expedient in paragraph 606-10-32-18, the Company does not assess whether a significant financing component exists if the period between when the Company performs its obligations under the contract and when the customer pays is one year or less. None of the Company’s contracts contained a significant financing component as of March 31, 2022.

Replacement Parts

The Company offers replacement parts for test equipment, ramp testers, and bench testers. Similar to the sale of test units, the control of the product transfers at a point of time and therefore, revenue is recognized at the point in time when the obligation to the customer has been fulfilled.

Extended Warranties

The extended warranties sold by the Company provide a level of assurance beyond the coverage for defects that existed at the time of a sale or against certain types of covered damage with coverage terms generally ranging from 5 to 7 years. Amounts received for warranties are recorded as deferred revenue and recognized as revenue ratably over the respective term of the agreements. As of March 31, 2022, approximately $386,907 is expected to be recognized from remaining performance obligations for extended warranties as compared to $408,219 on March 31, 2021. For the year ended March 31, 2022, the Company recognized revenue of $75,791 from amounts that were included in Deferred Revenue as compared to $86,588 for the year ended March 31, 2021.

The following table provides a summary of the changes in deferred revenues related to extended warranties for the year ended March 31, 2022:

Deferred revenues related to extended warranties on April 1, 2021	$	408,219
Additional extended warranties		54,479
Revenue recognized for the year ended March 31, 2022		(75,791	)
Deferred revenues related to extended warranties on March 31, 2022	$	386,907

Other Deferred Revenues

The Company sometimes receives payments in advance of shipment. These amounts are classified as other deferred revenues. For the period ended March 31, 2022, the Company has other deferred revenues of $21,999 and $74,920 for the prior year ended March 31, 2021.

Repair and Calibration Services

The Company offers repair and calibration services for units that are returned for annual calibrations and/or for repairs after the warranty period has expired. The Company repairs and calibrates a wide range of airborne navigation and communication equipment. Revenue is recognized at the time the repaired or calibrated unit is shipped back to the customer, as it is at this time that the work is completed.

Other

The majority of the Company’s revenues are from contracts with the U.S. government, airlines, aircraft manufacturers, such as Boeing and Lockheed Martin, domestic distributors, international distributors for sales to military and commercial customers, and other commercial customers. The contracts with the U.S. government typically are subject to the Federal Acquisition Regulation (“FAR”) which provides guidance on the types of costs that are allowable in establishing prices for goods and services provided under U.S. government contracts.

Payment terms and conditions vary by contract, although terms generally include a requirement of payment within a range from 30 to 60 days, or in certain cases, up-front deposits. In circumstances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined that the Company's contracts generally do not include a significant financing component. Payments received prior to the delivery of units or services performed are recorded as deferred revenues. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from sales. The Company applied the practical expedient to account for shipping and handling activities as fulfillment cost rather than as a separate performance obligation. Shipping and handling costs charged to customers are classified as sales, and the shipping and handling costs incurred are included in cost of sales. All sales are denominated in U.S. dollars. The Company excludes from revenues all taxes assessed by a governmental authority that are imposed on the sale of its products and collected from customers. The Company chose to apply the available practical expedient as commission eligible sales orders are fulfilled within less than one year and commissions are generally paid by the Company within 30 days of the related sales order fulfillment. Accordingly, management has determined that no change in accounting for costs to obtain a contract will be required for the Company to conform to ASC 606.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair Value of Financial Instruments:

Accounting Standards Codification subtopic 825-10, Financial Instruments ("ASC 825-10") requires disclosure of the fair value of certain financial instruments. The carrying value of cash, accounts payable and accrued liabilities as reflected in the balance sheets, approximate fair value because of the short-term maturity of these instruments. All other significant financial assets, financial liabilities and equity instruments of the Company are either recognized or disclosed in the financial statements together with other information relevant for making a reasonable assessment of future cash flows, interest rate risk and credit risk. Where practicable the fair values of financial assets and financial liabilities have been determined and disclosed; otherwise only available information pertinent to fair value has been disclosed. The Company follows Accounting Standards Codification subtopic 820-10, Fair Value Measurements and Disclosures ("ASC 820-10") and ASC 825-10, which permits entities to choose to measure many financial instruments and certain other items at fair value.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash: Cash primarily consists of deposits held at major banks.

Concentrations of Credit Risk:

Cash held in banks: The Company maintains cash balances at a financial institution that is insured by the Federal Deposit Insurance Corporation (“FDIC”) up to federally insured limits. At times balances may exceed FDIC insured limits. The Company has not experienced any losses in such accounts.

Receivable [Policy Text Block]

Accounts Receivable: The Company’s avionics customer base is primarily comprised of airlines, distributors, and the U.S. Government. As of March 31, 2022, the Company believes it has no significant credit risk related to its concentration within its accounts receivable.

Inventory, Policy [Policy Text Block]

Inventories:

Inventories are stated at the lower of cost or net realizable value. Cost is determined on a first-in, first-out basis. Inventories are written down if the estimated net realizable value is less than the recorded value. The Company reviews the carrying cost of inventories by product to determine the adequacy of reserves for obsolescence. In accounting for inventories, the Company must make estimates regarding the estimated realizable value of inventory. The estimate is based, in part, on the Company’s forecasts of future sales and age of inventory. If actual conditions are less favorable than those we have projected, we may need to increase our reserves for excess and obsolete inventories. Any increases in our reserves will adversely impact our results of operations. The establishment of a reserve for excess and obsolete inventory establishes a new cost basis in the inventory. Such reserves are not reduced until the product is sold. If we are able to sell such inventory any related reserves would be reversed in the period of sale. In accordance with industry practice, service parts inventory is included in current assets, although service parts are carried for established requirements during the serviceable lives of the products and, therefore, not all parts are expected to be sold within one year.

Property, Plant and Equipment, Policy [Policy Text Block]

Equipment and Leasehold Improvements:

Office and manufacturing equipment are stated at cost, net of accumulated depreciation. Depreciation and amortization are provided on a straight-line basis over periods ranging from 3 to 5 years. Leasehold improvements are amortized over the term of the lease or the useful life of the asset, whichever is shorter.

Maintenance, repairs, and renewals that do not materially add to the value of the equipment nor appreciably prolong its life are charged to expense as incurred. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in the Statement of Operations.

Research and Development Expense, Policy [Policy Text Block]

Engineering, Research and Development Costs:

Engineering, research, and development costs are expensed as incurred.

Revenue from Contract with Customer [Policy Text Block]

Deferred Revenues:

Amounts billed in advance of the period in which the service is rendered, or product delivered are recorded as deferred revenue. On March 31, 2022, and 2021, deferred revenues totaled $408,906 and $483,139, respectively. See above for additional information regarding our revenue recognition policies.

Earnings Per Share, Policy [Policy Text Block]

Net Income (Loss) per Common Share Attributable to Common Shareholders:

Net income (loss) per share attributable to common stockholders has been computed according to Accounting Standards Codification (“ASC 260”), Earnings per Share, which requires a dual presentation of basic and diluted income (loss) per share (“EPS”). Basic EPS attributable to common stockholders represents net income (loss) less preferred dividends divided by the weighted average number of common shares outstanding during a reporting period. Diluted EPS attributable to common stockholders reflects the potential dilution that could occur if securities, including preferred stock, warrants and options, were converted into common stock. The dilutive effect of outstanding warrants and options is reflected in earnings per share by use of the treasury stock method. The dilutive effect of preferred stock is reflected in earnings per share by use of the if-converted method. In applying the treasury stock method for stock-based compensation arrangements, the assumed proceeds are computed as the sum of the amount the employee must pay upon exercise and the amounts of average unrecognized compensation.

Income Tax, Policy [Policy Text Block]

Income Taxes

The Company accounts for income taxes using the asset and liability method described in FASB ASC 740, Income Taxes Deferred tax assets arise from a variety of sources, the most significant being a) tax losses that can be carried forward to be utilized against profits in future years; b) expenses recognized for financial reporting purposes but disallowed in the tax return until the associated cash flow occurs; and c) valuation changes of assets which need to be tax effected for book purposes but are deductible only when the valuation change is realized.

Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using enacted tax rates and laws that are expected to be in effect when such differences are expected to reverse. The measurement of deferred tax assets is reduced, if necessary, by a valuation allowance for any tax benefit which is not more likely than not to be realized. In assessing the need for a valuation allowance, future taxable income is estimated, considering the realization of tax loss carryforwards. Valuation allowances related to deferred tax assets can also be affected by changes to tax laws, changes to statutory tax rates and future taxable income levels. In the event it was determined that the Company would not be able to realize all or a portion of our deferred tax assets in the future, we would reduce such amounts through a charge to income in the period in which that determination is made. Conversely, if we were to determine that we would be able to realize our deferred tax assets in the future in excess of the net carrying amounts, we would decrease the recorded valuation allowance through an increase to income in the period in which that determination is made. In its evaluation of a valuation allowance the Company considers existing contracts and backlog, and the probability that options under these contract awards will be exercised as well as sales of existing products. The Company prepares profit projections based on the revenue and expenses forecast to determine that such revenues will produce sufficient taxable income to realize the deferred tax assets.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes - simplifying the accounting for income taxes (Topic 740), which is meant to simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740, Income Taxes. The amendment also improves consistent application and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This ASU was effective April 1, 2021, and adoption of this standard had no significant impact on our financial position and results of operations.

The Company accounts for uncertainties in income taxes under ASC 740-10-50 which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740-10 requires that the Company determine whether the benefits of its tax positions are more-likely-than-not of being sustained upon audit based on the technical merits of the tax position. The Company recognizes the impact of an uncertain income tax position taken on its income tax return at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. The implementation of ASC 740-10 had no impact on the Company’s results of operations or financial position.

Despite the Company’s belief that its tax return positions are consistent with applicable tax laws, one or more positions may be challenged by taxing authorities. Settlement of any challenge can result in no change, a complete disallowance, or some partial adjustment reached through negotiations or litigation. Interest and penalties related to income tax matters, if applicable, will be recognized as income tax expense.

During the years ended March 31, 2022, and 2021 the Company did not incur any expense related to interest or penalties for income tax matters, and no such amounts were accrued as of March 31, 2022, and 2021. The Company’s tax years remain open for examination by the tax authorities primarily beginning 2019 through present.

Share-Based Payment Arrangement [Policy Text Block]

Stock-based Compensation:

The Company accounts for stock-based compensation in accordance with FASB ASC 718 which requires the measurement of stock-based compensation based on the fair value of the award on the date of grant. The Company recognizes compensation cost on awards on a straight-line basis over the vesting period, typically four years. The Company estimates the fair value of each option granted using the Black-Scholes option-pricing model. Additional information and disclosure are provided in Note 16 below.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Long-Lived Assets:

The Company assesses the recoverability of the carrying value of its long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future, undiscounted cash flows expected to be generated by an asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. No impairment losses have been recognized for the years ended March 31, 2022, and 2021, respectively.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates:

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires that management make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates include income taxes, warranty claims, inventory, and accounts receivable valuations.

Trade and Other Accounts Receivable, Unbilled Receivables, Policy [Policy Text Block]

Accounts Receivable:

The Company performs ongoing credit evaluations of its customers and adjusts credit limits based on customer payment and current credit worthiness, as determined by review of their current credit information. The Company continuously monitors credit limits for and payments from its customers and maintains provision for estimated credit losses based on its historical experience and any specific customer issues that have been identified. While such credit losses have historically been within the Company’s expectation and the provision established, the Company cannot guarantee that this will continue.

Guarantees, Indemnifications and Warranties Policies [Policy Text Block]

Warranty Expenses:

Warranty reserves are based upon historical rates and specific items that are identifiable and can be estimated at time of sale. While warranty costs have historically been within the Company’s expectations and the provisions established, future warranty costs could be in excess of the Company’s warranty reserves. A significant increase in these costs could adversely affect the Company’s operating results for the period and the periods these additional costs materialize. Warranty reserves are adjusted from time to time when actual warranty claim experience differs from estimates. For the year ended March 31, 2022, warranty reserve costs were $38,236 as compared to $64,092 for the year ended March 31, 2021, and are included in Cost of Sales in the accompanying consolidated statement of operations. See Note 7 for warranty reserves.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

Risks and Uncertainties:

The Company’s operations are subject to a number of risks, including but not limited to changes in the general economy, demand for the Company’s products, the success of its customers, research and development results, reliance on the government and commercial markets, litigation, and the renewal of its line of credit. The Company has major contracts with the U.S. Government, which like all government contracts are subject to termination.

New Accounting Pronouncements, Policy [Policy Text Block]

New Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13 Financial Instruments -Credit Losses (Topic 326), Measurement of Credit Losses on Financial Statements. The amendment in this update replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses on instruments within its scope, including trade receivables. This update is intended to provide financial statement users with more decision-useful information about the expected credit losses. The effective date of new standard has been deferred to April 1, 2023. We do not expect the adoption of this standard to have a significant impact on our financial position and results of operations.

No other recently issued accounting pronouncements had or are expected to have a material impact on the Company’s consolidated financial statements.
