Accounting Policies [Abstract]
Basis of Accounting [Text Block]	Note 1 – Business, Organization and Liquidity Business and Organization Tel-Instrument Electronics Corp. (“Tel,” “TIC” or the “Company”) has been in business since 1947. The Company is a leading designer and manufacturer of avionics test and measurement instruments for the global, commercial air transport, general aviation, and government/military defense markets. Tel provides instruments to test, measure, calibrate, and repair a wide range of airborne navigation and communication equipment. The Company sells its equipment in both domestic and international markets. Tel continues to develop new products in anticipation of customers’ needs and to maintain its strong market position. Its development of multi-function testers has made it easier for customers to perform ramp tests with less operator training, fewer test sets, and lower product support costs. The Company has become a major manufacturer and supplier of Identification Friend or Foe (“IFF”) flight line test equipment over the last two decades. The Company is publicly traded and was quoted on the Over-the-Counter Market Place (“OTCQB”) under the symbol “TIKK.” Liquidity On December 31, 2021, the Company had positive working capital of $4,323,243 as compared to working capital of $3,159,731 on March 31, 2021. This included approximately $7.3 million of cash including the $2 million restricted cash supporting the appeal bond. The Company has recorded total damages of $6,045,924 including accrued interest, as a result of the jury verdict associated with the Aeroflex litigation. With a $3.3 million backlog on December 31, 2021, the Company expects that in fiscal year 2022, revenue and profitability will continue to improve. On March 27, 2020, former President Trump signed the Coronavirus Aid, Relief and Economic Security (the “CARES Act”), which, among other things, outlines the provisions of the Paycheck Protection Program (the “PPP”). The Company determined that it met the criteria to be eligible to obtain a loan under the PPP because, among other reasons, in light of the COVID-19 outbreak and the uncertainty of economic conditions related thereto, the loan was considered necessary to support the Company’s ongoing operations and retain all its employees. In addition, former President Trump signed into law the Paycheck Protection Program and Health Care Enhancement Act on April 24, 2020, which increased funding provided by the CARES Act. On May 4, 2020, the Company issued a promissory note (the “Note”) to Bank of America in the principal aggregate amount of $722,577 (the “PPP Loan”) pursuant to the Paycheck Protection Program (“PPP”) under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The amount was deposited in our bank on May 4, 2020. On June 5, 2020, the Paycheck Protection Program Flexibility Act was signed into law and extended the program until December 31, 2020. TIC qualified for full loan forgiveness on the initial tranche on December 18, 2020. On January 6, 2021, updated PPP guidance outlining program changes to enhance its effectiveness and accessibility was released on in accordance with the Economic Aid to Hard-Hit Small Businesses, Non-Profits, and Venues Act. This was available to companies that recorded greater than a 25% sales reduction in any quarter compared to the prior year. The Company qualified for this second round of funding and on March 15, 2021, the Company secured a Second Draw PPP loan in the amount of $722,577. On September 17, 2021, TIC qualified for full loan forgiveness of the second round of funding and was recognized as other income in the quarter ended September 30, 2021. On August 24, 2021, TIC, and the New Jersey Economic Development Authority (NJEDA) signed a small business emergency assistance grant agreement in the amount of $20,000. The funds related to the grant were received from the NJEDA on August 30, 2021, and were recognized as other income during the quarter ended September 30, 2021. Based on the foregoing, we believe that our expected cash flows from operations and current cash balances will be sufficient to operate in the normal course of business for next 12 months from the issuance date of these unaudited condensed consolidated financial statements, including any payments for settlement of the Aeroflex litigation. The Bank of America line of credit has been renewed for $690,000 and will expire on July 30, 2022. As of December 31, 2021, the line of credit draw remained at zero. Impact of the COVID-19 Coronavirus In December 2019, a novel strain of coronavirus, which causes the disease known as COVID-19, was reported to have surfaced in Wuhan, China. Since then, COVID-19 coronavirus has spread globally. In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic and the U.S. government imposed travel restrictions on travel between the United States, Europe, and certain other countries. The impact of this pandemic has been, and will likely continue to be, extensive in many aspects of society, which has resulted, and will likely continue to result, in significant disruptions to the global economy as well as businesses and capital markets around the world. On September 9, 2021, President Biden announced Executive Order 14042 (“Executive Order”) and related initiatives designed to lead the country out of the COVID-19 pandemic. The Executive Order includes policies that will require employees of contractors that do business with the federal government to be vaccinated. On September 24, 2021, The Safer Federal Workforce Task Force released COVID-19 vaccine guidance for Federal contractors and subcontractors. According to this guidance, covered employees must be fully vaccinated by December 8, 2021, or at the latest, by the first day of performance on a covered contract, absent the need for a disability or religious accommodation. In addition, covered contractors must follow the CDC’s mask and physical distance requirements for covered contractor employees and visitors. The Executive Order and the guidance apply to any prime contractor or subcontractor that is a party to a “contract or contract-like instrument” that includes a clause incorporating the requirements of the Executive Order. The new clause was applied on October 15, 2021, to only new federal contracts, solicitations, contract extensions and renewals. On December 7, 2021, the federal court in Georgia issued a preliminary injunction temporarily halting the enforcement of EO 14042 (Ensuring Adequate COVID Safety Protocols for Federal Contractors) for all covered contracts nation-wide. New guidance from OMB also followed suit giving federal agencies input on how to go about non-enforcement provisions until legal challenges have been resolved. The updated guidance will remain applicable despite any change to new or existing court decisions. The new guidance does not impact the Safer Federal Workforce Taskforce Guidance. The vast majority of TIC employees are fully vaccinated, and TIC is preparing for full compliance of the Executive Order should it apply.
