Dear Mr. Humphrey,

This letter is in response to your letter dated January 21, 2011 containing comments of the staff of the Division of Corporation Finance on the Form 10-K and the Definitive Proxy Statement on Schedule 14A of Aerosonic Corporation (the “Company”) described above.

Pursuant to my telephone call on January 28 with Ms. Kristin Shifflett of your office, the Company requires additional time to respond fully to the comments and has therefore requested an extension of time to respond. I am confirming that, in accordance with my discussion with Ms. Shifflett, the Company anticipates responding to the comments contained in the January 21 letter on or before February 18, 2011.

If you have any questions, please call me at (727) 461-3000.

Sincerely,

/s/ Kevin J. Purcell
