FYI... and directly from the FAA.......
In order to log and use instrument training time in an FTD and/or ATD the device must have a letter from AFS-800, issued within the last year, approving its use. This letter must also state what maneuvers and regulation are approved for credit in the FTD/ATD. It will also have an expiration date on it.
This letter must be posted near the FTD/ATD and a copy must be given to the student.
Also, per the regulations the student must use a view limiting device (foggles, hood) and the CFII must be present.
I know FTDs and ATDs are good training devices but if the requirements aren't met, we can't use the time acquired towards meeting the requirements for a certificate or rating (ie. Instrument rating). Alot of this information has changed within the last 12 months. If there are any questions, please contract the FSDO.
