T-6A INSTRUMENT NAVIGATION
The "time hack" will occur at 1335Z. A countdown to the hack is usually
commenced prior to conducting the time hack.
Student: "On my hack, the time will be 1335Z. 3-2-1 Hack... 1-2-3"
For the minutes and seconds required for turn point procedures, we normally use the elapsed
timer (ET) function of the aircraft clock.
Student: "On my hack, we will start the elapsed timer. 3-2-1 Hack 1-2-3"
The ET function of the aircraft's clock displays minutes and
seconds until reaching 59 minutes and 59 seconds, after that, it
displays hours and minutes. If the enroute portion of your flight
will exceed 59 minutes, you will need to re-hack the clock. This
should be done on any leg where a GS can be accomplished in
order to establish an ETA to your next point. This step shall be
accomplished prior to the end of the hour.
