T-6A INSTRUMENT NAVIGATION
The first time the aircraft crosses the station, commence the entry orbit.
Execute the 6 Ts:
TIME. Write it down (hr:min Z).
TURN. Turn to establish yourself on the entry heading.
TIME. Initial outbound timing is started when over/abeam the station/fix or wings
level, whichever occurs last. Subsequent outbound timing is started when outbound
and abeam the station. When holding overhead a station, the best indicator of abeam
is the TO-FROM indicator. With the correct inbound (holding) course set into the
CDI, you will have a TO indication when proceeding inbound to the station. At
station passage, the indication will change to a FROM indication. The indication will
once again change to a TO indication once you are past the abeam position during
your turn inbound. If the abeam position cannot be determined, start timing when the
turn outbound is completed.
TRANSITION. Direct the IP to transition to holding speed, if not previously
TWIST. Select the source for the CDI. Put the holding course in the CDI. This may
be done any time after the initial turn, but must be completed prior to the inbound
TALK. Give the voice report stating time and altitude established in holding, if
IAW the AIM, the time and altitude or flight level upon reaching a
holding fix or point to which cleared should be made to ATC or
FSS facilities without a specific ATC request. This report may be
omitted by pilots of aircraft involved in instrument training at
military terminal area facilities when radar service is being
After the completion of timing, turn to intercept the holding course inbound. To remain within
holding airspace, a turn in the proper direction must be made. The direction of turn will be
determined as follows:
Determine your present position. Do this by visualizing yourself on the tail of the bearing
pointer. Turn toward the holding radial. In Figure 4-14, aircraft A is on the 070° radial with the
