T-6A INSTRUMENT NAVIGATION
2. If you're IMC, this field will be in blue on the low chart but not all blue fields have a
published approach compatible with our aircraft. Green fields on the high chart may have
suitable DoD published low approaches and should be identified through preflight planning.
Every time you are handed off to a new controller, the new frequency shall be written down. As
a technique, it's a good idea to write down both the UHF and VHF frequency. Write each
frequency in an orderly fashion so the frequency in use is the last in the line. This method will
keep frequencies in sequence and allow you to identify the previous channel if communication
VHF is the primary radio at civilian airfields and it is therefore a good technique to use it in
civilian patterns. If you switch from using UHF to VHF or vice versa, always inform you
The following airspeed profiles will be adhered to on INAV flights and simulator events.
1. Climbs. 180 KIAS until 10,000 feet MSL. Above 10,000 feet MSL, climb airspeeds will
be determined at IP discretion within NATOPS limits.
2. Enroute. 240 TAS for low altitude structure (Victor routes) and 270 TAS for high altitude
structure (jet routes). All canned NPA routes are listed at 240 TAS.
Calculate the Indicated Airspeed (IAS) for the required TAS 500
feet prior to all enroute cruising altitudes. For this procedure, use
the indicated OAT (IOAT minus 15º C) to compute the IAS on
Cruise Descent. Last indicated airspeed.
Enroute Descent. 200 KIAS.
1. Radar Vectored. 200 KIAS, unless otherwise directed by ATC. This airspeed will be
maintained until the transition to BAC.
All other approaches from (IAF to BAC) airspeed will be 150 KIAS.
