T-6A INSTRUMENT NAVIGATION
3. Frequencies are listed at the top of IAP charts, you will see listed the most commonly used
frequencies and the name of the controlling ATC facility. So if you missed the frequency when
directed to contact Tower, look at the top of the approach plate.
4. Profile View. Review the profile view for altitudes and descent rates. Observe the altitude
restrictions and know where they apply. Minimum, maximum, mandatory, and recommended
altitudes precede the fix or facility to which they apply. If this is not the case, an arrow will
indicate exactly where the altitude applies. In this section, you will also find the published
missed approach procedures.
5. Review the Minima. The aircrew needs to know how low to descend and the student
should be able to determine if you have the weather for the type of approach you are planning to
fly. To find the above information, you need to know what category of aircraft you are flying.
Remember, the T-6A is a category B aircraft. If you are flying a VOR or LOC approach, also
note the time from the FAF to the MAP. Remember, the timing is based on GS, not IAS. In
intermediates, you will be required to calculate your actual GS using the known winds and then
interpolate to get the actual timing from the FAF to the MAP.
6. Aerodrome sketch to check the field elevation, which is the highest point on the usable
landing area. Additionally, note the direction and distance of the runway from the FAF. Also,
check the type of lighting expected in marginal visibility.
