| CHAPTER FIVE
T-6A NAVIGATION
"Airspeed one-eighty-five" (Note 3)
3.
4.
"Climb to two thousand for the next leg"
"Point/Target is an East-West road bridge, East of Sheboygan. A limiting feature of a 450
5.
feet tower is located just past the point. VR 1021 crosses the point West to East." (Notes 4 and 5)
NOTES
1.
Be precise with time. If only 1 minute away, then say 1
minute prior.
2.
Headings are spoken in single digits and are wind-
compensated. Add / subtract the crab from the course as
appropriate.
3.
Airspeeds are wind-compensated. Add / subtract the
headwind/tailwind component to maintain 180 knots ground speed.
4.
A brief description along with any hazards. Your
description of the turnpoint will include 2-3 items from inside the
turnpoint circle that positively identify the point.
5.
After you have briefed the 2 minute prior call, keep your
eyes outside and clear for hazards and turnpoint identification.
There should be almost no reason to look at your chart!
To determine wind-compensated headings and airspeeds, refer to the adjustments you preflighted
and recorded on your chart (T-6A only). As you gain more experience, you will not record these
numbers on your chart and will have to determine them based on mission progress.
Mark-On-Top call
1.
"Turn left three-zero-five" (Notes 1, 2)
2.
"Time is twenty four plus fifty" (Note 3)
3.
"Set airspeed one eighty-five" (Note 4)
4.
"Clear left"
An accurate mark-on-top is critical to future course corrections, mission timing, and wind
analysis. Look to the sides of the aircraft to find points abeam the turnpoint and attempt to mark-
on-top as accurately as possible. Picking references to the side will allow you to initiate the turn
even if the turnpoint is not in sight (i.e. underneath the airplane).
