normal visual glidepath. On a non-precision approach, a descent and speed reduction will be
On other types of straight-in approaches (TAC/VOR), the FAC may be as much as 30º off
runway heading. For example, the TAC 14 to North Whiting has a FAC of 124º, while actual
runway magnetic heading is 137. In these cases, it will be necessary to continue on the FAC
until you can make a turn to line up on centerline. To avoid needing large heading corrections at
low altitude, do not "angle in" toward the runway.
Some non-precision approaches have MDAs of 800/1 or higher. Typical approach speeds in the
T-6A (120 KIAS) could require descent rates in excess of 1600 fpm if you don't break out prior
to the MAP. In these cases, an aggressive power reduction, possibly idle power, may be
required. Remember, adjust nose attitude accordingly to maintain a safe speed. Try to dissipate
excess altitude and airspeed as soon as possible so you can arrest the resultant high sink rate
prior to the landing threshold.
Remember, just because the runway is in sight at the MAP does not mean a safe landing can be
made. Both of these conditions must be met before attempting a landing.
