The Approach pattern approximates the procedures required to execute an Instrument
approach over a radio facility.
The maneuver is started in normal cruise on a cardinal heading in the following manner:
Roll into a right SRT (twoneedle widths) for 90º of heading change. Maintain
altitude and airspeed.
After completion of the turn, note the time and commence timing outbound for
Transition to 120 knot descent by reducing the power to 300 ftlbs torque,
while maintaining altitude. As the airspeed decelerates toward 120 knots,
lower the nose to approximately 2º nose down and descend for 1000 feet at
120 knots. Trim the aircraft for a 120 knot descent.
Twenty five feet prior to level off, transition to level flight by adding power to
approximately 450500 ftlbs, and raising the nose to the slow cruise attitude
(approximately 1½º nose up), and retrim.
At the end of three minutes timing outbound, commence a left StandardRate Turn
for 210º of heading change. During the turn, the nose attitude will have to be raised
slightly above the slow cruise attitude to maintain altitude. Add power as necessary
to maintain airspeed (approximately 2550 ftlbs torque).
As you roll wings level after 210º of heading change, commence a transition to
BAC by lowering the gear and simultaneously lowering the nose to the BAC
descending attitude (2 4 degrees nose down). Retrim as necessary and descend at
120 knots for 500 feet.
During the descent, report each item of the Landing Checklist to your
instructor. Check landing lights on.
One hundred feet prior to the end of the 500 foot descent, transition to level
flight by adding power to 700750 ftlbs torque, raising the nose to the BAC
level flight attitude (approximately 2º nose up), and retrim as necessary.
Note the time and maintain 120 knot level flight for one minute.
After completion of one minute of timing, execute a Missed Approach by:
Advancing the PCL to 1015 ftlbs. and monitor ITT.
Raise the nose to a positive climbing attitude (approximately 6 8º nose up),
