JOINT ADVANCED MULTI-ENGINE T-44A
206.
Basic Instrument Patterns. Basic instrument patterns incorporate fundamental airwork into a sequence of
continually changing altitudes, headings and airspeeds. Practicing these patterns develops timing,
precision, and smoothness in control, and develops both full and partial panel scan techniques. In addition
to the FAM standard airspeeds and approximate power settings, use the following for BI maneuvers:
AIRSPEED
PROP RPM
TORQUE (approx.)
CONSTANT RATE CLIMB
500 FPM
150 KIAS
1900
900 FT-LBS.
667 FPM
150 KIAS
1900
1000 FT-LBS.
CONSTANT RATE DESCENTS
500 FPM
150 KIAS
1900
450 FT-LBS.
800 FPM
150 KIAS
1900
350 FT-LBS.
NOTES:
(1)
These power settings are a place to start in finding the correct power for given conditions. Required
power will vary with altitude, aircraft weight, and engine efficiency.
(2)
Begin all patterns on a cardinal heading.
(3)
The elapsed time may be reset and started for each pattern.
(4)
During full panel patterns, AOB will vary if behind or ahead in the turn, but do not exceed a maximum of
30 AOB.
(5)
Full panel patterns roll out on desired heading using the one-third AOB rule. Partial panel patterns roll
out on timing and do not use any lead when rolling out of the turn.
(6)
Pattern diagrams may be utilized for reference if desired.
207.
Turn Pattern. Refer to FAM Stage for a description of the turn pattern.
208.
Level Speed Change. Refer to FAM Stage for a description of the level speed change.
209.
Oscar Pattern. Begin the Oscar pattern at 1900 RPM, 150 KIAS for one minute. Make a standard rate
360 turn to the left while climbing 1000' and maintaining 150 KIAS. At the completion of the turn, fly
straight and level for one minute at 150 KIAS, then make a 360 standard rate turn to the right while
descending 1000' and maintaining 150 KIAS. Constant airspeed, trim, small attitude adjustments, and
altimeter, heading, and clock cross checks are essential. Attempt to maintain a constant 500 FPM rate and
constant SRT once established.
(1) Refer to Figure 2-1.
(a) Straight and level (1 min.)
1. 650 ft-lbs. torque (approx.)
2. 150 KIAS
(b) Climb 1000' at 500 FPM while executing a left SRT for 360 (2
min.)
1. 900 ft-lbs. torque (approx.)
2. 150 KIAS
(c) Transition to straight and level (1 min.)
1. 650 ft-lbs. torque (approx.)
2. 150 KIAS
