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.

Turn Pattern. Refer to FAM Stage for a description of the turn pattern.

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.
