Basic Instrument Maneuvers
Instrument Flight
Once established at 200 KIAS, trimmed, and on assigned heading, begin the maneuver using a 3 second
lead on the clock and simultaneously initiating a timed 1/2 SRT and timed 1,000 fpm descent. Adjust the
AOB and 200 KIAS descent rate to arrive at the transition point of the descent or climb on time and on
heading. (Approximately 3 seconds prior to the twelve oclock position, 5 degrees short of the 90 degree
turn, and 50 ft prior to the end of the 1,000 ft descent.) At the transition point begin 200 KIAS, 1,000 fpm
rate climb while continuing the 1/2 SRT in the same direction for another 90 degrees of turn. During the
climb adjust AOB to maintain rate of turn and power and pitch to maintain 200 KIAS, 1,000 fpm climb on
the clock.
At the appropriate lead point of the climb, simultaneously reverse 1/2 SRT for another 180 degrees of turn
and begin the 1,000 fpm descent on the clock. The maneuver is complete at the end of the second climb.
Use the same checkpoints on the clock as used for the timed turn 1/2 SRT and S-1 pattern timed climbs
and descents. Trim throughout the maneuver to keep pressure off the stick.
Power setting: Climb approximately 1500 pph; Descent approximately 700 pph
Pitch: Climb = 2-3 degrees noseup; Descent = 1-2 degrees nosedown
Bank angle: Adjust to maintain 1/2 SRT and reverse turn at start of each descent
Airspeed: 200 KIAS
Heading: 90 degrees of change for each climb and descent
NOTE: If you get ahead of the turn schedule reduce AOB so to arrive on heading and on time. Always
begin reversal turn with descent on the clock.
