Basic instrument maneuvers — attitude flight and recovery from unusual attitudes
**Attitude instrument flying** is the foundation of recovery from inadvertent IMC. The control-performance method uses two sets of instruments:
• **Control instruments** — attitude indicator (pitch and bank) and power indicator (MP or RPM). • **Performance instruments** — altimeter, airspeed, VSI, heading indicator, turn coordinator.
Scan pattern (radial/selective): start at the attitude indicator, sweep to the relevant performance instrument, return to attitude. Avoid fixation on any single instrument.
**Recovery from unusual attitudes:**
• **Nose-high** (airspeed decreasing, altimeter/VSI climbing): add power, lower the nose, level the wings.
• **Nose-low** (airspeed increasing, altimeter/VSI descending): reduce power to prevent over-stress, level the wings, then gently raise the nose. Reversing the order risks over-G or secondary stall.
**VFR-into-IMC** is a top cause of fatal GA accidents. 14 CFR 61.109 requires 3 hours of basic instrument training for the PPL. If inadvertent IMC is encountered: trust the instruments, make a 180° turn (standard rate, timed for 1 minute = 180°), climb if needed for MEA/terrain, declare to ATC. Somatogravic illusions and the leans can make bodily sensations profoundly misleading — believe the gauges.
