Pitch, power, and trim control inputs that are required to operate the airplane in level flight, turns, climbs, and descents and how the control inputs change at various airspeeds between cruise airspeed and critically slow airspeeds.
Bottom line
Flight in the region of reversed command means flight in which a higher airspeed requires a lower power setting and a lower airspeed requires a higher power setting to hold altitude.
Key numbers
| Number | What it means |
|---|---|
| 1,500 feet AGL for single-engine airplanes (3,000 feet AGL for multiengine), or higher if recommended by the manufacturer | Slow flight floor |
| approximately 5–10 knots above the stall speed for that flight condition | Target slow speed |
| medium-banked turns of approximately 20 degrees | Slow flight turns |
