Engine Failure: After Takeoff and at Altitude

Abnormal and Emergency Considerationsdraft — pending CFI review

Why this matters in flight: An engine failure is the emergency student pilots drill most, because the correct first actions are reflexive and time-sensitive. What you do in the first few seconds — and whether you have the altitude to do it — decides the outcome.

Engine failure is handled very differently depending on when it happens. Just after takeoff, altitude and options are minimal, so the rule is to lower the nose immediately to hold best glide airspeed and, in most light airplanes, land essentially straight ahead within a narrow arc. The tempting turn back to the runway at low altitude invites a stall/spin and is usually not feasible below an altitude your instructor and the manufacturer establish. At altitude the picture is calmer because time is on your side. The priority order is the same everywhere: fly the airplane first by establishing and holding best glide airspeed, which gives the greatest distance for the altitude you have. Only then do you pick a suitable field — judging length, surface, slope, and wind, ideally landing into the wind — and run the restart flow. Best glide is a specific published speed; flying faster or slower steepens the descent and shortens your reach. If altitude permits, the restart flow checks the likely culprits — fuel on the fullest tank, mixture rich, carburetor heat or alternate air on, fuel pump on, magnetos checked — always per the aircraft flight manual, aiming to restore power before you commit to a forced landing.

Key terms

Best glide airspeed
The published speed giving the greatest gliding distance per foot of altitude lost.
Land straight ahead
The low-altitude engine-failure response that avoids a risky turn back to the runway.
Restart flow
A memory check of fuel, mixture, carb heat, pump, and magnetos to restore power.

Summary

Low after takeoff: nose down to best glide and land straight ahead. At altitude: best glide first, then field, then restart flow. Best glide maximizes reach, and the restart flow hits the likely causes of power loss.
