deadstick landing

A deadstick landing is an emergency landing where an aircraft descends without engine power. The pilot controls descent and direction using only aerodynamic surfaces: the control surfaces, wing geometry, and gravity. No thrust is available from the engines, whether because they have failed, been shut down, or run out of fuel. The aircraft must reach a suitable landing surface before losing enough altitude to become uncontrollable.

The term reflects practical reality. A "stick" (the control yoke or stick) works to manage pitch and roll during descent, but the engines are "dead." A skilled pilot can stretch glide distance by managing airspeed precisely, typically aiming for a shallow descent angle that balances forward speed with altitude loss. For fixed-wing aircraft, glide ratio depends on aerodynamic efficiency: a light, high-efficiency aircraft might achieve a glide ratio of 15:1 or better, meaning it descends one foot for every 15 feet forward, while heavier or less efficient aircraft may manage only 5:1 or 8:1.

Deadstick landing is distinct from a normal glide descent, which is a planned maneuver for descent under power management. A deadstick scenario is unplanned and unwanted. It differs from a water landing or off-field landing, which describe where the aircraft comes to rest rather than how it gets there. Rotorcraft (helicopters) face different dynamics because rotor inertia provides some lift even without engine power, though autorotation requires specific technique and conditions to succeed.

For maintenance crews and investigators, a deadstick landing event signals potential engine failure, fuel system problems, or electrical failure that stopped the engines. Post-landing inspection focuses on whether the engines were actually producing power at the moment of touchdown, whether fuel was available, whether ignition was active, and whether the pilot followed proper restart procedures during descent. Evidence from engine teardown, fuel system analysis, and cockpit voice recordings determines the cause.

The ability to recognize and execute a deadstick landing is part of pilot training, but it remains an emergency procedure. Modern aircraft systems include redundancy in fuel supply, ignition, and sometimes engine restart mechanisms specifically to reduce deadstick scenarios. Nevertheless, structural damage, fuel contamination, or complete loss of electrical power can still force the situation. The term remains essential vocabulary in accident investigation and maintenance troubleshooting.
