A deadstick landing, also called a dead-stick landing, is a type of forced landing when an aircraft loses all of its propulsive power and is forced to land. The "stick" does not refer to the flight controls, which in most aircraft are either fully or partially functional without engine power, but to the traditional wooden propeller, which without power would just be a "dead stick". When a pilot makes an emergency landing of an aircraft that has some or all of its propulsive power still available, the procedure is known as a precautionary landing.

  • A deadstick landing, also called a dead-stick landing, is a type of forced landing when an aircraft loses all of its propulsive power and is forced to land. The "stick" does not refer to the flight controls, which in most aircraft are either fully or partially functional without engine power, but to the traditional wooden propeller, which without power would just be a "dead stick". When a pilot makes an emergency landing of an aircraft that has some or all of its propulsive power still available, the procedure is known as a precautionary landing. All fixed-wing aircraft have some capability to glide with no engine power; that is, they do not sink straight down like a stone, but rather continue to glide moving horizontally while descending. For example, with a glide ratio of 15:1, a Boeing 747-200 can glide for 150 kilometres (93 mi; 81 nmi) from a cruising altitude of 10,000 metres (33,000 ft). After a loss of power, the pilot’s goal is to maintain a safe airspeed and fly the descending aircraft to the most suitable landing spot within gliding distance, then land with the least amount of damage possible. The area open for potential landing sites depends on the original altitude, local terrain, the engine-out gliding capabilities of the aircraft, original airspeed and winds at various altitudes. Part of learning to fly a fixed-wing aircraft is demonstrating the ability to fly safely without an engine until prepared to make (or actually making) a landing. Gliders, unless they have an auxiliary motor, do all their flying without power, and a trained pilot can touch down on virtually any spot they pick from the air. The success of the deadstick landing largely depends on the availability of suitable landing areas. A competent pilot gliding a relatively light, slow plane to a flat field or runway should result in an otherwise normal landing, since the maneuver is not especially difficult, requiring only strict attention and good judgement concerning speed and height. A heavier, faster aircraft or a plane gliding into mountains or trees could result in substantial damage. With helicopters, a forced landing involves autorotation, since the helicopter glides by allowing its rotor to spin freely during the descent thus generating lift. (en)
  • Un atterrissage sans moteur est un atterrissage d'urgence réalisé par un pilote à bord d'un aéronef dont tous les moteurs sont en panne. L'expression en anglais deadstick landing (littéralement, atterrissage avec un manche mort) vient des débuts de l'aviation, quand un avion en panne moteur atterrissait hélice calée. Un aérodyne ayant perdu la poussée de sa motorisation ne tombera pas forcément comme une pierre. Si le pilote à bord est suffisamment compétent il pourra continuer de voler en planant et en perdant de l'altitude tout en allant vers le sol aussi loin que le permettra la finesse de l'aérodyne. Par exemple, avec une finesse de 15, un Boeing 747-200 à une altitude de 10 000 mètres peut parcourir 150 kilomètres. Parmi les différentes catégories d'aérodyne, les aérogires sont les appareils les moins aptes à réaliser des atterrissages sans moteur. (fr)
  • 無動力着陸とは、プロペラやジェットエンジン等の動力が無い状態での着陸の事である。一般的に、スペースシャトルやグライダーのような無動力滑空機の着陸ではなく、ジェット機やプロペラ機での不時着で使用される用語である。 英語ではデッド・スティック・ランディング(英語:deadstick landing、dead-stick landing)と呼ばれる。この「デッド・スティック」は、動力が無くても操縦が(ある程度)可能な操縦桿の事ではなく、機能していない木製プロペラの事を指している。 固定翼機は、大抵は動力が無くても滑空という形で飛行することが可能であり、動力が動いていた時の慣性と揚力を利用してコントロールも可能である。 (ja)
