This is an actual video of an airplane landing with only the left propeller while the right propeller is stopped, taken from 100 meters from the runway. This is the kind of video we would like you to use in pilot training classes, so please take a look. At around 11:00 a.m. on July 28, 2024, ANA Itami to Matsuyama flight (NH1639) declared a "state of emergency" due to engine trouble and returned to Itami Airport. The aircraft was a Bombardier DHC-8-402, and there were 79 passengers and crew on board, but it was reported that no one was injured. 1. Single-engine flight Twin-propeller aircraft are designed to fly safely even if one engine fails, and can continue to fly and land safely as long as the other engine remains. Regarding engine torque and operation, pilots use the rudder to compensate for the effect of torque. During single-engine flight, the airplane's climbing ability and cruising speed may be limited. 2. Emergency Declaration An aircraft that has been declared an emergency has priority over all other aircraft. Air traffic controllers will secure the best route and ensure a quick and safe landing. 3. Airport Response The airport will take all possible measures, such as securing a runway and arranging emergency vehicles.

This is “actual footage” of the moment the plane lands with only the left propeller while the right propeller remains stationary, shot from a position 100 meters from the runway. This is the kind of footage that we would like you to use in your pilot training classes, so please take a look.

For engine torque and operation, the pilot uses the rudder to compensate for torque effects. During one-lung flight, the airplane's ability to climb and cruise speed may be limited. 2. declaration of an emergency An aircraft that has been declared an emergency has priority over all other aircraft.
