US 2021/0197979 A1 · SYSTEM AND METHOD FOR AUTOMATICALLY INITIATING STOPPING OF AN AIRCRAFT ENGINE

Abstract

Methods for automatically initiating stopping of an engine of an aircraft at a desired engine-stop speed are disclosed. An embodiment of the method includes receiving data indicative of a current speed and a current acceleration of the aircraft, the current speed being different from the engine-stop speed of the aircraft. Using the received data, an initiation time at which to initiate stopping of the engine to cause the engine to stop substantially at the engine-stop speed of the aircraft is determined. Stopping of the engine is automatically initiated at the initiation time.

Dependent claims

A method for automatically initiating stopping of an engine of an aircraft at a desired engine-stop speed of the aircraft during testing of the aircraft, the method comprising:

receiving data indicative of a current speed and a current acceleration of the aircraft, the current speed being different from the engine-stop speed of the aircraft;
determining, using the received data, an initiation time at which to initiate stopping of the engine to cause the engine to stop substantially at the engine-stop speed of the aircraft;
and
automatically initiating stopping of the engine at the initiation time.

1 more element

A method of operating a multi-engine aircraft when determining a minimum control speed on the ground (VMCG) of the aircraft at which a lateral deviation of the aircraft does not exceed a prescribed lateral distance after an engine failure, the method comprising:

while the aircraft is accelerating on the ground and is propelled by a plurality of engines, receiving data indicative of a current speed and a current acceleration of the aircraft, the current speed being lower than an estimated VMCG of the aircraft;
and
based on the received data, automatically initiating stopping of one of the plurality of engines to cause the one engine to stop substantially at the estimated VMCG of the aircraft while the aircraft is propelled by the remaining of the plurality of engines.
