Aircraft engine deactivation apparatus
First Claim
1. Safety apparatus for stopping an engine on a propeller driven aircraft comprising:
- detector means mounted on the aircraft for detecting an object within a selected distance from the engine; and
engine deactivation means controlled by said detector means for stopping an engine upon detection of an object within said selected distance.

Abstract
Aircraft engine deactivation apparatus for stopping an aircraft engine while the aircraft is on the ground. The apparatus is for safety purposes and is used to prevent a detected object from coming into contact with an engine driven propeller or a jet propulsion intake. A detector, preferably an infra-red radiation sensor, detects an object or person within a selected distance and within a seleced area about the engine. Upon detection, a mechanical engine deactivator, such as brake calipers engageable with the engine flywheel, or an electronic deactivator, such as an electronic switch operable to ground magnetos, shuts down the engine. A by-pass switch renders the system inoperable, when desired.
