<p>The present invention is a power lever tactile cueing system (13) for providing tactile alerts to pilots as operational limits of an aircraft (11) are approached. The cueing system (13) generates a tactile cue (C) comprising a variable dive rate (51) and a variable friction force (53) on a power lever (33) of an aircraft. The cueing system (13) provides spring-like tactile cues (C) when power commands reach a predetermined operating limit, without the use of mechanical springs. The cueing system (13) trims down the power lever (33) position and provides the additional friction force (53) based upon aircraft (11) and engine state. The cueing system (13) remains activated until the aircraft (11) is again operated within its operational limits. The pilot may override the cueing system (13) in certain situations.</p> |
