System capable of completing the specified
phases.of.an.operation.following.the.failure.of.any. single.system.component.after.passing.a.point. designated.by.the.applicable.safety.analysis.(e.g.,. Alert.Height).
System.which,.in.the.event.of.a.failure,.causes.no.
significant deviation of aircraft.
A.single.failure,.should.not:..
( 1 ) Cause significant displacement of the aircraft
from.its.approach.path.or.altitude.loss.below.the. nominal.glidepath... (.2.).Upon.system.disconnection,.involve.any.out-of-trim.condition.not.easily.controlled.by.the.pilot...
( 3 ) Cause any action of the flight control system
that.is.not.readily.apparent.to.the.pilot,.either.by. control.movement.or.advisory.display.
