If the landing gear is not down and locked when the aircraft is
positioned/configured to land an aural "LANDING GEAR" alert will play
and gear position will be displayed in red color with a solid red box
around the gear indications. Logic inputs to the landing gear warning
system include the landing gear position, landing gear switch position,
flap position, aircraft altitude/height, airspeed, and thrust lever angle.
Under certain conditions the aural alert can be silenced by
acknowledging the alert, under others the alert will continue to play but
at a reduced repeat rate.
