airborne. The safety switch on the nose strut enables the rudder shakers in flight and the beta

release while on the ground.

Position Indicator Switches

Position indicator switches are micro type switches located in the wheel wells. These switches

activate the gear position indicators in each cockpit and the external down position indicator

lights. The left main landing gear UP position switch activates the air conditioner condenser

blower any time the gear is not up and the air conditioner is operating. The nose landing gear UP

position switch activates the landing light fault light and the master caution light when the gear is

up and the landing lights are on.

1903. LANDING GEAR WARNING SYSTEM

The landing gear warning system consists of a horn behind the front seat, a 1000-Hz audio tone

in the ICS, a steady red light in the landing gear handle and a flashing red landing gear WHEELS

warning light on the instrument panel. This system is designed to alert the pilot of an unsafe

condition and will be activated if any of the following conditions exist:

The warning horn and audio tone may be silenced, but only under certain power-off conditions--

noted by "(S)" in the chart. When allowed, silencing is accomplished by depressing the button

(Figure 19-3) labeled WARNING HORN SILENCE, adjacent to the landing gear handle. This

does not affect the warning lights.

Position Indicator

The position of the landing gear is shown by three individual indicators, one for each gear,

located on the instrument panel in both cockpits, lower left side, just to the right of the gear

handle. Each indicator can display any one of following three conditions.

Cross-hatching (barber pole) related gear is in any unlocked position (gear in transit, not

down and locked or not up and locked) or the electrical system is not energized.

The word UP displayed - related gear is up and locked.
