Normal (non-emergency) position - supplies air/oxygen mixture or 100% oxygen
on demand, depending upon the position of the Normal/100% switch.
Automatically supplies 100% oxygen under positive pressure when cabin altitude
is above a preset value.
EMERGENCY position (rotate in the direction of the arrow) – supplies 100%
oxygen under positive pressure at all cabin altitudes (protects against smoke and
harmful vapors).
PRESS TO TEST– tests the positive pressure supply to the regulator.

Exterior Lighting
Exterior lighting consists of these lights:
Landing Lights
The landing lights consist of the left, right, and nose gear landing lights. The left
and right landing lights are located in the left and right wing root. These lights are
optimized for flare and ground roll. The two nose gear–located landing lights are
optimized for approach.
Runway Turnoff Lights
Runway turnoff lights are installed in the left and right wing roots. The lights
illuminate the area in front of the main gear.
Taxi Lights
Taxi lights are installed on the non–steerable portion of the nose strut. They are
inoperative when the nose landing gear is not down and locked.
Strobe Lights
The strobe lights are white anticollision strobe lights located on each forward wing
