PARKING BRAKE
The parking brake is commanded with the PARK BRK handle. Verify the parking brake is on by checking
the ACCU-PRESS gauge. Normally the aircraft is not parked with the parking brakes applied, but with
chocks to keep it in place. However, during icing conditions, refueling or with high winds parking brakes
are used.
LIGHTING
COCKPIT LIGHTING
Compared to many other airliners the cockpit lighting is very simple and controlled by panels on the front
console and overhead panel.
• INSTRUMENTS and PANEL LIGHTS: ON / OFF (all instruments and panels are integrally lit)
• ANNUNCIATOR LT TEST BRT / TEST.
Switch to TEST to test the functionality of all annunciator lights. Switch back to BRT for standard
operation. DIM setting is ignored.
EXTERNAL LIGHTS
The external lights are controlled by switches on the overhead panel. Please note that some of the lights
(most noticeably landing lights) are not created using the standard P3D lights and do not react to the
standard P3D light commands.
1. BEACON: ON / OFF
2. NAVIGATION: ON / OFF
3. RWY TURN: ON / OFF
4. LANDING: ON (extended
and on)/OFF (extended
and off) / RETRACT
5. NOSE: T.O. (both lights
on) / TAXI (taxi light on) /
OFF
6. STROBE: ON / AUTO (off
when gear on ground) /
OFF
