KV 2020 External Walk Around Flashcards
Why does the Emergency / Parking Brake need to be on prior to starting the external inspection?
(SOPM Preflight) 87 of 333
To Determine there is sufficient hydraulic pressure to activate the Emergency / Parking Brake to check the Brake Wear Indicators
Just because the parking brake is on, does this guarantee that there is sufficient hydraulic pressure to check the Brake Wear Indicators?
(AOM Vol 2. Landing Gear and Brakes) 975 of 1,110
No -
1. Emergency / Parking Brake Accumulator Pressure Indication
- Digital Pressure
GREEN - Normal operating Range
AMBER - Degraded Effectiveness
AMBER DASHED - Invalid information or value is out of range
-Pressure Scale Pointer
If the pointer disappears - value invalid
-Scale
WHITE - Normal Operating Range
AMBER - Degraded Effectiveness
- Pointer
GREEN (hollow) Normal Operating Range
If the hydraulic pressure is depleted for the brakes, how can it be restored prior to the external walk around?
(AOM Vol. 2 hydraulic) ?
Hydraulic System 1 controls outboard brakes
Hydraulic System 2 controls inboard brakes
Low Pressure
Turn Hydraulic Pump 1 and / or 2 to…….. ON to override system logic to re-pressurize the hydraulic lines to operate the brakes.
