Q

(757) How does the alternate gear extension system operate?

A

Signals a small electric hydraulic pump to release the

uplocks using trapped left hydraulic system fluid

17
Q

(767) What occurs after selecting the Reserve Brakes and Steering switch?

A

Provides reserve hydraulic fluid to the center number
one (1) electric hydraulic pump regardless of pump
switch position and pump pressure is then supplied
exclusively to the alternate brake system and nosewheel
steering system

18
Q

(767) What is the active brake system following a SYS PRESS light and a R HYD SYS
PRESS EICAS message?

A

Alternate brakes powered from the center hydraulic

system

19
Q

(767) How does the alternate gear extension system operate?

A

An electric motor is used to trip the locking mechanism

for each gear

20
Q

(767) What number activates the BRAKE TEMP light?
