Pressurization

Question 1

During an inflight abort immediately after take-off what will your altitude controller do if it detects a descent below 6000’?

Answer 1

The controller will retain the takeoff field elevation in its stored memory for 10 minutes. If the controller detects a descent of 1000’ below 6000’ the controller will establish the cabin on a descent schedule at 375FT per min.

Question 2

During take off how will the controller rate the cabin on take off climb schedule?

Answer 2

When the controller detects >82%TLA (on t/o) it will rate the cabin down 150’ to prevent “bump” on take off.

Question 3

With Cabin Altitude select < or = to 8000’

Name the protection and warning response at 8,600’

Answer 3

PRESS SYS light, Fault light+manual mode auto select

Question 4

With Cabin Altitude select < or = to 8000’

Name the protection and warning response at 8,750’

Answer 4

PRESS SYS light illuminates (if already in Manual mode)

Question 5

With Cabin Altitude select < or = to 8000’

Name the protection and warning response at 9,500’

Answer 5

Emergency pressurization (automatically activates) 
EMER PRESS illuminates

Question 6

With Cabin Altitude select < or = to 8000’

Name the protection and warning response at 10,100’

Answer 6

Cabin altitude warning horn activates
-initiate emergency descent
-mute horn with mute switch
CABIN HI light will illuminate

Question 7

With Cabin Altitude select < or = to 8000’

Name the protection and warning response at 13,700’

Answer 7

Cabin altitude limiters (outflow valves) close shut

Question 8

With Cabin Altitude select < or = to 8000’

Name the protection and warning response at 14,500’

Answer 8

Pax O2 mask deploy

Cabin overhead lights illuminate

Question 9

With Cabin Altitude >8000ft

Name the protection & warning response at 14,500’

Answer 9

Everything happens except Cabin Altitude limiters
