When you move a zone temperature control up, what are you asking the system to do?

A

add warm trim air (bleed air)

87
Q

A

its slower ( 20 sec from full closed to full open)

96
Q

What would cause an AUTO FAIL light to illuminate?

A
  • an excessive rate of cabin change (+/- 2000fpm)
  • loss of DC power
  • controller fault
  • outflow valve problem
  • high cabin pressure (> 8.75psi)
  • high cabin altitude (15.800ft)
97
Q

What does the HIGH ALT LDG Option Switch do?

A

reprograms the initiation of the cabin altitude warning horn from 10.000ft to 12.500ft
