inhibits the auto return feature
95
How does the operation of the outflow valve in manual compare with the operations in AUTO?
its slower ( 20 sec from full closed to full open)
96
What would cause an AUTO FAIL light to illuminate?
- 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)
