Random 777 questions, part 1
Hi all, I hope I can tap into the knowledge base on this forum to answer a few 777 questions. Thanks in advance for the replies.
1. The door chapter says that at very high differential pressure, the vent flap cannot be opened. How high is very high?
2. Automatic WAI is inhibited when “Takeoff mode is selected” what exactly is takeoff mode? Does this refer to takeoff thrust (THR REF)?
3. Also, why’s WAI inhibited for the first 10 minutes?
4. Our manual states there’s no minimum oil quantity in flight, (but we do have a minimum for dispatch). How’s there no minimum in-flight oil quantity?
5. During a normal APU shutdown, can the shutdown be interrupted in the cooldown phase if you’ve changed your mind and decided to leave it running?
6. Does the APU fire bottle automatically discharge in the event of a fire in unattended mode?
7. In the flight control chapter, it says that in the secondary mode, simplified PFC laws lead to elevator and rudder being more sensitive at “some” speeds. Is this expanded upon anywhere?
