What is the PTU
Power transfer unit, it will turn on when flaps are out of 0 gear not up and locked Edp 1 is working Hyd Sys 2 quantity above 12%
It uses sys 1 pressure to help lower or raise gear when the #2 EDP is not working.
There is no exchange of fluid though
Does Fadec provide Start Protection
Yes for
Hot
Hung
No lightoff starts
How do you dry motor the engine
turn off the ignitors
what is the elec power priority
Onside IDG
Backside APU
outside GPU
cross side other IDG
What is Stab trim priority
Backup
Captain
FO
Autopilot
What kind of Brakes do we have and why
Carbon,
They are much lighter and wear much less at high temps
i.e. use higher force and less frequent application
dont’ drag brakes
How many brake applications with the emergency parking brake
6
How long will ice pro remain on after ice is detected
5 mins, supposedly changing to 2 minutes
On ground, with only the Apu on will your windshield be heated
No, only for 120 seconds during the elec pbit test
both are heated when you have 2 AC sources
Is the DV window heated
No
In flight with only one AC source will your window work
what about the FO’s
yes,
the FO’s will only work if the captains fails
When will autothrottle engage on takeoff

What will the bank button do
limits bank to 17 degrees, but only in heading mode

you can ‘t
Why do you turn the fuel xfeed switch to low 1 on the dual engine failure
To turn on the DC fuel pump,
What does the APU emer stop button do
closes the fuel shutoff valve to apu,
no cooling down period
Why is Batt 2 an auto switch
Automatically isolates APU start bus during APU start, and is a locked backup for all 3 DC ESS busses when BATT 1 fails
What do you have left in Elec emergency
Screens 2 and 3 CA DRP, compass light IESS Clock MCDU 2 CA's CCD Both ACP's but only Comm 1/ Nav 1
How do you know if you are within the engine airstart envelope
WML icon next to N1
what happens if you hold the fired detection button for 10 seconds
shuts down APU
how long does the IESS take to stablize
90 seconds, don’t move

cabin alt 14,000-14,750
how long will pax o2 last once activated
12 minutes
what is the biggest thing missing from the T/O config check
Whether or not both engines are running
what is best climb rate
Vfs +50 to clear wx
What is best climb angle
Vfs to clear obstacles
why should you only shutdown an engine while taxiing straight ahead
to avoid interruptions the steering when sys 2 is momentarily depowered
How much fuel in collector tanks
660lbs
can you use FMS speeds when OEO
no
Why do we fly 150kts min with the RAT out
to provide a buffer over the 130 kt limit
Where do you have windshear guidance
10-1500agl
