What powers the thrust reversers> (are they electric, hydraulic, pneumatic?)
Hydraulics
On landing, will the speed brakes deploy if the handle is not in the armed position?
Yes but only with activation of reverse thrust
With AUTOSTART ON, placing the FUEL CONT switches actuates what two valves and one other thing
Opens the spar fuel valve and arms the engine fuel valve and the selected ignitors
With AUTOSTART ON, what opens the engine fuel valve? What else does it do?
The Electronic Engine Control (EEC). It also energizes the selected ignitor or igniters
In the NORM position, what do the EECs use as the normal parameter to set thrust?
EPR
If the EECs are in alternate mode, what do they use as the controlling parameter to set thrust?
N1
When the FUEL CONT switch is in cutoff or the N2 is below idle what is the second red tick on the EGT gauge?
The EGT start limit
When would the EGT Amber indication be inhibited?
Takeoff and go-around
When the in-flight engine restart envelope is displayed it shows what altitudes?
The lower of the current altitude or the Max in-flight start altitude of FL330
On the vibration gauges what does BB mean and when would it be displayed?
Broad Band
When the source of vibration is unknown (compared to if it is a N1 or N2 issue)
Is there a certified engine vibration limit?
No
How would you know that a cross-bleed start is required?
A magenta crossbleed symbol (XB) will be displayed next to the N2 indication
Where do the EEC get input from?
Thrust Lever inputs
What are the two EPR control modes and what do they use for setting thrust?
Normal - EPR
Alternate - N1
What is “soft alternate” mode of the EECs?
will autothrottles remain engaged?
When the required signals for the normal mode are not available and the EECs automaticity switch to alternate
Yes
When in soft alternate mode what do you do to ensure that both thrust levers are scheduled equally?
Follow the checklist to schedule a hard alternate mode reversion
EEC Alterante Mode
Is thrust limit protection provided in either soft or hard alternate mode?
No, if you aren’t careful you could overboot the engines
When in normal mode how do the EECs provide overspeed protection?
by reducing fuel flow
What are the two idle settings?
Minimum or approach idle
When would approach idle be activated?
(two common, two uncommon)
-Engine Anti-ice operating
-Flaps to 25 or greater
-One air-driven Hydraulic demand pump inop and flaps not up
-The opposite engine bleed air valve is closed
Which ignitor is used for each start?
on the ground?
Inflight?
The EECs alternate ignitors for each start. Both igniters are used for inflight starts
Does the autostart system monitor oil pressure and temperature?
NO
Where is oil pressure and temperature measured reference the engine? (before or after entering the engine)
Pressure is measured before it enters the engine
Temperature is measured after it leaves the engine
What is the maximum and minimum tank fuel temperature for Jet-A?
49 degrees C
-37 degrees C
