-Rudder pedal jam
-Yaw damper system fault
-Rudder travel limit system fault
-All failures leading to loss of nose wheel steering (HYD yellow system loss, double hydraulic failure, double BSCU fault, double LGCIU fault)

74
What the maximum negative differential pressure for the cabin?

107%
80
What’s the maximum EGT for a running APU?

Perform a normal APU shutdown
82
If you have a dual engine failure what’s the maximum altitude at which you can start the APU? What if you still have engine running?
A battery restart, which would be required during a dual engine failure, can only be accomplished at or below 25,000MSL. If you have electrics, i.e. you have at least one engine driven generator working, you can start the APU at or below 39,000MSL.
83
What’s the maximum altitude at which the APU can be used to assist an engine start?
20,000’MSL
84
What’s the maximum altitude at which the APU can supply electrics and both packs? What about electrics and a single pack?
Electrics and both packs: 15,000’MSL
Electrics and a single pack: 22,500’MSL
85
Can you perform a VOR or VOR/DME approach in NAV mode?
Yes, but you must have GPS PRIMARY or NAV ACCOUNT HIGH, and the NAVIAD must be hard tuned and monitored, as it’s the primary source of navigation
86
Can you use the autopilot to fly a non-precision approach with an engine-out?
Yes, unless you are in A/C 701-712. Those aircraft are approved for FD use but the autopilot must be off for non-precision approaches with an engine-out.
87
Can you perform an RNAV (GPS) approach without GPS PRIMARY?
Yes, but you must have NAV ACC HIGH
88
Can you perform an RNAV (RNP) approach without GPS PRIMARY?
No. Not even with NAV ACC HIGH.
89
What may you want to do if you suspect GPS spoofing?
You can deselect the GPS position on the SELECTED NAVAID page. This will force the aircraft to solely rely on the radio position.
90
When will the FM position not automatically update to the runway position during takeoff?
When GPS primary is active (see Vol 3)
91
What should be done to ensure an accurate takeoff update if departing from an intersection?
Enter the takeoff shift on the PERF TO page to refine the takeoff update. This is only necessary if an intersection wasn’t already inserted.
92
Can the FMS landing system (FLS) mode be used during approaches?
No. At least not yet. From what I understand that will be changing at some point in the future. Apparently the FLS mode will allow us to use LPV minimums, from what I understand. Don’t quote me.
93
Who is always the PF and PM for autoland approaches?
PF: Captain
PM: First officer
94
Can autoland approaches be done in flaps 3?
Yes
95
Why is it recommended to do autoland approaches in flaps full vs flaps 3?
Flaps full provides better forward slant range visibility
96
If one of the autoland criteria cannot be met, can we fly a CAT 1 down to minimums?
Yes
97
What’s the highest autoland altitude for A/C 701-799?
5,750’ airport altitude
98
What’s the highest altitude for an autoland in A/C 200’s, 300’s, and 600’s?
9,200’ airport elevation
99
Can autoland procedures be done when the weather is better than 2sm visibility and 800’ ceilings?
Yes, but in these circumstances ATC does not protect the ILS critical area, so you’ll need to advise them of your autoland attempt and to protect the ILS critical area. This is done by ATC on a workload permitting basis. If they are unable to protect the ILS critical area you may still make the attempt but should be ready to immediately disconnect the AP and take appropriate action should the guidance become unsatisfactory.
100
Can you continue an auto land approach if the aircraft wind vector says the winds are outside if limits, if the tower reports winds within limits?
Yes

140ºC continuously, 155ºC on a transient basis.
107
What is the maximum engine oil temperature in a 600 series aircraft?
151ºC
108
For 200 and 700 series aircraft, how long to you need to wait between subsequent start cycles? How many cycles need to be failed before you need to let the engine cool down? How long does it need to cool down for?
-A 20 second pause is required between start cycles, automatic or manual
-After 4 failed cycles the engine needs a 15 minute cooling period
109
For 300 series aircraft, how long to you need to wait between subsequent start cycles? How many cycles need to be failed before you need to let the engine cool down? How long does it need to cool down for?
-A 60 second pause is required between start cycles, automatic or manual
-A 15 minute cool down period is required after 3 failed cycles
110
For 600 series aircraft, how long to you need to wait between subsequent start cycles? How many cycles need to be failed before you need to let the engine cool down? How long does it need to cool down for?
-A 35 second pause is required between start cycles, automatic or manual
-A 15 minute cooling period is required after 3 failed cycles
111
During an automatic engine start, how many start attempts is considered one cycle?
Depends on the aircraft…
600 series: two start attempts
All other aircraft: three start attempts
112
Does OEB57 apply even if it’s not in the QRH?
OEB57 no longer applies to our aircraft
113
What is the fuel system accuracy requirement per FAR part 25?
At very low fuel quantities (5% of tank capacity), the amount of fuel on board will always be equal to or greater than indicated. Another way of saying this is that the indication will read less than what you actually have on board once you reach 5% of tank capacity. Above 5% o tank capacity the fuel system indication is generally greater than what’s on board, and the error is generally greater at higher fuel loads.
In short, the fuel quantity indication only has to be accurate at “E”
114
When is ice accretion considered severe?
When you reach 5mm (or 0.2”) of ice accretion
115
What’s the maximum taxi seed with a tire deflated?
1 tire per gear: 7 knots
Both tires on the gear: 3 knots
116

At or above 1339 PSI
118
In 300 and 600 series aircraft, above what O2 bottle PSI do you never need to worry about it being enough for departure?
At or above 800 PSI per bottle
119
How do you find the reference temperature for determining if the O2 bottles have sufficient PSI on the ground?
(OAT + Cockpit temp)/2
