Can an autoland be done on a “narrow runway”?
No. A narrow runway is anything less than 148’ wide. Only the 600’s and 227-229 can land on those runways, but even those planes cannot autoland on a narrow runway.
When is dispatch to and from a narrow runway (less than 148’ wide) not authorized?
-Nose wheel steering is inoperative
-One or more brakes are inoperative
When is it recommended that you divert to a regular runway when you were originally dispatched to a “narrow runway”?
Basically anything that affect the rudder in any way:
-Rudder jam
-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)

10 knots for takeoff and landing
What is the maximum wind for passenger door operation?
65 knots
What the maximum negative differential pressure for the cabin?
-1.0 psi
What’s the maximum differential pressure for the cabin? When should the safety relief valve open?
Absolute max is 9.0 PSI. The safety should open at 8.6 PSI.
Can you use the high pressure air from an external HP cart to supply the packs for air conditioning?
No. It’s prohibited.
What’s the maximum time that the electrical systems of the aircraft should remain powered, without an avionics cooling system working, and when the outside air temperature exceeds 49ºC?
2 hours
Above what outside air temperature should you really become concerned for the avionics if the avionics cooling system isn’t working?
Above 49ºC the aircraft must be de-powered with no avionics cooling for more than 2 hours
What’s the APU max rotor speed?
107%
What’s the maximum EGT for a running APU?
675ºC
What should you do if you have a fuel spill with the APU running?
Perform a normal APU shutdown
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.
What’s the maximum altitude at which the APU can be used to assist an engine start?
20,000’MSL
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
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
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.
Can you perform an RNAV (GPS) approach without GPS PRIMARY?
Yes, but you must have NAV ACC HIGH
Can you perform an RNAV (RNP) approach without GPS PRIMARY?
No. Not even with NAV ACC HIGH.
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.
When will the FM position not automatically update to the runway position during takeoff?
When GPS primary is active (see Vol 3)
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.
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.
Who is always the PF and PM for autoland approaches?
PF: Captain
PM: First officer
Can autoland approaches be done in flaps 3?
Yes
Why is it recommended to do autoland approaches in flaps full vs flaps 3?
Flaps full provides better forward slant range visibility
If one of the autoland criteria cannot be met, can we fly a CAT 1 down to minimums?
Yes
What’s the highest autoland altitude for A/C 701-799?
5,750’ airport altitude
What’s the highest altitude for an autoland in A/C 200’s, 300’s, and 600’s?
9,200’ airport elevation
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.
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

-A 35 second pause is required between start cycles, automatic or manual
-A 15 minute cooling period is required after 3 failed cycles
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
Does OEB57 apply even if it’s not in the QRH?
OEB57 no longer applies to our aircraft
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”
When is ice accretion considered severe?
When you reach 5mm (or 0.2”) of ice accretion

At or above 1339 PSI
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
How do you find the reference temperature for determining if the O2 bottles have sufficient PSI on the ground?
(OAT + Cockpit temp)/2
