If the outer tanks are balanced what is the max asymmetry in the inner tanks for takeoff
500kg with the heavier tank full
1450kg if the heavier tank only has 1450kg
Max fuel asymmetry for takeoff in outer tanks if inner tanks balanced
370kg
Max fuel imbalance in flight and at landing, inner tanks with outer tanks balanced
Heavy tank full = 1500kg
Heavy tank down to 2250kg =2250kg
No limitation below 2250kg
Max fuel imbalance in flight and at landing, outer tanks with inner tanks balanced
One can be full with one empty as long as:
Total fuel on one side = total fuel on other side,
or
On the side of the lighter outer tank, the quantity of the inner is more than the quantity of the opposite inner. The quantity of the inner tanks should be max 3T
Note says plane will still be fully controllable if you go outside this in a fuel system failure
Min fuel quantity for takeoff

Min Oxy pressure covers us for
Minimum Bottle Pressure to Cover:
‐ Preflight checks
‐ The use of oxygen, when only one flight crewmember is in the cockpit
‐ Unusable quantity (to ensure regulator operation with minimum pressure)
‐ Normal system leakage
‐ The most demanding case among the following:
• Protection after loss of cabin pressure, with mask regulator on NORMAL (diluted oxygen):
▪ During EMERGENCY DESCENT for all flight crewmembers and observers for 13 min
▪ During CRUISE at FL 100 for two flight crewmembers for 107 min.
• Protection against smoke with 100 % oxygen for all flight crewmembers and observers during 15 min at 8 000 ft cabin altitude.
When should ROPS be inhibited?
There would be an INTAP.
If selecting TERR pb OFF because of an issue with the GPWS database, for landing don’t do it until within 15nm from AD
What temp do you use to check the OXY pressure against temp in the limitations section?
