86WG SI(OPS) 03-103 Fuel Planning

Question 1

Minimum preflight fuel calculation includes what fuels?

Answer 1

Taxi fuel
Flight fuel
Alternate fuel
VFR
FFR
Holding fuel (if req’d)
Contingency fuel (if req’d)
AAR fuel (if req’d)
Isolated airfield fuel (if req’d)

Question 2

State standard taxi fuel allowance and what it provides

Answer 2

600kg
Provides 1.5 hours APU burn (200kg/hour) and 12 mins taxi time (1500kg/hour).

Question 3

What shall alternate fuel include?

Answer 3

500kg for the go around
Fuel to climb to cruise
Fuel for cruise from TOPC to TOPD
Fuel from TOPD to 1500ft above field
Fuel for approach (500kg)
An additional 10% of the above totals as alternate VFR

Question 4

Define VFR

Answer 4

Variable fuel reserve to account for unexpected increased fuel consumption. VFR shall be 10% of planned flight fuel to a maximum of 2000kg.

Question 5

Define FFR

Answer 5

Fixed fuel reserve to allow holding for 30 mins at holding speed 1500ft above airfield elevation. A conservative value of 3000kg can be used as the FFR.

Question 6

Define contingency fuel and when it is required?

Answer 6

Contingency fuel permits the plane to descend following an engine failure or depressurisation and proceed to the nearest adequate airfield, assuming the event happens at the most critical point.
It is only required if the minimum amount of fuel calculated for the flight doesn’t allow such an event.

Question 7

Define isolated airfield fuel and what it negates

Answer 7

The fuel required to hold for 2 hours, up to a maximum of 9000kg. Holding isolated airfield fuel negates the need to hold FFR, alternate fuel and holding fuel.
