V-PREFLIGHT PLANNING

Question 1

IFR OPERATING MINIMAS

Answer 1

MTO conditions above minimas +/- 1h ETA

Question 2

VFR OPERATING MINIMAS

Answer 2

MTO must be ok with VFR rules

Question 3

MINIMUM FLIGHT ALTITUDE

Answer 3

Must not be less than those of the state overflown

Calculation should consider:

• accuracy of the position of the a/c
• accuracies of the altimeters
• characteristics of the terrain
• probability to meet bad MTO
• airspace restrictions

Question 4

T/O ALTERNATE AÉRODROME

Answer 4

• aérodrome where an a/c can land shortly after t/o.
• 2 engines a/c : flight time 1h
• 3 or + engines a/c : flight time 2h
• ETOPS a/c : flight time 2h at 1 engine inop
• MTO at or above minimas ok +/- 1h

Question 5

En-Route ALTERNATE AÉRODROME

Answer 5

• 1 for departure (if required)

- 1 for destination

Question 6

ETOPS EN-Route ALTERNATES

Answer 6

• Sufficient alternates must je selected to remain in the ETOPS circles
• at least 1 Instrument Approach Procedure)
• MTO ok +/- 1h

Question 7

DESTINATION ALTERNATE

Answer 7

=> mini 1 for IFR flights UNLESS:

1) flight time < 6h
2 runways avail.
MTO +/- 1h ceiling 2000ft or circling height +500ft
visibility 5km

OR

2) destination isolated without alternates: FUEL:
TRIP+CONTINGENCY+2h at CRUISE

Question 8

PRECISION APPROACH

Answer 8

CAT I:
DH>200ft
RVR>550m

CAT II:
DH >100ft <200ft
RVR >300m

CAT III A:
DH <100ft
RVR >200m

CAT III B:
DH <100ft or no DH
RVR >75m <200m

Question 9

NON PRECISION APPROACH

Answer 9

• instrument approach with MDH or DH >250ft et >750m when flying continuous descent final approach technique (CDFA)

Question 10

FUEL AND OIL REQUIREMENTS

Answer 10

TAXI FUEL: startup and taxi
TRIP FUEL: T/O to landing
RESERVE FUEL: greater of A or B
A: 
5% trip fuel (3% if en route diversion avail.)
20min flying time 
Amount based on statistical method
B:
5min holding at 1500ft above dest. 

ALTERNATE FUEL: from diversion to alt. Landing
FINAL RESERVE: 
- Turbines: 30min at 1500ft
- Reciprocating: 45min at 1500ft
ADDITIONAL FUEL: 15min 1500ft
EXTRA FUEL: discrétion of commander
