Q

How to calculate density altitude

A
  1. Calculate the pressure altitude at a given point (when QNH is 1013hPa)
  2. Calculate the temp. deviation from ISA (AT PRESSURE ALTITUDE)
  3. Calculate density altitude by applying the correction of 120ft per 1°celsius

Q

Dynamic pressure

A

Like the feeling when you put the hand out of the car’s window. The faster it drives, the more wind you feel on the hand, the more dynamic pressure.

Q

Static pressure

A

Like the weight of the atmposhphere

21
Q

Total pressure

A

Dynamic pressure + static pressure

22
Q

Higher altitude, more / less dynamic pressure?

A

Less. There are less molecules of air

23
Q

CAS

A

Calibrated air speed (indicated corrected for errors in the instrument)

24
Q

Calculating TAS

A
  1. Calculatoe pressure altitude on the date of the flight
  2. Knowing pressure altitude and OAT, calculate TAS
25
Q

True airspeed

A

Calibrated airpspeed corrected for non-standard atmosphere

26
Q

FL20 how much in ft?

27
Q

FL400 How much in ft

28
Q

Curising 95kts at FL70, OAT -9, ASI error -6kt. what is TAS?

29
Q

Destination is 77nm away;
Must arrive in 42 minutes
FL50 OAT+10
What is the appropriate CAS

30
Q

When will GS=TAS?

A

No wind (need to verify)

31
Q

VS0

A

Stalling speed with full flaps

32
Q

Where should you find the maximum headwind and crosswing for an aircraft?

A

POH Pilots operating handbook

33
Q

If maximum headwind or crosswind component not given, whats the formula

A

VS0 * 0.22 = maxium crosswind

34
Q

Wind directions given by ATSU and ATIS or magnetic or nort

35
Q

Need to know:
Calculate TAS from CAS
Calculate drift and t heading (afterwards magnetic heaidng) using wind side of e6b
Calculate maximum crosswind components and headwind using wideside

36
Q

IMPORTANT:
Flying 179°C, with 11° right drift.
C Deviation 4°W
Variation 8°W
What is true track

37
Q

IMPORTANT:
Flying 255° true track, with 7° right drift
Variation 6°E
Deviation 2°W
what is compass heading

38
Q

IMPORTNAT:
Flying 020°C with 5° right drift
Variation 3°E
Deviation 4°W
what is true track

39
Q

IMPORTANT:
Heading 116°T
TAS 130kt
GS 141kt
True track 120°T
What is wind speed and direction

40
Q

7 Types of fuel required, list them

A

  • Trip fuel
  • Contingency fuel
  • Alternate fuel
  • Final reserve fuel
  • Minimum additional fuel
  • (Extra fuel)
41
Q

Taxi fuel

A

Amount of fuel expected to be used prior to takeoff

42
Q

Trip fuel

A

Amount of fuel required for climb, cruise and descent. Must consider arrival procedures at dest. aerodromes

43
Q

Contingency fuel

A

The highest of:
- 5% of planned trip fuel
- 3% of planned trip fuel if an enroute alternate aerodrome is available

44
Q

Alternate fuel

A

For missed approach and landing at alternate detination.

45
Q

Final reserve fuel

A

To fly for an additional 45 minutes

46

Minimum additional fuel

A

To allow for 15 minute holding time

47
Q

Takeoff alternate

A

Alternative aerodrome to land if this becomes necessary after a takeoff and not possible to use deparature aerodrome

48
Q

Enroute alternate

A

Alternative aerodrome(s) if necessary during enroute

49
Q

Destination alternate

A

Alternative aerodrome to land if destination aerodrome not applicable anymore
