Q

Calculate crosswind component

A

Clock Method - 60min = 60 degress - Anything greater the full component is crosswind
45 degrees = 45 min, 3/4 = 3/4 of the wind is the crosswind
30 degrees = 30min, 1/2 hour = 1/2 the wind component ect ect ect…

Q

How do you deal with cold fuel temperatures

A

Fuel additives

Use fuel from center and tail tank as they are less exposed to elements as wing tanks

Q

Wind shear recovering and procedures

A

1) Select Most favorable runway
2) lowest possible flap setting to maximize climb gradient
3) Set predictive wind shear mode on the WX radar for detection
4) Monitor indicated airspeed closly

Recover

1) maximum available thrust
2) Follow flight director guide with predictive wind shear inputs
3) Do not make configuration changes

Q

On 747 is VMCA or VMCG higher

A

VMCG is higher, not allowing 5 degree bank to the live engine to reduce asymmetric force

17
Q

What is ACARS

A

Air Communications and Reporting System

18
Q

V1
Vr
V2

A

V1 - Take off decision speed - Continue to screen height (35ft) within TODA and to abort and stop within TORA

Cannot be less than Vmcg or greater than Vr or Vmbe

Vr - The speed at which rotation will allow V2 by 35ft

Cannot be less than 1.05xVmca

V2 - Take off safety speed in the event of a failure.

Cannot be less than 1.10xVMC or 1.20xVs

19
Q 
V3
Vmca
Vmcg
Vref
Vmbe
A

V3 - All engine screen speed, assumed speed to reach 35ft with all engines running

Vmca - Min control speed in the air
Vmcg - Min control speed on the ground - aerdynamic controls only

Vref - Speed at threshold crossing height (50ft) 1.3xVs

Vmbe - Maximum brake energy absorption speed

20
Q

Long Range Cruise Vs Max cruise power

A

Max Range Cruise - speed for a given weight and altitude where max FUEL MILEAGE is obtained

LRC - speed higher than Max Range Cruise (10kts) which results in a 1% milage loss at contstant alt, LRC requires a gradual reduction in cruise speed as gross weight decreases with fuel burn

Higher Mach No = Higher TAS = Higher GS = Shorter flight time = Higher SFC

21
Q

EGPWS vs GPWS

Inputs and Mode’s

A

GPWS - Radio Alt, VSI, Glideslope
EGPWS - Radio alt, VSI, Glideslope and GPS for predictive mode

Main advantage of EGPWS is the predictive terrain function

MODES

  1. Excessive ROD
    2a. Excessive terrain closure A/C not in landing config
    2b. Excessive terrain closure A/C not in landing config
    (Difference is the heights)
  2. Negative Rate of climb after take-off
    4a. Unsafe terrain - TO LOW GEAR
    4b. Unsafe terrain - TO LOW FLAPS
  3. Glideslope
  4. Minima’s call
22
Q

Optimum Altitude

A

For a given thrust setting will equal the maximum range speed
Cruise alt for min fuel burn at LRC
Increases with reduced weight and a decrease in temp

23
Q

Advantages of the 747-400

A

ETOPS compliant
Greater payload and range than previous models
Greater capacity and range compared to the A340

24
Q

What should you do if a large build up of ice is noticed on the engine intakes

A

Select engine anti ice on individually

25
Q

How does TCAS Work

A

By interrogating the transponders of other aircraft’s to determine there range and relative altitude
