TORA
Take-Off Run Available = The length of runway declared available and suitable for the ground run of an airplane taking off
TODA
Take-Off Distance Available = TORA + Clearway
ASDA
Accelerate – Stop Distance Available = TORA + Stopway
Dutch Roll
Dutch roll is a series of out of phase turns, when the aircraft rolls in one direction and yaws in the other. yaw lags roll, a dynamically stable situation. Yaw damper prevents this motion
MCrit
the lowest mach number where the airflow somewhere over the aircraft reaches the speed of sound, M1.0
Vref Categories
Aircraf categories shall be based on the IAS at threshold (Vat) which is equal to the stall speed in landing configuration (Vso) x 1.3 or Vs1g x 1.23 in the landing configuration at the maximum certified landing mass. If both Vso and Vs1g are available, the higher resulting Vat shall be used.

Time of useful conciseness at 33000’
Moderate activity 30 sec
Upslope runway gives the pilot what false indication?
Thinking he is to high on profile

How do slotted flaps work?
By re-energizing the boundary layer. High pressure air flows through the slot into the upper surface which adds energy to the boundary layer, delays airflow separation and produces less drag.
What prevents dutch roll?
Yaw Damper
Proper course of action during severe turbulence?
Set turbulence penetration speed
Secure cabin, fasten belts on
Crosswind from the right, what happens to the plane and how to correct.
Nose into the wind to maintain track
How does most dissolve?
- Wind
- Higher temperatures/ when air heats up
Effect of de-icing on the ground?
Using more fuel
When can you descend on a NDB approach?
When you are within 5 degrees of the final approach track.
What do you do when fuel is under company policy/final reserve?
Declare an emergency
Ice build up up and under the wing, what to expect?
Later lift off and higher lift off speed needed because of airflow interruption over the wings, more drag and stall speed increases
Wet runway, how do we get correct?
Using rudder up to max deflection
CB cloud/ microburst
- up and downdrafts
- windshear
Quality’s of a swept wing?
- increases MCrit
- Reduced drag
- less prone to turbulence
- tips stalls First causing nose up movement
- increases positive lateral and directional stability
TAF?
Terminal Aerodrome Forecast
Position report over the Atlantic, what to report and when?
When:
- Every waypoint
- Or 45 min since your last report, whichever is earlier
- whenever you wish to change speed or altitude
- if ETA for inbound waypoint differs +/- 3 min from previous reported times
What:
- Aircraft Ident
- FL or Altitude
- Next waypoint and ETA of Next waypoint
- Waypoint after next waypoint

Why do we use SOP’s?
To provide guidelines for crew to operate together as a coordinated team.
What is Mach tuck and how do you counter it?
It is a nose down tendency created by a change in the position of the centre of pressure resulting from a rearword movement of the shockwave which occurs as an aircraft accelerates beyond its limiting machnumber.
- Counter it using Mach trim
- Don’t fly above MMO
- Vortex Generators
Fuel planning?
- Taxi fuel
- Trip fuel
- Reserve (final reserve, contingency)
- Alternate fuel
- Extra fuel
What is the danger of decompression at high altitude?
Lack of oxygen causing hypoxia, decreasing performance of pilots and crew, could result in loss of life
How does a INS/IRS work?
An INS/IRS use the main starting point and the system derives attitude, velocity and directional information from measuring the aircrafts accelerations using gyro’s. It makes calculations based on the forces made by acceleration to determine the aircraft ms location.
Why fuel in kilograms and not in liters?
To correct for temperature, weight (mass) does not with temperature but volume does.
Memory items engine fire

Memory items Rapid decompression
Done
Draw a jet Engine
Intake: steady flow of air
Compressor: Compresses the air
Combustion: Burns fuel with compressed air causing it to expand
Turbine: Extracts energy from exhaust gasses to drive compressor and Fan
