What is Dutch roll?
What is Dutch roll?
Dutch roll is an aircraft stability issue involving oscillations of rolling and yawing motions. It occurs when the aircraft's nose deviates from its path, causing rolling in the opposite direction due to the vertical fin's side force. This generates a yawing moment, resulting in a cycle of yawing and rolling motions. Dutch roll can be problematic for passenger comfort and pilot control. Measures like tail fin design, yaw dampers, and control inputs are used to counteract it and maintain stability.
What would you do in the event of an engine failure below V1, and what would your initial actions be?
What would you do in the event of an engine failure below V1, and what would your initial actions be?
Assuming I'm performing single pilot operations:
-
power idle,
-
max brakes (and reversers if available),
-maintain directional control using rudder input,
-
After coming to a full stop set parking break.
-
Inform ATC 'Stopping'.
-
Initiate the appropriate process to diagnose the problem (ECAM, NITS DODAR, checklists....).
-
When performing multi pilot operations the actions performed by me will depend with my current role: PF, PM and/or CM1 CM2.

What does a bypass ratio of 11:1 mean?
What does a bypass ratio of 11:1 mean?
For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.
While climbing with a SEP, in what temperature range can carb icing occur?
While climbing with a SEP, in what temperature range can carb icing occur?
Carb icing can occur with temperatures as high 30°C and humidity as low as 50%, but it is more likely when below 20°C and high humidity, especially during low power settings.
Describe the take off segments.
Describe the take off segments.
1st segment starts at screen height and finishes at gear retracted.
2nd segment starts when the gear is retracted and finishes when acceleration alt is reached (min. 400ft max 1000ft) speed V2.
3rd segment starts at acceleration alt, minimum 400ft, and finishes when the flaps are retracted.
4th segment starts when the flaps are retracted, MCT is set and finishes at the 1500ft.
Can a helicopter rotor blade stall?
Can a helicopter rotor blade stall?
Yes
What is the effect of weight on the glide range?
What is the effect of weight on the glide range?
The glide range is not affected by the weight. Howver Vmd is. The heavier the aircraft, the higher the Vmd.
Describe the lift-weight pitching moments.
Describe the lift-weight pitching moments.
The weight of an aircraft is applied at the CG. The lift at the CP. The relative position between these 2 points determines the stability of the aircraft. For an Aircraft with a tail surface, a CG in front of the CP constitutes a stable system, while a CG behind the CP an unstable system.
