What is adverse yaw?
What is adverse yaw?
When rolling the aircraft the up-going wing will experience more drag than the down-going wing. This will result in a yawing moment that directly opposes the desired direction of turn. (i.e.: rolling left will cause a right yaw.)
What do you know about carb icing? Would you experience it today?
What do you know about carb icing? Would you experience it today?
Carb icing can occur in the engine induction system and in the carburettor of piston engines.
Regarding the second question, mention the conditions in which carb icing can occur and if it would be possible on that particular day.
Conditions for carb icing: when OAT is between -10 & +30, with high humidity (greater than 40%) and/or visible moisture.
What are the advantages of an all moving/variable incidence tailplane?
What are the advantages of an all moving/variable incidence tailplane?
This provides pitch manoeuvrability.
Longitudinal balancing by the trim system.
What is DOM?
What is DOM?
The Dry Operating Mass (DOM) is the Basic Empty Mass and the Variable Load, also called the Aircraft Prepared for Service (APS) weight.
Being an excellent pilot, if I can fly at VMCA, do I need a V2 speed?
Being an excellent pilot, if I can fly at VMCA, do I need a V2 speed?
Yes, for safety you will need a V2 speed.
Why is anhedral used instead on some aircraft?
Why is anhedral used instead on some aircraft?
Anhedral:
compensates for the wing sweep improves roll maneuverability
Explain the definition “critical engine”.
Explain the definition “critical engine”.
The critical engine of a multi-engine, fixed-wing propeller-driven aircraft is the one whose failure would result in the most adverse effects on the aircraft's handling and performance.
Due to the asymmetric blade effect (P-factor), the right-hand engine typically develops its resultant thrust vector at a greater lateral distance from the aircraft's C.G. than the left-hand engine.
The failure of the left-hand engine will result in a larger yaw effect via the operating right-hand engine, rather than vice-versa, and it is termed the Critical Engine. Since the operating right-hand engine produces a stronger yaw moment, the pilot will need to use larger control deflections in order to maintain aircraft control. Thus, the failure of the critical (left-hand) engine is less desirable than failure of the right-hand engine.
The operating right-hand engine will produce a more severe yaw towards the dead engine, thus making the failure of the left-hand engine critical.
Does the N1 compressor produce thrust?
Does the N1 compressor produce thrust?
Yes, with the modern high bypass turbofans the N1 compressor works as a huge propeller, it takes a big mass of air and gives it a relative small acceleration.
Around 70% of the air will bypass the core of the engine, only 30% of air will be compressed further and will eventually go through the combustion chamber.
If the yaw damper fails and the aircraft experiences Dutch roll, how can the pilot stabilize the aircraft?
If the yaw damper fails and the aircraft experiences Dutch roll, how can the pilot stabilize the aircraft?
Apply opposite aileron to the direction of the roll.
What are the effects on the human body in case of depressurisation?
What are the effects on the human body in case of depressurisation?
Hypoxia, a lack of oxygen to tissues of the body due to low partial pressure at altitude.
Symptoms are: blue lips, apparent personality change, impaired judgement, muscular impairment, short term memory loss, sensory loss, hyperventilation, unconsciousness.
Other possible effects:
-
Baurotrauma
-
Lung damage
