What is the difference between a supercharger and a turbocharger?
What is the difference between a supercharger and a turbocharger?
A turbo charger is externally driven by exhaust back pressure turning a turbine which in turn drives a compressor in the induction manifold to increase the air pressure (constant volume, higher pressure) and is controlled by waste gate.
A supercharger is internally driven by the propellor shaft to compress mixture and is controlled by RPM.
What is convergency?
What is convergency?
Meridians converge from their maximum distance apart (at the equator) to the poles where they meet.
Great circles are the shortest distance between two points and convergency represents the change in direction experienced between those points.

A line of latitude.
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.

How does TCAS work?
How does TCAS work?
TCAS works by sending interrogations to other aircraft's transponders.
The transponder will reply to the interrogation in a similar way it responds to radar. From the time difference between the interrogation and the reply, the distance to the other aircraft is calculated. The reply itself contains the altitude of the other aircraft.
The distance and the altitude difference with the other aircraft is tracked to identify a trend which may result in a TA or eventually a RA.
Some wings, flaps and rudders are indented, why?
Some wings, flaps and rudders are indented, why?
To increase the strength of the surfaces.
The same strategy is employed by plastic water bottles, by adding ridges to a surface you increase it's structural rigidity
What is the washout on a wing?
What is the washout on a wing?
A wing design feature where the angle of incidence of the wing decreases from the root to the tip.
This makes it so that the wing as a tendency to stall at the root first, maintaining aileron control for a longer time and providing a resistence to spinning, facilitating recovery.
