What is the mean chord line?
What is the mean chord line?
It's the wing area divided by the wing span.
What is the coefficient of Lift?
What is the coefficient of Lift?
An adymensional number relating the lift with the dynamic pressure of the incoming flow. It is dependent on the form of the object and the angle of attack.
Tell me, I was looking out the window and I saw white strokes coming out of the engines at cruising level, but I didn’t see it from an aircraft taking off, why is that and what is the difference?

Those are contrails.
The jet engine exhaust gases consist of carbon dioxide and water vapour.
At high altitudes the wator vapour gets released in a very cold environment. This can cause the air to be saturated with water vapour and then condenses. If cold enough the condense can freeze into white droplets. This forms the contrails.
Why do we calculate mass and balance?
Why do we calculate mass and balance?
To be within aircraft design limitations with regards to:
Structural limitations
Stability
Take-off and landing performance
Where do Jeppesen get the information from to make their charts and plates?
Where do Jeppesen get the information from to make their charts and plates?
Government sources.
What is a Great Circle?
What is a Great Circle?
A line of shortest distance between two points on a sphere.
What do you need to descend from MDA on a non-precision approach?
What do you need to descend from MDA on a non-precision approach?
You will need to have a clearance, to be stable and visual.
What is profile drag?
What is profile drag?
Profile drag, also known as pressure drag or form drag, is the drag caused by the separation of the boundary layer from a surface and the wake created by that separation.
It is primarily dependent upon the shape of the object and increases directly with speed as the faster an aircraft moves the more air molecules collide with it.
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.
