What is a Rhumb Line?
What is a Rhumb Line?
A line across the surface of the earth that cuts all meridians at the same angle. i.e. a track of constant direction.
A straight line on a Mercator chart.
What performance category was your last aircraft? How are airplanes classified?
What performance category was your last aircraft? How are airplanes classified?
Note: this question was asked to a candidate with previous Seneca experience, make sure to be able to answer this question for your previous aircraft type.
Seneca is class A.
Aircraft are classified according to their Vat.
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.
What is anhedral?
What is anhedral?
anhedral is the downward inclinitation of the wing from the root to the tip.
What is the effect of weight on rate of descent?
What is the effect of weight on rate of descent?
To be the most efficient, aircraft descend at Vmd. Vmd increases with Weight, and therefore the rate of descent increases as well with weight.
What is the critical point?
What is the critical point?
The critical point (CP) is a point on a track where it is as quick to go on as it is to turn back.
Also known as ETP (Equal Time Point) and PET (Point of Equal Time).
Describe aspect ratio.
Describe aspect ratio.
The ratio between the wing span and the mean chord line.
A high aspect ratio is associated with good lift to drag ratio, i.e.: Gliders.
A low aspect ratio is usually associated with fast aircraft, i.e.: Fighter jets.
When does speed change from IAS to Mach?
When does speed change from IAS to Mach?
At FL260
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.
