Where does the wing stall first on a typical SEP Aircraft (Cessna, Tecnam, ...)?
Where does the wing stall first on a typical SEP Aircraft (Cessna, Tecnam, ...)?
At the wing root. This is a property of rectangular wings, but it's also common to find close to the wing root devices that make it so that the wing root stalls first.
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.
What is the range of a VOR at 32000ft?
What is the range of a VOR at 32000ft?
Range = 1.23(√H1 + √H2)
= 1.23 * √32000
= 220 nm
How accurate are NDB's?
How accurate are NDB's?
NDB’s are stations emitting a signal. There is nothing for them to be accurate about. ADF's on the other hand, when tuned to an NDB need to be accurate within +/- 5 degrees.
What do you prefer, a high or low wingload?
What do you prefer, a high or low wingload?
The assessor was trying to get to the approach where you need flaps and slats to increase S (lower wingload) in order to be able to fly a lower speed.
How much thrust comes from the N1 fan?
How much thrust comes from the N1 fan?
Depends on the engine.
In the case of the 737-800 CFM56, 27,300lbs total thrust at a ratio of 5.5:1
When does speed change from IAS to Mach?
When does speed change from IAS to Mach?
At FL260
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.
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.
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.
