How would you navigate if all VOR's and NDB's en route fail?
How would you navigate if all VOR's and NDB's en route fail?
With the IRS/INS/GPS or visually.
What is a jet stream?
What is a jet stream?
Jet streams are narrow bands of high-speed upper thermal winds at very high altitudes.
What are the G-limits of the Boeing 737-800?
What are the G-limits of the Boeing 737-800?
+2.5G / -1.0G
How are contrails formed?
How are contrails formed?
Their formation is most often triggered by freezing water vapour from the exhaust of aircraft engines.
What are the problems associated with icing?
What are the problems associated with icing?
Drag penalties (additional weight)
Less controllability
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 the mean chord line?
What is the mean chord line?
It's the wing area divided by the wing span.
How would you explain to your neighbour what the difference is between a precision and a non-precision approach?
How would you explain to your neighbour what the difference is between a precision and a non-precision approach?
A precision approach uses both lateral (from left to right) and vertical guidance. A non-precision approach only uses lateral guidance.
What is the fuel capacity of the Boeing 737–800?
What is the fuel capacity of the Boeing 737–800?
20.020 litres (twenty thousand and twenty litres), about 15 tons.
Why do we measure speed as a Mach number?
Why do we measure speed as a Mach number?
Mach number describes the speed of sound, which changes with the density of the medium it is travelling through.
When you reach the speed of sound, the compressibility effect creates a supersonic flow along the wing if you exceed a certain mach number.
This causes airflow separation and flutter.
It is therefore much safer and much easier to use a Mach number to express a limit at which compressibility effects start to tear the aircraft apart, as it is a constant value at all altitudes.
