You are flying at FL350 and the temperature reads -30°C, is the aircraft at its optimum temperature?
You are flying at FL350 and the temperature reads -30°C, is the aircraft at its optimum temperature?
No because it is warmer, according to ISA temperature should be -55°C

What is BEM?
What is BEM?
Basic Empty Mass (BEM) is the mass of the aircraft with the basic equipment, unconsumable fluids and unusable fuel and oil.
What does a bypass ratio of 11:1 mean?
What does a bypass ratio of 11:1 mean?
For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.
Why do we use Jeppesen charts/plates?
Why do we use Jeppesen charts/plates?
Jeppesen charts and plates are simplified and uniform.

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.
What will happen if the primer of your engine/fuel system kept operating?
What will happen if the primer of your engine/fuel system kept operating?
A variable pitch propeller provides an optimum angle of attack for the propeller blades for a longer range which reduces fuel usage, fixed pitch propellers only have a certain rpm.
Name the different aircraft categories, speeds and on which speed these categories are based.
Name the different aircraft categories, speeds and on which speed these categories are based.
Aircraft categories are based on Vat (in knots):
A <91
B 91-120
C 121-140
D 141-165
E 166 - 210
