What is the center of pressure?
What is the center of pressure?
An aerofoil when placed in a flow will (normally) cause said flow to accelerate over the aerofoil and decelerate below it.
This will cause a pressure differential between the upper and lower surface of the aerofoil, and the resultant force will be applied at the center of pressure.
What is the movement of the center of pressure during/approaching a stall?
What is the movement of the center of pressure during/approaching a stall?
Center of pressure moves forward when approaching a stall.
What are the problems associated with icing?
What are the problems associated with icing?
Drag penalties (additional weight)
Less controllability
Because usually the heated air bypasses the air filter, therefore it is possible for dust to enter the engine and so exposing the engine to unnecessary engine wear.
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
The speed is too low for an indication.
What is lift?
What is lift?
Lift is the component of the total aerodynamic force perpendicular to the relative airflow.
Lift is generated when a streamlined body, such as an aerofoil, is placed in a flow of air.
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
When does speed change from IAS to Mach?
When does speed change from IAS to Mach?
At FL260
What is rate of climb/descent?
What is rate of climb/descent?
It's vertical velocity of the aircraft usually expressed in feet per minute.
