Why do we calculate mass and balance?
Why do we calculate mass and balance?
To be within aircraft design limitations with regards to:
Structural limitations
Stability
Take-off and landing performance
How does a stall strip work?
How does a stall strip work?
A stall strip, usually located close to the wing root, causes the airflow to separate at a lower angle of attack and ensures that the wing root stalls before the wing tips.
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.
Why does a wing stall?
Why does a wing stall?
A wing stalls because the airflow over the wing’s upper surface separates when the critical angle of attack is reached or exceeded. This causes a reduction in the lift generated by the aerofoil
What is Vs?
What is Vs?
Stall speed is defined as the minimum steady flight speed at which the airplane is controllable.
Do airplanes have an optimum C.G.? If yes, where is it?
Do airplanes have an optimum C.G.? If yes, where is it?
Yes, the closer the C.G. is to the rear limit, the less tail down force is required, which means less drag which results in less fuel burn.
What is a Great Circle?
What is a Great Circle?
A line of shortest distance between two points on a sphere.
What is a METAR?
What is a METAR?
A METAR is an observation of the actual weather given by a meteorological observer at that aerodrome.
Why do the fuel gauges read in kg, but fuel is delivered in litres?
Why do the fuel gauges read in kg, but fuel is delivered in litres?
Because the specific gravity can change with temperature.
How does an airspeed indicator work and which errors can an airspeed indicator experience?
How does an airspeed indicator work and which errors can an airspeed indicator experience?
The airspeed indicator uses part of the aircraft's pitot-static system to measure and compare the dynamic air pressure between air moving into the pitot tube and static air pressure measured in the case.
The ASI is calibrated to ISA at MSL and represents the dynamic pressure as indicated airspeed in knots per hour.
ASI errors can originate and vary from:
