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.
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.
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 are the problems associated with icing?
What are the problems associated with icing?
Drag penalties (additional weight)
Less controllability
How does the all moving stabilator work on the Boeing 737 compared a fixed horizontal stabilizer of, for example, the Seneca?
How does the all moving stabilator work on the Boeing 737 compared a fixed horizontal stabilizer of, for example, the Seneca?
A moving stabilator allows for wider operating range of the control surface, which is of great importance in aircraft with a large range of operating speeds.
Compared to a fixed horizontal stabilizer, when trimmed, the moving stabilitor will produce less drag, reducing fuel consumption.
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:

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.
If you are flying your light twin, how would you ensure minimum obstacle clearance if your engine fails on take off? How would you do this, or, where can you find the relevant information?
If you are flying your light twin, how would you ensure minimum obstacle clearance if your engine fails on take off? How would you do this, or, where can you find the relevant information?
In the airplane documents, as the airplane is certificated regarding performance to be able to fly blue line speed (or Vyse) in this situation, so I would climb at this speed to ensure minimum obstacle clearance.
What frequency range and band is an NDB in?
What frequency range and band is an NDB in?
Frequency range from 200-1750kHz, medium and low range frequency bands.
What is the critical angle of attack?
What is the critical angle of attack?
The angle between the chordline and the incoming airflow.
