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 drag?
What is drag?
Drag is the component of the total aerodynamic force parallel to the relative airflow.
Drag is generated by any body placed in a flow and it's composed of friction, form, and pressure drag.
What angle of sweep do our aircraft have?
What angle of sweep do our aircraft have?
25°
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.
Why do some airplanes have dihedral wings?
Why do some airplanes have dihedral wings?
Dihedral provides:
Lateral stability (during a roll) Wing clearance, wingtip to ground has more space
If you take off on a two engine airplane with no engine failure and are below VMCA, will you have directional control?
If you take off on a two engine airplane with no engine failure and are below VMCA, will you have directional control?
Yes, some directional control as we still have two functioning engines.
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 EGPWS?
What is EGPWS?
Enhanced Ground Proximity Warning System, provides a greater level of detection than GPWS.
EGPWS is capable of ‘looking ahead’ to identify potential risks on the aircraft flight path as it includes a terrain and obstacle database.
What can you tell about occluded fronts?
What can you tell about occluded fronts?
Occluded fronts are formed during the process of cyclogenesis when a cold front overtakes a warm front. When this occurs, the warm air is separated (occluded) from the cyclone center at the Earth's surface.
Occluded fronts usually form around mature low pressure areas.
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.
