Flight Planning and Monitoring - Aero Planes: DGCA Air Navigation questions

True course (TC) 017º, W/V 340º/30kt, True air speed (TAS) 420kt. Find: Wind correction angle (WCA) and ground speed (GS).

You are flying a constant heading of 252º. Variation is 22ºE, deviation is 3ºW and your INS is showing a drift of 9º right. The true track is?

A twin-jet aeroplane carries out the X-Y flight. When it reaches point K (35ºN, 048ºW), a non-mechanical event makes the Captain consider rerouting to one of the three following fields. The flight conditions are:

• From K to A (distance 847NM, headwind component = 18kt)
• From K to B (distance 1112NM, tailwind component = 120kt)
• From K to C (distance 883NM, wind component = 0) With an aeroplane true airspeed of 460kt, the field selected will be that more rapidly reached:

On a given path, it is possible to choose between four flight levels (FL), each associated with a mandatory flight Mach Number (M). The flight conditions, static air temperature (SAT) and headwind component (HWC) are given below: FL 370; M = 0.80; Ts = -60ºC; HWC = -15kt

How many feet you have to climb to reach FL 75? Departure aerodrome elevation = 1500 ft. QNH = 1023 hPa. Temperature = ISA. 1 hPa = 30 ft.
