Correct Answer is:Expediting and separating air trafficExplanation:ATC Clearances are solely issued to expedite the arrival and departures of the aircraft and to maintain separation from each other.Q17. Above FL 290 the vertical flight separation between aircraft on the same direction is:
Correct Answer is:4000 ftExplanation:Above FL290 where the density decreases so does the instrument accuracy decreases so for safety reasons the vertical separation has been increased to 4000 ft for the aircrfat flying in same direction and in opposite direction it is 2000 ft in Conventional airspace.Q18. A “RNAV” distance based separation minimum may be used at the time the level is crossed, provided that each aircraft reports its distance to or from the same “on track” way-point., This minimum is:
