The shortest distance in NM between point X(30°20'N, 020°20'E) and point Y(30°20'N, 159°40'W) is..

An aircraft is climbing from an airport at Mean Sea Level to an altitude of 21 000 ft.

Determine the wind vector which should be used to plan the climb, given:

 The reported surface wind is 030 /15 kt and it is in ISA conditions.

 The upper winds are: 

 FL 050: 050°/25 kt

 FL 100: 070°/30 kt

 FL 180: 090°/40 kt

 FL 240: 110°/50 kt

The airport chart for Halifax, Nova Scotia, Canada shows the variation is 18°W. The final approach track for the ILS to runway 23 is given as 233°. The drift on final approach is 6° right. Determine the true direction of the final approach track:

The accuracy of the, manually calculated, DR-position of an aircraft is, among other things, affected by:

Compass deviation is defined as the angle between..

The distance between A and B is 105 NM. At a distance of 15 NM from A the aircraft is 3 NM right of course. To reach destination B, the heading should be altered by...

What is the relationship between air distance and ground distance with a headwind?

What is the track error angle? Given: 

 Planned track: 252°(T) 

 Actual heading: 252°(T)

 Actual flight drift: 3° right

Determine the NAM given a NGM of 180 NM, TAS of 165 kt and GS of 150 kt:

Refer to figure. The Charter flight log is filled out correctly by the pilot of a light twin-engined aeroplane. Calculate the average Groundspeed from TOC to TORDU and the ETA at RODRA.
