Air Navigation Practice Exam 1

One Degree of latitude is equal to:

• 60nms

• 360nms

• 60km

• 1/10,000 part of the distance from the North Pole to the Equator

A single line, drawn on paper, representing speed and direction, is known as:

• A vector triangle

• A vector

• A velocity

• A vertical

The track drawn on a map, between the departure airfield and the destination is known as:

• Track required

• Track made good

• Revised track

• Heading required

Oslo Airport (Norway) is due north of Braunschweig airfield, near Hannover (Germany). If their latitudes are 59 53N and 52 20N respectively, How far are they apart?

• 454 nms

• 554 nms

• 445 nms

• 453 nms

How fast must an aircraft fly to cover 1200nm in 3 hours:

• 400 kts

• 3600 kts

• 800 kts

• 400mph

What time is used as standard in military and commercial aviation:

• The time of the country over which the aircraft is flying.

• European daylight saving time.

• British summer time.

• Greenwich mean time. (Universal time)

The Air Triangle of velocities can be used to calculate flight data. There are 6 elements in total. How many elements are needed to calculate those missing:

• 6

• 5

• 4

• 2

An aircraft flies a track made good, 3 degrees in error from the required track. Using the 1 in 60 rule, how many miles will the aircraft be off track after 60 miles of flying:

• 2 nms

• 3 nms

• 6 nms

• 1 nms

You fly between 2 features on the ground, and note that it takes 3 minutes. If the features are 18nm apart, what is your groundspeed:

• 280 kts

• 54 kts

• 180 kts

• 320 kts

Aircrew are always aware of their Estimated Time of Arrival (ETA). Why is this?

• ETA is important for fuel calculations and air traffic control purposes.

• It is the easiest calculation to do.

• Fuel flow rate depends on ETA

• A revised ETA tells them that the wind has changed
