1.
A useful method of a pilot resolving, during a visual flight, any uncertainty in the aircraft's position is to maintain visual contact with the ground and:
a) fly reverse headings and associated timings until the point of departure is regained
b) fly expanding circles until a pinpoint is obtained
c) fly the reverse of the heading being flown prior to becoming uncertain until a pinpoint is obtained
d) set heading towards a line feature such as a coastline, motorway, river or railway
2.
Consider the following factors that determine the accuracy of a DR position. 1. The flight time since the last position update. 2. The accuracy of the forecasted wind. 3. The accuracy of the TAS. 4. The accuracy of the steered heading. Using the list which of the above statements is correct?
a) 1 and 2.
b) 1,2,3 and 4.
c) 1, 2 and 4.
d) 1, 2 and 3.
3.
The accuracy of the manually calculated DR position of an aircraft is, among other things, affected by?
a) The flight time since the last position update.
b) The accuracy of the adjustment of the position lines for the motion of the aircraft between the last fix and the DR position.
c) The accuracy of the actual wind.
d) The accuracy of the adjustment of the position lines for the motion of the aircraft between the last and the new DR position.
4.
The accuracy of the, manually calculated, DR-position of an aircraft is, among other things, affected by?
a) The accuracy of the adjustment of position lines for the motion of the aircraft between the last and the new DR position.
b) The accuracy of the forecasted wind.
c) The accuracy of the adjustment of position lines for the motion of the aircraft between the last fix the DR position.
d) The accuracy of the actual wind.

b) The accuracy of the actual wind.
c) The flight time since the last position update.
d) The accuracy of the adjustment of position lines for the motion of the aircraft between the last and the new DR position.
6.
Consider the following factors that determine the accuracy of a DR position: 1. The flight time since the last position update. 2. The accuracy of the forecasted wind. 3. The accuracy of the TAS. 4.

a) 1,2 and 3.
b) 1,2,3 and4.
c) 1 and 2.
d) 1,2 and 4.
7.
What may cause a difference between DR-position and a fix?
a) The difference between the actual wind and the forecasted wind.
b) The difference between the magnetic and true wind directions.
c) The difference between no-wind and the forecasted wind.
d) The difference between no-wind and the actual wind.
8.
The ICAO definition of ETA is the:

b) estimated time of arrival at destination
c) actual time of arrival at a point or fix
d) estimated time en route
9.
When flying on a constant great circle tracking the southern hemisphere you will?

b) Experience an increase in value of true track.
c) Fly a spiral and finally end up at the south pole.
d) Experience a decrease in value of true track.
10.
Given: . AD = Air distance GD = Ground distance TAS = True Airspeed GS = Groundspeed . Which of the following is the correct formula to calculate ground distance (GD) gone?
a) GD = (AD X GS)/TAS
b) GD = AD X (GS -TAS)/GS
c) GD = TAS/(GS X AD)
d) GD = (AD - TAS)/TAS
11.
From the departure point, the distance to the point of equal time is :
a) inversely proportional to the total distance to go
b) proportional to the sum of ground speed out and ground speed back
c) inversely proportional to the sum of ground speed out and ground speed back
d) inversely proportional to ground speed back
12.
During a low level flight 2 parallel roads that are crossed at right angles by an aircraft. The time between these roads can be used to check the aircraft:
a) track
b) position
c) drift
d) groundspeed
13.
What is the effect on the Mach number and TAS in an aircraft that is climbing with constant CAS?
