List the factors to be considered when selecting a VFR cross-country navigation route.
When planning a VFR cross-country, you must consider any diversions that may be required due to bad weather e.g. to get around high terrain if there is low cloud.
Airspace, danger, restricted, military and volcanic area considerations
The terrain you are flying over (forced landing options and civilisation in case of an emergency)

Compute TAS, given CAS, pressure altitude and air temperature in degrees Celsius.
To calculate TAS, CAS, Pressure Altitude, temperature conversions and many more, pilots use a flight computer (pictured below)

6.22.2. Define scale and the relationship between chart and earth distances
The chart scale is the the ratio of a given chart length to the actual distance on the Earth.
Eg: scale = 1 : 250,000
This means, a length on the chart of 1 unit, is 250,000 times the distance on the Earths surface.
Describe the six figure systems of indicating date/time groups
The 6 figure time system is set out with; Day, Hours and Minutes:
Hours are identified by 2-digit numbers starting at 00 and ending at 24. Minutes are expressed as starting at 00 and finishing with 59
DDHHMM
061330
Day 06 th – of the month
Hour 1300 – th hour of the day
Minutes 30 – th minute of the day
6.14.2(a) True and magnetic track required
The Track Required is the intended path to be flown to a point or destination.
The track can either be displayed as True or Magnetic; which is in relation to Magnetic North or True North.
6.12.2(a) Height;
Height is the vertical distance above a datum, such as the ground.
6.10.2(a) Ground position;
Ground position is the position of an object in relation to the Earths surface; with regards to an aircraft, this position will be directly below the aircraft.
6.8.2(a) Knot (kt);
Knots are used as a measurement of speed.
1 knot =
1 nautical mile per hour (by definition),
1.852 kilometres per hour (exactly),
1.151 miles per hour (approximately).
6.6 Distance on the Earth
6.6.2 Define:
(a) statute mile;
(b) nautical mile;
(c) kilometre;
(d) metre;
(e) foot.
6.6.4 Calculate the conversion between a statute mile, a nautical mile and a kilometre.
6.6.6 Measure distances up to 300nm (± 1%) on an appropriate chart.
6.8 Speed and Velocity
6.8.2 Define:
(a) a knot (kt);
(b) ground speed (GS);
(c) indicated airspeed (IAS);
(d) calibrated airspeed (CAS);
(e) true airspeed (TAS).
6.8.4 Explain the difference between speed and velocity.
