To work out your speed you need to know first ….

1. Distance travelled.

2. Time taken.

In this example we have to calculate the speed of our aircraft across the ground, Lets say we have flown 34 nm in 14 minutes.

On the Wizz wheel, Distance is on the out side and time is on the inside.

1. Distance of 34 on the outside 

2. Time on the inside of 14 mins.

Now we have Distance and Time Ratio setup.

3. Find the time of 60 / Hour on the inside (as time is on the inside).

4. Read off the speed of 146 the on outside. This is distance in an hour,thus your speed is 146 knots

6.14.2(i)  Track Made Good; 

Track Made Good (TMG) is the actual track or path the aircraft flies over the surface of the Earth. 

6.12.2(i)  QNH. 

QNH refers to the current mean sea level pressure for the given day. 

When QNH is set, the altimeter will read altitude (above sea level) 

You can also set the altimeter subscale setting to QNH to obtain elevation when on the ground.

6.6.6. Measure distances up to 300nm (1%) on an appropriate chart

To measure distance on a chart, first you must use an appropriate ruler with the appropriate scale. 

Then accurately measure (1% error margin) from the starting point of the route to the finishing point, reading off the length of the track or route against the scale on the ruler. 

Describe the procedures and techniques to safely manage the fuel for a given flight.

Most flight plans have a column for fuel consumption rate and a column for fuel used per segment. 

Allowances made for reserves which should be no less than 30 minutes for aeroplanes during the day and 45 minutes at night. 

To determine fuel consumption for each leg of a flight, you have to first know the fuel burn per hour, as well as the EET for each leg. This will give you the amount of fuel needed to fly the amount of time taken for the particular leg.
