(editable).
2. Move the trackball left or right to set the required speed.

Turn Radius
The turn radius figure is generated from the manoeuvre speed and the rate
of turn and is therefore not editable.
Delay Countdown
To set up the manoeuvre delay countdown tick the Timer check box, the
time value previously entered in the Time to Turn field starts to count down
to zero in real time, whether or not Manoeuvre On is enabled.

Display warning is displayed.
When the delay countdown reaches zero the Timer check box is
automatically unticked.
Displaying the Trial Manoeuvre

The manoeuvre speed, course, rate of turn, time to turn, vector type and
length can be changed at any time during the trial.
