This screen shows the Combined Clearance Menu of the London Control simulation
It allows clearances such as climbs and descents, as well as navigation clearances
and speed restrictions, to be input.
A climb clearance to Flight Level 310 is being input for flight ABD554, on
track direct to Berry Head.
In the top-left corner, the Vertical Assistance Window can be seen. This shows
potential conflicts with other flights that might affect the clearance being
given to the selected aircraft.
