You are VDF equipped in the tower. A pilot req a QDR. What is the pilot asking?
The magnetic track from the VDF station to the aircraft (Krudt i røv)

1030 mhz
A SSR receives on what frq?
1090 mhz
If the frq decrease, the wave lengths will..
Increase

Over a congested area less than 1000’ above highest obstacle
In airspace class D, what do you separate as air traffic control?
IFR to IFR only
IFR flight heading west shall cruise at
