What would look like if we use it in IF?
Tower: N757MX, Runway 18C, Cleared for (immediate) takeoff. After depature, contact Radar on 135.29
N757MX: Cleared for Takeoff, Runway 18C, and contacting Radar on 135.29 after depature, N757MX
If you are a ATC controlling a very busy overloaded class Bravo airport, and you want to reduce your workload very quickly, you can use this command to make sure that the departing traffic contacts Radar after they take-off, without the danger that you forget about the aircraft, which makes more stress. Also, you let the pilots know the Frequency change on the Takeoff clearence, so they donât have to request it and switch to Radar.
Feel free to vote it :)
Is always appreciated
Edit: If you donât know what is it, you have to search a lot :)
