7.11. VNAV COMMUNICATIONS

7.11.1. While radio communications in the low-level environment are minimal, there are some

special calls unique to preparation for low-level entry and exit.

7.11.1.1. Terminating IFR: One of the first calls specific to low-level VFR flight is cancellation

of IFR. IFR cancellation is not a request, but a statement to the controlling facility. To cancel

IFR, as a minimum, the following conditions must exist:

Aircraft must be VMC.

Aircraft must be clear of Class A airspace (Below 18000 feet)

In situations where the above conditions are not met, use the following procedures to establish

VFR conditions:

(1) Terminating IFR Within the Class "A" Airspace: If at or above FL 180, a descent below

Class "A" airspace is necessary prior to canceling IFR. The following communication
