Changing Altitude with Flight Following

Featuring

Subscriber question:

"Do you need to tell ATC when you change altitude if you're getting Flight Following?" — Frank W.

John:

“The short answer is yes.

Guidance is contained in the AIM (Aeronautical Information Manual) under paragraph 4-1-15 (b)(2). It states that when receiving VFR radar advisory service, pilots should inform the controller when changing VFR cruising altitude.

VFR advisories, also known as Flight Following, are a service provided by radar-equipped ATC facilities. Pilots receiving this service are advised of any radar target observed on the radar display which may be in such proximity to the position of their aircraft or its intended route of flight that it warrants their attention. The controller may issue a turn or altitude change to help the pilot avoid conflicting traffic.

The avoidance vector or altitude is based on the current or projected path of both aircraft. It makes sense that the controller must be aware of any altitude changes you plan to make.

The controller may also assign an altitude that is contrary to the normal VFR altitudes for traffic avoidance—especially in Class B or C airspace. ATC is required to advise the aircraft when to resume appropriate VFR altitudes.”

How often do you report altitude changes to ATC when receiving VFR advisories?

(NEW) VFR Mastery scenario #81 “Flight Following Failure” is now available. Flight following is the best way to get an extra set of eyes for traffic and keep in touch with ATC inside busy airspace. That’s why you planned your trip to use this valuable tool. So what’s your next move when ATC decides to cut you loose just when you need Flight Following the most? Watch the Intro video.
