Rocky Mountain Metro Tower Letter to Airmen: LTA-BJC-10

Subject: BJC Ground Control Sequencing

Cancellation: 09/30/2027 1200 (UTC)

Due to increased Local Control (118.6) frequency congestion, BJC Tower has adopted Standard Operating Procedures for Ground Control (GC) to sequence all aircraft to the line.

After initial call to GC, pilots can expect to be given a runway assignment and taxied to the designated run-up area using the following phraseology:

“N1234 (Runway Assignment) (Taxi Route) Advise Run-Up Complete.”

After advising GC that the run-up is complete, pilots can expect to be sequenced into line and told to monitor Tower.

Any pilot not requesting a run-up, should expect sequencing instructions from GC and should remain on GC frequency until advised.

It is helpful if pilots state the following on initial call:

Callsign, location, ATIS Code, and Intentions.

EXAMPLE: “Metro Tower, N1234 at R4 with Juliet requesting North Departure. Run-up required”

After completing the run-up, advise GC “run-up complete.” GC will then taxi you into line and instruct you to monitor Tower.
