308. FREQUENCY SWITCHES

After calling Tower for takeoff clearance, the controllers will instruct when to switch to the next

frequency. Never switch a frequency unless instructed to by a controller. Switching frequencies

need not be anticipated.

Example

CENTER:

"KATT 814, contact Memphis Center on 284.7."

SNFO/SWSO:

"KATT 814, switching 284.7."

SNFO/SWSO:

(after switching):"Memphis Center, KATT 814,

9000."

CENTER:

"KATT 814, Memphis Center, roger."

If in a climb or descent during the frequency switch, the agency will use the check-in altitude to

verify Mode C altitude. The term "passing" is appropriate.

Example

SNFO/SWSO:

"Houston Center, KATT 814, passing 6300 for

9000."

CENTER:

"KATT 814, Memphis Center, roger."
