CHAPTER THREE
you if the situation warrants prior to returning to his frequency. During this switch, you can
receive ATIS, give a PIREP (pilot report), talk to BASE, METRO, or a FSS facility, etc. If the
controller did put a time limit on your switch, be sure to honor the request.
When complete with whatever administrative task prompted the switch, report that you have
returned to the control frequency.
Example
SNFO/SWSO:
"Atlanta Center, KATT 821 is back up."
CENTER:
"KATT 821, Atlanta Center, roger."
310. REQUESTING ALTITUDE CHANGES
Perhaps there is turbulence at your altitude, or your pilot would prefer to fly in VMC conditions
if the current altitude is IMC. Because a change in altitude is not a long request, there is no need
for a courtesy call (nor is there a need for an explanation).
Example
SNFO/SWSO:
"Atlanta Center, KATT 150, request FL 210."
CENTER:
"KATT 150, climb and maintain FL 210."
SNFO/SWSO:
"KATT 150, leaving FL 190 for FL 210."
If already in contact with a controller who amends your altitude while you are in a climb/descent,
it is not required to again say passing or leaving the current altitude.
Example
SNFO/SWSO:
"Atlanta Center, KATT 150, passing 16,000 for
FL 210."
CENTER:
"KATT 150, climb and maintain FL 190."
SNFO/SWSO:
"KATT 150, continuing to FL 190."
After the initial request, Center may tell you to standby while they deconflict traffic. They may
say "expect higher in XX minutes (miles)". Make sure the altitude you request is proper, using
semicircular cruising rules.
If you would like to climb to a specific altitude, request this specific altitude (e.g., FL 250) as
opposed to merely saying: "Center, KATT 150 requesting higher." This latter call may only get
you up to some intermediate altitude. Don't make the controller play a guessing game. If you
want something specific, ask for it.
