and Special Traffic Management Programs
This section describes procedures for obtaining
required airport reservations at airports designated by
the FAA and for airports operating under Special
Traffic Management Programs.
a. Slot Controlled Airports.
1. The FAA may adopt rules to require advance
operations for unscheduled operations at certain
airports. In addition to the information in the rules
adopted by the FAA, a listing of the airports and
relevant information will be maintained on the FAA
website listed below.
2. The FAA has established an Airport
Reservation Office (ARO) to receive and process
reservations for unscheduled flights at the slot
controlled airports. The ARO uses the Enhanced
Computer Voice Reservation System (e-CVRS) to
allocate reservations. Reservations will be available
beginning 72 hours in advance of the operation at the

maintained. Flights with declared emergencies do not
require reservations. Refer to the website or
touch-tone phone interface for the current listing of
slot controlled airports, limitations, and reservation
procedures.

and reservation procedures at a Slot Controlled
Airport, please see 14 CFR Part 93, Subpart K " High

(STMP).
1. Special procedures may be established when
a location requires special traffic handling to

The special procedures may remain in effect until the
