Coordinated Time (UTC), or “Z” time. This “Z” time is determined by using either local Standard Time or
local Daylight Saving Time. Daylight Saving Time is in effect from 0200 local time the first Sunday in April
to 0200 local time the last Sunday in October.

earlier during periods of Daylight Saving Time.
Airport Restrictions - Among other things, airport restrictions may include:
1. Prior Permission Required (PPR): To use this airport, you must call Base Operations on the
autovon number listed, give your ETA, type of aircraft, name, and business to obtain a PPR
number. In the “REMARKS” section of your flight plan (DD-175), enter the airport location identifier
and the PPR number assigned to your aircraft. Without other restrictions, a PPR airport can be
used as a fuel stop if you obtain a PPR number.
2. Official Business Only (OFFL BUS ONLY): This airport is closed to all military transient aircraft
and cannot be used as a fuel stop. You must be going to the airport specifically to contact a
person or group of persons on official government business. A cross-country flight requiring a fuel
stop is not official business.
USAF personnel require written orders to use these airports; however, Navy personnel do not.
