b. Issue a wake turbulence advisory to any aircraft that may be affected by wake turbulence.

ISSUE BIRD ACTIVITY ADVISORIES
a. Issue bird activity advisories if the information is derived from a pilot report, tower
observation, radar observation verified by a pilot, or a combination of these. Include in these advisories
the position; species or size of birds, if known; course of flight; and altitude.
b. Issue such advisories for at least 15 minutes after receipt of the information from pilots or
adjacent facilities. Issue these advisories unless visual observation or later reports reveal the activity is
no longer a factor.
c. Relay bird activity information to adjacent facilities anytime it appears it will become a
factor in their areas.

ISSUE PARACHUTE JUMP ADVISORIES
a. Coordinate any pertinent information with other affected ATC facilities. Coordinate this
information before and at the end of each parachute jump or series of jumps that begin or end in your
area of jurisdiction.
b. There are two ways to handle requests to conduct jump operations in or into a control zone in
which there is a functioning tower operated by the United States. You should authorize parachute
jumping regarding known or observed traffic. You also should issue advisory information to the jump
aircraft and nonparticipating aircraft as necessary for the safe conduct of the jump operation.
c. Handle notifications to conduct jump operations in other controlled airspace as follows:
(1) Issue a traffic advisory to the jump aircraft before the jump. Include aircraft type,
altitude, and direction of flight of all known traffic that will transit the airspace within which the jump
will be conducted.
NOTE: Federal Aviation Regulations require that, unless otherwise authorized by ATC, the pilot of
the jump aircraft set up radio communications with the proper ATC facility at least five minutes before
the execution of the jump for receiving traffic advisories. The jump cannot be made until such
advisories are received.
