Distress and Urgency Procedures

(4) If unable to provide this information,

use code words and/or transponder as follows:

Spoken Words

TRANSPONDER SEVEN FIVE ZERO ZERO
Meaning

I am being hijacked/forced to a new destination
Transponder Setting

Mode 3/A, Code 7500

NOTE−

Code 7500 will never be assigned by ATC without prior

notification from the pilot that the aircraft is being

subjected to unlawful interference. The pilot should refuse

the assignment of Code 7500 in any other situation and

inform the controller accordingly. Code 7500 will trigger

the special emergency indicator in all radar ATC facilities.

c. Air traffic controllers will acknowledge and

confirm receipt of transponder Code 7500 by asking

the pilot to verify it. If the aircraft is not being

subjected to unlawful interference, the pilot should

respond to the query by broadcasting in the clear that

the aircraft is not being subjected to unlawful

interference. Upon receipt of this information, the

controller will request the pilot to verify the code

selection depicted in the code selector windows in the

transponder control panel and change the code to the

appropriate setting. If the pilot replies in the

affirmative or does not reply, the controller will not

ask further questions but will flight follow, respond to

pilot requests and notify appropriate authorities.

d. If it is possible to do so without jeopardizing the

safety of the flight, the pilot of a hijacked passenger

aircraft, after departing from the cleared routing over

which the aircraft was operating, will attempt to do

one or more of the following things, insofar as

circumstances may permit:

1. Maintain a true airspeed of no more than

400 knots, and preferably an altitude of between

10,000 and 25,000 feet.

2. Fly a course toward the destination which the

hijacker has announced.

e. If these procedures result in either radio contact

or air intercept, the pilot will attempt to comply with

any instructions received which may direct the

aircraft to an appropriate landing field or alter the

aircraft’s flight path off its current course, away from

protected airspace.

6−3−5. Fuel Dumping

a. Should it become necessary to dump fuel, the

pilot should immediately advise ATC. Upon receipt

of information that an aircraft will dump fuel, ATC

will broadcast or cause to be broadcast immediately

and every 3 minutes thereafter the following on

appropriate ATC and FSS radio frequencies:

EXAMPLE−

Attention all aircraft − fuel dumping in progress over −

(location) at (altitude) by (type aircraft) (flight direction).

b. Upon receipt of such a broadcast, pilots of

aircraft affected, which are not on IFR flight plans or

special VFR clearances, should clear the area

specified in the advisory. Aircraft on IFR flight plans

or special VFR clearances will be provided specific

separation by ATC. At the termination of the fuel

dumping operation, pilots should advise ATC. Upon

receipt of such information, ATC will issue, on the

appropriate frequencies, the following:

EXAMPLE−

ATTENTION ALL AIRCRAFT − FUEL DUMPING BY −

(type aircraft) − TERMINATED.
