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.

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.
