AIRPLANE FLIGHT MANUAL
To: All Gulfstream IV Operators
Subject: GIV AFM Revision 30 dated 11 October 2002
This revision has two main purposes. The first is to incorporate a new emergency procedure, Fuel
Leak In Flight. This procedure will help pilots determine the location of the fuel leak and take the
appropriate actions to stop the loss of fuel or lessen the severity by moving the fuel out of the
system with the leak.
The second is to revise both GIV-SP and Non-SP Appendix E, Adverse Weather/Abnormal
Atmospheric Conditions holdover tables for deicing fluids. These tables were updated to reflect
the latest guidance from the FAA regarding cold weather operations and operation in icing
conditions.
The remainder of the revision contains minor changes and cleanup as a result of input from the
training providers and GIV operators.
If there are any questions regarding the technical content of this revision or additional corrections
or input of items that are needed in the AFM, please contact Bruce Barefoot at (912) 963-6367
(bruce.barefoot@gulfaero.com) or Kathy Rudd (912) 965-7606 (kathy.rudd@gulfaero.com). For

AIRPLANE FLIGHT MANUAL
To: All Gulfstream IV Operators
Subject: GIV AFM Revision 29 dated 30 May 2002
This revision has three main purposes. The first is to add the new FMS software level NZ6.X and
the Honeywell Publication Number for the software. The second is to add the procedure for Use
of the Rudder In Flight. This procedure is being added as our response to the NTSB
recommendation, and the FAA letter requesting OEM’s to add this information to the AFM. The
third concerns the inclusion of removing cabin and galley electrical power as a probable source
for cabin fire/smoke.
Several aircraft performance changes have been included in this revision. There are several new
Maximum Allowable Takeoff Gross Weight Permitted By Takeoff Climb Requirements charts as
a result of now being able to use Takeoff Thrust for 10 minutes for single engine operations.
(The old limit was 5 minutes.) This change also impacts the Distant Obstacle Clearance charts
and the Reduced Thrust (Flex) Takeoff tables in the AFM appendix. The Performance Computer
will still calculate takeoff data based on the original five minutes at takeoff power. Gulfstream
will update the Performance Computer for the new ten minute takeoff performance sometime in
the future. Until then, to take advantage of the new capability, crews will have to do manual
calculations. Finally, we have included 2 new charts that enable operators to determine
acceleration distance from V2 to VSE at 1500 feet AGL (Above Ground Level). The inclusion
of these latter charts will now enable operators to compute obstacle clearance when obstacle
heights are greater than 1500 feet AGL. (The FAA only requires the AFM to determine obstacle
clearance when obstacle heights are less than 1500 feet AGL.)
The remainder of the revision contains minor changes and cleanup as a result of input from the
training providers and GIV operators.
If there are any questions regarding the technical content of this revision or additional corrections
or input of items that are needed in the AFM, please contact Bruce Barefoot at (912) 963-6367

AIRPLANE FLIGHT MANUAL
To: All Gulfstream IV Operators
Subject: GIV AFM Revision 28, dated 29 January 2002
This revision has two main purposes. The first is to add the reference to the CD 820 and the
associated pilot’s manual in the Limitations section. The second is to update references to
RNP0.3 approaches in the Limitations section and to modify the RNAV procedures in the
Normal Procedures section. The RNP0.3 approaches are now coded as also being GPS
approaches. The requirement to monitor the GPS navigation mode or to delete DME/DME
updating for these approaches is no longer required. The FMS will advise the crew via the
DEGRADE light if the proper navigation mode is no longer available during the approach.
