Gulfstream IVSP

Gulfstream IVSP

These changes were implemented in serial numbers 1214 and beyond. Now, here comes for the neat part. Since Gulfstream engineers had done such a good job on the regular GIV, the modification implemented with the SP are available to be carried out with the earlier GIVs.

Adding 1,400 pounds of takeoff weight, the GIV-SP can carry that many more people and or bags to your destination, all with the confidence and security of the knowing Gulfstream has made it right. Also, the ability to land with 7,500 pounds more weight opens up more airports that might make the mission do-able on that particular trip, instead of having to land somewhere else for fuel. The option to tanker that much more fuel adds to the flexibility of the GIV-SP.

Gulfstream IVSP

Several differences make the GIV-SP different from the GIV. Firstly the brake by wire system employed on the GIV was replaced with a hydro-mechanical system that improved dispatch reliability and added stronger brakes in the mix. More robust wheels and tires add to the confidence inspiring nature of the GIV-SP. Improved damping in the landing gear system itself kept the butter-smooth landings, when the increased landing weight was tacked on to the aircraft. Upgraded avionics were part of the package later in life with the GIV-SP as well, the Honeywell SPZ-8400 system replaced the 8000 version that added reliability as well. As always, the GIV-SP is another shining example of how Gulfstream gets it done.
