Gulfstream Aerospace G550 Model Guide
Gulfstream Aerospace G550 · Model Guide
Overview
The Gulfstream Aerospace G550 is a large jet, listed in the registry under the Gulfstream 1159 family (G-IV, GV and GV-SP variants). The only airplane-specific documents supplied are an FAA-approved flight manual supplement on APU limits and the hydraulic systems chapter of the operating manual. No G550 price, payload or performance figures were supplied.
- The family is listed at up to 6500 nm range and up to 51000 ft service ceiling; these are family maxima, not G550 figures.
- The G550 has independent left and right hydraulic systems, and the left system has several backup pressure sources.
- A flight manual supplement restricts APU use on GV-SP (G550/G500) airplanes with improperly applied APU enclosure sealant.
- Check the airframe for the APU sealant issue and the hydraulic fluid type and servicing history before buying.

What range does the Gulfstream Aerospace G550 have?
The inputs give no range for the Gulfstream Aerospace G550 itself. The wider Gulfstream 1159 family is listed at up to 6500 nm, up to 459 kt cruise and up to 51000 ft service ceiling. These are family maxima, so confirm G550 figures in its flight manual.
How is the Gulfstream Aerospace G550 hydraulic system arranged?
The Gulfstream Aerospace G550 has independent left and right systems, each driven by an engine pump. The left system can also be pressurized by an electric AUX pump or by a PTU driven from the right system.
Are there APU restrictions on the Gulfstream Aerospace G550?
For GV-SP (G550/G500) airplanes with improperly applied APU enclosure sealant, a supplement prohibits unattended ground APU operation. It also prohibits in-flight APU use except in listed failure cases or for bleeds-off takeoff up to 5000 ft AGL.
What hydraulic fluid does the Gulfstream Aerospace G550 use?
The Gulfstream Aerospace G550 uses Type IV phosphate-ester fluid. Approved types are Hy-Jet IV, Hy-Jet IV-A, Skydrol LD-4 and Skydrol 500B-4.
What is the Gulfstream Aerospace G550 Model Guide?
The Gulfstream Aerospace G550 Model Guide is a model guide for the Gulfstream Aerospace G550, dated 2026.

Hydraulic system layout
Left and right systems are each driven by an engine pump and have no common fluid point. Elevators, ailerons, rudder, spoilers and speedbrakes use both systems. Gear, brakes, nose wheel steering, flaps and ground spoilers depend on the left system. Backups are the AUX electric pump, the PTU, accumulators and a nitrogen bottle for gear.
Servicing and condition checks
Approved fluids are Type IV phosphate-ester: Hy-Jet IV, Hy-Jet IV-A, Skydrol LD-4 and Skydrol 500B-4. Left system capacity is 20.6 gal, with 5.7 gal in the reservoir. The service panel is under the tail. Ask for fluid records, leak history, and AUX pump and PTU test results.
APU supplement (GV-SP)
The supplement applies to GV-SP (G550/G500) airplanes with sealant improperly applied to the APU enclosure, serial number 5001 and subsequent. It prohibits unattended ground APU operation and restricts in-flight use. Ask the seller whether the airplane is affected and whether the sealant was corrected.
Summary written by AI from the source document. Check the original before relying on it. See which parts of Sprinkle are written by AI.
Safety notes
- Supplement: unattended APU ground operation is prohibited on affected airplanes.
- Supplement: in-flight APU use is prohibited except after engine or generator failure, or for bleeds-off takeoff up to 5000 ft AGL.
- Supplement: dispatch is not permitted with any engine generator inoperative.
