HZ-HHT Aircraft Overview
HZ-HHT is a Grumman Gulfstream GIII registered in Saudi Arabia with serial number 491. This heavy-cabin jet operates in the wide-body segment of business aviation, positioned between super-midsize platforms and ultra-long-range flagships. The aircraft is associated with Aviation Knights, registered through the GACA.
Gulfstream GIII Market Position
The Gulfstream III entered production in 1980 and established the large-cabin, long-range business jet as a viable category. Its distinctive winglets were among the first retrofitted to a civil aircraft type. While most GIIIs have aged out of corporate service, the type served as the technological foundation for the GIV and subsequent Gulfstream models.
Performance Profile
The Gulfstream GIII delivers 476-knot cruise speeds with a maximum range of 3800 nautical miles under standard fuel reserves. That range covers most transcontinental routes nonstop and select transatlantic pairings with favorable winds. Power comes from 2x Rolls-Royce Spey Mk.511-8. The 45,000-foot ceiling provides routing flexibility above airline corridors and most icing layers.
Mission Profile
Heavy jets are the workhorses of corporate flight departments and head-of-state operations. The Gulfstream GIII accommodates up to 14 passengers in a cabin configured for meetings, rest, and extended travel. Baggage capacity and galley provisions support multi-day trips without the logistical constraints of smaller platforms.

Insider Note
Heavy jets carry higher repositioning costs than midsize aircraft. If the aircraft is based far from your departure airport, a deadhead leg adds significant cost. Inquire about one-way availability or empty-leg positioning to reduce the total trip expense.
