Gulfstream G100

The Gulfstream G100 (formerly the IAI Astra SPX) is a high-speed, midsize business jet known for its exceptional transcontinental range and efficiency. While it features a unique ‘square-oval’ cabin cross-section that is narrower than some competitors, it compensates with blistering cruise speeds and the ability to fly at 45,000 feet, well above most weather and commercial traffic.

Key Features for GA Buyers

• Transcontinental Reach: One of the few midsize jets of its era capable of non-stop West Coast to East Coast missions (e.g., Seattle to New York).
• Speed and Altitude: Capable of Mach 0.84 cruise and a 45,000 ft ceiling, providing significant operational flexibility.
• Sea Level Cabin: Can maintain a sea-level cabin altitude up to 23,000 feet, significantly reducing passenger fatigue.

Trade-offs

• Cabin Dimensions: The cabin is narrower (approx. 4.8 ft) compared to the Hawker 800XP or Citation XLS, which may feel cramped for some passengers.
• Runway Requirements: While landing performance is excellent, MTOW takeoffs require over 5,300 feet of runway, limiting access to some smaller municipal airfields.
