IAI Astra 1125

The IAI 1125 Astra is a high-speed, transcontinental mid-size jet that evolved from the rugged Westwind series. By moving the wing from a mid-mount to a low-mount position, IAI significantly increased cabin headroom and reduced drag, creating a ‘pocket rocket’ capable of coast-to-coast missions in the US. It eventually became the basis for the Gulfstream G100.

Key Features for GA Buyers

• Transcontinental Range: With the optional auxiliary fuel tanks, the Astra can legitimately fly non-stop from Los Angeles to New York, even against typical headwinds.
• Exceptional Speed: It cruises comfortably at Mach 0.80, making it one of the faster aircraft in its price bracket.
• Modern Cabin Ergonomics: The low-wing design allows for a flat floor and more ‘stand-up’ feel (5.6 ft height) compared to its Westwind predecessor.
• Gulfstream Pedigree: Since Gulfstream acquired the line, owners benefit from a more robust global support network than many other legacy jets.

Trade-offs

• Runway Requirements: Unlike the Citation series, the Astra is ‘runway hungry,’ typically requiring over 5,000 ft of pavement at gross weight.
• Payload Sensitivity: While it has great range, carrying a full load of 9 passengers significantly limits fuel and requires careful weight-and-balance planning.
• Narrow Cabin: While tall, the cabin is relatively narrow (under 5 ft), which can feel cramped on the 6-hour legs the aircraft is capable of flying.
