Aero Commander 680FL

Overview

The Aero Commander 680FL, known as the Grand Commander, is the stretched, cabin-class evolution of the legendary Aero Commander line. By extending the fuselage by 44 inches over the 680F, Aero Commander created a true executive transport with a separate flight deck and room for up to nine passengers. It is powered by supercharged, geared Lycoming IGSO-540 engines, providing the high-altitude capability and significant presence required for corporate or heavy-duty utility missions.

Key Features for GA Buyers

• Massive Cabin: The stretch allows for a true “aisle” feel and executive club seating that rivals light turboprops in volume.
• High-Wing Visibility: Passengers enjoy an unobstructed view of the ground, and the low cabin floor makes entry and exit via the airstair door exceptionally easy.
• Rugged Heritage: Built like a tank with a robust airframe that has historically been used for everything from executive transport to hauling checks and mail.
• High-Altitude Performance: The supercharged engines allow for efficient cruising in the mid-teen altitudes, staying above much of the standard GA weather.

Trade-offs

• Engine Complexity: The geared and supercharged Lycoming IGSO-540s are sophisticated powerplants that require meticulous pilot management and can be very expensive to overhaul.
• Operating Costs: Between the fuel burn (often 40+ GPH total) and the maintenance requirements of the geared engines and hydraulic systems, the 680FL is a “deep pockets” aircraft.
• Runway Requirements: While the shorter Commanders are STOL-capable, the 680FL at gross weight needs a healthy amount of runway, especially for the accelerate-stop distance calculations.
