Cessna 340

The Cessna 340 (specifically the 340A variant) is widely regarded as the entry-point into pressurized, cabin-class twin-engine flying. It bridges the gap between lighter twins (like the Cessna 310) and larger executive transports (like the Cessna 414 or 421).

Key Features for GA Buyers:

• Pressurization: The defining feature of the 340, allowing comfortable cruising in the ‘flight levels’ (up to FL250) above most weather, with a cabin altitude significantly lower than the aircraft altitude.
• Airstair Door: Provides a ‘big airplane’ ramp presence and ease of entry for passengers.
• Performance: With twin turbocharged Continental TSIO-520-NB engines (310 hp each), it offers respectable cruise speeds near 230 knots and excellent climb rates.
• RAM Upgrades: Many 340s on the market feature aftermarket modifications (RAM Series IV, VI, or VII) which increase horsepower, useful load, and climb performance.

Trade-offs:

• Payload vs. Range: While it has 6 seats, full fuel often limits the payload to just 2-3 adults. It is famously a ‘fill the seats OR fill the tanks’ aircraft.
• Complexity: As a pressurized, turbocharged, retractable-gear twin, maintenance and training requirements are substantial compared to unpressurized light twins.
