A little history: Manufacturing of the Baron P58 ceased after 1984 due to pressurization and ice competing with the King Air. – The 58P offers the same capability of the King Air at a much lower price.
The autopilot is an all-in-one system from Duncan with the Garmin and Avidyne systems which play seamlessly together. The aircraft easily gets to 240 knots. The pressurization is simple and smooth.
