Baron B55

Defining Style & Prestige

More than half a century has passed since the first Baron 55 rolled off the production line in 1961. A derivative of a derivative, the Baron was an offshoot of the Travel Air twin, which itself was largely a development of the Bonanza. Right from the start, the new Baron was a success. It was exactly as Beechcraft intended: a twin engine version of the hugely popular Bonanza.

Originally outfitted with 260hp Continental IO-470L engines, the model line underwent a few changes and re-designations, from the A55 with a 10" longer fuselage and a second fold-down rear seat, to the slightly longer-nosed B55 which remained in production until 1983 as the most numerous model built. The C55 arrived in 1966 with another increase in fuselage length and equipped with the more powerful 285hp Continental IO-520-C engines, later becoming the D55 in 1968 and the E55 in 1970.

Other variants based on the 55 arose, such as the turbocharged Baron 56TC in 1967, and the larger and more powerful Baron 58 which entered production in 1970. Ultimately, the downturn of the early 1980's signalled the end of production for the Baron 55, but the larger Baron 58 continues to carry on the legacy of style and prestige to this day.

Introducing the Milviz Baron B55

A luxurious classic that began life in an era of premium American brands, the Baron 55 has always given their owners a sense of pride. Our offering is based on a well maintained and updated Model B55, with a richly equipped interior that lends a sense of comfort and immersion.

A Pleasure to Fly

Continuing our reputation for producing quality aircraft, the Milviz B55 combines a highly detailed, carefully crafted model with sumptuous texturing both inside and out to recreate the experience of being in the pilots seat. Smoothly modeled 3d gauges convey a wealth of information and feedback to the pilot, with even the little features present in the form of a working legacy Stormscope radar gauge.

Meanwhile, the refined flight model is designed to replicate the crisp and stable flying characteristics of the B55, ensuring the ability to handle the Baron in close response to real world pilot reports. Performance figures closely follow the actual charts available for the B55, and as a bonus, a replication of the flying characteristics of the more powerful E55 is available as well.

Equipped for Anything

The virtual cockpit on the Milviz B55 represents an aircraft that has been updated to modern standards, while maintaining traces of legacy avionics. Along with the already-mentioned functional Stormscope, the legacy Century IV autopilot is still retained in the panel, although it's owner has long since been forced to disconnect it in favor of a more modern unit in the radio stack.

To that end, we've outfitted the B55 to include our Garmin GNS 530 & 430 units, a Garmin audio panel and Mode-S transponder, and a Bendix-King autopilot.

Third Party Avionics

Although the Milviz B55 includes our own detailed GPS units based on the default simulator data, we do recognize that many of our customers use other popular 3rd party options for replicating the GPS functions. For the B55, we've bundled in compatibility for the most popular avionics addons with multiple configurations available to choose from. Compatible 3rd party avionics include the following:

  • Flight1 750 GTN
  • Flight1 650 GTN
  • Mindstar 530 GNS
  • Mindstar 430 GNS
  • Reality XP 530 GNS
  • Reality XP 430 GNS

Please note that compatibility for the above gauge packages includes support for installation and setup of our product only; use of any of the offered options requires a functional existing installation of the appropriate gauge. In addition, any gauges we list compatibility for are not included with the Milviz B55.

Use of any 3rd party avionics package in any desired simulator is of course also restricted to the availability of the avionics package for that simulator. Please see the respective manufacturers websites for platform compatibility.
