The '''Mooney M20M Bravo''' is a high-performance turbocharged single-engine piston [[aircraft]] produced by Mooney International Corporation. It is part of the long-body Mooney M20 family and is known for its high cruise speed, efficient airframe, retractable landing gear, and distinctive vertical tail design.

This page documents the '''[[FlightGear]] implementation of the Mooney M20M Bravo''', an open-source aircraft addon currently under development.

== Overview ==

* Aircraft type: Single-engine piston
* Engine: Lycoming TIO-540-AF1B
* Developer: Philips
* [[Flight dynamics model]]: [[JSBSim]]
* Development status: Alpha / active FDM and systems development
* Source code: {{Github url|philip2012|Mooney-M20M}}

== FlightGear Implementation ==

The FlightGear Mooney M20M Bravo project is an open-source aircraft developed using the [[JSBSim]] flight dynamics model. Development currently focuses on building a stable aircraft baseline, validating the flight model in runtime testing, and progressively improving systems and visual integration.

At the current stage, the project includes:

* Aircraft directory structure and addon packaging
* Successful aircraft loading in FlightGear
* JSBSim FDM baseline
* Metrics, mass balance, aerodynamics, flight controls, propulsion, ground reactions, and external reactions
* Baseline property-binding and control-input fixes
* Integrated external 3D model
* Static FDM sanity checks
* Control-chain sanity checks
* Baseline retractable-gear FDM behavior
* Stabilized constant-speed propeller behavior for climb testing
* Turbocharged high-altitude climb testing up to FL250
* FL250 ceiling behavior validated with low remaining climb rate near service ceiling
* Pacejka-based tire model for improved ground handling behavior

The current implementation is still an alpha-stage aircraft and should not yet be considered a fully tuned or feature-complete simulation of the M20M Bravo.

== Current Development Focus ==

Current development focuses on:

* Cruise, descent, and stall regression validation from the current climb baseline
* Continued JSBSim FDM refinement
* Engine and propeller behavior outside the validated climb envelope
* Aerodynamic coefficient refinement
* Ground handling refinement
* Retractable gear behavior and animation infrastructure
* Systems scaffolding
* Continued model integration

Ground handling and airborne performance are being developed as separate validation areas. The Pacejka tire model affects ground behavior, while current aero-side testing remains focused on JSBSim flight behavior.

== Planned Development ==

Future development will include:

* Full POH-matched performance envelope
* Finalized cruise, descent, and stall validation
* Improved turbocharged piston engine and constant-speed propeller modeling
* Retractable gear system logic and animation
* Cockpit instrumentation
* Electrical and fuel systems
* Aircraft sounds
* Visual polish and liveries
* Cross-country performance refinement using available reference data

== Development ==

The project is developed as a community addon for FlightGear. The aircraft source files and development history are maintained in a public GitHub repository.
