This is a modification to the MSFS 2020 default Microsoft Grumman G-21A Goose aircraft and is primarily aimed at improving the flight model to make its overall performance more closely match the actual aircraft, providing a much closer experience to flying the real aircraft. A number of changes have been made to the aircraft flight model and engine parameters, and the weight and balance, which are all detailed in the included Change Log file.
This mod is easily installed by simply unzipping the download file and copying the mge-microsoft-aircraft-g-21 folder to the MSFS Community folder. It will then replace the existing default Grumman G-21A Goose aircraft in the MSFS aircraft selection screen, and will also continue to utilize all of the available Liveries. To uninstall the mod and return to using the MSFS default aircraft, simply remove it from the Community folder.

Version 1.9.2
- ⦁ The default PILOT cockpit view position has been updated to improve visibility of the RPM gauges, and the overhead panel gauges. This also improves the forward visibility.
- ⦁ The COPILOT, CLOSE and LANDING cockpit views have been updated to match the new PILOT view, and to improve panel visibility.
- ⦁ Three new CUSTOM VIEWS have been created for sitting in the passenger cabin. Just press [ALT] + [NUMBER 0 - 2] to move to one of these Custom View locations.
- ⦁ The engine full throttle Max Manifold Pressure has been reduced to 35.5 in. to match the POH specs. This also provides a more realistic max climb rate.
- ⦁ A new forward keel Contact Point has been added to allow the aircraft to be realistically tipped over onto its nose. This also further improves the beaching realism.
- ⦁ The Flying Tips document has been updated.
- ⦁ The Flaps Extension and Retraction time has been decreased slightly to more closely match the actual aircraft.
- ⦁ The Flaps Drag and Flaps Induced Drag scalers have been increased to more closely match the actual aircraft, and to improve the final approach and landing performance.
- ⦁ The Ground Effect Lift has now been enabled to improve the landing performance and realism.
- ⦁ The Elevator Max Angle scaler has been increased to more closely match the actual aircraft.
- ⦁ The Default Takeoff Trim for a Runway start has been decreased to 1.5 degrees UP, which is also suitable for final approach and landing with the default loading and weight.
- ⦁ The Rudder Effectiveness has been decreased to more closely match the actual aircraft and improve the crosswind takeoff and landing stability and performance.
- ⦁ The Rudder Max Angle scaler has been increased to more closely match the actual aircraft and improve the crosswind takeoff and landing performance.
- ⦁ The Aileron Trim has been disabled, because this aircraft has none. Roll trim is achieved by switching tanks and burning fuel to change the aircrafts lateral weight and balance.
- ⦁ The max Tailwheel Steering Angle has been increased from 45 to 60 degrees to more closely match the actual aircraft and improve the taxi steering. This significantly reduces the minimum turn radius and makes it much easier to get into and out of tight parking spots.
- ⦁ The manifest.json file has been updated with the current version number.
Version 1.8.0
- ⦁ The Landing Gear Extension and Retraction Time has been increased significantly, to more closely match the actual aircraft. The landing gear on this aircraft are operated with a manual hand crank that requires many turns and a long time to fully extend or retract the gear.
- ⦁ The Landing Gear Hand Crank animation speed has been reduced to improve the realism of the hand crank operation, and match the more realistic gear extension and retraction speed.
- ⦁ The Flaps Extension and Retraction time has been increased to more closely match the actual aircraft, and to match the flaps sound. The flaps "thump" sound now coincides with the completion of each notch of flaps.
- The Hydraulic System is now driven by both engines instead of only one.
- The Hydraulic System Pressure has been increased to a more realistic level of 1600 psi to improve the operation of the flaps.
- The Default Takeoff Trim for a Runway start has been increased from 1.5 to 2.0 degrees UP. This is a better setting for both takeoff and landing with the default loading and full tanks.
- The Flying Tips document has been updated.
Version 1.6.2
- ⦁ The Prop Governor Min. RPM has been increased from 600 to 1200 RPM to match the actual aircraft specs, which also allows easier and more precise RPM settings to be made with the Prop levers. The range of the Prop Levers is now 1200 - 2300 RPM, as it should be.
- A PDF copy of the actual Grumman Goose Pilots Handbook is now included under the Documentation folder.
- The Flying Tips document has been updated.
- The Landing Gear postion and suspension have been adjusted to improve the lateral stability and ground handling.
- The Cockpit Ambient Lighting has been increased to improve the nighttime visibility of the trim controls and landing gear handle, as well as the other cockpit instruments and controls.
- For a nighttime Ramp start, the Cabin Lights switch, and Cockpit Lights will now default to ON, so they will come on as soon as the Battery switch is turned ON. This eliminates the need to move into the passenger cabin and manually turn on the cabin lights switch to get the cockpit lights on. For a daytime Ramp start, the Cabin Lights switch, and Cockpit Lights will default to OFF.
- For a daytime Runway start the Cabin Lights switch and Cockpit Lights will now default to OFF. For a nighttime Runway start, the Cabin Lights switch, and Cockpit Lights will default to ON.
- For a nighttime Runway start the Landing Light will now default to ON. For a daytime Runway start the Landing Light will default to OFF.
- For a Ramp start, the Fuel Tank Selector will now default to OFF. It should be set to RIGHT for startup and taxi, and then set to LEFT before takeoff as part of the standard engine runup checklist. This eliminates the incorrect MSFS default setting of ALL.
- For a Runway start the Fuel Tank Selector will now default to RIGHT. It should be set to LEFT before takeoff as part of the standard engine runup checklist. This eliminates the incorrect MSFS default setting of ALL.
- For a Runway start the Parking Brake will now default to ON, so you can perform the pre-takeoff engine runup checklist.
- The Supercharger Minimum Boost has been increased, which also slightly increases the idle RPM, to more closely match the actual aircraft.
- The RPM drop while running on one magneto has been decreased to match the actual aircraft spec of 40 - 60 RPM drop at 1,600 RPM.
- The Flying Tips document has been updated.
Version 1.4.0
- As requested by users, the aircraft Manufacturer Name that appears in the aircraft selection screen has been restored to the default.
- The manifest.json file has also been updated to allow the mod to appear correctly in the CONTENT MANAGER list as a COMMUNITY mod with the correct Author Name and currently installed Version number.
- A new overhead Panel Spotlight has been added to the cockpit lighting to improve visibility of engine power gauges. This improves both day and night visibility of these gauges.
Version 1.3.0
⦁ Although this aircraft does not have an autopilot, the basic MSFS Autopilot functionality has been enabled anyway for controlling pitch and heading. It can be operated by using the default autopilot keyboard commands, or by binding the autopilot commands to external controller buttons or switches.
Version 1.2.0
⦁ Two new Pilot and Copilot overhead Panel Spotlights have been added to the cockpit lighting, and the other cockpit lights have been readjusted to improve the overall realism and immersion of the cockpit lighting.
⦁ A new Flying Tips document containing all of the previous TIP OF THE DAY tips has been added to the Documentation folder.
Version 1.0.0
⦁ The default Pilot Viewpoint position and zoom level has been updated to more closely match the actual viewpoint of a male pilot. This provides better forward visibility and greatly improves the readability of the panel instruments. The default Landing, Close and Copilot views have also been updated to match the new default viewpoint position and zoom level.
⦁ The default Empty Weight CG position has been updated to more closely match the actual aircraft weight and balance.
⦁ The CG Limits have been updated to match the actual aircraft weight and balance specs.
⦁ The Fuel Tank positions have been updated to more closely match the 3-D model and the actual aircraft.
⦁ The Pilot and Copilot payload station positions have been updated to more closely match the 3-D model and the actual aircraft weight and balance.
⦁ Three new payload stations have been added to the Weight and Balance screen for the PASSENGER/CARGO compartment, the FRONT BAGGAGE and the REAR BAGGAGE compartments to more closely match the actual aircraft weight and balance. This allows more realistic loading and flight model performance.
⦁ The Landing Gear suspension has been moved adjusted to improve the ground handling and yaw stability during takeoff and landing.
⦁ The Tail Wheel Steering angle has been reduced to reduce twitchiness and improve taxi steering. While the actual aircraft uses a free castoring tail wheel, MSFS does not currently model that type of steering correctly.
⦁ A new Keel Step flotation point has been added, and several existing float points have been adjusted to improve the water takeoff and landing performance.
⦁ The flight model wing geometry, location and dihedral angle have been updated to more closely match the 3-D model and actual aircraft. This greatly improves the weight and balance, pitch stability and overall flight model performance.
⦁ The wing Center of Lift has been moved forward to more closely match the actual airfoil specs. This improves the pitch stability and overall flight model performance.
⦁ The wing camber has been increased from 0.5 to 1.0 to more closely match the actual aircraft airfoil.
⦁ The wing AOA vs. Lift table has been updated to more closely match the actual airfoil specs used on this aircraft.
⦁ The Horizontal Stabilizer Incidence angle has been reduced to more closely match the actual aircraft and improve the elevator trim during takeoff and landing.
⦁ The Control Sensitivity of the elevator, rudder and ailerons have been reduced when near neutral to improve overall stability and reduce twitchiness.
⦁ The default takeoff trim for a Runway start has been increased to 1.5 degrees.
⦁ The aileron span has been reduced to more closely match the actual aircraft.
⦁ The Rudder Max Angle Scaler has been reduced to reduce twitchiness and over controlling during takeoff and landing.
⦁ The Flaps Lift has been increased and the Flaps Drag has been decreased to improve the landing performance.
⦁ The ATC Type and Model codes have been updated so that the aircraft can be correctly identified during ATC communications, but currently there are no radios in this aircraft.
⦁ The Prop Governer PID parameters have been updated to improve the response time for RPM changes.
⦁ The engine/prop Thrust Angle has been increased to 3 degrees UP to match the actual aircraft specs.
⦁ Several of the Flight Tuning parameters have been tweaked to improve the overall stability and performance, and more closely match the actual aircraft.
⦁ The Landing Light brightness has been increased.
⦁ The non-existent nose mounted Taxi Light has been removed.
⦁ New ambient Cockpit Lighting has been added to make the cockpit and panel visible for night flying. This lighting can be controlled by the sim PANEL LIGHTS command, or with the forward Cabin Lights switch in the passenger cabin.
⦁ The Toe Brakes Scaler has been reduced to minimize over braking and tipping during landing.
