Update! MSFS2020 - Lockheed Martin F-22 Raptor Freeware Aircraft - V.0.1.5


The flight model and engine specs are based on my own research of the Raptor and similar aircraft like the F-16 and older fighters. I am not a pilot, so I make no guarantees that this aircraft functions like the real thing. It is extremely fun to fly though. High speeds close to ground level really taxes my machine, but lowering the graphics settings usually fixes any dropped frames or stuttering.

Quality of Life Additions:

Two invisible knobs added.
One is directly under the HUD that controls the HUD brightness.
One at top-left of dashboard which controls brightness of all other displays.

Known bugs/limitations:

Panel lights don't initialize to the on position when starting sim during day. This causes you to have to cycle the knob to off then back up to get panel lights to function properly(if the sim was started during the day).

Remember that turbulence becomes a real pain at high speeds. Per the specs for the F-22 listed on Wikipedia and the Lockheed Martin pages, keep speeds within these guidelines for the best performance:

Below FL300 - Less than Mach 1.2
Between FL300 - Less than Mach 1.8
Above FL450 - Between Mach 1.8 and Mach 2.2
For lower-end graphics cards (Mine's a 1070Ti) you may see artifacts in the HUD text when moving. If that's the case, set Anti-Aliasing to anything except TAA(which is default).

TODO/Work in progress(Not in order):

Need to start incorporating more controls into the cockpit and start arranging everything to match the F-22 correctly. I plan on keeping the G3000 and altering it to a design that looks similar to the F-22. A complete nav system rework for it is more than a one person job. [In-Progress]

Quick look cameras need updated for new cockpit. [Partially Complete]

I have no idea if the flight computer on the real aircraft could process flight plans for autopilot(most likely not), but I plan on incorporating it into it for a more enjoyable experience. [Works but interface (TMFD) is ugly]

3D model needs some more rework. Tires need to be flattened and not look like balloons. Creases need to be added to the underside of the wings. Creases need to be added for gear bay doors.

Fly-By-Wire not very responsive, doesn't hold altitude correctly.

Autothrottle not working as expected.

Need to make the high speed tape move with altitude.

ILS interceptions cause oscillations. Most likely need rollPID adjustment in ai.cfg

Fuel system needs worked into MFD's and needs to be easier to understand.

Fuel burn way too low. (Enjoying the range so fixing it is on backburner for now)

Fixed:
  • Autopilot PID values need readjusted for Pitch and Roll. Pitch shakes the aircraft like crazy when above Mach 1.2 below FL300 and above Mach 1.8 above FL300. Roll oscillates above FL450. Will be an easy fix, but time-consuming.
  • I plan on taking the EFIS from the G3000 and incorporating it into the HUD. I'll change the color from white to green and shrink it to fit the HUD correctly. Also need to redesign the HUD to properly resemble the dimensions of the one on the real aircraft.
  • Landing gear - the front wheel turns when turning the aircraft, but the wheels don't rotate when the aircraft is moving on the ground. I'm placing that on the back burner until the more major problems are fixed.
  • Textures need created for the underside of the aircraft. I just copied the one I created for the top. I also need to create textures for the inside of the VTails as I just copied the ones I made for the outsides.
  • If the roll rate in the flight model is increased to a realistic level for a figter, at max roll the jet goes to a 30+ degree AoA and stalls. Bug seems to be MSFS related as I've tried all different combinations of settings and can't keep it from loosing control. I have it set to a lower roll rate to keep it manageable.
Changes:
  • 12/28 - Further increased pitch and roll stability.
  • 12/30 - Added HUD Functionality.
  • 12/31 - Cleaned up HUD.
  • 12/31-2 - Forgot to clean up debug scripts.
  • 1/2 - Added wheel rotation animation. Made HUD Brighter. Added True Heading indicator to HUD.
  • 1/3 - Changed broken sound files for better ones. Adjusted max KIAS for more realistic settings. Starting to add warnings and cautions. Added Warning/Caution acknowledge pushbutton.
  • 1/4 - Exterior model update.
  • 1/16 - Revamped cockpit. Highly customized HTML Gauges, cleaner interfaces and overall better performance.
  • 1/17 - Bug fix.
  • 1/19 - Fly By Wire added. Cleaned up HTML Gauges.
  • 1/24 - Added air traffic tracking to SMFD Map (Real world Traffic only, bug prevents Offline AI traffic from displaying. MSFS Bug Report #90082). Made SMFD Map more MILSPEC. Increased map range to 600nm.
  • 1/24-2 - Added quickview camera definitions. Lowered HUD Opacity.
  • 1/25 - Cleaned up some code. Fly-by-Wire now off by default. AP airspeed bug now always displayed on PMFD. Changes to flight model(Last Commit - Forgot to mention)
  • 1/27 - CTD Bug Fix.
  • 1/28 - Added Landing Gear lever. Added brightness control for MFD Buttons/Panels
  • 1/29 - Page settings are now saved between flights. Panels are dimmer when sim starts at night. Display knob now controls all screens and screen button brightness. Added two invisible knobs(view README for location and use).
  • 1/30 - Fly-By-Wire settings save between flights. Fixed bug where pressing back button on MFD's locked up the screen. Wrote custom potentiometer to handle exponential functions and handle values less than 1%(HUD now gets MUCH dimmer). Moved HUD from default AS3000 template to custom screen templates used by the MFD's(should be small improvement to performance/framerate).
  • 2/6 - Complete Fly-By-Wire rewrite.
  • 2/6 - Added G-Force pitch PID that scales in between 300 and 400 knots. FBW now automatically disables below 100 knots. Removed yaw from FBW and went back to standard yaw damper. Landings with FBW are now possible.
  • 2/8 - Major improvements to Fly-By-Wire pitch control.
  • 2/9 - More Fly-By-Wire changes. Added Yaw Damping
  • 2/9 - FBW PID Adjustments, Roll input now a curve instead of linear.
  • 2/13 - Improved MFD Performance(Frame rate increase). Multiple HUD Improvements.
  • 2/14 - More HUD Work, Performance fixes.
  • 2/15 - HUD, Flight Model, and FBW changes.
  • 2/18 - FBW Changes(Disabled rudder above 35kft). Major HUD Changes. Cockpit view now closer to HUD. Flight Path Indicator more accurate.
  • 2/18-2 - More HUD Changes.
