Why is the Fenix A320 weather radar not working in MSFS?
A blank Fenix A320 weather radar in Microsoft Flight Simulator usually does not mean the panel is faulty. First confirm that the installed Fenix and MSFS 2020/2024 combination supports precipitation returns; unsupported builds cannot be fixed with cockpit switches. If supported, test airborne in heavy rain with the radar and ND configured correctly.
Is the Fenix A320 weather radar actually supported?
Weather-radar support is build-dependent, and older Fenix/MSFS combinations have no usable third-party precipitation data. The controls may move and the WX indication may appear even when the simulator cannot supply radar returns to the aircraft.
Check the documentation or release notes supplied with your installed Fenix build. If weather radar is described as unavailable or INOP, a blank ND is expected. A working radar in a stock MSFS aircraft does not prove that the same weather interface is available to third-party aircraft.
| What you see | Likely explanation | What to do |
|---|---|---|
| Radar documented as INOP | The installed aircraft or simulator combination does not support it | Update if a supported build exists; otherwise no cockpit fix is possible |
WX appears but there are no colours | No precipitation, incorrect tilt or unavailable weather data | Run the controlled test below |
| Radar works in a default aircraft only | The default aircraft may use a simulator interface unavailable to add-ons | Confirm Fenix-specific support |
| NDs or other avionics are also abnormal | Power, initialisation, version or add-on problem | Fix the wider aircraft fault first |
How do I test the Fenix weather radar correctly?
A useful radar test requires confirmed feature support, an airborne aircraft and real precipitation ahead. Overcast cloud alone is not enough.
- Update the complete Fenix installation. Update the aircraft package and its associated Fenix components together, then restart Microsoft Flight Simulator. Mixing files from different builds can leave individual systems behaving incorrectly.
- Create obvious precipitation. Use a weather preset or custom conditions containing heavy rain directly along the departure path. This is a better diagnostic than relying on uncertain live weather.
- Power and initialise the aircraft. The NDs, avionics and inertial systems must be operating normally. If other displays are blank or unreliable, verify the full cold-and-dark power-up sequence before diagnosing the radar.
- Test after take-off. Ground inhibition and modelled radar logic can prevent a meaningful test at the stand. Climb safely and place the rain cell ahead of the aircraft.
- Set the radar panel. Select system 1 or 2 rather than OFF, choose
WX, use automatic multiscanning if fitted, and return gain to its CAL or automatic setting. Put tilt in automatic mode or close to neutral for the initial test. - Configure the ND. Use ARC or ROSE NAV rather than PLAN mode, select a moderate range and confirm the ND brightness is high enough. Pointing away from the rain or selecting an unsuitable range can make a working radar look blank.
- Allow the scan to develop. Give the radar a few sweeps while maintaining the rain cell ahead. It is not a 360-degree weather map and will not display conditions behind the aircraft.
Why does WX appear but no coloured return?
The WX legend confirms that weather depiction has been selected; it does not confirm that the radar has something to paint. We frequently see pilots testing beneath dark cloud with little or no simulated precipitation.
- Cloud is not a radar return: weather radar depicts precipitation intensity, not cloud boundaries or general overcast.
- Manual tilt can miss the cell: excessive upward tilt scans above nearby rain, while excessive downward tilt points towards the ground.
- Reduced gain weakens returns: use the calibrated or automatic position while troubleshooting.
- The cell may be outside the selected range: change range rather than assuming the system has failed.
- Heavy precipitation can cause attenuation: an intense cell may hide weather behind it. That dark area is not necessarily clear air.
The predictive-windshear control is separate from ordinary weather depiction. Enabling PWS does not make general rain appear on the ND, and clear-air turbulence is not something conventional airborne weather radar can display.
Does live weather have to be working?
Live weather is not required if a weather preset supplies precipitation, which is why a preset is the best isolation test. If the radar works with a preset but not with live weather, the aircraft is probably functioning and the fault lies with online weather delivery.
For MSFS 2024, work through our checks for missing live weather and online data. Restarting the flight without restoring the simulator’s weather connection will not create radar returns.
When should I reinstall the Fenix A320?
Reinstallation is justified only when the installed build supports radar and the controlled precipitation test still fails. Do not reinstall an aircraft merely because a documented INOP feature remains blank.
First remove control-profile, panel, avionics and weather modifications from the test, then load the Fenix in a clean flight. If other systems are also faulty, use our broader Fenix power, display and add-on troubleshooting. Persistent faults after that warrant a clean Fenix installation using the supported installer method.
