But ChattyGPT sez you can add them?

Give me a sample RNAV flightplan for MSFS
ChatGPT
Creating a sample RNAV (Area Navigation) flight plan for Microsoft Flight Simulator (MSFS) will depend on your departure and arrival airports, as well as any waypoints or airways you want to include in your route. Here’s a basic example of how you can create a flight plan within MSFS:
1. Launch Microsoft Flight Simulator and select your aircraft and location.
2. Open the World Map from the main menu.
3. In the World Map, you can enter your departure and arrival airports by typing their ICAO codes in the “From” and “To” boxes.
4. To create an RNAV flight plan, you can add waypoints or waypoints along airways as desired. For example, you can click on the map to add waypoints manually or use the “Add a waypoint” option. This will create a flight plan line on the map.
5. To make the flight plan an RNAV plan, ensure that the waypoints are not too far apart from each other. RNAV flight plans are designed to provide precise navigation, so your waypoints should be reasonably close.
6. You can also use airways to create your RNAV route. To do this, click on the “Add an airway” option in the World Map and enter the airway identifier.
7. Make sure to set your desired cruising altitude in the “Altitude” box on the World Map. You can also set your departure and arrival runways if you have specific preferences.
8. Once your RNAV flight plan is ready, you can click the “Fly” button to start your flight with the chosen aircraft and route.
Please note that the exact steps and options may vary depending on the version of MSFS you are using, and there might be updates or changes to the software. Be sure to consult the MSFS user manual or documentation for more detailed instructions and to ensure compatibility with any mods or add-ons you might be using.
