There has been some conversation among pilots with the advent of Center as to what the speed restrictions are for fighter aircraft.
As you may or may not know, fighter aircraft don’t have any speed restrictions that could result in violations, in Infinite Flight. But just because you can do something doesn’t mean you should.
Since we use the FAA (US) regulations primarily for Infinite Flight procedures, the answer will probably be 250knts IAS or below at or below 10,000ft MSL, and 250knts IAS – M1.0 from 10,000ft-FL600. FAR 91.817
If you are approaching or descending into an airport’s airspace, below 18,000ft, you should be matching commercial aircraft speeds, not exceeding 300knts IAS.
This is currently just a guideline I can give you, there is not currently any hard set rules for fighter aircraft, only guidelines. Misha Camp, Infinite Flight Staff, stated “Tyler [Shelton] and I had a meeting about this recently, and we would love to bring something in the near future that can address this! It my be a little more complex than just written limits on the IFC as we would ideally have something in app too, and that is where the complexity lies”.
