As for speed, we could use your help to check another possibility. According to
the specification, the first option after command 178 means "Speed Type". The only valid value is 1, which means "Ground Speed" (speed relative to the Ground surface). However, when creating the file, I used the value 0, which is saved by the FreeFlight 6 program when manually creating a flight plan.
The second and third parameters also do not match the specification, so we can conclude that the specification is outdated (or does FreeFlight 6 contain an error?). In any case, we can try to replace the speed type "0" to "1", that is, bring it in line with the specification. If, of course, you have the opportunity to make another test flight.
