Flight testing and changes to the flight model
Three hours of (mostly) T-45 flight testing today, in order to nail some of the changes to the flight model I had in mind. Although I think the previous flight model did its job nicely, after some thoughts, work and time spent reading the flight manual, I've modified the T-45 file so that:
- The engine response is slightly quicker. In the previous version I wanted to give the user the "sensation" of a trainer and the fact the T-45C is not an F-16. But, the engine response was probably a little too slow, so some users have complained about excessive difficulties in formation flying.
- Drag vs Mach is now slightly lower below 0.80 Mach, resulting in a faster acceleration and more correct climb speed. Also, top speed is close to the nominal Mach 0.85 in most conditions.
- Extending the speed brakes will have a "nose up" effect. This was perceived as "not realistic" and criticized by many users, and I deleted that effect in the previous versions. But then, the flight manual is very clear on this so the effect is back to stay.
- Extending the flap has a "nose up" effect, too, while extending the gear has now a slight "nose down" effect. Again, this is to attempt to replicate what is reported on the flight manual.
- There is now a slight "nose down" tendency above Mach 0.8, again, as per the manual.
Not many changes, then - but as I said I was quite happy with the previous FM. The new one is slightly harder as the pilot will have to compensate for the configuration changes, but I think it is still an easy plane to fly and land - and should do its job in helping simmers to learn how to land on a carrier.
...and yes, as you may have noticed, not all the pictures above are about the Goshawk...
