I was able to take it out for a reasonably long flight and here was my impression. I'm tempted to do a little work on the fm/engine model...will definitely need to talk with the developer first.
Good:
- It's a C-5!
- My cold and dark default flight files are compatible with it, so C&D starts are a go.
- I can't go into much detail here because everything is very subjective. Bottom line is that I enjoy what I picked up for $30, and with a little bit of digital wrench turning it could be a great heavy to fly when not in the mood for something as complicated as a PMDG.
Given that, here's a list of what I think could be done better/fixed:
- Biggest problem I noted in the fm given that I've never analyzed a C-5M, which means I could be totally wrong; is that the body fixed x-axis (longitudinal) is offset from the atmospheric relative x-axis when defining lift and moment coefficients vs angle of attack. When flying straight and level at cruise, my pitch attitude varied between -2 and -4 degrees depending on load and altitude.
- Wrong engines; The defined thrust rating fits the TF39-GE-1C (C-5B) rather than the CF6-80-C2 of the C-5M. Pretty easy to fix though if desired.
- I changed the minimum throttle from 0.25 to -0.05 for a better range of throttle control.
- There's a little distortion on the PFD when looking straight at it, but it goes away as the view pans (you can see this in the pictures I posted)
- There's a couple of disconnects with the autopilot I had to get used to. First, on the Autopilot module above the PFD, units are imperial but on the FMS they are in SI. Also, when adjusting for optimum engine/aerodynamic conditions I always use Mach Number. However, on the PFD and I believe autopilot, it is set in knots and not updated until you change it again. So, you if set the FD to climb at a certain mach, you're actually climbing at a constant speed which is the mach number at the instant you set it, and will be steadily increasing the flight mach number as the climb progresses.
Hope this was helpful.
