First flight today

[=Mac=]

Roll rate seems a bit short of the 270. Perhaps there's a limiter on?

 

Well, I cleaned up the wings (pylons off) dropped fuel down to 700 lbs and flew 100 feet above Batumi runway at 200 kts, then pulled lightly into a 90 degree climb. I expected to accelerate briskly because of the T over W. But I got very, very slow acceleration (about 1 knot for a couple thousand feet then it began losing speed.) I don't think that's realistic.

 

I'm not complaining. This is the first few hours of EA, after all. But hopefully, that issue will be addressed soon?

Hi Mac and thanks for the feedback. This is quite contrary to the feedback we've had from our F-16 pilot SMEs.

 

Thanks

First Vipers were very light and could accelerate easily when going vertical. Starting from blocks 30 the structure gained more weight due to structural stiffness and new components. Als starting from only 200 kts is very low, and probably behind the power curve

at the same time blk 50 has a more powerfull engine than the block 30 or 40/42 have even with extra avionics weight gains it has a superior T/W ratio . It was largely regarded as the most powerful Viper variant for the longest time.

 

 

on paper it should even have a better T/W than F16A did.

Thrust for the F110-129 seems to skew by a few hundred pounds depending on the source. GE rates the engine at exactly 29,000 while I've also read it outputs 29,400 as well as 29,588.

For the roll rate if you try the stores config switch in the CAT I position this seems to sharpen the roll rate. i'm assuming the plane limits the roll rate with CAT III selected.
