Schwerter_105 Posted October 17, 2020 Share Posted October 17, 2020 (edited) Ummmmm it seems that currently the F-16C in DCS is over-performing in terms of low altitude max speed, as shown in the attached pictures, currently a F-16C in clean configuration can reach M1.6 in level flight at 10000ft, when the NATOPS chart states that at this altitude the limit speed is M1.4 Edited October 18, 2020 by Schwerter_105 Removing the NATOPS diagram Link to comment Share on other sites More sharing options...

Also you will probably have to remove the diagram, it's probably against forum rules.

I also have read about the 800 knot test, but shouldn’t the vipers in service have some sort of safety mechanism that limits the max speed? (I’m not sure, just a personal thought) Edited October 18, 2020 by Schwerter_105 Link to comment Share on other sites More sharing options...
Schwerter_105 Posted October 18, 2020 Author Share Posted October 18, 2020 The viper modeled by ED doesn’t have the F100- PW-229 as listed in the diagram. Ahh yeah I didn’t notice that, thanks. but I think according to the data sheets from GE and PW the two engines have very similar thrust, so their low-altitude performance shouldn’t have that much of a difference. P.S. I believe the F100 has a smaller bypass ratio which would in theory make its high speed performance better than the F110 which we have in-game?

AEOLUS3 Posted October 22, 2020 Share Posted October 22, 2020 no body talks about that over-performing and over speed of F-16C because everyone is happy with that. He can escape so easy. Imagine, even AMRAM 120C can't catch this aircraft. On the other hand the pour F/A-18C is so draggy to a point where you can't even do A2A Link to comment Share on other sites More sharing options...

On the other hand the pour F/A-18C is so draggy to a point where you can't even do A2A Because both are a mostly accurate representation of the real FMs. A clean Viper at 1.2M at sea level is still accelerating at .25G per the HAF -1. With 6AAMs and a centerline pylon it just reaches 0 accel at 1.2M at sea level. Clean F/A-18Cs struggle to break 1.05 at SL. Their straight wing works against them when supersonic.

Bunny Clark Posted October 24, 2020 Share Posted October 24, 2020 the NATOPS chart states that at this altitude the limit speed is M1.4 To be a pedantic nit: there's no such thing as NATOPS for the Viper :smilewink::hehe: Oil In The Water Hornet Campaign.
