Different speed limits for different aircrafts

The Boeing 787 is faster than Boeing 737, but they use the same speed limit --350knots. Boeing 787 has max cruising speed 0.89 Mach. 0.90/0.89 Mach is too slow for it.
Thanks.

Blockquote I’m positive Infinite Flight uses the published aircraft design cruise speeds created by the aircraft manufacturer. And I can tell you that for the Boeing 787 dreamliners M.89

0.94M is far from 787 s max speed

I’m positive Infinite Flight uses the published aircraft design cruise speeds created by the aircraft manufacturer. And I can tell you that for the Boeing 787 dreamliners M.89 is not too slow but too fast at cruise as that aircraft usually cruises at M.85. As for the Boeing 737 it’s designed cruise speed is M.78. Also take into consideration as altitude increases the groundspeed increases and vice versa.

The 787-9 has an average cruise speed of .85, max cruising speed of .89 and max speed of .90. The limitations are as realistic as they can be.

FDS uses the real world Vmo/Mmo values.

Vmo = Maximum operating speed in knots.
Mmo = Maximum operating speed in Mach.

Typical cruise numbers are:

A320/737: 0.77/0.78
A330/A340/757/767: 0.79/0.80
A350/A380/747/787/777: 0.84/0.85.

Hope this helps!
