What is the cruising speed for the B738 and the A343?

For the B737-800, I'd cruise at around 0.78 - 0.80 MA depending on weight. For the A340-300, cruise at around 0.82-0.84 MA.

Thanks a lot!!

I am just doing a long flight at the moment from Paris Charles de Gaulle to Princess Juliana Intl in an Airbus A340-300 and I wasnt sure what the cruise speed was and I didnt try to guess because fspax is on and I didnt want to get the overspeed penealty

Thanks for the help

Have a nice flight!

The max speed is around 0.85 so depending on how fuel efficient you want to be combined with how quick you want to get there, 0.80-0.85 is good 😉

I'm at Mach .84 at the moment, autopilot constantly holding that speed for me 😉

FsPax is happy with that speed so its all good 😎

I just had a peek in the aircraft.cfg file for that aircraft and I saw these two entries

max_indicated_speed=330.000000
max_mach=0.860010

So it seems once it goes a tiny big over Mach .86 it will go overspeed.. so keeping at Mach .85 would be good then!!

Thanks for the help

I always try to leave it a bit below the max speed because ive hit turbulance a few times which causes it to speed up and then you will get an overspeed penalty.

OK I did the flight thanks for the help everyone

I made a good job of the landing which surprised me, its a hard approach

Glad to hear it 👍

If you all want to see the fspax report I have a picture of it [url="http://i49.photobucket.com/albums/f296/timbuk2006/fspax4.jpg"]here[/url]

There was a headwind for the majority of the way, thats why it took so long really
