Mach Speed For TBM-930

Hello IFC,
Can someone please tell me what is the best mach speed for a tbm-930 at cruise. Thanks!

Hey, refer to this …

hopefully this helps :D

Hey! This unfortunately didn’t help answer my question. This shows a cruising speed for the aircraft but not the mach speed what I was looking for. Thanks for trying to help!

Max should be mach 0.50-0.55 try to cruise around there… :D Does this answer your question?

no problem have a great rest of your day and enjoy your flight :D

Man, I stick it at 230 at FL240. Usually get some good winds at that level. I did go up to FL270 from CHS to CYOW today though

I see people on other posts say 250-255kts, I’ve never been able to cruise at that speed over FL220 on here. The red line drops pretty quick and you’ll get an infraction if you cross it

The TBM does not cruise at a Mach number unlike other aircraft. Instead you should be cruising at an airspeed. Below are the airspeeds for an aircraft weight of 6300lbs (2858kgs). Adjust speed by 1-4kts for difference in weight. If you’re lighter, increase by a couple kts. If heavier than the specified weight above, reduce by no more than 4 kts. The speeds below are for a medium weight.

Me personally, I climb at 200kts and maintain 200kts all the way up to cruise since that will land me right at a cruise speed for most of my flights that occur in the FL290-FL310 cruise range.

Altitude Speed
SL 237kts
5000 232kts
10000 227kts
15000 222kts
18000 219kts
20000 216kts
21000 215kts
22000 214kts
23000 213kts
24000 212kts
25000 211kts
26000 210kts
27000 208kts
28000 204kts
29000 200kts
30000 196kts
31000 192kts
For legal reasons I cannot post the actual source of these numbers. That said, these are about as accurate as you’ll find out there. If these speeds are wrong, then you should talk to the manufacture. 😅

Hope this helps!

I get what you are saying but when you go over FL280 it automatically puts you in Mach speed.

Turn off speed, manually control your throttle to achieve the airspeed as published and then turn on SPD. That’s the only time that you should turn SPD on. I never use AP SPD in climbs as you’ll achieve unrealistic engine values (power & fuel burn). Give that a shot on all aircraft and you’ll gain more fuel efficiency
