RSM location

Great panel! I was thinking about the Aspen E5, but the local avionics shop never worked on a skymaster before and didnt know the best place to put the RSM. Where did they put it on your plane?

Thanks!!

TBM uses 45 ~ 70 GPH per hour, depending on the performance profiles... 280K ~ 320K;

Call that what?
300 knots on 60 gph?

Around 5 mpg

Not significantly much more fuel than a 337!

Its not GPH but MPG that counts.

Oh yes, and overhaul, maintenance and insurance.

A C172 only uses 10 gph to go what, 105 knots?
So maybe 10 mpg.

I have a friend who prattles on about Mooney fuel efficiency.

I have told him, "It is not polite to discuss fuel efficiency in the presence of twin owners..."

The TBM 960 uses a gallon a minute once it starts producing flight power. Altitude drives speed.

On top of the cabin, back my the rear engine intake. I will get a picture for you.

I know you guys are talking non-pressurized here, so this is just for completeness.

For the pressurized birds, I'm told the roof of the cabin would require a DER approval for any additional holes in the pressure vessel. I don't think that's a big deal but does add some expense (and time?) to the install.

A guy that used to work at Aspen told me they like to put them towards the rear of a boom so they can run wires thru existing holes and just redo the sealant-- thus avoiding any changes requiring DER approval. I've never actually seen one done this way, but then this was a recent conversation and I've never looked.

Aspen RSM’s should be like a minimum of 24 inches apart. I am really surprised that this system is working for you
