.8 is pretty good for a p300E. What's fuel burn/range like at that speed?

Someday they will be cheap.....

VRB ABI - 3.29 hrs
Fuel Burn - 3705lbs

ABI - SEZ - 1.87hrs
Fuel Burn - 2370 lbs

SDL - VRB - 3.68hrs
Fuel Burn - 3890lbs

All these legs would have been FL400 - FL450.

Maybe they'll be cheap someday but its going to be a hot minute until NetJets quits sucking up all the production.

The fastest single pilot capable jet is the Phenom 300E. Here is Mach .8 at FL380 at ISA +1

461 knot TAS……..oh baby!

Swearingen SJ30, Mach 0.83. I truly believe that's the fastest aircraft that meets these criteria for the US:

Single pilot
Civilian
Standard airworthiness certificate

Interesting note - it has 12 psi pressurization, for an 1,800 ft cabin at FL490.

The old L1011's were fast. We flew them around at .86. The computer would store a couple old flight plans, so you could page through them and see what other crews had been doing. One day a Chief Pilot was out flying and he paged through the computer and saw a flight plan in there at .90. So he called the old Captain in and said "hey why were you going .90?" The reply from the grumpy old Captain was "Because the POS wouldn't go any faster." I've always loved that story! Sorry for the thread creep.

Used to work on the L1011 back in the early 90’s. I miss those.

Holy crap I never would have thought those things were so slow. I always knew they were heavy subsonic attack jets.. but really cruise is at 280ktas???? Lots of civilian owner flown turboprops will blow the doors off that. I would think they would be sitting ducks for SAMs

Engines are optimized for low altitude.

We used to operate at 300 knots all the time down low. Fastest I ever saw was a cold day and dis 365 KIAS.

You don't defeat SAMs with speed. They are MUCH faster.

Sj30 is an amazing airplane. Got to spend some time at their facility in TX recently with a customer that has one. The build quality is ... Mu2 like... :tape:

Is the SJ30 a real airplane? How many were made or are being made? Looked at their Facebook page and it seems to indicate 8.

Apollo 10!

Cheapest flying possible! (OPM)

Single Pil………ah 2/3 ain’t bad. :rock:

Lmfao. Otherwise all good?? :rofl:

And although I’m no aerospace engineer, don’t rockets technically use a form of jet propulsion?

No. A rocket only bangs and blows, a jet engine sucks, squeezes, bangs and blows. :dance:

…equates to 8.4 statute miles per gallon. In the big SUV territory.

Given, to large degree, interstate miles are roughly 22% longer than air miles, one could say equates to 8.4 * 1.22 = 10.2 equivalent road statute miles per gallon.

Well, that is how I like to do my version of this calculation. :-)

Not bad for a 300 mph SUV

What is the story on the SJ30? I did a quick google search and looks like they sold or went BK and haven't resumed production. I'm guessing the fleet size isn't anything more than a handful of a/c and service/mx takes quite a bit of planning.
