We got our 350 back from Stevens Dayton with the XP67A. I flew the trip from Dayton to Georgetown along with another 350 with 60A’s at the same altitude. Looking at Flightaware, both planes at FL280, I was roughly 40KTS faster. Total fuel burn on the other 350 was 372 gallons with a flight time of 3:40. My fuel burn was 446 gallons and 3:08 flight time. I would have gone higher to save fuel but I wanted the comparison at the same altitude. Owner took his first trip the to the Kentucky Derby and commented he liked the performance and that the noise level was lower in the cabin.

I want to start a petition to get our KA350 model changed to a KA367 as it performs at an entirely higher level with the XP67A. It’s a new class of King Air. Our climb rate is so much better, ATC now gives us higher altitudes sooner which saves even more time. We often are getting to cruise altitude 20 minutes faster than before. In cruise, we set book torque and are 40 KTAS faster than we were before with conservative ITT’s in the 770 range.
I have been very impressed the past month we have been flying with the XP67A.

Heck yeah the XP67A Upgrade is great! I have put about 240 hours on the engines so far. Just took a trip, Dayton to Naples FL310 – FL320 330 KTAS. Doing everything you said it would.

I’ve done a bit of contract work in an older CE-550. Having now seen both those, and our 350 in action it puts things into perspective. Leg times are nearly identical, the jet burns 33% more fuel and is significantly more uncomfortable in every way. I’m sure you know all this, but it was really interesting for me to see both aircraft side by side. Makes me really appreciate what we have.
The other big thing was time to climb. We can get to 34k in about 15-17 minutes. 28 minutes in the Citation.

“This great 350 XP67A that I have been privileged to help crew has now gotten RVSM approval with the new owner. Monday, 12/10/18, we made a trip from Phoenix to Nashville, filing for FL330 which we were assigned. About at the NM/TX border ATC asked if we could go to FL350. Since this would put the cabin just over 10,000 feet and since we had a couple of passengers, I said we could do that but would be requesting 330 again when available. The controller said it would be for just a little over 100 miles, so we accepted the climb request.
My mind is blown. Golly, the thing zoomed up to FL350 so easily! I truly believe the two-engine service ceiling on that beast must be above FL450, at least at mid-weights. The pictures show both the TAS (and GS) and the engine instruments. We were running Blackhawk’s “Maximum Cruise Power” torques and the fuel flows were now about 350 pph per side. The no wind Specific Range comes out to be (320 knots / 695 pph) 0.460 nm/lb, which is not too shabby! That we were still truing at 320 knots up there — and it was almost exactly ISA conditions — amazed me. What a King Air!”

It gets better with each flight because we keep discovering new features. The boss loves the noticeably quieter cabin from the 5 blade props. In the climb, we can peg the VSI all the way to altitude if we want with power left over. Or, we can climb at a comfortable 2000 FPM and keep our KIAS up. More power takes the worry out on top of the climb. We are no longer sitting on a pinhead at FL270. The faster cruise speeds balance out the additional fuel used. The upgrade is remarkable.
Matthew Miller, Chief Pilot, King Air 350
These engines make it a whole new airplane—it’s more like a rocket ship. Fully loaded, we level off at FL310 in under 14 minutes, and our normal cruise speeds are consistently 30-40 knots faster. But the most impressive thing to me is the climb. I deploy the vanes to climb above weather and don’t fall below 1,000 feet per minute all the way up. We save 40 minutes on one of our regular flights from Las Vegas to our hometown of Colombia, Mississippi. The boss loves it, and fuel consumption is just about the same as it was pre-upgrade.
