Could a Shares or NJA pilot tell me what kind of HSC Mach & fuel flows you normally see at FL430/450 in the Sovereign?

Thanks!

About 1500pph and 0.78...thanks!

That's a little better speed and a little higher fuel flow than what Cessna shows in their Sovereign Flight Planning Guide.

FL400 .78 820 per side
FL410 ,78 800 per side
FL430 .73 -.75 760 per side. HEavy weights, max speed will be .73
FL 450 never been there. TAS is greatly sacrificed. Only go there is you are trying to stretch it out. likley will only get .70 - .73

FL430 is it's favorite altitude. If you're taking off heavy you won't see the far side of .73 for at least two hours. Towards the end of 4+ hour flight it will start creeping up to .78

Speed, handling, and ride are all lacking in this pig.

Say what you like but there are not many aircraft you can take off on a less than 4000 thousand foot runway and fly six or more hours. I think the aircraft hits it's sweet spot at 400 and 410

Compared to what, a Lear?
The difference between the Lear Mmo (.81) and the Sovereign (.80) is minimal. The major difference is climb speed and sustained cruise. The Lear will climb at 300/.78 and cruise at Mmo until you get over 450. The Sovereign climbs 250/.64-275/.72 and won't come near Mmo until you burn some fuel off.

The Sovereign handling is poor. The roll and yaw is very unresponsive when compared to Lears, King Airs/Barons, and even the Navajo.

The Sovereign ride is even worse. It's a very stiff wing. When the rest of you are reporting light chop we're getting moderate.

Well, the Sovereign *is* a Citation...compromising speed & ride for runway performance ain't anything new there!

All true. And be able to carry 1000lbs of bags with you. The aircraft has a very specific mission and does it well. The CL30 will do the same, do it faster, and with a better ride. Of course the 300 comes at a higher price point and then there was the whole pissing match we were in preventing us from buying the best aircraft for the fleet.

A lot of Cessna's shortcomings can be forgiven when looked at individually but become deplorable as a whole. But then again that is Cessna's nitch. They build the cheapest jets possible and to hits those price points compromises must be made.

A general observation that I have made is that I have yet to meet someone coming out of other Cessna equipment that didn't like the Sovereign. On the other hand, I have met very few coming out of other manufacturers who do like the airplane.

Just my observations, your mileage may vary.

Kinda like why NJA has 400XPs instead of CJ3s?

As a Citation operator, that jives with my experiences as well.

Good thing there are not that many 4,000 foot runways. Take this infrequent limitation away and the plane is a pig in all other respects.

A quick acuqwick search shows that there are 1900 US airports with runways 4000-5000 feet long.

Love the Sovereign

What other airplanes can leave Telluride in the summer at 72F, and take 5 pax with baggs non-stop to Sarasota, FL and make a 2.3% SE climb to account for the upslope runway (that their fixing)?

buehler?

buehler?

I have flown Lears, Hawkers (lol), King Airs, Baron's, a Navajo, and a Cessna 150. Nothing... nothing comes close to the Sovereign.

Oh and that Lear handling... Point the nose where you want the airplane to be in 3 seconds and push the power up. I wouldn't call it handling, I called it hangin on for dear life!

Two drawbacks that are far overcome by every positive...

1. straight wing does make a "bumpy" ride

2. Honeywell

I took 7 pax and mucho bags out of Ocean Reef in July nonstop to Chicago in a 680. Can your plane do that?
