Acclaim EGE to HPN

[Davidv]

Take a look at this flight and some of the other endurance trips: https://flightaware.com/live/flight/N142KR

apologies if this has already been covered but do you think there is some further modification to the fuel tanks or possibly a ferry tank?

Wow, that is cool. If it's got long range tanks option, it should be easily doable.

He filed for 183 knots at FL230. Must be a pretty low power setting.

[gsxrpilot]

He had a tail wind but has lost that now and is gonna have a head wind the rest of the way.

And yeah, he's not going very fast for an Acclaim. This is more like my 252 type speed.

[Davidv]

Definitely doing it on an economy fuel setting.  Certainly would be tough at best power settings in the Acclaim.

[Davidv]

Also curious given the weather in NY right now that he or she would also have the proper reserves for alternates even at economy power settings...

[gsxrpilot]

I think the long range tank option on the Acclaim is 125 gal. Which would be plenty of gas. But you're right, he might have to divert depending on the weather. But he's got another 4 hours to go and it will be after dark when he gets there.

I thought his climb was interesting. He initially leveled off at 15K then after a while climbed to 17K, and finally up to FL230. I guess that could be because of weight? But in my 252 I generally just go straight to my final cruising altitude.

My bladder hurts just looking at this.. .and I have a strong bladder... Ive done 5.5 hours in my glider while sucking on a 120 oz hydro pack!

 

In my rocket Id be doing about 215 knots TAS at that altitude burning about 16-17 GPH.   I dont have the 105 gal tanks but if I did.

Hr 1 = 20 gal

hr 2 = 37

hr 3 = 54

hr 4 = 71g

hr 5 = 88 gal

hr 5.5 = 95 g

And that would be that...  How can he get 10 hours!  Not even the lowest power setting would get me low enough to go 10 hrs!

 

Quite the flight!!

[mooneyspeed]

Long range tanks on a M20K might be able to do it. 104 Gal at FL230 and 9.5 GPH with that tailwind. Even have enough for 45 min reserve. Heck of a long time to be sitting in a Mooney though.

Guess he's been watching stinkypants . . . .

My bladder is fine, but sitting in the cockpit that long would be awful. I've almost reached five hours, and have been very happy to stand up and walk--four hours is about where I'm ready for the flight to end.

[gsxrpilot]

I just heard him on LiveATC. And now he's descending.

If you can manage to slow down....I find I do have a go slow setting that is LOP, 12.5 or 12.7 2200rpm 26'' and that will produce 180-190 in the upper teens.

But even with LR tanks - no way I could do that 10hr Western Colorado to Eastern NY flight - that's for the M20J or the 252 only - with LR tanks and astronaut diapers (depends) crowd.

Seems like he leveled off again at 18000. Is he still going for it?  With the speeds he is going in an Acclaim - and 125gal he may well be in slow-go go-for it mode still.

I would love to talk to you about LOP in your rocket... I have Gamis and still I find the engine runs a bit rougher when I try to go LOP.  That and the higher I am I seem to be fighting a battle with the TIT in that if I got LOP on the cylinders my TIT is too high.   I have 2 TIT readings, one stock and one on an old GEM.  I do not have much confidence in them.  I am thinking of replacing the TIT probe on the GEM because as I understand it, Old probes start to read High.

[Austintatious]

On another note... I love my Mooney and for a lot of the flying I intend to do, it beats the airlines in price and door to door time... This does not appear to be a flight I would want to do in it... even 2 airline tickets would be cheaper and a lot faster.  I doubt he has more than 2 aboard.

Hi - I am happy to chat LOP - here?  Or another thread? Or PM - what do you think?  Long story short - TIT is the limiting factor which limits the power I can do it - only lower power settings and not at the highest altitudes, and also there was a lot of work through the system to get it to run well even then LOP.  But it does!

Long Range on an Acclaim is 130 gallons and legend has it you can squeeze even a few more in there.

He's probably got almost 30 knots on the nose, so he's probably doing close to 180 kts TAS. And at only FL180, that's not super slow, even for an Acclaim

Its more fun to fly a long way like this in the summer.  Believe it or not - summer before last I flew to Bozeman Montana (with a stop) and even so in my Mooney it was faster door-door than with any airline possibility and not at all much more expensive.  Considering I live rural and its a long drive to the big airport then the parking lines. etc before you get off the ground - then 3 flights/2 connections to Bozeman.  And for expense - it was with my son and we brought bikes, and lots of fishing gear.

jeese!  What is the UL?  130 gallons is about 900 lbs!

780. So an acclaim with 950 lbs can still take a person

You know your max fuel capacity is too large when that phrase "can still take a person" is no longer true.

[gsxrpilot]

So he just checked in with Approach only 25 miles out and asked for vectors to the ILS. The controllers said, "do you know the field is IFR?" So he had to pick up a clearance and get a squawk code at the last minute.

How could he not be IFR after all that time enroute at FL23?

I see he is almost there.
