Just in a day's work for a 252

Germany to Canada to Oshkosh and back.  

Goose Bay to Reykjavik in 6:22, average speed over 200kts.

Don't even need ferry tanks if you have the Monroe tanks.

Ballsy! Love it. 

[shawnd]

For a second I thought you were back up and flying between the continents! 

Go 252!

I was talking to Jean-Dominique at Osh this year (I believe he flies a J) and he’s been across the pond 3 times. Said initially he brought a ferry tank but never used it. Subsequently flew without one. Turbo is nice but Long-range tanks FTW!

@Aerodon What power setting and fuel burn (and KTAS) were you using?     6.5 hours with IFR reserves on a (Assuming you have no speed brakes) 115 gallon tanks gives you a maximum fuel burn of 15 GPH, which isn't unreasonable.  

When I am at those altitudes (above FL210) and low power settings I need to hold some right rudder, which is annoying on long flights.  Does your plane have rudder trim?

[natdm]

This is absolute insanity. I love it. Curious about power settings, speed, etc. Just do a bad-ass write-up of it all.

• Fuel flow
• Gallons used
• TAS at altitudes
• Engine settings
• Gatorade bottles filled
• Did you have a plan for code-brown while over the water
• etc

[kortopates]

The pilot and owner is one of my clients in Germany. To my knowledge he isn't on Mooneyspace so I don't think we'll see him respond here

This is what I was wondering! 
 

I learned the hard way…travel John bags are single use only!

I have used them multiple times.  As long as you do no fill it.

Longest I did in my 252 was 7 hours, KBJC (west side of Denver) to 0W3 (NE Maryland).  Easy with Monroy.  I was at 17,000 (Basic Med), 2300, 29.5, 10.1 GPH, 175 KTAS, nice tailwind for up to 229 GS.

Not my airplane or trip.  But a 252 with long range tanks has 106G and will burn about 12.7 GPH at 75% and 190kts TAS at 18,000 feet.  Or about 155kts TAS at 9.7GPH.  
 

That flight had a really nice tailwind, so probably landed with about 30g of fuel.

Ahh...  Wasn't clear to me that you were not the pilot for that flight.     Actually that distance isn't as long as I thought it was.  Only 113 miles farther than the longest single leg I've done in my plane.   (S35 to KFFL, 1250.9 miles direct https://www.flightaware.com/live/flight/N5773S/history/20240518/1630Z/S35/KFFL  vs. the topic's flight of CYYR to BIRK, which is 1339.2 direct, and 1364 actual)

 

I thought the Monroy long range tanks held 115 gallons if you didn't have speed brakes, and 105 if you did.  I have the long range tanks and speed brakes in my plane and with patience was able to get 54 gallons in one side from completely empty.

 

[Pinecone]

The 252s have speed brakes.  Mine is placarded at 104 gallons full.  But I can squeeze in an extra 4 gallons (2 per side) if I have the time to wait for the fuel levels to stabilize.

That's impressive. I understand we, mortals, have to stop in Greenland?

I was surprised by that too.

Eastbound he had to stop in Greenland on the way over.

I'm curious about the Wick, Scotland to Reykjavik, Iceland leg without long-range tanks in a J. It's a bit over 4 hours with no wind, and you almost always have headwind that direction. I flew to Quebec City in a C340 (right seat - in charge of the radio) and that was the longest leg. I'm interested in trying it in my J, but that's the leg that makes me the most nervous.

A friend of mine met some friends of his in Alaska. My friend was flying a C340 and his friends had a 252. The Mooney flew directly from Canada (not sure where) to Reykjavik while the 340 had to get fuel in Greenland. I think the Mooney flew for something like 12 or 13 hours.

That's a hard pass from me. Plus the landings in Greenland are spectacular. 

[BlueSky247]

Man, those are some impressive numbers. But I can't help looking at that max service ceiling and the glide ratio and going "Nahhh, I'm good."  Unless my math is very wrong, you wouldn't even make it 40 miles in a J before you go swimming. I know Al did a twin prototype, but it sure would have been neat if they had been able offer those alongside the singles - for exactly this kind of travelling.

Wish mine was that fast.  Also wish I could run max cruise at 12.7 gph.  What CHTs do you see at 180 at that power setting?

Max cruise on mine, keeping CHTs to 380, I see more like 13.6 gph in the high teens.  That would give me more like 180kts at FL180.  Could still knock out a 6-hour leg no problem

[Pinecone]

Why burn 2.5+ gallons per hour more, for only 5 KTAS?

Just curious…what makes the landings in Greenland spectacular?

The fact you can get more fuel and not have to go swimming.

There's basically nothing around for hours except snow and horizon and places you definitely cannot land in case of emergency, and then you see a little landing strip off in the distance. The little landing strip obviously becomes a big runway, but it looks so small at first. It's just out there all by itself, with a few houses next to it, surrounded by nature for as far as you can see.

I was trying to find pictures, but my impulsivity got the best of me one night. The trip was one of the worst experiences of my life due to the guy sitting in the left seat, so I deleted a bunch of stuff that I now wish I had kept.

I found some... MS uploads photos in random order so the order you should try to look at is (1) the one with all the snow/ice, then (2) the end of the snow/ice, the beginning of ground, (3) the airport in about the middle of the photo, you can see two little buildings, which are actually two giant hangars, (4) the runway on approach

[Hank]

Great pics, Sue! Sorry the experience wasn't what it could have been. It's just a dream for most of us.

In these pictures, Greenland actually looks green! At least part of it, away from the stupid-high mountains.
