aaronk25 Posted October 25, 2017 Report Share Posted October 25, 2017 Did a step climb in the natural aspirated J to FL210 then to FL230 going east bound from MN to New York. Huge tail wind like 100kts so it made sense. By myself, fl210 didn’t take too long. Ran 2 hours to burn off some fuel then got approval from ATC for slow climb to FL230. A “C” ain’t to far behind a J in power and it’s lighter too. You will make it.Sent from my iPhone using Tapatalk Pro 2 Quote Link to comment Share on other sites More sharing options...

I kind of like to watch the ground go by, I think 6500 is about the highest cruise I have done and 7500 on a RTS flight. Usually when there is a longer trip to do the cloud cover is low. What's the break even point for going higher vs how long the flight is? Try using www.1800wxbrief.com It's free, put in your numbers for your plane, climb rate/speed, cruise speed, descent rate/speed, fuel burn in different stages of flight and then save it for the future. There are a few different apps that make it easy to file a flight plan on there or you can just plug it in on their website. Then you select the time of departure and there is an optimize button to evaluate the altitude you chose. It will give you flight times and fuel burn for two levels above and below what you filed. Ie: if you filed 7,500 it will give you 3,500 5,500 9,500 and 11,500. It bases it on the winds aloft forecast. I've found it to be accurate to within about three to five minutes of my actual flight time. 1 Quote Link to comment Share on other sites More sharing options...
kerry Posted October 25, 2017 Report Share Posted October 25, 2017 I general fly 10.5 and 11.5 cross country. When crossing the sierra's I climb to 14,000. When clear of the range I go back to my cruising alt. Going 10,500 to 14,000 I seem to get about 300' per minute climb with just me aboard.

StinkBug Posted October 25, 2017 Report Share Posted October 25, 2017 I've had my C to 15k on a day when the DA made it about 18k. It took a while to get there, but flew pretty decent. Also climbed to 14k coming out of Denver heading west bound later on the same trip. With a little planning it's pretty rare to actually need to get that high though, even out west. 1 Quote Link to comment Share on other sites More sharing options...

Will give it a whirl. Quote Link to comment Share on other sites More sharing options...

Wait--Your C model will average 1,300 feet per minute to FL170? Even for Mooneyspace that's an impressive claim. Perhaps you mean in your K model Rocket conversion?

If the winds are xx knots and the flight is xx amount of miles then it makes sense to climb to this high I've always used the formula that my cruise time should at least be equal to my climb and descent time. The Rocket likes altitude for speed vs. fuel burn. The Lancair REALLY likes fuel down low! Tom 2 Quote Link to comment Share on other sites More sharing options...

It can climb a bit faster still but after 10k or so I need to tip the nose down a bit to keep it cooling enough as the air thins. 1 Quote Link to comment Share on other sites More sharing options...

How long does it take your REAL airplane to climb to FL17? 3 min? 4? Quote Link to comment Share on other sites More sharing options...

I'm just a lowly C pilot, but I could have sworn that Flight Levels in the US don't start until FL18???
