Sling TSi NEW Altitude Test! How High Can it Fly? 

Thank you!!

From my rough calculations 143 KTAS. Most likely WOT. Rotax 915 Turbocharged! It’s all in their videos.

Glad you enjoyed it!

Thanks!

It sure is!

Come fly with us! You won't regret it.

Thank you!

Thanks 👍

Thanks!

you won't regret it!

Thanks!!

@@SlingPilotAcademy I live in Tasmania Australia I don't think anyone is game enough to do it here although I reckon it would be easy because there is not much air traffic at the moment with covid and Lockdown etcetera.

Yeah - that was pretty funny.

12:00 Actually they hit 30.000 FT !!!

2 records in one! Be all you can be!

Thanks 🤗

Amateur hour. Not exactly sure how they got into RVSM either ....

ATC can allow local altimeter and path clearance for approved test aircraft.

You can operate an RVSM airspace if you want to, as long as your experimental aircraft is capable of maintaining 200 ft accuracy. If you've already done engineering analysis, which in today's time, means checking with GPS and making sure that your GPS calibrated altitude and your indicated altitude are within 100 ft of each other, You are fine. With modern technology it's easy to meet these minimum requirements. However, should there be a separation issue, and an investigation is done that shows your aircraft has never been capable of RVSM standards, You may be subject to penalty. Can an operator, in an experimental aircraft, operate in RVSM airspace (1000’ separation standard) if equipped with ADS-B Out? An operator may file a “w” in field 10 of the ICAO flight plan and operate in U.S. RVSM airspace with 1000’ separation if they meet the appropriate provisions of Part 91 Appendix G including Section 9, regardless of the airworthiness certificate they hold (Standard or Special such as for experimental operations). Appendix G, section 3 authorizes specific operators to operate aircraft with FAA certified designs that meet the specifications of Appendix G section 2 to operate filing /W. Appendix G section 9 authorizes operators of aircraft equipped with ADS-B OUT systems capable of maintaining an altimetry system error performance standard of not to exceed 200’ to operate filing “w”. It is important to note that ADS-B out provides continual ASE monitoring of an aircraft but does nothing to assure required ASE performance. An operator of a properly equipped and maintained aircraft with a certified RVSM design has reasonable assurance their aircraft ASE will not exceed 200’. An operator of a properly equipped and maintained aircraft that does not hold a RVSM certified design will need to complete appropriate engineering analysis and testing to assure their aircraft ASE will not exceed 200’. An aircraft operated as RVSM compliant (filing /W) under section 9 that exceeds 200’ ASE will be out-of-compliance with the rule and could also lead to investigation for reckless and or unsafe operations.

Thanks! about 27 inches

29,000 to 41,000 ft is RVSM airspace. Requires special aircraft and pilot requirements.

@@ryanadventureeverything8758 and also requires you to be IFR certified which I’m not sure these guys are

@@Captndarty IR required since they reach 18,000ft MSL

@@donnigunawan4446duh 🤦🏻‍♂️

Yes - we spoke with the Rotax engineers from Austria at Oshkosh last year. They have had drones over 30,000 ft as well.

Same question, aileron control must have been pretty mushy.

Did you switch the prop to manual or use auto climb all the way?

What was the actual time to climb to FL300? Also why evening? Wouldn’t have been cooler out first thing in the morning?

just trying to make video a little shorter

Just used auto. We tried manual on a previous ceiling test and found auto to work just as well.

We made it using mounting parts we bought on Amazon

We also had another complete oxygen system as backup.

@@SlingPilotAcademy could you tell me please, what was the throttle position at FL300 83 kias and 6.2 gph at 12:07?

Did you turn up the ignition timing to get the benefit of 100LL?

@@alexpl812 full throttle lol

Yes, we use a variable pitch prop in the Sling TSi

This is a piston engine so even if they get tossed around not much will happen after they recover

I was wondering the same, guess they're allowing experimentals everywhere. I fully support it as they usually have better equipment these days.

not a problem for us :)

Sling Pilot Academy Do you have data plots that show the intake temp during a range of operations? I am curious what you see on a hot day, say 90 degrees, during climb.

@@LTVoyager nope because they know there’s an issue and they don’t want to talk about it

@@Captndarty Yes, I am sure they did not meet the initial intake air temp specification and just ignored it as did many others. However, the good news is that Rotax just released a new manual and this value has been dramatically increased from 120 to something like 180 so it should be easy to hit now. I suspect the initial value was a mistake, but who knows what Rotax was doing or thinking.

@@Captndarty There's no issue. Max manifold temp is 80 °C (176 °F). Never comes close to that.

No pressurisation, just used oxygen

@@MrMinefeld Thanks

You'll be cruising at around 150 to 155 KTAS at 15,000.

Thanks!!

Agreed, aviation people seem compelled to use music to muffle the sounds we really want to hear.

RVSM airspace owners

If that's the ceiling, it can maintain it till it runs out of gas. I.e. If it can climb to am altitude it can stay there.

@@coolhari2000 thanks for the response. I am really impressed that it can fly that high. I guess it also would depend on turbulence at that level as well, since I presume it might not be able to deal with much of that.

RVSM compliant just guarantees you access to RVSM airspace. Controllers can still at their discretion allow any traffic into RVSM airspace. It's very rare that they did not access, but if they are extremely busy sometimes they will deny access to uncertified aircraft.

Wondering that myself. Be nice is " mums the word" would pipe up.

6.4GPH - Manifold Pressure 28.4 inches

And what speeds were you doing at that? Air and ground. What were the winds aloft?

It's illegal to go past 15k feet without oxygen.

@@coolhari2000 Yeah they should made a Law for that too, soo boring. Make me a Law when to breathe, and i will go free to the stratosphere 😂😂😂

They hit 30,021 feet

It’s a package deal. You can have lots of power, but it’s not much good without aerodynamic controls that are effective at that altitude.

You're right: Airframe, Prop' and Engine all have and impact. 915 does crush all previous models due to turbo, intercooler and injection!

Hope they actually read all the comments like this one.
