10,000 FEET! HOW COLD and HOW LONG TO FLY a Weightshift Microlight there? What about Oxygen?

How Fast can a Microlight Flexwing Trike Climb to 10,000 Feet AMSL?
PART 1. (Part 2 includes views of Fraser Island and the Gliding Descent).
Ever been alone.... at 10,000 feet? TEN THOUSAND feet! No one else - just you, the air around you, and the open cockpit aircraft. That's 3.048 kms, 1.893939 miles, or 120,000 inches.
Why are we here? And how long did it take to get here?
I'll be back in a moment to tell you after I find a warmer place to talk!
We will also test whether or not I can glide back to the airport - from 10,000 feet, but with one big added difficulty....
I know you have many questions right now.
How long did it take me to get there?
How cold was it?
What about oxygen?
Was it windy or turbulent?
How did I get back down - just joking on that one.
Getting there wasn't that easy because of where I live. I fly from Maryborough, Queensland Australia, next to a controlled airspace that I am not permitted to enter.
Why should that be difficult I hear you say.
Glad you asked.
This is a designated controlled north south airline corridor and it exists up from 8,500 feet. I am not allowed to go in there!
Fortunately the edge of the corridor is over the Sandy straits, not too far away. So if I climb steadily I will be able to reach it's edge of 8,500 feet just right, and then be able to continue climbing to my maximum legal altitude of 10,000 feet shortly after.
Let's go and start the flight ascent, and I will answer those earlier questions as we go.
How long did it take me to get there?
Watch the counter on the screen. Here are my flight planning calculations - approximations only using no wind.
We will be climbing at an average of 650 feet per minute from Sea Level to 10,000feet. Easy math 10,000/650 tells us 15 minutes. Climb speed will be around 60 knots. But I have to be careful not to climb too fast into that airspace at 8500 feet.
How cold was it?
On the ground it was 16 degrees Celsius. Lapse rate - or the rate at which temperature decreases proportionately with altitude - is 2degrees Celsius per 1000 feet. So 10,000 AMSL should be about minus 4 degrees Celsius. It was actually a pleasant +5 degrees Celsius. A temperature inversion must have helped me out here.
Oxygen ... is Not required at or below 10,000 feet.
Was it windy or turbulent?
There was a westerly 20kt wind as I climbed north, but it was quite smooth. Very pleasant at 10000 feet, i chose a great day. But of course its not always like this and even better, there were no clouds either.

Now THIS is the video I was hoping for! 👍👍

[@ttskfpr7583]

GREAT VIDEO, and learning experience!....

[@CrayonboxAviationAdventures]

Glad it was helpful!

[@Capitaine.Albator]

Awesome flight, nice camera and audio setup. Perfect. Thanks for sharing 👍🏻✌🏻

[@CrayonboxAviationAdventures]

Thank you too!

[@TheBioniXman]

You make out that 10k feet is something amazing. Done it many times in the Canadian Rockies in a P&M Quantum with a 2 stroke 582. Also done it many times in the south of France in a Tanarg/Bionix 912s. Most pilots will have done it too.

[@CrayonboxAviationAdventures]

It is for people that don’t fly. Being a pilot in itself is amazing to most people, and flying a trike even more so. Our maximum altitude here is 10,000ft so going there is special to me, because it’s unnecessary. Doing 90kts in a plane is not amazing either, but it is when you are in a trike. Hope that all makes sense, and thanks for your comment.

[@nyeahgarner2420]

That ain't nothin. I flew to the moon in a modified Ford Fiesta bro. Boo ya!

[@CrayonboxAviationAdventures]

@@nyeahgarner2420 haha, photos or video or it never happened ;-)

[@AM-cs9ld]

Is 10k feet doesn't excite you then it sucks to be you! 😊

[@alfred.g7521]

Flying in my favourite part of the world. Fraser island. Great footage and fantastic scenery. Looking forward to more.

[@CrayonboxAviationAdventures]

More to come!

[@AM-cs9ld]

Microlight flying is super thrilling and delivers a sweet sensation that's hard to describe. I'm doing my first gyrocopter flight tomoz. Can't wait for the flying buzz. 😁

[@vurujak]

Very nice

[@CrayonboxAviationAdventures]

Thanks

[@tonygreenbank8611]

I will always remember flying over lake Windimere and the rest of the lakes district in my flexwing at 13,500ft about 30 years ago. I could have gone higher but I'd be getting into Amber One. It was Easter Monday on a lovely sunny clear day that you only get in Spring. I did use some Wave lift to help to get up there, I could see all 4 countries of the UK plus the Isle of Man. Yes it was very cold but Ihad my thermal gear on. I remember looking down on the tiny specs that were boats on the lake and thinking, they are getting away from it all. But I am really getting away from it all.

[@Jozinko101]

Excellent video!

[@CrayonboxAviationAdventures]

Thank you very much!

[@jameslangford3613]

Subscribed! Great video! I'm looking at getting into weight-shift soon (currently 3-axis only) - can't wait! :) As a side note for anyone else thinking of doing this in Australia, be mindful of AIP ENR 1.7 section 3.1.4 regarding VFR cruising levels at or above 5000ft. I think being at 10,000 momentarily (as per this video) is probably fine, but best not to hang around!

[@CrayonboxAviationAdventures]

Thanks for the sub! I'm not sure how this applies to me n G class. I guess it doesn't... RE AIP ENR 3.1.4 Subject to ATC instructions, a VFR flight must be flown at a cruising level appropriate to its magnetic track according to Section 5. Table B or Section 6. Table B: a. whenever the flight is conducted at a height of 5,000FT AMSL or more; or b. if the flight is conducted at a height of less than 5,000FT AMSL whenever practicable (CAR 173)

[@jameslangford3613]

@@CrayonboxAviationAdventures The wording "subject to ATC instructions" is a little ambiguous, but I believe the plain English version is adherence to VFR cruising levels becomes mandatory at or above 5000ft, unless specifically told to do otherwise by ATC (which would of course be accomplished via FIA frequency in class G). This would mean a maximum cruising level for RAA registered aircraft of 9,500ft (east), or 8,500ft (west). Hope this doesn't come across as finger wagging! I just wanted to make people aware (I doubt CASA will be busting down anyones door).

[@CrayonboxAviationAdventures]

@@jameslangford3613 Yes got that. Hemispherical headings. Cheers.

[@jomalik206]

That was so cool! 😊

[@carlhopkinson]

I was at 13000 feet walking on a trail in the Rocky Mountains. It is chilly and the air is noticeably thinner.

[@sirclarencedarrow]

Very interesting and nice video. Here in Germany trikes, and other ultralights, are (mostly) allowed to fly up to 10,000' (FL100) with flight levels starting at 5000'. Above FL050 (in most situations) a transponder is required. Close to the Alps there are other rules, including a maximum of FL130. Class Echo is the air space I spend most of my time flying in, so this appears to be a major difference in the regulations between Australia and Germany. Class E starts between 1000' and 2000' AGL, depending upon where you are.

[@symcardnel1741]

Excellent everything my friend. I watch way to much 'outdoor' crap on utube and have to say that your production quality is super sweet!!! Love the bird... man what a beaut!!! For the gent below... being its a 912S that puppy's gotta run 60k USD right? Much beauty in the vid and I particularly liked 14:36. If I had any complaints it would be the 'logo' stuck in the upper left thru most of the video :(. Thanks for the great video and superb detail about the flight!

[@can5projects563]

awesome video my friend awesome video.

[@kimkeam2094]

interesting video, have you thought about crossbar mittens for your next high altitude run? What was the ground speed at 10,000? Thanks

[@CrayonboxAviationAdventures]

Hi Kim. I have mittens but it is normally warm enough here not to need them, so when I should use them I forget them. 😉 Ground speed on glide into head wind was 45-50kts (GPS). Interesting fact: I have since worked out however (and correct me if I'm wrong) that relative wind speed should be calculated using GPS and TAS (true air speed), not ASI (indicated air speed).

[@martinbraatz]

Gday crayonbox. thanks for the video. just curious whats your audio set up for this video.

[@CrayonboxAviationAdventures]

Check in my Avionics play list for the details on that. cheers.

[@kmuralikrishna1582]

Really appreciate But I have a question... Talking about the fly engine.. Generally How to measure fly engine capacity..? How capacity engine this video.? How many RPM ? Can we use electric motor instead of engine.,? Means that engine connect with propeller.. End of the day we need to propeller has to rotate in very speed right .? Kindly reply

[@larsthorwald3338]

Close to needing subtitles. hahaha

[@CrayonboxAviationAdventures]

Yes I know - can't change it now though - old tech audio setup 😉🤘

[@millimetreperfect]

I went to 10,000ft in a ‘Q’ with a 462, it took bloody ages!

[@CrayonboxAviationAdventures]

How did it compare with my climb? I thought I did pretty well, but I was on my on with 100hp on my back. Temps weren't too hot wither. 28-30C, but humidity wasn't too good.

[@flexflyer9049]

Hello. Were you using MOGAS?

[@CrayonboxAviationAdventures]

Being a 912ULS, the minimum fuel is RON 95 and that's what I use. Then there are the 98 and Avgax 100LL options - that I don't use. I think Avgas is a problem in these engines at this altitude - is that correct? Due to cooler temperatures?

[@sirclarencedarrow]

@@CrayonboxAviationAdventures Avgas is a problem due to the fuel containing lead additives.
