Student Demo flight in Mountains with high winds aloft, record snow pack to Desolation Wilderness

eg: stopmotion, new-york, street
Join Paul Hamilton as he takes experienced student pilot flying a Revo trike over Lake Tahoe to Desolation Wilderness and Pyramid Peak in 30 MPH winds aloft. Here you get the story of how to fly in the High Sierra Mountains with high winds aloft. Spectacular views of the Sierra record snow fall in snow covered mountains south west of Lake Tahoe.

    That's amazingly beautiful Paul. You need to get some skis for your trike.

    Nice, Paul. I was expected to see a few jolts as you crossed the peaks but looked like you had smooth air.

    What happens on a sunny side slope with winds coming in from the sunny side? I would imagine you get some pretty strong updrafts then some strong drops on the lee side. You must have been high enough over the peaks to avoid that.

    What about winds coming in on a shady side of the mountain, does that lessen the updrafts or do you mostly just watch the winds and plan range top flying on that?

    Tom,
    I fly allot in the mountains in high winds. In this case, time of year (winter), time of day (morning) there was not that much convection (thermals) so the sunny side or shady side did not effect the air that much. Additionally it was generally a stable day with high winds aloft.

    Yes IN THIS CASE I could plan on range top flying and get away with it. But if you noticed on the lee/back side of Pyramid Peak for that one turn we were at full throttle and in a down draft. I was expecting we might get hit that is why I warned the student. I do my best to warn the student so they become aware of the situation and IF we do get hit it is not a surprise.

    Lovely video. This is a part of my training I have yet to undergo to better understand the interaction of winds and thermals in mountainous terrains. I understand some of the theory of the sun on one side warming causing up currents whilst the shaded side creates down currents and the wind across the tops creating turbulence, its the interaction between the two. For example, mountain with one side in full sun creating up draught, wind coming in and hitting the mountain on the same side must increase greatly the lift on this side whilst also increasing the down current on the opposite side due to rolling turbulence. Is this true Paul?

    Paul, how do you define high winds? What do you think the limits are for the average trike (not 103's)?

    Phil, Here's a good website: http://www.mountainflying.com/ . I've done some review and found snipets in the web page to be very good reading.

    Wowzer!! Tom, there is some heavy reading and math in there. I've put the page on favourite and think I'll have to re-visit rather a few times.

    Frank,
    I would define high winds for me to be anywhere from 10MPH for cross wind bumpy on the ground in large wing/light wing loading/ultralight to 50 MPH winds aloft smooth at altitude in a small wing/high wing loading trike such as the Revo. Two complete opposite ends of the wind limitations spectrum. Ground verses winds aloft. The best way to determine ground winds is the manufacturers wind limitations adjusted down to pilot capabilities. This is the basis for my "Weather to Fly" system for pilot safety. http://weathertofly.sportaviationcenter.com/weather-to-fly/

    Great video Paul, Thanks for taking us on the flight with you. That cover shot is excellent and could be a magazine cover. Best I've seen in a long time

    One question, what's the string for? Is it to show the side-slip?

    Amazing views. Many videos that play music. Here, Paul expertly explain what is going on. Superb! Fascinating.
    Watched it twice! Thanks Paul :-)

    Wexford,
    Not sure what string you are talking about, but if it is the one hanging out where the lower strut goes into the wing this is the tie down hookup. I keep these out since in high winds it is easy to get to and tie down the wing. It is something that can be easily reached in those tough high wind situations. Additionally, if there are chains at the airport tie downs, it is something to hang onto rather than put the metal chains onto my nice aluminum.

    I noticed how the seaplanes have some easy to grab tie downs for docking and I adopted this concept.

    Those are the ones Paul. Good idea, saves a vital few mins.

    Good editing and sound and great view. I enjoyed the whole thing with my greatgrandson. I want to fly those mountains one day. Looking forward to our 8th cross country to OSH this year. Our 7th in a Revo.
    Just wondering what the flapping chord was at the top of the wing strut. I think it is a safety chord for a previous camera mount.
    Thank you very much for sharing this one.

    Wesley,
    I do not put any safety chord onto any video camera (unless perhaps it could go into the prop) because if the camera fell off than it would be flapping and possibly destroy part of the wing and create a bigger problem. I would rather loos a camera than have one flapping against the wing in flight. I feel a chord to a camera is more of a hazard than safety. As I described above this is a wing tie down that I keep outside so I can get to it easily in high winds to safely tie down the wing. This has saved me many a time in high winds.......
