A big shout out to trike manufacturers... here in my corner of the world, we have the pleasure of having a bunch of NASA pilots visiting us, and in a moment of idle reflection I was just looking at the NASA Paresev from 1962 (worth googling!). In terms o

    "Bryan Tuffnell" commented on Rizwan Bukhari's Blog "Speed range in Strut wings vs Cable braced wing".
    ...and the extent to which the design allows the pilot to pitch the wing without needing a steady diet of protein bars, or having the wing start porpoising in phugoid oscillations, comes into it. Pitch stability of the wing and the geometry of the ...

    Mine too, Philip. Of course it can be hairy if the engine stops, but some things in life are worth a small risk.

    "Bryan Tuffnell" commented on Rizwan Bukhari's Blog "Another Trike Crash with two fatalities".
    Joe, we spin hang gliders by rolling against a partially stalled wing. By high-siding the stall without pitching in, billow shift flattens the lower, stalled, wingtip, raising its angle of attack further and exacerbating the stall. It's a very ...

    Wexy, everything is worth considering and we're all speculating. The only thing I'm confident about is that any time you're in the situation described by the eyewitness ("...aircraft banking to the left. The left bank steepened and the aircraft ...

    Paul, thanks for posting that info - I'll be passing that on to the Q2 owners here. I still see that 'increase in engine power' as something to note in this accident, regardless of what caused the initial roll. All speculation...

    Hi Andy. Thumbs-above seems to encourage me to pitch in when initiating roll or rolling out; it just seems to happen naturally. That's what I was referring to in this case. I find it far more relaxing and comfortable in turbulence. Larry M put ...

    "Bryan Tuffnell" commented on Rizwan Bukhari's Blog "Another Trike Crash with two fatalities".
    Noel, that's a fantastic example of what I was thinking of. And while Larry did mention stalls, I think it's worth bearing in mind that it's not just pilots that induce a lockout. I keep thinking about a comment made by a UK instructor that they ...

    There is a third scenario, although it's usually transient, and that's a big clue... and it can cause a tip stall... and some wings are more prone to this than others, but it can happen to all...

    "Bryan Tuffnell" commented on Rizwan Bukhari's Blog "Another Trike Crash with two fatalities".
    I think it was me that brought the term lockout from hang gliding towing to this site, intending it to mean "I'm trying to roll level without the assistance of reduced throttle and pitching down, and I don't why it's not working." I probably should ...

    "Bryan Tuffnell" commented on Rizwan Bukhari's Blog "Another Trike Crash with two fatalities".
    Wexy, the report provided by Lindsay says "...He noticed an engine power increase, followed by the aircraft banking to the left. The left bank steepened and the aircraft descended rapidly until impacting... IF that's correct, then we can be pretty ...

    "Bryan Tuffnell" commented on Rizwan Bukhari's Blog "Another Trike Crash with two fatalities".
    That's terribly sad. IF it was a spiral - if - then the cause, and the cure, are very well known, perfectly understood, and should be basic knowledge to everyone who flies a trike, and should never be the cause of a fatality. If the steepening ...

    Bryan Tuffnell wrote a new blog: "I am Yuri".
    I’d tried this game before, sneaking out while most people were snoozing to try a flight above cloud in the blackness of a moonless, mostly overcast night. I’d rolled onto Rangiora’s 25 near midnight, and sat there for a number of minutes ...

    Joe, I'll bet it looked great from the ground when flying low!
