- Clemens Ceipek demonstrates a glider launch at Boulder Municipal Airport announcing the points where to land out in the event of a rope break or premature termination of tow (PTT)
I had my first lesson at MHG today and I had watched this video multiple times before the lesson. I felt like I already knew what to do and I was making the callouts based on the video and the altitude! However, it is a lot different on a flat computer monitor than in real life. Elliot's field in real life seemed to come much quicker and be a lot smaller than it appears on my monitor.
Honestly I like that. I know you were verbalizing it for the video, but wouldn't this be better than calling out altitudes? I like this much more than calling an altitude to be honest. Keeps the thoughts clear and the decisions predetermined to leave the only thing to do: flying.
Indeed! The common practice of calling out 200 feet is problematic for several reasons: 1st, it doesn’t tell you what you should actually do once you get to 200 feet. The implication is that you can turn around to get back to the airfield but it does not say which way to turn … if you have a cross wind and you turn with the wind, chances are that you will not make it back to the airfield at all because of the wind drift … also, whether you can make it back also depends on how far away you are from the airfield by the time you reach 200 ft. Imagine a heavy glider on a hot summer day and an airfield at altitude and a weak tow plane… you might be 2 miles away from the airfield by the time you reach 200 feet with no chance to make it back. 2nd, and even more important, the 200 ft call does not tell you at all what to do if there’s a problem below 200 ft. And why wouldn’t there be one? The whole point of an emergency plan is to consider every eventuality in advance so you know exactly what to do in case there is a real emergency. It could be a rope break but it could also be the tow plane losing power, or any other eventuality that would lead to a premature termination of tow (PTT). Considering “what would I do now if” in advance is the key point so you have made your decision in advance and are not wasting critical seconds trying to figure out what to do because by then it could be too late.
@@ChessInTheAir yes exactly. The startle effect is followed usually by "ok what now" and you've already eliminated that delay. My DG505MB on aerotow is a great example of your scenario of being far out by the time you turn back. Especially on a hot day self launching! I have a video of an epic poor takeoff. More to that story. It climbs and lifts off way better now. But that day it didn't!
