Glider Tow Rope Break At 400 Feet

One of the pre-solo exercises that glider pilots must be successful at is the "tow rope break" at 400 feet of altitude when having just departed the runway.
Of course the rope does not break .. rather the instructor in the back seat pulls the release.
Generally a glider can do a 180º turn to land downwind if it has 300' of altitude. While some gliders can do this with as little as 200', it's not recommended. Besides ... we've got trees! An exercise at 400' is pretty safe.
Once you have the runway made, you may as well set your aiming point for further down the runway so that you can come to a stop closer to the launch point so that you don't have a long retrieve. Many students will panic as they see the runway "running out". Add to the road and the river at the end of the runway ... well I supposed some folks could panic.
On a downwind landing, you do not turn off the runway. You have a higher ground speed and a small control input can result in more rapid movements than you can handle.

Hi Dave. To clarify ,this is 400' MSL ? ( 220 agl )

Being a training exercise, it was 400' AGL. You can see how much height is lost after release in the distance, and there's sufficient height for safety (in case the student makes a mistake or there is heavy sink) and to allow a nice long landing down the runway so it does not need to be towed down the whole length. In theory you could do a 180º turn and make it back from 200', but that's cutting it close. We teach 300' minimum as there are a good number of low performance club gliders out there.

@@davesgliding Well, I don't even fly. Medical grounds. Pun intended. But on the matter of height and speed I always remember a series of cartoons that were drawn to keep the pilots flying the F-104 Starfighter from entering some usually fatal situations.
One said "Flame out
Hy.Key 15.000Ft
A minimum 245 KIAS...
... Plus 5 for the kids
... Plus 5 for the wife
...Plus 5 for my life
Makes 260 KIAS
Low Key 8000Ft
On F.O landings, nurse your speed lovingly, 'cause if you don't, you will not love anything else!"
Same applies to height, I guess.
Great quickbit video. Looks like an eternity and it was just over two minutes.

@@The_Modeling_Underdog Sorry to hear about your medical. Oddly enough, I've been told (not confirmed) that a glider pilot license in the USA does not require a medical. Here in Canada, it does.
With a love of aviation, even those who cannot fly can still enjoy the passion. There's a lot of folks who acquire a lot of time and expertise on simulators. It's not the same, but it can still be fulfilling and you gain a lot.
With respect to speed and altitude, we say that airspeed is life, and altitude is options. With respect to airspeed, when approaching base and final I usually calculate my approach speed based on what the windsock looks like, wind forecast, and other visual indicators such as smoke, waves on rivers and tree tops. And then, if I'm not sure ... I add a few more kts.
