My Olympus arrived this morning so I would definitely like to come to the NPOD on 4th. Can you advise me  if I have a place and how to pay etc as soon as you can because I think I will travel up the day before and need to book a hotel for the night.

General Pattern Discussion / Re: Ground air speed vs air speed at height

Thanks for all the info.

Hi Graham

Wise words indeed and what a change of emphasis! ( Mind you, I'd be happy just to get
to the point of getting it right in the first instance  :)  )

Hi Peter

> ...  In extremis, this can prevent you rolling wings level, though not usually so high!

Gosh, I had no idea this could occur.

> ... since a comp with good weather is so rare.

Thanks

Mike, when I used to fly full size gliders, I was flying in Scotland looking for wave lift. It was a windy day in hilly country.  The briefing for the circuit was "don't fly behind the downwind boundary fence and be wings level by 700 ft on finals!  The reason for the high final turn was the 60 ft wing span which at 45 deg has a very different airspeed between the bottom and top wings.  In extremis, this can prevent you rolling wings level, though not usually so high!


Point to remember is that we fly in the earth's boundary layer which, on a windy day has lots of eddies (vortices) and can extend up to 700- 800 ft!  None of the academic papers are going to take account of the actual wind strength and direction on the day during your flight.  It is down to being aware of this unsteady flow, watching how it affects your flight path and adjusting to maintain the manoeuvre shape. 


Remember the videos of the last rounds at the Argentina World Champs.  When the CD rules it's OK to fly, you have a decision to make!  That's why we practice in almost all weather since a comp with good weather is so rare.


Good luck!
