I've got news for you Angus - people say ****.

They don't just say it, most of 'em do it as well.

Thank you Billy Connoly :-)

So, unless the GPS unit ALSO measures altitude, and can add a vertical
component to the calculation, it can not work for skiing.

They all measure altitude. A minimum of 3 sats is req'd for this to be
anything near accurate. They do measure actual velocity. Aircraft use
this information.

They were using TERCOM not GPS

Is fat the same as thick?

It's your choice, of course.

But I think far more people have found what Ace has written over the
years to be useful than have found yours to be so.

Which may only be because you haven't written nearly as much yet, of
course.

I agree with this post.

Ho ha, such a cretinous post.

Anyway, toss pot, in a pointless attempt to drag this thread back on
topic and away from invective, like yours, I am going to use a
windspeed meter to measure my speed.

will only be usefull on a still day, unless you get a reading while still
and then adjust as necessary.

the wind speed meters that I have seen have either a fan blade thing that
spins or a set of cups. which one are you going to use?

In the off chance that you are replying to me (with no quoted context it
is impossible to tell) I would wager that my credentials in that area
somewhat outweigh yours. In fact it would appear that the primitive
instincts of an amoeba more resemble rational thought than your
ramblings.

Nice one Einstein. The variations in density, static pressure, dynamic
pressure and wind velocity and direction will give you a far less
accurate reading than a GPS but if it satisfies you - crack on.

The background wind speed would need measuring like you say, and for
the most part, it isnt that windy once you are off the peaks and in the
trees say.

I got hold of a fan type for =A330.

In a tuck, and held in the hand, it will be in clean airflow so should
give an accurate reading.

I asked the company if there was any data on adjustment of read speed
for altitude based on the density changing, as one would for a wind
powered generator. They said it was not relevant, as the loading on
the fan is very low, which makes sense.

But, since it can be callibrated at sea level and at 1000 meters I will
verify their statement.

As regards static wind velocity and direction, it can easilly be
factored in.

So **** for brains, I am way ahead of you.

To you maybe. They are always going to say that aren't they?

verify their statement.

And how do you suppose you are going to do that?

No it can't and it varies around every corner and undulation.

Thank you for choosing this moment to reveal your ****wittery to the
world.
You can ignore my somewhat specialist advice or you can carry on. I care
not. The wind measuring technique is the cheaper "daddy on the welfare"
and less accurate technique. GPS is better and laser/doppler better
still. I suspect it's all nugatory anyway as you sound like the kind of
gadget collecting wanabee who "blasts" around blue runs in a spacker
racing snow plough thinking you look good. Then again, I suppose we were
all like that once.
