You can see by watching others launch whether it's getting too strong. It doesn't really matter as you get to know your own gadget and how it's calibrated, and you know what your limits are relative to it.Īt your stage of training it wouldn't be high on my list of purchases. In my experience stood on hill next to people with a Skywatch, (the little ones at any rate) they seem to read 2 or 3 mph higher than mine, which is better damped. Are you going backwards, it's getting too strong. (A good one can be useful in the Winter too, as cold wind often feels stronger than warm.) As far a 'g' forces go, why would you want it mounted on your risers? You're not interested in measuring windspeed from your position while you are flying, or pulling a deep spiral? Groundspeed yes. I don't think the Halls is precise enough. oK if you wanted to know whether it really is touching Beaufort 7, or force 8, but as most pilots I know use anemometers to confirm their own judgement that it's marginally too light, or marginally too strong, a difference of 2 or 3 mph. 30 years ago there was an identical gadget called a Ventimeter. I have also, having sailed for a living for years, used things similar to the Halls. At the time I bought it about £35, now £47 (shrinked URL)windspeed_instruments/1366225 (It pays to mark name and phone number on it with a marker pen!) It was from Compass 24. I'm pleased to say I got my original anemometer back. (You can have that old e bay one for a fiver if you call around!) I took it for a walk down Brixham Breakwater (which you know well.) Despite almost being blown off the breakwater, and seeing loads of white horses, it read 12 mph? (It was well over 20mph) It may have been a 'bad' one, but I wouldn't waste my money on a cheapo. I bought one of those cheaops from e bay after losing my decent anemometer at Codden, N Devon a while back. Posted: Fri 9:53 UTC Post subject: RE: Hand held Anemometer?

Unless they have been drinking a lot of "spirits", I don't think your (a) and (b) have much relevance.ĭare to dream where eagles fly, but learn to fly where eagles dream! Back to top While much of what you say is certainly plausible, I'd have to add that I think the majority of PG pilots only pull out their preferred brand of wind meter at launch for observation purposes.

Reliance on the ASI for limiting airspeeds in high banked sustained spiral maneuvers will likely cause you to exceed the placarded speed limitations of the glider and will compromise your safety.ī) It is only accurate when within 15-20 degrees of the vertical orientation. If you are turning at a bank angle of more than 30 degrees, the ASI will read artificially low as a result of the G loading of the turn. Because of this the ASI has certain operating limitations:Ī) It is only accurate in one G flight. The design of the Hall type airspeed indicator involves using a ram air versus static pressure differential to raise a disc in a tapered tube against the force of the weight of the disc. Looks handy as a flight instrument too (till i get my ears tuned in to the airflow) Now that's an interesting device! Kinda looks like it should come in a brass "vintage" version! o) Shame it doesn't go below 7mph. Posted: Thu 16:03 UTC Post subject: RE: Hand held Anemometer? Posted: Thu 13:09 UTC Post subject: RE: Hand held Anemometer? if it sounds too cheap to be true then in all probability it is just that. Posted: Thu 10:36 UTC Post subject: RE: Hand held Anemometer?ġ. I used it once and it seems to work OK and gives the same readings as other makes so probably not a bad buy. Looks very similar to one that another pilot uses. Posted: Thu 10:06 UTC Post subject: RE: Hand held Anemometer? It's hard to find any info on the eBay one since it doesn't mention a brand or model name. It feels pretty solid like it will last for a while. I haven't tried it yet but it seems to be a tried and tested brand of anemometer. Posted: Thu 6:15 UTC Post subject: RE: Hand held Anemometer?
