Is is the B pressure needs to be lower along with temp and humidity, to be ideal for racing?? Like these numbers here; 74F Partly Cloudy Feels Like 74F UV Index: 7 High Dew Point: 55F Humidity: 52% Visibility: 10.0 meters Pressure: 30.19 inches and falling These look like something I should like to run a 9 with?? Anybody a closet weather man??
barometric pressure Mike: Is that absolute barometric pressure or adjusted. i.e. did you get it from the track barometer, or the weather forecast? The humidity might be a touch high for optimum. Good Luck!! Jim
Forecast schmorecast Mike: Get the absolute pressure. Close to 29.92 or above is best. Or find somebody there with a weather station. The faster racers have them, ask them. If you can't find someone with one, call the closest airfield and get the density altitude. That will tell you what you need. Jim
Get out your handy dandy old time "rain guage". If the pointer is over "good", then it's good. :grin: Good luck. :TU:
Mike, Density altitude can be figured on a wheel available from any pilot buddy. I have one that I use once in ahile for figuring. It takes a little time but it can be figured. I will try and remember all the stuff for Noble and show you there if I don't see you sooner. Good luck tonight too man.........RIP EM'............
