I'm not doubting your word but where did you get your info and are these height differences going to make a difference in speed.
Thanks Mick

I got the heights from the Ordinance Survey maps.

It will make a differance, but only small amounts and it will depend more on the sdjusted altitude at the time.

The Raf list the Pod at 330ft and Long Marston(SCR) as 500ft(above sea level). I think this has been covered before on here? Same thread runing on another forum?

How does the adjusted altitude work.

[Bikermoore]

That is where my knowledge ends - Hopefully someone with more understanding of this can help?

There was a thread on here which listed the exact altitude, rise or fall of track and shutdown, length of shutdown etc which I took from Google Earth. Seems to have gone now though...

Corrected altitude takes into account the air density and humidity at any given time rather than the actual/physical altitude.

If we take the figures that Tog recorded and reported from Sunday morning at SCR (see eurodragster live report) as an example. At a temperature of 71.4°F with 1010.83mb of pressure and the dew point at approx. 57.2°F (?) then the corrected altitude was somewhere around 1100ft I think if my head is screwed on the right way.

Cooler temperatures, a lower dew point, and higher air pressure will lower the corrected altitude. More humidity, higher temperatures and a lower air pressure will raise it.

7m above sea level will be about right for York...if not lower.
