Title: Airport Altitude
Post by: grasscutter on July 13, 2010, 06:44:24 PM
Can someone please explain why the altitude on aircraft that have landed shows as 250ft or 200ft instead of 0?

Thanks

Have you set your local airport in SmartView, and ticked Auto-Set QNH?  That will ensure that the altitude reads field elevation on landing.

I have smartview set for Southend and QNH is ticked , sometimes the altitude shows
0 Ground but most of the time flights stop at 300-245.
