According to Navbox, the longest runway at "Barton" is 621m grass.
That is really short.
I have a 250HP 1400kg plane and would not go to 621m grass, unless it was really smooth, and conditions were ISA, etc.
Obviously there are many planes which can operate safely from 621m grass (mostly high wing and other low-wing-loading types) but to think you could fly a PA28-140 with four Brit-sizes blokes out of there... no way.
Is it time to retire some of these older aircraft
What is needed (if this is indeed an issue) is teaching pilots about aircraft performance
