Popham - dog-leg approach on one of the runways, and rough/narrow runways.
Dog-leg approach, yes, but rough narrow runways
Don't think so, unless you're only used to a 1000mts of tarmac.
To quote from Popham's own website:
"Runway 21 (right hand circuit 800ft QFE)
Long, narrow, and a steady up slope, sometimes boggy at the threshold end in winter but altogether smoother than 08/26.
The general aircraft manoeuvring area is very poor in parts,"
So yes the runways are narrow, and not the smoothest. Quite a lot of PPLs fly from 1000m+ of tarmac! So as well for them to be aware.
No disrespect intended to Popham but for someone at/around my level of experience, as the OP is, it is definitely more challenging than the standard grass field.
