Elmsett (West) and Crowfield (North) are other alternatives. They both have 100LL but are ppr.
Both have overnight parking. Neither has an instrument approach.
They will all require a taxi and are 5+ miles from Ipswich and 10 miles from Martlesham.
Framlingham (Parham) has no fuel, Woodbridge and Bentwater are not useable (runways are there but closed)
The only instrument approach is RAF Wattisham which has an ILS
Ipswich airport was closed and built on so there is no possibility of landing there.
Let me know if you need any contact details
