Jez: there is no separation requirement, you are VFR, and once clear of the zone at long eaton or shepshed u are in an unknown traffic environment, we may well tell u about known traffic if we have time, but don't bank on it!! Personally I think 1500 feet around MArkfield would be VERY iffy coz of the high ground up to 1100ft, not only that but clear of the zone we do not have the authority to restrict your level up to 2500 underneath the CTA so it could only ever be local agreement between the clubs
On 27 u would get a LW departure, and on 09 a LE departure, the reverse inbound-so not sure i get what u mean? Do u mean the wrong side with regard to the right hand side rule??
Either way it is, as i said above ,only a guide line feature for vfr traffic-if u want to leave/ join on another route, alternate lvel u only have to ask and we will if we can.
