NCL will be an operational 5 aircraft base for scheduling purposes. The latest QC is a standby, and will be principally stationed at NCL & EDI as a standby for Royal Mail and will position out to recover any passenger delays. Indeed there are days where 6 aircraft are needed, Saturday's for example as there are no Royal Mails, so a QC does not need to be on the ground. Similarly there are a few days in EDI where 5 aircraft are needed. G-GDFE will hop between the bases covering any tech QC's. So really EDI is 4.5 based aircraft and NCL is 5.5, but that's getting a bit fussy
