Also as most UK en-route sectors are manned by both a radar and a planning controller, you have to hold both of these validations for each of the sectors that will be band-boxed. In the case of the old Manchester East Bank total band-box, that meant 10 validations were required to work 133.8MHz, during the short time it was single-manned in the wee hours on night-shifts.
