"[w]here the medical certificate requires another suitably qualified controller to be in the close proximity and able to take over in an orderly fashion in the unlikely event that the individual should feel faint or unwell."
"We do not think it unreasonable that the proximity endorsement should be provisionally in place for one year from the time of your last neurological problems. This would mean that we could review the limitation from April this year assuming that you have remained free from any neurological difficulties. Can I therefore ask you to write to us sometime next month along with a letter from your General Practitioner confirming that this has been the case and I am very hopeful that I will be able to lift your proximity endorsement forthwith."
