For context: I know what a hold is, I know why we have them, but this is something I have not heard before.
I was recently flying VFR outside CAS (Controlled Airspace) with a friend of mine and we was outside the London CTA. We thought it would be interesting to eavesdrop on Heathrows' FIN Director Frequency - 120.4 on the COM 2. We both heard a clearance which we couldn't quite get our head around, it was:
BAW819K, Turn right to Lambourne, cancel the hold, leave Lambourne 265
We both look at each other and go "Eh, that sounded different". Shortly we heard it again:
EIN1LT, Make a right turn back to Bovingdon, leave Bovingdon heading 180 degrees
Could anybody explain what this means? Any explanation?
