Thankyou for your reply, I do have some small knowledge of this subject as I have been a load controller for about 3 years, before that I was a dispatcher for BM in jersey whilst they attempted CLC and eventually gave up due to the delays and endless mistakes that cost them money. Admittedly I am somewhat prejudiced against this issue, but it relies on all members of the chain knowing exactly what they are talking about and the consequences of getting it wrong, especially at the smaller airfields. It also helps if the people doing the clc know what the plane looks like and what occurs in the practical world. In jersey the crew have a tendency to request push and start stating they are fully ready, then spend up to 5 mins, holding up all manner of traffic, before taxiing or at the holding point waiting for the final figures. One might suggest that at the smaller airfields they consider obtaining final figures before pushing so as not to inconvenience all the other traffic that is ready to depart.
