That explains the cancellations on the Heathrow to Edinburgh route over the next few days. Up to 2 flights a day cancelled.

What does that actually mean in terms of reductions though? Is it a 10% reduction, 5%, 20%?

Will it mainly affect the busier peak times or throughout the day?

Short term pain but very welcome in the longer term. Amazing it's been paper strips for so long - but I guess this highlights the complexities of changing a wheel whilst the car keeps moving....

Indeed, I was impressed by the electronic system at JER 8 years ago in 2010.

especially for something as critical as ATC. The tower itself at LHR is already on electronic strips.

Remember that principle of yours KARFA and tell the flight deck when boarding when going into and out of LHR the new priority order is as follows:

1. My plane first
2.Then everyone else's



Back on topic, I really don't understand ATC at all, far too complex for me but technological advances are a good thing in many ways. However, like the pilots, and CC to an extent too, our lives really are in their hands so anything that makes it fitter for the 21st century and safer is a good thing.

I am prepared to hold a little if necessary to allow me to finish my drink

Sounds like this could get a lot worse if the report of Eurocontrol breakdown is correct.

Hopefully today's Eurocontrol problems will be isolated to today, and the NATS work can start unimpeded tomorrow. And I think we'd all want to send best wishes to Scott Pilgrim and all of NATS for a smooth transition.

For those who don't know how it works, there are some great posts in the thread on why fog causes delays created by Heathrow Tower, and in particular this post which explains the role Eurocontrol has in coordinating traffic.

Thank you, but I walked out the building for the last time a few months ago now. Word on the street however is that Eurocontrol issues today may postpone this EXCDS introduction tomorrow, have to wait and see.

Likely a blanket percentage reduction on each sector, and specific to that sector, though actual numbers I know not but able to be altered tactically as required through the ten day period.

Some of my former colleagues may hold a slightly different point of view. As electronic systems go EXCDS is rather a dumb one, there likely won't be any really significant benefits for Terminal Control in the electronic environment until the new combined operations room with its all new equipment and systems opens a few years down the road from now, imo...

from the FAQ's: Are any flights likely to be cancelled as a result of the disruption?
We do not anticipate any flights being cancelled as a result of the introduction of EXCDS. However, this would be a decision for individual airlines.

So whose decision was it? Any de-icing planned ?

https://www.nats.aero/excds/ is quite informative but claims

From the sidelines, I have to wonder how they thought that a 20% flow reduction wasn't going to cause some cancellations ! Thanks for the advance warning, Scott Pilgrim.

Does this affect LCY as well?

Interesting perspective - thanks Scott
