Two 747'S In Near Miss Over Scotland

randy hickey

Just saw this reported on Sky News and didn't see any mention of it here.

From:http://www.bbc.co.uk/news/uk-scotland-glasgow-west-24609183;


"The near miss on happened about 40 miles north of Glasgow on 23 June.

A report by the UK Airprox Board found that all four pilots had mistakenly followed instructions meant for the other crew.

At one point, the aircraft were just 4.5 miles apart horizontally and only 100ft vertically."

Here's a link to Airprox Report No. 2013054:

Minimum separation was 2.8nms and 600ft not 4.7 and 100ft. We always worry about it at there closest point not when they first lost separation.

In terms of ATC's part, it quite normal to have to aircraft at one level usually there is a plan but with weather happening at the same time it wasn't a good idea in this case as subsequently he got distracted from his plan.

As for the pilots as the airprox says htge pilots got busy and I reckon with the workload and all the numbers hdgs/callsigns etc they all got confused.

Unfortunately these things happen it's only human to error.

I am far from an expert but I would have thought there would almost be systems in place to prevent human error in this day and age.

TCAS ? I believe is what you are wondering about.
I believe when separation is below a certain point this gives guidance for avoiding action, only in vertial from what I read.

TCAS would provide the final safeguard assuming each set of pilots followed their SOPs. Modern ATC systems also provide controllers with colour graphics and/or aural alerts depicting aircraft that could be in conflict. That way a controller can issue avoiding instructions.
