    Air Traffic control failures

    https://cybernews.com/news/duffy-faa-air-traffic-control-overhaul-newark-us-transportation-secretary/ Seems something is going to be announced tomorrow. I suspect they will go for a bespoke system which will cost a fortune to develop. There are 4-5 systems out thier already a couple of which...

    Air Traffic control failures

    Seems to be a common issue in Europe and USA. Old hardware and software and lacking personnel. It's becoming a factor in most aviation threads in this forum. https://www.bbc.com/news/articles/c4g2gr7994lo

    Never heard of voltage phase jump before

    Thats how i understand it. I must have 80 of those gu10 on the farm. And you can't buy tungsten light bulbs any more in Europe.

    Spain and Portugal power grid collapse

    I will let someone that knows what they are talking about explain the pf stuff and leds and class A bulbs. When i got my solarinstalled the export contract had a heap of limitations and causes for disconnection. One of them was power factor. I have a 8.5kW ground heat pump 3phase with a...

    Smart grid allows the inverters to adjust the power factor of the output. I am setup to get mine to do it locally at my place. Also to note led lights are a pain in the bum for power factor.

    AA jet and Military helicopter collide over Potomac

    Well it seems that the root cause is a government agency of some flavour. I suppose they could try and nail it on the air traffic controller. The video above by the retired pilot from the squadron portrays what I would say is normal operations for dealing with this sort of thing. They...

    AA jet and Military helicopter collide over Potomac

    Is there anything about legal action by the pax relative's? I suspect making it too expensive will be the only way to stop it.

    AA jet and Military helicopter collide over Potomac

    To me both situations have common problems with language used and discipline.

    AA jet and Military helicopter collide over Potomac

    As a note there seems to be an outbreak of pissing matches between controllers and pilots at US airports. Mostly reported in industry media. I wonder if the FAA has been cracking the whip.

    they have put 4 of these in, in estonia prior to unhooking from Russia. https://en.wikipedia.org/wiki/Synchronous_condenser They are putting more wind power in this year as well.

    AA jet and Military helicopter collide over Potomac

    Sorry I got the jumble of letters wrong. ACARs allows us to email various people and get weather. CPDLC is the system for coms with ATC. And of course there are two different systems which don't talk to each other. But that's an international issue not domestic.

    Spain and Portugal power grid collapse

    Is there any data logs of grid voltage and frequency? I keep hitting security blocks when I try and get to that sort of data due to location.

    Spain and Portugal power grid collapse

    the one I am thinking of was commissioned around 2010 I think. Possibly to replace that one. Sorry to be geeky but we fly over it/to the right of it when we come into land on runways 24.

    Barcelona has a pretty big thermal generation plant over 800MW which is linked to steel production. I bet none of the steel went off line.

    https://metro.co.uk/2025/04/29/flights-cancelled-power-outage-spain-portugal-madrid-barcelona-22991117/ Now to be honest I think strike season has started in Belgium anyway so Brussels being cancelled is pretty much normal this time of year.
