The UK’s Worst Airport For Flight Delays Revealed
The title of this post, is the same as that, as this article in The Times.
This is the sub-heading.
The shortage of air traffic controllers is a European problem but some in the industry have blamed early retirement during the pandemic
These are the first two paragraphs.
Gatwick was the country’s worst airport for delays last year as it struggled with air traffic issues and capacity.
Departures were an average of more than 23 minutes late, according to analysis of Civil Aviation Authority (CAA) data. It is the second year in a row it has topped the late league table.
It does look that the first paragraph is saying they need more air traffic controllers and that second runway.
Ironically, one of the adverts in my copy of the article was for Avanti West Coast.
London Gatwick Implementing Time-Based Separation On Single Mixed-Mode Runway
The title of this post, is the same as that of this article on Flight Global.
These four paragraphs introduce the technique.
UK air navigation service NATS has applied its intelligent arrival separation system to a mixed-mode single runway for the first time, with implementation at London Gatwick.
The system uses dynamic time-based – rather than distance-based – approach spacing in order to maintain sufficient arrival rates in strong headwind conditions.
Headwinds reduce the groundspeed of inbound aircraft flying at a set airspeed. This means a longer interval between two arrivals spaced a fixed distance apart.
“Having to maintain set separation distances in those conditions reduces the landing rate and can have a significant knock-on effect to the airport operation,” says NATS.
I have flown light aircraft onto main runways at major airports several times, including Cardiff, Dublin, Edinburgh, Hamburg, Leeds, Liverpool, Manchester, Naples, Nice, Southend and Stansted.
In one approach I made to Dublin airport, this type of approach may well have been of assistance.
I was flying into Dublin in my Piper Arrow; G-JMTT.
- I had crossed over Anglesey to leave Wales and I was talking to RAF Valley, whilst I crossed the Irish Sea in more of a direct line for Dublin Airport.
- The RAF handed me over to Dublin Approach, who gave me a series of vectors to point me at the main runway at Dublin Airport.
- Dublin Tower, then gave me the instruction. “Tango-Tango Can you speed it up a bit! There’s a Jumbo on your tail!”
- I replied. “Affirmative! Tango-Tango!” I then lowered the nose and pointed it at the runway to speed things up a bit.
- Dublin Tower, then asked. “Tango-Tango On landing, can you expedite clearing the runway?”
- There was then a brief exchange, where I negotiated my route off the runway, by taking the first taxiway on the left and then stopping.
- After a safe landing and a stop on the taxiway, Dublin Tower called. “Tango-Tango! We’ll give you ten out of ten for that!”
- After which the Jumbo rushed past on the runway, with the pilot giving a quick laugh over the radio.
- Dublin Tower called. “Welcome to Dublin!”
The Irish have different ways of doing things!
But, seriously, NATS are probably just implimenting a computerised form of what good air traffic controllers have done for years.
In that arrival at Dublin, the controllers had stretched the time and distance between my small Piper and the Jumbo, so everything was safe.
There alternative would have been to delay one of the planes.
Conclusion
It looks to me that the application of a new algorithm by NATS, will squeeze a few more aircraft into Gatwick’s single runway.
Thoughts On The Washington National Air Tragedy
I flew light aircraft for over twenty years as a hobby and to get about on business. I flew mainly in the UK, but flew for perhaps fifty to a hundred hours in Australia, France, Ireland, Italy and the United States. I flew planes on to islands like the Scillies in the UK, the Lido in Venice and the Barrier Reef in Australia. It was great fun and I enjoyed it immensely.
I had a friend, who had been an RAF Air Traffic Controller, who would be horrified at Trump’s remarks on diversity, as although he was white, he had been born in Tobago and had many ATC colleagues who were not white.
Flying around the world, most ATC personnel, try to smooth you on your way, even in France and Italy. But American ATC seems to work under unnecessary pressure because they allow planes to where British, French and Australian ATC wouldn’t.
I was told in the 1970s, that aviation experts, wanted to close National Airport, but the politicians wouldn’t allow it.
If I was Trump, I would bring in outside experts from somewhere like Australia, where in my opinion, they do ATC so much better than the Americans.
