Their talent for wasting money strikes again - now they’re the proud owner of a Thunderbirds vehicle that might as well be a paperweight!

Indeed, but boredom is often more tiring than working!

Edited to add, the ‘incident’ a few weeks back that saw aircraft return to their departure airports from airborne was due to controller fatigue.

The controller felt too tired to continue their shift. A bold but correct decision on the controllers part in consideration of the obvious consequences.

Genuine question

With GPS, why are ATC so important still?

Sorry in advance for my ignorance

Or put an unrealistically high reserve on and then sell it cheap on the quiet to whoever it was meant to go to in the first place.  With no public record of the price.

You weren’t supposed to work that out.

Could it not be converted to pull trains, you know for if it gets really wet.

GPS allows aircraft to know exactly where they are, but does not provide information about where other aircraft are. 

The only system on board aircraft that can tell where other aircraft are is TCAS (Traffic Collision Avoidance System). It will only work if the other aircraft is similarly equipped. TCAS can tell where other aircraft in the very near vicinity are, but not necessarily where they are going - vertically or laterally. TCAS is a safety system that issues collision avoidance instructions to both aircraft if they do get too close to each other. It is not to be used for navigation.
 

The main function of ATC is to keep aircraft a safe distance apart, on the ground as well as in the air, because they are the only ones who can do it.

They are also there for a multitude of other important reasons relating to the safe and efficient operation of flights.

So what about the 60k bid?  Sorry must be missing something.

Thanks for the reply but why not?

 

GPS knows where you are and computers can keep you apart, see the drone displays, so Why not?

 

Soon maybe?

Not in my lifetime I hope.

Even if the tech were ever to exist, I doubt that there would be much public appetite for it.

Was there not talk of an approach system that used gps for landing that was a pittance compared to what the airport was saying was required. Sorry to be used when approach was hindered by the fog or mist.

Yes, GPS can be used for approaches, and is done widely across the globe. The minima is typically slightly higher than for ILS though. You do need to have the approaches designed and published though, which we haven’t done here.

Prior to BREXIT we had access to a system of additional EU satellites which augmented the GPS satellites to provide greater resilience  and accuracy. When we had access to this, the minima was pretty much the same as it would be for CAT1 ILS.

However, the basic approach lights we have here would increase the minima of GPS approaches just as they do for the ILS.

Though the minima for non augmented GPS approaches are higher than for ILS, they provide a very good alternative, and would have prevented much of the disruption that we saw during the ILS replacement programme last year.

GPS can also be used for arrival and departure procedures, which would be useful for both ATC and flight crews.

As I said, we do not have any published GPS procedures here, which is a shame. I did read that the UK were looking at using an independent satellite company to provide the required augmentation to make the minima the same as the ILS seeing as we’d lost access to the EU’s system. Trials have apparently been conducted successfully.

Jersey Airport had GPS approach, arrival and departures drawn up, flight checked and published for the princely sum of £100K. They still have access to the EU satellite augmentation system so can use the lower minima too. They replaced their ILS last year as we did, but had little disruption because they could use GPS. Jersey have also said that because of their GPS procedures , they will probably not replace their ILS again at the end of this one’s service life.

GPS approach procedures would be a significant benefit here, even more so if we get access to an augmentation system again. The cost would, in the scheme of things, be peanuts too.

The approach lights would still need to be sorted though!
