I now accept that my earlier doubts were wrong - the curfew is deterring airlines from coming here. What I had missed was that without the restrictions, several Asian airlines would be able to fly from their hub to Adelaide and then on to NZ, then return the same way in under a day.

Also, aircraft are prevented from using 'Reverse Thrust' on landing and this alone prevents larger jets and regular passengers services from being able to safely operate within curfew.
I think the real question now is:
What would it take to enable large commercial aircraft to land with the wind behind them without using reverse thrust?
And is there much technological progress towards that goal?

I've not been able to find the answers to these questions - does anyone here know?

Reverse Thrust is simply re-directing the engine's hot output gasses to the front to brake the aircraft.
Its rather noisy however, which is probably why its been banned.

There is a simple technological solution, its called a longer runway :!: .
Still need to be aware of maximum landing speeds as well, don't want to blow tyres.

Planes land and takeoff into the wind to control the amount of lift that is produced over the wings.
It is simple physics.
It has nothing to do with reverse thrust.

And they will continue to land into the wind. Get over it...

Actually Pistol, a plane can land with the wind - it just means that it has to fly that much faster to maintain lift. Which means that on landing it needs a longer runway distance, or stronger braking. Obviously the higher the wind speed, the longer the runway needed.

The question is whether or not there is a workaround. Not as far as I know, but it would be interesting to know if anyone is working on it.
