The report into the efficiency of airfield operations at Perth Airport has highlighted many areas for improvement but what is needed urgently is a detailed examination of how plane noise in the area affected by it can be slashed.

Technologies and procedures exist to cut noise at least 30 per cent, and most likely much more.

One initiative alone - steeper descents to land - would cut noise 20 per cent.

Another uses satellites for a pinpoint approach path that can weave over industrial areas and away from homes, replacing the long, straight-in landing approach.

The same technology can be used in take-offs.

These, combined with changes to the way Perth Airport is used, including taking off from the end of runways - not halfway down as is common practice - would make the lives of affected residents immeasurably better.

So would banning refuelling stops in the middle of the night for noisy four-engine Russian transports.

Moving the airport and setting a curfew are simply not viable options. Therefore, it is essential to do everything possible to minimise the impact of planes, particularly at night.

Federal Transport Minister Anthony Albanese assured _The West Australian _last week that Airservices was working on modelling of these new technologies and procedures.

But there is some suggestion we will have to wait four to five years for the redesign of airspace to coincide with the introduction of the third runway, but that is simply not acceptable. Many of the fixes can be put in place within 12 months and must be fast-tracked.
