Hi All,

I have searched everywhere but cannot find any reference to this.

I was out at YMML earlier this week sitting under the approach to RWY16, and noticed some new infrastructure on the airport perimeter. There are 32 strange looking black objects lined up horizontal to and directly under the approach, which make a strange upward inflecting siren that goes about 5 times every time a jet goes over them (did not make sound for the smaller, slower props).

The only way I can describe their appearance is that they look like plant-pots that were designed by the same people that built the F117 Nighthawk  confused 

Are these anything to do with the CatIII upgrade that they are looking at for YMML?

Thanks,

B727-200.

B727-200, I guess you mean this one? Sorry I also don't know what they are, but thought putting a picture will help on what you are asking for.

Cheers,
Mehdi.

Hi Mnazarinia,

Thanks for putting the photo up - I didn't have the camera with me the day I was out there and they are really hard to describe.

I hope you don't mind but i have sent the photo you posted to a mate of mine who works ATC at MEL. Hopefully he will know or can find someone who knows what they are.

Maybe they are noise adbatment monitors and maybe 16R has a new RNAV(RNP) approach and the authorities have decided to do a test. Something like; RNP SAAAR approach using Constant Descent Approach Procedures v. the traditional approaches to 16R.

Aussie authorites and a lot of the airlines have really imbraced CDAP and SAAAR/AR RNAV(RNP) approaches. I know Airservices and Naverus along with QF and a few other airlines are really investing and implimating these new amazing procedures!!!!!

Just my  twocents

Hi B727-200,

Sorry for the late reply. No worries mate. Not a problem, yeah I was spotting last week which these objects drew my attention and just for curiosity took few shots of them. If you get back anything from your friend please let me know as well.

If it was installed for the RWY 34 or even 27 I would have accepted but doubt it. BTW we leave it for experts. On the final of RWY 16 is not as much of the 27 and 34 RWYS the residential places.

Cheers,

That does not mean anything, it could be a new (RNP) procedure that just address the missed approach phase for 16. (RNP) is not limited to the good side of the approach, there are quit a few (RNP) approaches with a very basic straight-in approach but the missed approach has RF legs, lower then stand RNP values, high climb gradients, and even special engine out tracks.

My mate at ASA reckons they are to do with the implementation of the CAT III Approach system at YMML. If this is the case it would make sense having them under the 16 approach as this is usually used in foggy conditions, and can almost white-out the airport when there are southerlies and rain.
