A320 Antennas Location
Could someone point out to me what the yellow antennas are on the following pictures.

TCAS is the fat white antenna further aft.
This aircraft appears to have three ATC antennas (Two on the bottom, one on the top)
Boeings usually only have two (shared between the Left and Right ATC systems).
What functions/systems are assigned to these three antennas?
Thanks

I saw that schematic before but it doesn't say which one is which exactly. From the two pictures I posted, there are four similar yellow antennas. Two of them must be the DME antenna. I assume the outboard ones. One is the ATC antenna but what about the other one. I always like to know exactly what I am looking at.

Forward is DME 1,aft is DME 2 as is shown on picture above, left is ATC 1,right is ATC 2, both shared also for TCAS . Antennas marked as TCAS * are directional only. If you find two uncommon white antennas almost same shape below the nose, it's MLS.

A320 series walkaround
I see the A320 has two ATC antennas on the roof as well.
Generally, to interact with TCAS, each ATC system needs an upper and lower antenna. The A320 evidently has 4 ATC antennas (two for each ATC system).

Sorry to start a bit of thread drift but I have two questions-
On the port side of the aircraft there are two AoA probes, Capt and Stby, but which is which?
On a CFM powered aircraft the pneumatic pre-cooler exhausts through some "gills" on top of the pylon. I was looking at an IAE powered aircraft and it doesn't have them on the pylon so where are they ?

Grille for precooler air outlet on V2500 is bit smaller in area and due to flat upper side of pylon is not visible if you look from position near engine. But generally is used same design like on CFM A320.

Bubi...the two antennas in your picture that are NOT on the centre line are the 2 lower atc antennas. The 2 that are on the centreline are dme antennas. The 320 family also have 2 upper atc antennas not shown in your photos.

Thank you all. I am writing an A320 study guide. I am almost done with it but occasionally I have questions. I am doing a preflight chapter so everything you can see (i.e: antennas, drains, access panels,...) will be in there. I have attached a few sample pictures of what I have done. If any of you would like to see the finish product, send me a pm.
