Methinks not " naughty" enough. You were still on radar so you weren't low enough

Yeah...Do sand dunes bend radar waves...it is raw glass

It was 'stress of weather'...such a georgous, clear, calm day I had no choice.

Sorry about the thread hijack...I'll stop now

The right answer? There is no correct frequency It's whatever you think it should be! Ahh, NAS, clear as mud.

CC....."bite me" on the Airbus thing mate...dont knock what you havent tried....

****su....ditto on your original/first post.....Have only to "read and do" my checklist before taking the Rwy to ensure said transponder is in the correct position......now ,does Boeing have a checklist like that!!!!????? ay.....seems to me its the Boeing blokes that seem to get screamed at the most.....PB

Pakeha Boy,

The thread was in no way directed at heavy metal, as we only occassionaly have an issue with that end of the operating spectrum.

More aimed at the relatively new and less experienced pilots (not always) and the GA fleet (not always).

I would like to think anyone flying something relatively sophisiticated doesn't need reminding.

Transponders

ST...did get that drift and it was more of a poke at CC on the Airbus thing....just a little fooling around really...your initial post I believe is spot on,and something controllers do have to deal with.....its importance??? fairly obvious really...PB

Could I also add, it would be nice if aircraft fitted with Transponders turned them on, even where there is no radar coverage in class G!!

It is amazing the number of times we are inbound to an uncontrolled airport, when someone calls airborne in a Baron, Chieftan, 402, etc... without turning on their transponder. A polite "could you please activate your transponder"? and then "look there they are, we are going to miss them, not where they said they were after all..." (it is considerably easy to visually acquire a target after first having their position from TCAS)

In the past I have always turned on my transponder even in the most remotest of places, it is interesting just when/where the transponder has been interrogated, let me just say, you certainly want to have it turned on if you fly in an area where there is lots of military jets getting around!!

Oh, so that's why an F-111 deliberately changed course and came over to say 'hello' once when I had my TXPDR on ALT in class G...!

Fortunately the charter pax thought it was cool rather than a close call...!

We have major problems with this in NZ too. As HH says, there probably needs to be a bit of education about the need to activate your XPDR in Mode C in ALL airspace. Although I do think that if the altitude reporting feature is U/S or incorrect, the transponder should be turned off when outside controlled airspace, particularly outside SSR coverage where there is no SAR advantage to having it on.

One excuse I've heard from chopper pilots is 'I was only just above the deck, so I didn't think I needed the ALT function selected', obviously showing a lack of understanding of TCAS (which could be forgiven if one hasn't been specifically educated). When you have scheduled airline (RPT) traffic operating in uncontrolled airspace, and into uncontrolled airports, you need to maximise the use of whatever safety nets you have.

Even more distressing, I've heard horror stories of inappropriate use of TCAS (TA only mode) on RPT aircraft leading to severe reduction in separation. Flight safety systems are only ever useful if they are understood, and used appropriately.

Kind of related to Cloud Clutter's response, there is one option given to select TA / RA that I am aware of (although I don't work SY APP - special case for a special place ) :

http://www.airservices.gov.au/pilotc...ilotsguide.asp

PRM Approaches

TCAS Selection: Pilots may select TCAS in the TA mode or maintain RA mode on receipt of instructions to contact the Tower
So if you are given the option, what do you, or more to the point what is your company policy, on what you select?

I can understand the TA selection to avoid an unneccessary RA on the aircraft doing the parallel approach - but what about the RA on the unknown one that climbs up under the step?

[QUOTE=Howard Hughes;2916357]Could I also add, it would be nice if aircraft fitted with Transponders turned them on, even where there is no radar coverage in class G!!
QUOTE]

In the not too distant past over the North Western portion of the Indian Ocean....A Saudi B747 missed an An124 by the skinniest of margins.
(he called it as roughly the distance from the holding point to the runway centreline)
Both were travelling in the same direction, same level, off Radar, A class airspace.
The captain of the Saudi was very unimpressed to say the least.
Reasons? Bombay ATC had lost the plot, and the Antonov had his transponder switched...OFF.
Many of the Eastern European companies used to do the same.
The Saudi guys had no warning of the other jet until it was almost too late. Luckily the Antonovs nav kit wasn't as accurate as the Boeings or it could have gone horribly wrong.
If I had a dollar for every time I have had to ask heavy jets to switch the transponder on, I could retire in luxury

So this is a good point for all to remember, not just the weekend warriors.

Could I just say that... it is MANDATORY that you turn your transponder on, if you have one, in ALL airspace. AIP ENR 1.1 section 71.1 refers. I suggest that a less-polite response be given if the TCAS target suddenly appears after asking them to turn it on.

ST....that couldnt be further from the truth.....thats why they give us detailed checklists....and even then weve been known to miss items...

Airbus pilots being a little sharper than Boeing pilots for sure...PB

The history behind the AIP quote is that it used to mandate turning TCAS to TA-only mode during PRM approaches. The idea being that an RA may give conflicting instructions during a breakout procedure. This was changed after the German/Swiss midair.

No argument from me...what is the old saying?

Airbus= Designed by idiots to be flown by geniuses

Boeing= Designed by geniuses to be flown by idiots

If Airbus pilots weren't just a bit smarter than the rest of us the aeroplane would have killed them all by now.

How do you tell the difference between an innexperienced airbus pilot and an experienced airbus pilot?

Inexperienced airbus pilot = "What is it doing now?"

Experienced airbus pilot ="****...it's doing it again!"



We now return you to your normal sceduled viewing

PS If it aint Boeing I aint going.

Chuckles:

Can I add a newie to the above, just got around to reading the latest Flight Intnl with a pilot report on the A380 and a really interesting update on the B787 Dreamliner.

New Generation Boing and Scarebus pilots = "have you fed the dog yet, I need to use the CCD to access the WTFAW page............. "?

I only fly my little plastic 4 seater, but as a PAX on the bigger ones, give me the Boeing every time.

I think Johny Walker had an ad once......"The scotch you would rather drink...or the scotch you would rather buy"

I am sure you would agree.

J

This is getting quite a Hijacking now....so to keep content up....and my Transponder is always ON mode C = ALT.....see some of us GA bottom of the food chain guys can do it too.
