Master Caution Warning Sound and TCAS?

[TurbofanDude]

When the master caution light comes on in the 737 NG, what does the sound that plays sound like? Is it like the top part of the Flight attendent call or more like a 3 toned warning horn? IF anybody has an example of it, please post it!


Also, does anybody know where I can get a full TCAS system vocab test recording from the 737 NG? I've always wanted to know that it really sounds like!

Thanks in advance,

Collin Biedenkapp,
Hopefully, 737-700 Pilot someday

Heh - there is no sound when the Master Caution light comes on - thats the funny bit - even on brand new planes just the MC light might come on without any annunciator light illuminating - forcing you to push both annunciators to get the light work... Its not the best system in the world - and rather crude for a plane that has only been built for ten years... (Well, from 90% recycled designs that might have been unchanged since 40 years )
Couldnt find a TCAS sound bite anywhere quickly - (possibly because there is no easily accessible vocab test) but here is a GPWS test:

If you have any more questions about the NG, fire away
Best regards...

Only have to push one six pack or the other for a Master Caution recall. Doing so will illuminate the fault on either annunciator panel.

Thanks!

I appreciate it! Thanks! I actually am an aspiring 737-700 pilot, and I am asking all these things so I can build them into the expensive simulator (700$+).

[STBYRUD]

Bushed: I don't mean doing a Recall, I mean that you sometimes have to push the annunciators to get the electrical connection right to get anything to light up at all...

[TurbofanDude]

I see

Wow, that is screwy! Thanks everybody!

And remember to release the sixpack slowly, otherwise it might just snap out and depart at high velocity hitting you in the face, well, or somewhere else.

[STBYRUD]

...and then you might lose it somewhere behind the pedals - instant NOGO... Not that this has ever happened in my presence

[Bushed]

STBYRUD,

Okay, gotcha! Agree whole heartedly about the crudity of the system.

[TurbofanDude]

Wow

Is it really that bad? I've have my hands on the real sixpack before, and it didn't seem that bad! Thanks for the heads up, I'll watch our for it!

It's not the greatest! It doesn't so much tell you what the malfunction is, as much as direct you where to start looking. The King Air had a much better warning system as far as I'm concerned.

What point are you at in your training or career? Best of luck!

[TurbofanDude]

Well...

As embarrassing as this is, I'm actually not quite not enough to get my license or get into a full motion sim, and the sim I was referring to WAS actually a Microsoft Flight Sim that I spend hundreds of dollars and hours and hours of work on tweaking to operate very realistically. The 737NG and Classic I have both operate almost exactly like the real one. I am trying to learn as much as I humanly can about the plane, and practice fly my sim as realistically as possible. When I can get my license, I will, but I can't do until at least 17 I think it is. So, I guess my stage would be pre-training?

If the test is a success "TCAS system test OK"
otherwise "TCAS system test Fail"

PS: if the IRS are not aligned yet, we get the "test fail" message
