Title: Boeing & McDonnell Douglas' GPWS, TCAS, and Callouts .
Post by: Аэрофлот Jr. on January 28, 2009, 10:48:11 AM
I made compilation of ALL of Boeing and MD's GPWS, TCAS and Callouts in my collection  :-)   Hopefully you don't hear some warnings in this clip when you are flying planes...

Very nice.  I think all of those (except for the very last couple messages) are McDonnell Douglas voice commands.  I recognize the annoying elecronic voice they used.

The TCAS RAs are always interesting, with all of the options of both levels of RA (I don't have my systems manual up, I don't recall what the 2 levels are called)

TCAS TAs are common, but RAs are fairly rare.  I occasionally got the "Adjust vertical speed" or "Monitor vertical speed."  Fortunatey never got the corrective and increasing RAs which get a little dangerous as you start to enter the realm of cabin movement.

@Cessna
I'd like to clarify some points you have raised about TCAS:

1. "Adjust vertical speed, adjust" is a corrective RA. "AVSA" requires a reduction to 2000, 1000, 500 or 0 ft/min, as indicated on the instruments. Any RA that requires a change of vertical speed is corrective. Incidentally, it's very often incorrectly flown (pilots increase the vertical speed instead of reducing it). This RA will be replaced by a new "level-off, level-off" RA (reduction to 0) in the forthcoming TCAS ver. 7.1 (implementation date still not known).

2. I don't think you're right saying RAs "get a little dangerous". They're not if flown correctly. Climb/descend RAs require vertical speeds of 1500 ft/min, increase climb/descent 2500.  The former requires acceleration (positive or negative) of .25G, the latter .35. What is a bit dangerous about it? In my book that is a normal aircraft operation.

3. Whether RAs are rare or frequent is airspace depended. In some places they occur as frequently as every 40 flight hours, in other every 2000. Simply: complex, congested airspace = more RAs.

Thanks .  MD has most annoying alerts that i know of .  Last 3 call was  Stick Shaker, Alternater, and Evacuation Signal

Hence the reason I said it could get a little dangerous, and why I didn't say it is an aerobatic maneuver.  Yes, if flown correctly, there will be very little cabin movement.  But with the amount of jet pilots out there, are you going to tell me that every one of them is going to fly it smoothely and slowly and nobody is going to overreact and start yanking on the stick?

That's true - some pilots overreact and fly RAs incorrectly. That's matter of proper training and professionalism. Any aircraft maneuver executed incorrectly may be dangerous.

Anyone know how I can actually download these and use them as ringtones? right now I only seem to have access through the website url in one of the previous posts, but I can't seem to find a way to download it directly onto my hard disk...

Interesting to hear these... Thanks, I can tell these are from the PMDG MD-11 because you can hear the echo unique to how PMDG recorded it.
