G5 Autothrottle question

[semperfido]

How about those suction toilets?

Just some food for thought....

The 121 outfits have been flying with this type of automation for a VERY long time...auto-brakes, auto-spoilers, auto-land, fully integrated FMC's with auto-thrust, etc...

With that being said, their flight-crew SOP's have matured pretty well. And I can recall some specific COM procedures with respect to mixing and matching certain levels of automation in the interest of the highest level of safety, and so crews wouldn't make stuff up along the way.

I can dig some of that stuff up if folks are interested. But a post over at the majors board asking some questions might get you some pretty good info, as they've been flying this stuff longer than anyone.

Do you have "steam guages" in your GIV/GV, or did you adapt to glass?

I adapt to stuff that WORKS. I don't adapt to stuff that presents a potential safety issue. Auto-retard does IMO.

As for the suction toilets, they're great as long as you don't bump the button while you're sitting on them

Get in the sim and do some auto-lands.

Then try to do them with the AT's inop with CAT III C wx.

We don't have auto land. Still CAT 1 mins although EVS will get you to 100 AGL if you get the lights in the HUD.

Autothrottles

If they're that bad then maybe you should have maintenance figure out what the problem is. All in all, the autothrottles work fairly well in our two airplanes. I'm a believer in flying the airplanes the way they were designed to be flown. I also fly a Falcon 2000 with no autothrottles so should I leave them off in the GV for consistency? So I don't forget what airplane I'm in....come on now.

Watch 8 or 10 people land 1500 feet long because of the auto-retard feature and get back to me. Not talking about auto-throttles. We're talking about 50' AGL auto-retard. Big difference.

The EGPWS (call outs) and the A/T system both use the Rad Alt, but the EGPWS does not tell the A/T system to pull back to idle. If the a/c detects landing config than the RAD ALT is whats telling the A/Ts to pull back so I would suspect the RAD ALT system. You can test them both and make sure they go to 100 ft + - 5 ft ( they should be at -5 ft on the ground) also I think that the A/T system is using the RAD ALT that is selected on the pilots Display controller so you could try flying with #2 RAD ALT selected. If that does not work try Boxing the #2 A/T computer. Has for the 5000 ft runway I don't understand how that would effect it. I hope this helps.

So you're crossing the threshold at Vref, and the throttles aren't starting towards idle at 50', causing "your pilots" to float 1500' down the runway? If they don't, write them up, and if they do,................well there's another problem, unrelated to autothrottles.

Let's just say, the auto-throttles work as advertised. I just don't like the commercial.


(Kind of like that dorky SWA commercial with the F/O and a guitar...)
