ERJ-170/190 autothrottles

[WMUSIGPI]

Yeah, the autothrottle system on the e-jet is definitely the "D student" of autothrottles. Not only do they hunt in gusty conditions, they tend to error to the low-side of Vap and slower, as opposed to varying at Vap to a somewhat higher speed. Its not very comfortable, so its best with the A/T off in gusty conditions.

They generally tend to lag, then over correct which creates a lot of nice cabin bumps at altitude when making speed changes if you don't help them.

Likewise, the aircraft is much easier to land with smoothness and precision with the A/T disengaged when landing flaps full.

The CRJ, what autothrottles, nuff said.
The Avro , it was rock solid for the most part. Procedure was for us to land with them shut off because we didn't have FAA authority for Cat III autoland (though it could do 3A no problem)

The auto-throttle on the embraer hold speed better than most pilots in my opiniono. They move a bit, but the biggest problem I've seen with them are pilots comfort level. A lot of guys can't stand to see them move and disconnect them or override them without ever giving them a chance. I've never seen autothrottles go wildly off speed, I can't say that for pilots. That's not to say I don't cover them to see what they are doing, but I wouldn't trade them for a non-auto throttle system.

170 auto throttles with gusty winds = not good
190 auto throttles with gusty winds = not to shabby

Ice speeds make for a nice smooth landing with the extra 10 knots....and please STOP overriding the throttles when they are at flight idle! Flight idle is NOT ground idle, the throttles sit forward of the stop detent in auto mode.
