Embraer e190
 

Got a few questions about the 190! When landing why do i see the throttles trying to retard to idle and the captain keeps pushing them up? Are these autothrottles and you have to push them up to stay on vref? Can you turn this function off? On a normal day when do you typically wipe the power for landing? What is that black lever on the right with the gold button? Is that so you can pop the window open on the ground? How different is the 175 compared to the 190? Is it mostly limitations differences and everything else is the same? Thanks guys!

The auto throttles will pull power in landing so most guys override them to control when they want idle.

I pull the power around 30' or even closer to 50' if my ref is high. It all depends on my energy. As soon as I'm getting close to the ground and feel like I've got plenty of energy, the power comes out. On a side note, I (and many others) don't use the auto throttles on approach/landing. We usually click them off at some point on approach. They can lag and don't typically mirror what id like them to be doing.

Yes, its how you open the window. Push the gold button, pull the handle.

Let me preface by saying I currently have less than 100 hours in the plane.

In any wind gusts, and sometimes in calm wind, it seems like the lagging throttles create a bracketing effect. This causes speed to vary quite a bit on short final so pilots tend to limit the retard function until they are ready. Don't want to be ten knots slow at 100 feet. From my limited experience I've had better landings with them off. Not that they are horrible, just that I'm more in tune with my speed and energy state. Flare at 20-30 feet and wipe the power at ten if you haven't already is what I'm told. Can't change how the auto throttles function but you can turn 'em off.

Haven't flown other ejets, but guys I know have said that the systems are all very much the same, just different numbers.

Having flown both the 170/190 for 7 years and 2 different companies, I have to disagree with that statement. The vast majority leave the A/T engaged.

People override the A/T logic as a landing technique and to compensate for wind gusts. Once again, the majority don't engage in the practice of adding power at 20-30 feet.

Standby Magnetic Compass not valid while transmitting on VHF #1.

Saw this in my study guide. Anybody know why and what a compass has to do with a radio?

I would assume that while you're transmitting on #1 you're creating enough electrical interference to cause the standby compass to give erroneous readings.

I'm not sure what the E190's radios specs are but a typical King KX radio will transmit at 10 watts and 6 amps of power and will receive at less than 1 watt and less than 1 amp; that's considerably less.
