Another great question about Autolands..........
Intruder is correct about the activation of the spoilers during landing in armed mode, or otherwise.
The reason for requiring the thrust levers to be at idle as well as having weight on wheels, before automatic activation of the speed brakes during landing, is that an aircraft may touch down (ie have positive weight on the wheels) during a normal missed approach. Obviously you would not want the spoilers to deploy in that scenario. If you were conducting a missed a approach, then the thrust would be increasing - so no activation of the spoilers.
The aircraft cannot activate reverse thrust without positive pilot input (except under extremely rare fault conditions in flight)
Aircraft generally require a great deal more pilot input than many people suspect

Keep flying, it's the only way to go.
Thanks to all for the replies.
Scarbag..
Great questions, and great answers from all..
Il chip in with my very limited knowledge.
Im sure you will have discovered it already being a bit of a fan of flight, but at live atc you can listen to various Air traffic control feeds from around the world including many in Australia..Some of it may sound like jibberish, but i think you'd enjoy it.
In Australia there is speed limit of 250 knots under the height of 10000 feet(Ive been trying to crack it in a cessna 172 but haven't quite got there
), but there may be occasions where for sequencing into an airport ATC may want to speed up or slow down a particular flight and this may be when you hear (or feel) them deploy speedbrakes(or apply power)among many other reasons for doing both that northbeach has covered beautifully..
Some aircraft dont like to "slow down and go down"Im sure northbeach could confirm that the 737 is one of those, and speedbrakes may be required just to keep to chosen or assigned speeds on descent or used to make sure you pass over a waypoint at an assigned time..
As far as thrust increasing it may just be that they are climbing to another height(Flight level) to see if they can find more favorable winds or less turbulence to improve the "ride" and whether you are flying a remote control airplane or an A380 if you want to climb you need to add power before you raise the nose or you will run out of speed and hence the ability to keep flying pretty quickly.
Again-all this was covered very well by others with far more knowledge than I!..
Enjoy.

Homesick Angel, great info.. thanks for your input.
Yep, I have been listening to Live ATC for a while now, and it is great...like you say a bit hard to follow at times but mostly I can follow the straight forward dialog. I dont want to stray too far from this probably worn out thread now..but, as far as ATC jargon goes, I have noticed that the Australian feeds that I listen to sometimes begin with, or end their transmission with G'Day..callsign, or callsign...G'Day. Does anyone know if this is just an Aussie thing..? I have heard pilots with foriegn accents say this as well..dont know if they are international flights or not. If it is an Aussie quirk, do other countries have their own style of ATC lingo?
Oh and good luck with your Cessna. I envy you..I think
Cheers

Strictly to the letter of the law were not supposed to do it, but in reality I doubt anyone is gonna get fried for it although i have seen threads on this site talking about it although i wouldn't be sure what to search for....
I have heard "cheers" as well on more than a few occasions and quite a number of other relaxed ways to sign on or off.I guess with everything being quite controlled and focused its nice to be a bit more laid back and human sometimes.I dont think it is strictly an Aussie thing to say Gday, but Id probably have to listen to a bit more of the other countries on ATC to find out.
Cheers
