Having also converted from Bus to 777 , here is my take.
All in all a very different experience. Kinda like soccer and rugby. Both ball games but quite different.
There are many differences but overall heres,s my impression ( some things may seen mundane but they are relevent when you are spending so much time on the flight deck.
What I dislike on the 777 predictably is no table or sidestick. Also the lighting to read charts etc is very poor compared to a bus.Also the seats believe it or not are very uncomfortable on the 777.( they say the guy who designed the seats on the 777,s wife was sleeping with a pilot)
For an aeroplane that was designed with the consultation of pilots I find this dissapointing.
I mean why should we have to struggle to read the charts sitting in discomfort !!! Also the audio speaker on the 777 is for some reason on the floor , so a little more difficult to hear , almost requiring full volume( for me ,compared to the bus) . Mr Bus put it more in line with where your ears are !!! The FMC is more instinctive on the bus although I am going to give Boeing a little latitude on this as I have been operating it for 4 months v 7 years on the bus. Allthough the use of multiple colours and a far more instinctive and faster thinking FMC does make me prefer the bus. Being able to string the alternate when doing diversion planning in the hold etc is a huge plus given modern fuel policies. Again I have to say I prefer the bus for its FMS.
Taxi with FBW on the bus is also like power steering versus a much heavier tiller on the 777. Again on that I prefer the bus.
OK so what do I like about the boeing then !
Well here is the crux. Where it counts , the abnormals ,Boeing is far superior, The Eicas and systems I feel are far simpler with more redundancy and a simpler overall pholosophy.
If it all goes pear shaped . I would prefer to handle the Boeing philosophy. With the only exception I find being engine failure on take off that is much busier on the 777 than the bus.
I also cannot see the need for having built in the need to trim the 777 just to comply with the requests of pilots. Truthfully the way most modern airlines automation policy , 90 % of the time crews hardly hand fly and trim anyway. So again while its more traditional to trim . I think Airbus got that right.
However on the bus the flight controlls demand roll rate ( a pain in a strong crosswind as you almost have to adjust then centre then adjust then centre) Its all a little messy. The 777 however the roll is aileron deflection ( bank) which is exactly what you want in strong winds.
I do prefer ( handling) the 777 , she is much more solid and stable in almost every regime.
I have found her lovely to land , however most airlines that operate both types seem to have many many more hard landings regularly on the 777 than on the Bus. I am trying to see why , but I do believe it has something to do with the Flare Law in the bus and probably related to motor skills on the sidestick being easier to replicate for regular flare ( inspite of what they say about looking out the window , assessing your sink rate etc which of course is primary.)
If Mr Boeing is listening please give us a more comfortable seat on the 787 , and much better lighting. Would,nt it be logical to have a light that actually shines on your approach charts !. Update your FMC , put in a faster processor. Keep the flight controll laws , but give us a sidestick and a table.
