Anybody have some good answers?
1. What are the limitations on the 747 with the loss of one yaw damper?
2. What is the reason for dihedral on the 747?
Normally one would think stability, but is it more to help gravity feed?
3. What are all the advantages of Wide chord fan blades?
I came up with FOD resistancy, stronger blades/less flex/no need for snubbers, better aerodynamic efficiency

Anybody? Somebody must know!!

No limits that I know of. Yaw damper #1 pwrd by #2 hyd, YD#2 pwrd by #3 hyd.
Keep the rest simple, your swimming way too deep. No harm in being familiar with 747 systems but you don't need to know them like your current jet.
I reccommend having a good understanding of
1. aerodynamics (stability, CoG vs CoP, , endurance v range,
2. performance (Vmcg through Mcrit, wet v dry,
3. weather (as relates to SW pacific, jet streams, turbulance,
Everything you can find on Cathay Pacific (what is the name of the airplane in the courtyard? hint; it's not Betsy)

Those were questions from my 1st interview. Just wanting to get them straight before the 2nd.

the wide chord blade is also lighter for it's size, since it is hollow (2 pieces of titanium sealed at the edges and then inflated like baloons in a mold to make the twisted shape on the RR blades) and therefore weighs less than a solid blade of the same size. though thiknking about this it's more an engineering benefit than operational.
