Yes I did have a good flight on CI903 yesterday.

Started off my trip from HKG-TPE on Saturday on their new B777 and was pleasantly surprised with an upgrade to premium business even for a short flight.

Sunday morning
My report was I was sitting in seat 31K, the front row of PE window seat(Sold as economy).
I did see about 50% of the passengers was on the plane for the same reason as myself.

Just sold out the night before.

PE seats were quite comfortable but being 183cms I would have liked the leg rest to go up a little higher as my feet still touched the floor at that angle.

Lighting was nice and air you could notice felt a little more natural.

Unfortunately no gifts or extras being a first flight.
Noticed now why I missed out on Business class as I was going through business class there were people who obviously take it very seriously (Hence it sold out in under 24hrs after confirming the first flight dates) and had books filled with notes and pictures of cabin flight crew and etc.

Not sure I would pay double for PE over economy as it was nicer but not that amazing. Up to about 130-140% above is okay for long flights.

I am not sure i felt the plane was quieter than other planes. But I was in the seat closest to the engine.
The engine looked impressive and a wonderful example of engineering (Being a civil engineer myself).

Noticed smoke coming out the bottom of the nacelle during taxiing, not so sure but is there an outlet down there?

I do have a video and pictures. Not good quality as its only from my phone. Which way is best to post it?

I will try tomorrow when I am at work which has a vpn. China its blocked.

Nice hearing from your experience!

Yes, that's normal, I've seen it in other videos of A350s and I know it's found on other engine types (I've certainly seen them on Trent 500s but can't remember if I've seen them on other engines)
I don't know what it does though but here's a close up of the outlet

We'd love to see pics

Probably the best way to share them would be to upload them on another website (like flickr if you have it or websites such as tinypic) then link/embed it in posts here.

Thanks for your report tris06, nice! Would love indeed to see pictures and videos!

I'm surprised you felt it noisy, my only and recent experience (B-LRD) was a smooth and very quiet cabin but I was seated more towards the back, could there be such a difference with a few rows in between?......

Also any water cannon oups at hkg?.............................................

I've had pheasant once. It was quite nice.

But if this one's endangered, keep it off the table and in the wild where it belongs.

This is the breather pipe and the drains mast combined …

Many of the bearings in a jet engine are sealed by the labyrinth seals which come up very close to the shafts without actually touching them. The bearing housings, gearboxes for the accessories (starter, fuel pump, hydraulic pump etc.) are fed with the pressurized bleed air, taken from the various compressor stages, blown across the narrow passages formed between the lands of the labyrinth seal and the shaft (the airtight cavity surrounding the bearing - airtight chamber). The end effect is a non-contact oil seal. This air is led back to the external gearbox by breather pipes, usually separated from the oil scavenge lines. This hot air with oil mist in it (discharged vapors) ends up in the air/oil centrifugal breather that is connected to the gearbox. This centrifuges out the oil and the hot air goes out through the drain mast. At idle speed, the centrifuge does not work as efficiently and the oil mist comes out the drains mast. Any oil that goes past the seal is burnt in the exhaust.

Otherwise, the RB211 engines has air operated VIGV (variable inlet guide vanes) and have no drains. The

Trent engines have fuel operated VSV (variable stator vanes), and the drain goes out through the aft drain mast, on th left hand side. The breather outlet on the

RB211 is on the side of the engine. The drain holes from the components are at the bottom of the engine.
The breather outlet on the

Trent engine is at the bottom. In this mast, four holes are incorporated, and that drain from backup generator (over-temp dump), drains collector tank, oil tank scupper, fuel pump pad, FMU (Fuel Metering Unit), VSVA (variable stator vane actuator), air oil heat exchanger, starter, hydraulic pump, backup generator drive cavity and IDG (Integrated Drive Generator).

On the Trent 500 engine, there is also a second drain mast at the aft bottom and this is for the fuel that is in the engine after a failure to start. All the fuel in the burner rails drains into the drain tank, but any fuel in the combustion chamber drains out of this core zone drain. Trent engines have a more efficient design of drains tank ejector pump than the RB211 engines. This returns the drains tank contents to the fuel feed system...
