on a clear day, the view from a Dash 8 is better since its cruising at lower altitude. On a bumpy day its more like a ride you pay big money for at places like Movieworld.

Speaking of which... (apologies for the thread drift)...

What is the typical flight level for the 737? Yesterday returning from MEL I felt like I was getting a bit of a headache. The captain announced a little later that we were cruising at 39,000 feet, which seemed higher than I remember for most flights (30-35K). Anyway, after we began our descent into SYD the headache went away.

Maybe I'm just crazy? Don't answer that last question! :mrgreen:

Canberrans - get excited!!
The big diff between the 300 and 400 is that the 400 has the most annoying pop music playing before engine start.

I flew to BDB this week on a 300 and returned from ROK on a 400 and found the 400 somewhat quieter - but I was in row 3 and further away from the props. There was a significant blustery wind on the ground in ROK but it didn't provide any turbulence when airborne, so the 400 is somewhat more stable in those conditions.

Geez why so much fuss about a few bumps? At least DH8 or Q400 are reasonable size a/c. When flying a smaller a/c (every seat is both window and aisle) on a stormy day on a route getting towards the limit of its range, that's when things get interesting.

Speaking of stormy. Seem to be having a run of them every time I fly domestically. At least tomorrow I'll be on something bigger, 737, but once again the forecast is for gales and thunderstorms.
 
Transform your lounge room (or any indoor space) into your own private movie theatre in just a few seconds.

Our Mini Pocket Projector is small, light and easily transportable. A must have!

39000ft is pretty standard. The NGs fly higher than the classics (and hopefully you were in a red NG not a white classic!) I don't know what if any cabin pressure difference there would be, but given you're a regular flyer on us, I reckon you've been at 39000 plenty of times before.
cheers

PS I'm the crazy one!

Yep, it was definitely a red NG... DJ865, my favourite time to depart MEL, often after arriving at the Lounge around 4:00pm for a very late lunch! Hey, that Thai pumpkin soup they had on yesterday is quite nice. :D

BTW I still haven't been on a live2air flight. :(

The operating ceiling for 737NG is 41,000 feet. At full takeoff weight, it will need to step up to that max ceiling, starting around 31,000.

The 737-100 and 737-200 had operating ceiling of 35,000 feet, which was increased to 37,000 feet with the 737-200 Advanced model. This was matched by the 737-300/400 "Classic" versions.

The 737NG has a cabin altitude of 8,000 feet. So depending on the operation of the cabin control system, that cabin altitude can be reached earlier than the operating ceiling and the pressure differential then increases with altitude, or it can be set to operate with constant pressure differential and hence the cabin altitude will climb with cruise altitude up to the maximum of 8,000 feet at 41,000 feet. I don't know how Qantas operates their 737 cabin environmental control system.

But either way, 8,000 feet should not cause discomfort for passengers unless they are particularly sensitive to altitude. By way of comparison, the north rim of the Grand Canyon is 9,000 feet above sea level.

And just for interest sake, the BBJ version of the 737NG has a modification available for a 6,500 feet maximum cabin altitude, through the operation of higher pressure differential. Commercial operators are unlikely to seek this modification for their fleets due to the increased maintenance costs associated with the cycling of high pressure differentials.

That's probably me. On an international flight (e.g. in a 744), more than a few glasses of red wine is enough to consistently trigger a bad headache. I can drink almost a bottle at home and still be at my best. Well, at least from my perspective. Mrs YY thinks otherwise. :oops:

yep.. been there, done that.. In fact lately it has been about 3 glasses before the headache starts. 'preventitive panadol' seems to work well. Either taken in the lounge or at the first sign of any headache. And for those really bad headaches, panadeine... Oh yes, and then there's always the recommendation of drinking lots of water and less wine (probably the better of the choices but not nearly as nice ;) )

Been up there before in the 737 - as the captain described it - "a rather lofty 41,000 feet".

Yes, I've popped the pills, although sometimes I've had to resort to proper medication (e.g. imigran).

I agree, it is hard to refuse, especially when they are bringing around wine you haven't tried before such as the nice French liquid on SQ!
