RE: Quiz!
Didn’t Finnair take over Air Europes MD11 order? Does that mean Air Europe would have been the launch customer or had Finnair already received some examples by then?
RE: Quiz!
I’m getting bad at this. 10 questions and I only know the answer to question 4! I still enjoy them though!
RE: Wearing a wire
First time I heard it I thought the airframe was about to come apart!
RE: Wearing a wire
I was referring to the awful aerodynamic squeal during flap transit.
If the RJX had been a twin it would have been a whole new type requiring massive system changes. Annoyingly that would have made it much better!
RE: Pic Of The Day – The Majestic Maharajah!
747’s have normal size windows in the doors unlike other types which usually have fish eye lens viewing panes. These are used in an emergency for the crew to check outside for obstructions prior to opening the door and inflating the slide.
Unpainted parts of aircraft save huge amounts of weight and therefore reduce fuel burn. Some form of corrosion proofing is still required though.

RE: Wearing a wire
The original design was for 2 engines but at the time there wasn’t anything suitable according to their engineers so they looked at using four engines from the local toy shop. They claim that 4 engines is safer. This is an excuse of convenience as it is only really relevant to flight over large stretches of water which the 146 doesn’t do. 4 engines made the cost higher, causes a higher fuel burn, increases maintenance, increases the chance of going tech, makes the ergonomics and systems more complicated and doubles your chances of an engine failure!
If the 146 had been built using two decent western engines, simplified systems, better aerodynamics at the wing root during flap extension/retraction and better user ergonomics it could have been a much better tool.

RE: The people speak – no way BA!
Sorry, what I meant was the movement of aircraft from BACE to Eastern.
RE: Wearing a wire
The 146 is a glider with 5 APU’s 😉
RE: Wearing a wire
I’ve quite often seen new Boeing types under test trail a cable with a small cone on the back. When I used to do a lot of glider towing we experimented with placing a small kitchen funnel about 5 foot from the end of the rope as this aerodynamically stabilised the rope behind the tug after the glider had released. I have no idea what purpose it served for Boeings test engineers. There must have been far more satisfactory tests achievable for wake turbulence testing.

[updated:LAST EDITED ON 08-02-03 AT 07:48Â AM (GMT)]I heard that the whole Eastern deal was now off! …and that was from a BACE J41 pilot who has been told he will not be going to Eastern now, he will be put on an RJ course

[updated:LAST EDITED ON 07-02-03 AT 07:03Â PM (GMT)]Yes except those are a load of bull! The emf we are talking about the aircraft producing is very small and yet that is from several hundred tonnes travelling at nearly the speed of sound. A Ford Focus doing 80 on the motorway produces, in effect, nothing. The only time you get a static shock from your car is in certain weather conditions when you slide out across the seat made from acrylic fibres.
What those thngs that trail behind a car do is allow people who don’t understand the physics to think that they have found a solution so they are then convinced the problem has gone away. It is all psychosematic. It’s like when you were a kid and your mum kissed your injury better. It never did anything medically but somehow it seemed to make things better when you were the right age to believe it!
RE: Wearing a wire
Ren – the items you refer to are called static wicks. When a large piece of metal such as an aeroplane flies through the earths magnetic field it picks up a small enf (voltage). This voltage needs to be kept down as much as possible to avoid electrical problems with onboard equipment, etc. This is mainly done by using a number of discharge wicks situated towards the extremities of the aircraft. These trail the aircraft structure and allow some of the emf to discharge to the atmosphere. It isn’t 100% successful so the remainder is discharged through the tyres on touchdown (they have a metal in their compound to facilitate this). If this didn’t happen the first person to disembark would get a shock when they place their first foot outside!
RE: Wearing a wire
Kev – my apologies, I shouldn’t post after a long day at the office after an early start! It is my intention that one day people on this site will finally understand that the 146 is really just a low and slow 4 engined turd! After a very interesting conversation yesterday it was confimed to me that the 146 is flown much more like a turboprop than a jet. That explains why when a 146 pilot applies for a job with another company on a different type 146 time is frequently considered similar to turboprop time rather than jet time.

RE: Big and Beautiful from Budapest
I like 95% of it. I have never been keen on the black radome though.
RE: Wearing a wire
[updated:LAST EDITED ON 07-02-03 AT 10:17Â AM (GMT)]Yes there are a small myriad of tiny aerodynamic bumps on the fuselage that represent transmitters and receivers for the multitude of navigation and communications equipment.
Most aircraft that I can think of have just one fuselage so the word only usually gets used in the singular. I guess the place where that wouldn’t apply is in the maufacturers where they have a production line of fuselages. So yes, I would say the norm is to just stick an s on the end of the word. By the way occasionally the word fuselage is shortened to a slang version, fuzz, but I think it sounds a bit amateur.
One final thing, really really old 146’s had an aerial that had to be would out on a reel from the back end that trailed behind the aircraft by a few hundred feet! What a wonderful example of British engineering! It had to be wound out after take off and wound back in again before landing!!!
