Well put Avi8tor

I couldn't have said it better myself.

Dunno what these guys are on about carbon brakes not working when they are cold.

It might be the best turboprop ever built - the only problem is that it features too often on CNN and BBC news! Does not matter if it snaps your "head back into the head rest" during take-off - if passengers loose confidence in the type you are stuffed. No pax with snapping heads - no money for salaries!

Nugs - Eye checd da speling tihs time!!

Pilots (aircraft spotters, and other nerds, to a certain extend) yap about types. Passengers worry about one thing, and one thing only: PRICE. Newspapers may publish sensational articles, but the passengers are ruled by their wallets.

Thus it has always been, and thus it shall always be!!

That would imply that SAX is a 'low fare' operator?

Not so sure that the travelling public is quite so uncaring. I rememebr being very young and nobody would fly on Swissair or Iberia cause they had DC10's. 800 helped kill TWA.

I don't believe SAX is a LoCo operator as such, but the Q400 allows them to compete very aggressively when it comes to pricing - to the extend that on certain routes they have the ability to under price everyone else, and still make a bit of profit.

Yes
RTO is a straight line or should be. I was referring to the turn he made the nose gear steering failing then try and stop while the a/c is moving, RTO is worked out taking all factors in consideration and then the oomies with thick glasses come up with fig vs a specific weight. Carbon brakes do work better or More efficient if they have temperature in them

That fact is NOT in dispute

And that would require MORE brake energy than an RTO?

All depending where the steering failed and how close to the edge he was, taking turning radius into account and where on the runway the turn was initiated, for eg in the middle. With colder brakes he might for eg. need 5 meters to brake, taking thrust setting and weight and acceleration into account. With a warmer brake or brake at optimum , which will be achieved during brake application in the landing, ref. to the incident, he might need 3m to stop. If he was to close to the runway edge for the given scenario, he wouldn't be able to stop

You should be looking at this from another angle. The captain was able to turn the a/c using inside brake and bring it to a stop. Unfortunately he was not able to do it (within about 50cm) within the margins of the taxiway. The right main gear just went of the side of the taxiway with no damage to the a/c

.........until the recovery attempt.

That was my point in the beginning, don't judge and doom until all the facts are know. So a small thing turned into a big one and all the profs are giving there two scents worth

I give up too. Just be assured cold carbon brakes had no factor in this incident.

P.S. This is NOT a comment on the Crew performance.

SAS has all the old -400's they will therefore find all the problems and honestly the -400 is a lemon. Beancounters loves it because it sips fuel. Pilots hate it because its unforgiving and just keeps comming up with new problems. Heard a pilot say that he loved the simulator checks because there he had an idea of what would happen, in the air the plane would come up with something new all the time.
Interesting! It seems that the fun has only started!

When, and IF I fly on a -400, I will be very relieved if both main gears are extended, and remains extended during the landing roll.

Then their is the question about the COLD carbon brakes after we vacate the runway!!

Q400 Problems

Could there be any link between this and the Q400 problems SAS had earlier this year ?.

Am I correct in saying that the involved aircraft has been fixed? Seeing that SAX is having all 3 JNB-GRJ rotations on Q400s again, since yesterday (25/12)

In addition to my previous post...at the moment one of these aircraft is "Indefinately delayed" at GRJ again, landed sort of on-time from JNB earlier at around 15:00, but has not yet departed? Anybody got any info?
Like I said in the previous post, it seems that the one that did the ploughing job a few weeks ago only got back into service yesterday (christmas day).
