Does anyone know what the story was with the most recent dual flameout over Florida? That one got kind of pushed up under the rug!
 
It's not pushed under the rug, it's on the NTSB website as under investigation. Company has a new procedure for boost pumps and engine anti-ice on at TOD. NTSB said to be concentrating on environmental factors, not fuel.

So you are telling me that the engine heats come on at TOD no matter what the conditions???? If that is so, it sounds like a knee jerk reaction of the first order??? How is that going to help anything if you are flying along in clear air??? Or is there more to the story?????
 
funny thing is the engine heats are only suppose to be put on below 90%n1, and at cruise your above 90%n1, so you have to pull back the power to turn on the heats. And in both glider incidents the motors quit at throttle retard.

RNO,

Good assesment, "knee-jerk" is the tradional Flight Options reaction, and yes, EVERY TOD when above FL300 for more than 30 mins is what the mandate says. I can't say it hurts to put the boost pumps on, or the ignitors for that matter. So besides burning up more ignitors I guess it's no skin off my back.

=why would you pull the throttles back to idle anyway just to put on engine heat?

Not back to idle, limitation of the BJ is to have the power at 90% N1 or less before turning engine anti-ice on. It protects the barrier layer of air inside the burner can that insulates really hot fire from the metal of the combustion chamber. If the anti-ice is turned on with the power high it can disrupt the air boundary due to more bleed air leaving the engine.

I have way too many hours in this lovely little pile of crap airplane and I'm racking my brain to figure out why in heck you would turn the engine heats on to desend if you were in clear air for say the last 30mins. It makes no sense what so ever, and if someone at Options would actually think it through, I'm sure it would make no sense.

Now the boost pumps??? Ok, maybe they think that is going to help the fuel keep flowing, I will give them that. Even though those pumps aren't strong enough to keep the engine running by themselves.

Please understand 411 I'm not berating you in any way, I fly the silly thing and anything to keep this thing from becoming a glider is good info. However after reading what their cure is, I'm not sure they know anything about the jet....

Someone read Raytheon, needs to come up with a fix before this jet kills someone. Note to Raytheon FUEL HEATERS. I'm not suprised the engineers there can't figure this one out. After seeing some of the brillant fixes they came up with in the past for this thing.

God, I need to fly a different jet.....
 
RNO,

I didn't take offense to anything you said, no worries. Most of our pilots share the same feelings as you, I was just saying that if THAT'S what they want me to do, I'l humor them. Yes, they still want them to be on at TOD even if you've been in clear air, but I think that's just to make it the same way every time so there's no thought involved. We have to play to the lowest common denominator you know? I think they're smart enough to know you need moisture present to create ice, the verdict is out though.

I have heard different versions of the latest flameout story, some that say they were in clear air, others that say they were on top of most of the weather but in the wispy cirrus on top. If this was the case then it is possible they got some induction ice and the "pop" they heard from each engine was a turbine coming to an abrupt stop. As per the new procedure we are also supposed to have the heats (engine) on for operation at altitude in the wispy stuff even if it's -60 C out.

"It's never too cold for ice" is their new mantra. I'm going to wait till I see something stamped by NASA to finally judge that statement. It is odd though that in the same geographical area that day there were 5 jet engines that flamed out. What I heard from several sources that would be in the know at CGF said there were 3 717's that had single flameouts and our dual makes 5.

And as dime said, the latest word is RTN and PWC are looking into heaters for the Emperor's airplane but wouldn't be ready till late 2006 and not for the whole fleet till 2007 sometime.

Yall can laugh...but I am gonna say it again...METHANE pocket. As low as .95% concentration in the air will shut down a radial engine...that is LESS THAN 1% concentration. This area of the world has been proven to have large escapes of methane from the Atlantic seafloor and then leave the surface of the ocean and rise through the atmosphere. This ain't no conspiracy theory here....You see if you can find any reason why those other engines shutdown...and the two engines on this Beechjet. Think about the probabilities that 5 turbine engines are gonna shut down in this small of a geographic area, on ONE DAY, within ONE HOUR. Now if you think there wasn't a factor outside of the planes....you probably spend a LOT of money on the lottery.
 
Methane? Isn't methane flammable? (or "inflammable")
So instead of a flame out, you should get the big bang of the airways?
