RE: Etops 330, Any Progress?

Actually ETOPS 330 and LROPS are tied together. ETOPS 330 is merely a short hand for one of the changes that will result when LROPS rules are adopted. LROPS will replace the current ETOPS regulations. Allowable flight times from suitable alternates will be based on an airplane's total systems and eq...

RE: Etops 330, Any Progress?

The future of ETOPS 330 is tightly tied to the approval of LROPS that would put Twins, Tris and Quads on an equal footing for items not related to the number of engines, such as fuel reserve requirements, passenger oxygen and cargo fire suppression. As the rules stand now, Twins are held to a higher...

I don't think the -200ER's can carry much cargo with a full passenger load from Jakarta to Amsterdam and that's the direction that requires the capability.

RE: KLM Orders 2 More 777's

Perhaps KLM could be looking at the -200LR for the increase in cargo capability that would be available for some of their longer -200ER routes.

RE: Fuel Dumping

Landings at weights higher than 1.05*MLW are rather common for all air transport models, even those with fuel jettison systems, under emergency situations.

Most are returned to service after a structural (usually visual) inspection.

RE: Is This The Standard For Crew Rest On Airbus?

The A340 also has a crew rest that fits in the bulk cargo compartment.

The 747 and 777 have optional crew rest bunks above the passenger cabin, making use of this otherwise unused space and not displacing revenue cargo.

RE: Fuel Dumping

It's not true that a fuel jettison system is required if takeoff weight exceeds max. landing weight. <acronym title="Fargo - Hector International (FAR / KFAR), USA - North Dakota">FAR</acronym> 25.1001 says a jettison system is required if the climb requirements of 25.119 (Landing Climb) and 25.121(...

RE: Tristar Nose-up On Landing

The L1011 employed direct lift control on approach. This was done by raising the spoilers slightly, which required that the angle of attack be increased to maintain the same lift at a given airspeed. Spoiler angle could than be varied to control the airplane relative to the glideslope. If the airpla...

RE: EU "Airbus's Success Breeding Envy And Jealousy"

Thanks Leskova. It will be interesting to see what's out there and what can be gleaned.

PlaneSmart, one step at a time. First Airbus and then Boeing, although I'm unaware that Boeing has ever received re-payable government loans to fund new aircraft development.

RE: EU "Airbus's Success Breeding Envy And Jealousy"

Can anyone direct me to a source that would provide a record of the monies repaid by each Airbus airplane model for the EU launch aid loans? The terms for re-payment would also be of interest, i.e. how many airplanes had to be sold before re-payments began, what was the typical re-payment amount per...

RE: A-340 Performance Problems

Anxebla, The fire suppression requirements for Twins were established when ETOPS requirements were developed. Tri and Quads have never been required to have fire suppression matched to their potential diversion times. In that sense, the regulations for Tris/Quads have allowed a potentially greater c...

RE: 4 Engines 4 Long Haul?

As N328KF notes, the current 773ER MTOW is 775K lb. However, the A346 that comes closest to matching its Payload - Range is the 837.8K lb. MTOW version. However, this variant uses the 60K lb Trent 500. For overall airplane capability, absolute thrust isn't as important as Thrust to Weight ratio (T/W...

RE: China To Participate In Building The A350.

So Airbus has gone from describing the 7e7 as a "Chinese copy of the A330" to now saying the A350 is a Chinese built version of the A330?
