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...Jump to post
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...Jump to post
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(...Jump to post
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...Jump to post
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.
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...Jump to post
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...Jump to post
I think it's the lack of a comprehensive set of specifications rather than lack of a picture that are creating the skepticism. Can anyone provide a set of typical airplane characteristics (MTOW, OEW, Engine <acronym title="President Airlines (Cambodia)">TO</acronym> Thrust, TOFL, Airplane Dimensions...Jump to post
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...Jump to post
