Flaps 30/40 I understand. I'm referring to authorized flap settings only.
Now let me clarify. I'm not asking this as a pilot sitting in the airplane wondering why Boeing or my airline haven't given me performance numbers for certain settings.
I'm asking this as a person in the office writing out speed cards, etc, and wondering why Boeing haven't provided the information that is normally provided for every other aircraft of theirs I've worked with.
Also, I'm not even talking about a performance chart here, if you go back to my original question this was a question regarding the V-speed chart. Which will normally provide weights in excess of even MTOW on many aircraft (this is related to takeoff / performance computations when taking into account performance limiting MEL items). My only question has been why Boeing do not provide data on the 732 which I've seen provided in all their other FPPMs, or at least a statement of "NOT AUTHORIZED" or something to that effect. As I've, also, said they clam up (don't want to say) why this is, I suppose if we throw money at the problem it might solve itself, though I wanted to get some thoughts from the community as well, as I'm sure others more experienced than myself have done FPPM data work before.
In regards to the performance being so low it's impractical, that's really something that is an unknown until you've made the tables for a particular aircraft. In example, if I were to take two 727-223s today, which rolled out days apart from Boeing with the exact same configuration, and made performance tables for each you would find that their performance capabilities vary greatly in the exact same environmental conditions due to a number of factors. Long story short, one aircraft would be perfectly capable of doing a takeoff at MTOW off a 6000 foot runway with Flaps 30* (25) and meet climb performance limits, while the other aircraft would end up in the weeds and / or be unable to meet climb performance limits.
