It's chapter 3 on the Boeing DC-9 tech manual website

http://www1.boeing.com/assocproducts/aircompat/dc9.htm

Added later: warning - this manual isn't suitable for operational purposes

This information is usually airline specific and we dont hand it out for legal reasons. We have absolutely no desire to end up in court after someone else has used our information...... Sorry.

Overrun you link points to the airport planning document, thats not the same as an airport analysis as it isnt airport specific.

Sorry Mutt - good point. The airport planning document is quite unsuited to planning or running an actual operational flight.

Its value is at the 'what-if' stage to accept or reject the obvious. Once that is sorted out then one spends the money for a performance engineer to do the specific airport performance analyses. I must say that we do it that way for airport planning and design purposes as well. Since the runway and associated works cost anything from $US5,000 to $US50,000 per linear metre, a performance engineer is money well spent.

... did someone say performance engineer ? ... may I offer the Mutt and John show ... we are noted for our fine tapdance routines ......

Following on from OverRun's comment on runway cost, it is not at all uncommon for a major airline user of a smaller airport to be involved in planning workup based on specific runway analyses. I recall one Australian airport where a proposal to extend a runway was canned on the based of performance calculations showing an inadequate return to the airline which, in turn, then didn't want to have to pay more in charges for a white elephant.

The planning data has a lot of practical limitations but does provide good ROM data for preliminary airport planning purposes.

... or, if you have the AFM .. then you have the basic data to do the calcs yourself ..
