Totally agree w/ u on that one, Sci.
Nobody happier than me that it is not lawyers to write them down. ( even though you shouldnīt doubt itīs constructor company lawyers who review most of them in order to preserve companies from unnecesary responsabilities in unwanted cases. You should see some AIRBUS abn. ops. proc. headings ! ( sound more like legal warnings) )
Anyway, donīt wanna get way too far from the subject here, let me give another ref. here, just to get back on the thread ,
even though this oneīs got me completely puzzled ( big black hole in my knowledge most likely ).
It comes from the " ace the tech. pilot int. " book that most of all of us know way too well , therefore, canīt trust it much either. :
" there is NO critical gas turbine engine because the engines are positioned simetrically with opposing revolution direction "
Now Iīm lost.... ( opposing rev. direction?! . What has this got to do w/ a fan. Do we get assimetric blade effect out of a non-lift but THRUST producer such as a fan COMPRESSOR ? )
(Good to have this conversation.)
