Avionics uses many different solder for different application: some of them
required for field repair without cleaning.  "do not use" may just apply to
one of the applications that can not use 331... unless you find out more
detail in the application notes or instruction (you might have to go all the
way back to the design files to find out the requirement), the best bet is
follow the instruction (use your spare time to find out why... it may take
longer than you thought... I ask someone went to a ware house to dig out 20
year old document before, just to varify a compatibility of a part that is
obsolete...).
my 1.72 cents.
