no offense intended.. just thought you should know how to get hold of these as a cpl/atpl.
if you are looking for "jungle jepps" for the countries mentioned try googling contacts for he following companies/organisations:
tanzania: Mission Aviation Fellowship Tanzania
zambia: Flying Doctor Service Zambia or Pro Flight
DRC: Mission Aviation Fellowship as well.
if it is charts you need is for major centers, you should be able to find it in the jepps... en route charts would be a bit hard to copy/ download.
i would seriously advise that you subscribe to jeppessen for a set of mannuals covering the area of your operation. if you are a commercial operator and fairly remote in location, it could be a struggle i guess. as a commercial operator, if professional, you should have updated jepp manuals. copy some charts out of a jepp mannual then to help you get through initially. you should be able to get airport charts from local authorities... guess it can be a struggle if you want to get it emailed/faxed.
pm me if you need more info. good luck!
