its a beat odd to be alert all the time and writing down every unknown abbreviation you here in the work environment , but it may deserve to do so to reach your goals in professionalism .

one of those abbreviations is MPD that I write it down today: 

Maintenance planning documents (MPDs) are provided by aircraft manufacturers to describe the repetitive tasks that are required to maintain their aircraft.


Maintenance planning engineers use the MPD information to develop operator maintenance programs (OMPs) that are then submitted to the relevant aviation authority for approval.

that was all ؛)
