i give up!
Could you please help with interpretation of following IOSA requirement?
FLT 1.11.3 The Operator should have a process to ensure data or products acquired from external suppliers (other than electronic navigation data products, as specified in FLT 1.11.4), which directly affect the safety of flight operations, meet required technical specifications prior to being utilised in the conduct of operations.
What can be considered as data or products from external suppliers? To me it seems it can be basically everything not produced in house - NOTAM, Meteo info, Flight plan data (waypoints etc.), takeoff performance calculation data and some more I guess...
and how detailed it should be described or it might be enough with few statements in OM ? how did you solve this? (I hope somebody did! )
