Guys,
I am sorry to inform you that the Zambian DCA requires 1000 hours PIC time after obtaining your non Zambian CPL-Instr rating, to obtain a validation.
Sorry to inform you about this, but what it comes down to is that you will probably need more than 1200 hours of flighttime in your logbook.
What Zambia is doing is actually implementing ICAO ruling.
I am a Dutchman and when I wanted to validate my FAA ATPL to a national Dutch CPL, the Dutch DCA also required 1000 hrs flighttime after obtaing my FAA CPL-Instr rating.
Good luck everyone, and keep in mind, there are still plenty African nations that still have not implemented this ICAO ruling.
