Is it possible to get a U.S PPL and IR (single engine), and later an Australian CPL (multi-engine vfr ) and do the Indian license conversion?
I dont see any reason why you should have any problems during the licence conversion ... HOWEVER ... you must understand that with the DGCA, anything that is other than the "norm" or the "routine", usually becomes dicey or trickey and sometimes problematic.
Will the DGCA accept licences and ratings from 2 different countries for indian cpl licence conversion (with ir). That is, if all my paper work- day and night checks, IR single engine check in the U.S and Multi-check in Australia are in order?
To play it safe, get the FAA PPL with IR converted to an Indian PPL.
Then get a written permission/NOC from the DGCA to do your remaining CPL and Multi engine training in Australia.
Once you have this NOC, you will not have problems during your conversions later on.
Is there any mention of how many multi ir hours are required for a multi-ir to be issued by the DGCA?
Multi Engine Rating requires 10 hours on a multi engine a/c registered and airworthy/available in India.
(DGCA has not defined what AVAILABLE means, but it is safe to get the rating on any one of those a/c listed on the DGCA website)
