CPR PLT COMPLAINS OF ATC PROC IN FLT PLAN HANDLING.

Narrative

I DON'T BELIEVE ATC PERSONNEL ARE QUITE CLR OR KNOWLEDGEABLE ABOUT THE DIFFERENT TYPE OF RNAV UNITS THAT ARE INSTALLED IN ACFT. EXAMPLES VOR-DME-LORAN-LAT LONG ETC. FOR THE CTLR TO KNOW WHAT SYS IS BEING USED BY THE PLT IS IMPORTANT TO BOTH. IN MY CASE ON A FLT FROM MCO; TO MVN WITH A FUEL STOP AT PDK I WAS ISSUED A CLRNC I COULD NOT ACCOMPLISH WITH MY RNAV SYS. (VOR/DME AND LORAN). OUR IS MCO. I WAS GIVEN RADAR VECTORS TO V267-VNA 142/018 DIRECT (FILED AS AN INTERMEDIATE POINT AT REQUEST OF FSS). JAX PROBABLY FIGURED I COULD TO JVC DIRECT VNA 142/018. WITH MY EQUIP I CAN'T DO THIS WITHOUT DRAWING A LINE IN A CROWDED COCKPIT AND SETTING WAY POINTS. VERY DIFFICULT. ALSO; OFF OF PDK I WAS GIVEN A LAT-LONG IN MY CLRNC WHICH I COULDN'T ACCEPT. INSTEAD OF AN ALL INCLUSIVE RNAV DESIGNATOR; DIFFERENT LETTERS SHOULD BE ASSIGNED TO DIFFERENT RNAV SYSTEMS JUST AS 1A-1B-1D AND SO ON. MY POINT BEING IF ATC KNEW THE SYS AVAILABLE TO THE PLT THINGS WOULD GO MUCH SMOOTHER. BY THE WAY I HAVE SUGGESTED THIS TO FAA MANY TIMES. THEY DIDN'T BOTHER TO REPLY.
