A C172 LOW TIME CFI RPTED THAT HE AND A STUDENT WERE REPRIMANDED FOR PERFORMING THE FULL APCH AT MGJ IN N90'S AIRSPACE.

Narrative

WHILE ON AN IFR FLT PLAN WITH AN INST STUDENT; WE HAD A MISUNDERSTANDING OF COM WITH A NEW YORK APCH CTLR. WE WERE BTWN THE INTXNS OF CRANK AND SHAFF ON V213; AS FILED; ON OUR WAY TO DO A PRACTICE ILS AT MGJ. AT THIS POINT; THE CTLR SAID WE WOULD PROCEED DIRECT TO DIYAD AND THAT WE WERE CLRED FOR THE APCH. I HAD THE STUDENT MAINTAIN 3000 FT AND PROCEEDED TO DIYAD AS AN IAF. WHILE AT THIS ALT; AND 1 MI OR SO FROM DIYAD; THE CTLR HAD US SWITCH TO CTAF. AFTER XING DIYAD; WE COMMENCED PERFORMING THE FULL PROC. WHILE WE WERE ON THE PROC TURN INBOUND; ANOTHER ACFT ON CTAF INFORMED US THAT NEW YORK APCH WOULD LIKE TO SPEAK TO US RETURNING TO THE NEW YORK APCH FREQ; THE CTLR REPRIMANDED US FOR DOING THE FULL PROC AFTER HAVING BEEN CLRED FOR THE APCH EARLIER. MY CONFUSION IS THIS: 1) WE WERE NOT GIVEN A HDG TO INTERCEPT THE LOC WHEN WE WERE GIVEN CLRNC TO GO DIRECT DIYAD; 2) THERE WERE 2 OTHER; MORE LOGICAL INTXNS AT WHICH WE COULD HAVE INTERCEPTED THE LOC BTWN US AND DIYAD WHILE ON V213 (JOYST AND NISSN); 3) WE WERE NOT GIVEN VECTORS TO GET ESTABLISHED ON COURSE AHEAD OF THE OM (DIYAD). IN THE FUTURE; I WILL ASK THE CTLR FOR CLARIFICATION; OR REQUEST SPECIFICALLY THAT WE WOULD LIKE THE FULL PROC.
