APCH CTLR TRIES TO REDESIGN AN NDB APCH.

Narrative

DURING AN IFR TRAINING FLT ON AN IFR FLT PLAN AND CLRNC; I WAS RECEIVING DUAL INSTRUCTION FOR AN ADDITIONAL CLASS RATING (AMEL). WE PROCEEDED FROM BFI VIA VECTORS TO THE GRAYE LOM/NDB. BEFORE ARRIVING AT THE NDB; WE WERE 'CLRED FOR THE NDB 35' APCH; BUT GIVEN A RESTR TO REMAIN 'N OF I-5.' WITH A WIND FROM THE N; THIS IS IMPOSSIBLE; AS THERE IS INSUFFICIENT TIME TO GET ESTABLISHED OUTBOUND; AND THEN COMPLETE A COURSE REVERSAL (EITHER A 90/270 OR PROC TURN) AND COMPLY WITH SUCH A RESTR (WHICH IS APPARENTLY TO KEEP ACFT CLR OF AN MOA). THIS APCH SHOULD BE OTS IF SUCH A RESTR IS REQUIRED; AND WINDS ALOFT ARE FROM THE N. A VISUAL RESTR ('N OF I-5') IS ALSO INAPPROPRIATE ON AN INST APCH. AS I WAS WEARING A VIEW LIMITING DEVICE; THERE WAS NO WAY FOR ME TO COMPLY; AND THE PIC INSTRUCTOR IN THE R SEAT DOES NOT HAVE A CLR VIEW TO THE L TO SEE THE GND REF. FURTHER 'I-5' IS CLRLY AN AMBIGUOUS INSTRUCTION IN AN URBAN ENVIRONMENT -- TFC SIGNS UNREADABLE FROM 3000 FT. A R-HANDED APCH PROC TURN WOULD BE REQUIRED TO COMPLY WITH THE RESTR; BUT WOULD RESULT IN INTERCEPT OF THE INBOUND COURSE INSIDE THE NDB. THIS WAS SUGGESTED BY THE CTLR; BUT IS INAPPROPRIATE IF THE NDB APCH IS TO BE CONTINUED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR INDICATED THAT THE CTLR APPEARED TO BE TRYING TO ACCOMMODATE THE TRAINING FLT AND THAT IT WAS TO HIS CREDIT THAT HE WAS. HE ALSO SAID THAT THE RESTRS WERE GIVEN LATE IN THE APCH AND THERE WAS NO TIME FOR ANY ADVANCE APCH PLANNING. THE INSTRUCTOR INVOLVED INDICATED THAT HE HAD NEVER BEEN GIVEN THIS TYPE OF RESTR FOR THIS PARTICULAR APCH; BUT THAT HE DOES NOT ROUTINELY USE IT BECAUSE OF THE PROX TO THE RESTR AIRSPACE AND DISTANCE FROM THE HOME FIELD. IN CONVERSATION AFTER THE FACT; THE RPTR WAS TOLD BY A DESIGNATED EXAMINER THAT HE WOULD HAVE TAKEN THE CLRNC AND MADE IT WORK WITH STEEP TURNS AND A 90/270 DEG TURN. THIS CAUSES THE RPTR AND THE ANALYST SOME CONCERN.
