Narrative:

While on intercept heading for approach to cdg ILS runway 27 (240 degree heading), TCASII gave traffic at approximately 20 degrees left relative bearing 3 mi. The TA changed to an RA with the following sequence as I recall (see graphic). We did hear 'clear of conflict' after RA's. After the incident tower said there was no traffic except an aircraft on the ground with its transponder on. Reason for report: cleared to 4000 ft, at 5200 ft we get an RA, altimeters were not set to 999 hc psc till level at 4000 ft, this is approximately 3600 ft (400 ft low). Altimeters were not caught until after the priority 1 problem of a midair. Suggest: get the folks who wrote the regulations into the air and let them experience the asininity of low transition levels and altitudes.

Title: ACFT INBOUND TO CDG ON RADAR VECTOR HAD TCASII TA RA AND OVERSHOT ASSIGNED ALT.

Narrative: WHILE ON INTERCEPT HDG FOR APCH TO CDG ILS RWY 27 (240 DEG HDG), TCASII GAVE TFC AT APPROX 20 DEGS L RELATIVE BEARING 3 MI. THE TA CHANGED TO AN RA WITH THE FOLLOWING SEQUENCE AS I RECALL (SEE GRAPHIC). WE DID HEAR 'CLR OF CONFLICT' AFTER RA'S. AFTER THE INCIDENT TWR SAID THERE WAS NO TFC EXCEPT AN ACFT ON THE GND WITH ITS XPONDER ON. REASON FOR RPT: CLRED TO 4000 FT, AT 5200 FT WE GET AN RA, ALTIMETERS WERE NOT SET TO 999 HC PSC TILL LEVEL AT 4000 FT, THIS IS APPROX 3600 FT (400 FT LOW). ALTIMETERS WERE NOT CAUGHT UNTIL AFTER THE PRIORITY 1 PROB OF A MIDAIR. SUGGEST: GET THE FOLKS WHO WROTE THE REGS INTO THE AIR AND LET THEM EXPERIENCE THE ASININITY OF LOW TRANSITION LEVELS AND ALTS.
