Air Traffic Incident | Pilot Deviation |
Narrative:
Level at 8000 ft we were tracking the localizer runway 30L sjc. Approximately 24 mi southeast of the airport. Traffic was pointed out to us at 10-11 O'clock position as we were cleared to cross klide at 5000 ft. Traffic was spotted on TCASII, 2200 ft below us at 11 O'clock position. Because the traffic was a concern, the descent to cross klide was at 500 FPM until we were clear of the traffic. We never saw the traffic nor did we receive a TA on the TCASII. However, based on TCASII information the crossing at klide was at 5600 ft. The controller said nothing and only after returning to my home did I consider this an issue. I should have informed the controller that we were going to be higher at klide because of the traffic.

Title: ACR DELAYS DSCNT BECAUSE OF RPTED TFC TOO LONG AND IS UNABLE TO MAKE XING RESTR.
Narrative: LEVEL AT 8000 FT WE WERE TRACKING THE LOC RWY 30L SJC. APPROX 24 MI SE OF THE ARPT. TFC WAS POINTED OUT TO US AT 10-11 O'CLOCK POS AS WE WERE CLRED TO CROSS KLIDE AT 5000 FT. TFC WAS SPOTTED ON TCASII, 2200 FT BELOW US AT 11 O'CLOCK POS. BECAUSE THE TFC WAS A CONCERN, THE DSCNT TO CROSS KLIDE WAS AT 500 FPM UNTIL WE WERE CLR OF THE TFC. WE NEVER SAW THE TFC NOR DID WE RECEIVE A TA ON THE TCASII. HOWEVER, BASED ON TCASII INFO THE XING AT KLIDE WAS AT 5600 FT. THE CTLR SAID NOTHING AND ONLY AFTER RETURNING TO MY HOME DID I CONSIDER THIS AN ISSUE. I SHOULD HAVE INFORMED THE CTLR THAT WE WERE GOING TO BE HIGHER AT KLIDE BECAUSE OF THE TFC.
