Narrative:

During climb out, I noticed that the oil temperature gauge remained pegged. Strange, since this is florida in summer. Called tower to return to field. Told to report 2 mi right base. I had a young passenger and did not want to take any chances. Due to traffic, tower then vectored me away from airport. I refused and declared an emergency. I was cleared to land and after landing, asked to call the tower supervisor. She was unhappy that her tower person had to redirct 5 or 6 planes for me. To her I say 'too bad!' fortunately, the problem was a faulty gauge and not an oil problem, but I did not know that until I was on the ground and the aircraft custodian checked things out for me. She didn't think a faulty gauge warranted more than a precautionary landing. I see her point (I could have mentioned the problem at my first call) but all in all, I would do the same thing again -- except sooner!

Title: RETURN LAND AND EMER TFC STATUS QUESTIONED BY TWR SUPVR WHEN EMER DECLARED BY PLT IN A C172 WITH THE OIL TEMP INDICATOR PEGGED ON DEP FROM FPR, FL.

Narrative: DURING CLBOUT, I NOTICED THAT THE OIL TEMP GAUGE REMAINED PEGGED. STRANGE, SINCE THIS IS FLORIDA IN SUMMER. CALLED TWR TO RETURN TO FIELD. TOLD TO RPT 2 MI R BASE. I HAD A YOUNG PAX AND DID NOT WANT TO TAKE ANY CHANCES. DUE TO TFC, TWR THEN VECTORED ME AWAY FROM ARPT. I REFUSED AND DECLARED AN EMER. I WAS CLRED TO LAND AND AFTER LNDG, ASKED TO CALL THE TWR SUPVR. SHE WAS UNHAPPY THAT HER TWR PERSON HAD TO REDIRCT 5 OR 6 PLANES FOR ME. TO HER I SAY 'TOO BAD!' FORTUNATELY, THE PROB WAS A FAULTY GAUGE AND NOT AN OIL PROB, BUT I DID NOT KNOW THAT UNTIL I WAS ON THE GND AND THE ACFT CUSTODIAN CHKED THINGS OUT FOR ME. SHE DIDN'T THINK A FAULTY GAUGE WARRANTED MORE THAN A PRECAUTIONARY LNDG. I SEE HER POINT (I COULD HAVE MENTIONED THE PROB AT MY FIRST CALL) BUT ALL IN ALL, I WOULD DO THE SAME THING AGAIN -- EXCEPT SOONER!
