Narrative:

On jan/tue/06 I worked at phl in the tower. The WX was terrible due to unusually warm WX causing a layer of fog that lasted in the area for more than a few days. During the afternoon the runway 9R approach lights (primary runway) failed. During this shift the lights came on intermittently. The harm caused to both the users/flying public as well as the controllers was astronomical. We tried switching to other runways; but rarely had the WX minima to shoot any approachs. We vectored aircraft needlessly waiting for the approach lights to return or the WX minima to increase. There are and will never be any procedures for this type of operation. We spent most of 8-10 hours holding and hoping to return to some sense of normalcy. It was not to be had during the evening shift and the chaos ended when all the arrs either diverted or canceled their flts.

Title: PHL TRACON CTLR DESCRIBED HECTIC TFC PERIOD DUE TO APCH LIGHTING FAILURE.

Narrative: ON JAN/TUE/06 I WORKED AT PHL IN THE TWR. THE WX WAS TERRIBLE DUE TO UNUSUALLY WARM WX CAUSING A LAYER OF FOG THAT LASTED IN THE AREA FOR MORE THAN A FEW DAYS. DURING THE AFTERNOON THE RWY 9R APCH LIGHTS (PRIMARY RWY) FAILED. DURING THIS SHIFT THE LIGHTS CAME ON INTERMITTENTLY. THE HARM CAUSED TO BOTH THE USERS/FLYING PUBLIC AS WELL AS THE CTLRS WAS ASTRONOMICAL. WE TRIED SWITCHING TO OTHER RWYS; BUT RARELY HAD THE WX MINIMA TO SHOOT ANY APCHS. WE VECTORED ACFT NEEDLESSLY WAITING FOR THE APCH LIGHTS TO RETURN OR THE WX MINIMA TO INCREASE. THERE ARE AND WILL NEVER BE ANY PROCS FOR THIS TYPE OF OP. WE SPENT MOST OF 8-10 HRS HOLDING AND HOPING TO RETURN TO SOME SENSE OF NORMALCY. IT WAS NOT TO BE HAD DURING THE EVENING SHIFT AND THE CHAOS ENDED WHEN ALL THE ARRS EITHER DIVERTED OR CANCELED THEIR FLTS.
