PROCS FOR EGPWS USE INTO MDST ARPT.

Narrative

FLT MANUAL STATES THAT 'FLC'S ARE TO DISABLE EGPWS ON APCH TO STI.' I LOOKED IN THE A300 OPERATING MANUAL IN NORMALS AND EMERS AND COULD NOT FIND A NORMAL PROC FOR DEACTIVATING THE EGPWS. 1ST; SAFETY IS BEING COMPROMISED BY OPERATING INTO AN ARPT WITH KNOWN HIGH TERRAIN WITHOUT THE EGPWS; ESPECIALLY AT NIGHT OR IN IFR. 2ND; SINCE THERE IS NO NORMAL PROC FOR DEACTIVATING EGPWS; SOME PLTS MAY TURN OFF THE ENTIRE GPWS SYS IN ERROR. FINALLY; THE ISSUE OF EGPWS INTO STI IS NOT AN APCH; ONLY PROB. IT SHOULD REMAIN DEACTIVATED UNTIL PASSING 4000 FT ON DEP. THE FLT MANUAL 'MUST' BE AMENDED TO INCLUDE THE SPECIFIC INSTRUCTIONS FOR DEACTIVATING THE EGPWS AND WHEN IT SHOULD BE REACTIVATED ON DEP. THE TERRAIN AROUND THAT ARPT IS SERIOUS AND IT'S HARD TO UNDERSTAND HOW WE CAN BE OPERATING INTO IT WITHOUT HAVING IT SURVEYED BY CHK AIRMEN AND ENGINEERING TO ENSURE ADEQUATE SAFETY. DISABLING THE ONE THING THAT MIGHT PREVENT A HULL LOSS IS AN UNSAFE PROC. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR DISCUSSED PROCS IN AFFECT AND WAS CONCERNED WITH THE SAFETY OF FLT AND POSSIBLE CFIT WITH NO WARNING ABILITY. SUBSEQUENT TO HIS RPT; THE ACR HAS ISSUED NEW PROCS AND OBTAINED THE PROPER DATABASE FOR THE EGPWS COMPUTER.
