Narrative

DURING A REVENUE FLT THE CAPT ADVISED ME THAT THE FAMILY OF A COMPANY PLT WAS ONBOARD. WHEN THE FLT ATTENDANT CALLED THE COCKPIT; HE TOLD HER TO SEND ONE OF THE FAMILY MEMBERS TO THE COCKPIT. SHE (AND I) QUESTIONED THIS SEVERAL TIMES; BUT HE INSISTED. SINCE BOTH THE FARS AND COMPANY POLICY ARE QUITE CLR THAT THE CAPT IS THE FINAL AUTH DURING FLT TIME; THE FLT ATTENDANT COMPLIED WITH HIS INSTRUCTION. THE PAX THEN REMAINED IN THE JUMPSEAT UNTIL LNDG. I DON'T FEEL SAFETY WAS COMPROMISED; BUT THIS IS JUST ONE MORE EXAMPLE WHERE THE CREW CAN SUGGEST OR ADVOCATE THEIR POS; BUT ULTIMATELY THE CAPT WILL DO AS HE WISHES AND THE FARS DON'T GIVE THE FO ANY AUTH TO COUNTERACT A QUESTIONABLE DECISION. THE ENTIRE FLC IS ALWAYS HELD RESPONSIBLE FOR EVERYTHING THAT HAPPENS DURING FLT; BUT THE ENTIRE FLC IS NOT GIVEN APPROPRIATE AUTH TO EFFECT A CHANGE UPON WHAT HAPPENS DURING FLT. IT IS MY OPINION THAT SAFETY WOULD BE GREATLY ENHANCED IF DURING CRM; THIS ISSUE WERE GIVEN A GREAT DEAL MORE ATTN; PARTICULARLY AMONG THE OLDER CAPTS. SUPPLEMENTAL INFO FROM ACN 340437: UPON LNDG 2 PAX WAITED FOR EVERYONE TO DEPLANE AND THEN THEY APCHED ME. THE WOMAN STATED; 'ISN'T WHAT JUST HAPPENED HERE AGAINST FARS?' I ASKED HER WHAT SHE MEANT. SHE MOTIONED TOWARD THE COCKPIT AND SAID 'LETTING THAT BOY IN THE COCKPIT FOR LNDG?' I SAID THAT IT WAS THE CAPT'S AUTH AS TO WHO WAS UP THERE. SHE THEN SAID; 'NO; IT'S YOUR RESPONSIBILITY TO UPHOLD THE REGS IN THE CABIN.' I ANSWERED HER WITH AGAIN; THAT THE CAPT IS THE FINAL AUTH AND I WAS DOING WHAT I WAS TOLD. EVEN WHEN I KNEW IT WAS AGAINST REGS I WAS FOLLOWING THE CAPT'S AUTH. IT STATES THIS IN OUR MANUAL!
