Narrative:

Altitude. First officer flying. Checked in with cdg approach, leaving FL160 for FL110. Reply: 'air carrier X maintain FL110, direct crueil.' first officer thought she heard FL100, and without telling anyone and neither I nor relief pilot noticing, she set FL100 in altitude window. Passing FL110, I stated to level off and she said that we were cleared to 100, which for the first time I noticed in the altitude window. I told her to climb back to FL110 as we were almost at FL105. Confirmed with cdg that we were cleared only to FL110. I am shocked that someone flying as -777 first officer would be so oblivious to standard air carrier X procedures as to put an altitude in the alert window without announcing it for confirmation. If you receive many of these types of reports, perhaps the procedure should be re-emphasized.

Title: B777-200 FO SET THE WRONG CLRED ALT INTO THE ALT WINDOW ON THE FLT GUIDANCE SYS.

Narrative: ALT. FO FLYING. CHKED IN WITH CDG APCH, LEAVING FL160 FOR FL110. REPLY: 'ACR X MAINTAIN FL110, DIRECT CRUEIL.' FO THOUGHT SHE HEARD FL100, AND WITHOUT TELLING ANYONE AND NEITHER I NOR RELIEF PLT NOTICING, SHE SET FL100 IN ALT WINDOW. PASSING FL110, I STATED TO LEVEL OFF AND SHE SAID THAT WE WERE CLRED TO 100, WHICH FOR THE FIRST TIME I NOTICED IN THE ALT WINDOW. I TOLD HER TO CLB BACK TO FL110 AS WE WERE ALMOST AT FL105. CONFIRMED WITH CDG THAT WE WERE CLRED ONLY TO FL110. I AM SHOCKED THAT SOMEONE FLYING AS -777 FO WOULD BE SO OBLIVIOUS TO STANDARD ACR X PROCS AS TO PUT AN ALT IN THE ALERT WINDOW WITHOUT ANNOUNCING IT FOR CONFIRMATION. IF YOU RECEIVE MANY OF THESE TYPES OF RPTS, PERHAPS THE PROC SHOULD BE RE-EMPHASIZED.
