Narrative:

Upon departure of runway 23 at lsgg; climbing on the konil 2 juliett SID; ATC informed flight crew of terrain in vicinity of position; questioned if terrain was in sight; and issued a climb to 7000 ft. Initial flight conditions were intermittent IMC at time of ATC question of whether terrain was in sight; with a negative response from the flight crew. Immediately following the negative response; terrain became visible. Flight crew did not inform ATC of visual contact with visible terrain. At no time did GPWS indicate conflicting terrain or threat. ATC issued a command to climb to 7000 ft to avoid terrain which was performed at a maximum rate of climb. ATC advised the flight crew that the maximum speed for the konil 2 juliett SID was 190 KIAS; with a bank of 25 degrees. The aircraft FMS was programmed to follow the konil 2 juliett SID; which included the 190 KIAS speed restr and bank angle. The aircraft was being manually flown with guidance from the flight director and FMS LNAV source. Autothrottles were utilized and operating properly. Contributing factors: 1) encountering a tailwind during the initial climb and turn pushed the aircraft outside of the protected region of the SID. 2) moderate to severe turbulence during the initial climb and turn limited climb rate and bank angle. Future flight crew actions: 1) strict adherence to SID departure instructions with increased awareness of contributing factors such as a tailwind component which would modify the normal flight path. Supplemental information from acn 698515: closer attention should have been monitored to actual flight path of the aircraft with respect to strong wind conditions.

Title: A GV DEPARTING LSGG RECEIVED A TERRAIN ALERT FROM THE DEP CTLR. CREW CLBED THE ACFT TO SAFE ALT.

Narrative: UPON DEP OF RWY 23 AT LSGG; CLBING ON THE KONIL 2 JULIETT SID; ATC INFORMED FLT CREW OF TERRAIN IN VICINITY OF POS; QUESTIONED IF TERRAIN WAS IN SIGHT; AND ISSUED A CLB TO 7000 FT. INITIAL FLT CONDITIONS WERE INTERMITTENT IMC AT TIME OF ATC QUESTION OF WHETHER TERRAIN WAS IN SIGHT; WITH A NEGATIVE RESPONSE FROM THE FLT CREW. IMMEDIATELY FOLLOWING THE NEGATIVE RESPONSE; TERRAIN BECAME VISIBLE. FLT CREW DID NOT INFORM ATC OF VISUAL CONTACT WITH VISIBLE TERRAIN. AT NO TIME DID GPWS INDICATE CONFLICTING TERRAIN OR THREAT. ATC ISSUED A COMMAND TO CLB TO 7000 FT TO AVOID TERRAIN WHICH WAS PERFORMED AT A MAX RATE OF CLB. ATC ADVISED THE FLT CREW THAT THE MAX SPD FOR THE KONIL 2 JULIETT SID WAS 190 KIAS; WITH A BANK OF 25 DEGS. THE ACFT FMS WAS PROGRAMMED TO FOLLOW THE KONIL 2 JULIETT SID; WHICH INCLUDED THE 190 KIAS SPD RESTR AND BANK ANGLE. THE ACFT WAS BEING MANUALLY FLOWN WITH GUIDANCE FROM THE FLT DIRECTOR AND FMS LNAV SOURCE. AUTOTHROTTLES WERE UTILIZED AND OPERATING PROPERLY. CONTRIBUTING FACTORS: 1) ENCOUNTERING A TAILWIND DURING THE INITIAL CLB AND TURN PUSHED THE ACFT OUTSIDE OF THE PROTECTED REGION OF THE SID. 2) MODERATE TO SEVERE TURB DURING THE INITIAL CLB AND TURN LIMITED CLB RATE AND BANK ANGLE. FUTURE FLT CREW ACTIONS: 1) STRICT ADHERENCE TO SID DEP INSTRUCTIONS WITH INCREASED AWARENESS OF CONTRIBUTING FACTORS SUCH AS A TAILWIND COMPONENT WHICH WOULD MODIFY THE NORMAL FLT PATH. SUPPLEMENTAL INFO FROM ACN 698515: CLOSER ATTN SHOULD HAVE BEEN MONITORED TO ACTUAL FLT PATH OF THE ACFT WITH RESPECT TO STRONG WIND CONDITIONS.
