Narrative:

After having maintenance done, we had a delayed departure from basel, switzerland, to jeddah, saudi arabia. We were given a SID from basel clearance. On departure, there was significant WX en route. My copilot, very junior, was having a difficult time with the radios. The departure controller asked us our clearance. We had a different clearance than he was expecting and he assigned a heading. Within 2 mins, we were heading into a thunderstorm with severe turbulence. We requested a turn to the right. He also asked us our requested level. A series of radio calls ensued between my copilot and the controller on the altitude. We had been cleared to FL240, but I heard FL410 from the basil 3 times. At the same time, we were unable to maintain altitude because of a severe tossing about by the wind. I busted through FL240 and picked up a heading of 120 degrees trying to avoid a buildup. It was then I realized a TCASII picture of nearby traffic and the controller asking me my altitude. I immediately stopped climbing as best I could, still in turbulence. We had closed to within 2 1/2 mi and within 500 ft I believe. This is my first real time of being completely saturated with a combination of WX, inexperienced copilot, language problems, and the lot, and I found it illuminating. We cleared the traffic and proceeded to FL410 on that heading.

Title: ALT AND HDG DEV IN FOREIGN OP.

Narrative: AFTER HAVING MAINT DONE, WE HAD A DELAYED DEP FROM BASEL, SWITZERLAND, TO JEDDAH, SAUDI ARABIA. WE WERE GIVEN A SID FROM BASEL CLRNC. ON DEP, THERE WAS SIGNIFICANT WX ENRTE. MY COPLT, VERY JUNIOR, WAS HAVING A DIFFICULT TIME WITH THE RADIOS. THE DEP CTLR ASKED US OUR CLRNC. WE HAD A DIFFERENT CLRNC THAN HE WAS EXPECTING AND HE ASSIGNED A HDG. WITHIN 2 MINS, WE WERE HDG INTO A TSTM WITH SEVERE TURB. WE REQUESTED A TURN TO THE R. HE ALSO ASKED US OUR REQUESTED LEVEL. A SERIES OF RADIO CALLS ENSUED BTWN MY COPLT AND THE CTLR ON THE ALT. WE HAD BEEN CLRED TO FL240, BUT I HEARD FL410 FROM THE BASIL 3 TIMES. AT THE SAME TIME, WE WERE UNABLE TO MAINTAIN ALT BECAUSE OF A SEVERE TOSSING ABOUT BY THE WIND. I BUSTED THROUGH FL240 AND PICKED UP A HDG OF 120 DEGS TRYING TO AVOID A BUILDUP. IT WAS THEN I REALIZED A TCASII PICTURE OF NEARBY TFC AND THE CTLR ASKING ME MY ALT. I IMMEDIATELY STOPPED CLBING AS BEST I COULD, STILL IN TURB. WE HAD CLOSED TO WITHIN 2 1/2 MI AND WITHIN 500 FT I BELIEVE. THIS IS MY FIRST REAL TIME OF BEING COMPLETELY SATURATED WITH A COMBINATION OF WX, INEXPERIENCED COPLT, LANGUAGE PROBS, AND THE LOT, AND I FOUND IT ILLUMINATING. WE CLRED THE TFC AND PROCEEDED TO FL410 ON THAT HDG.
