Narrative:

At approximately FL250 climbing to FL350, clearance was given to cross teede at FL350. Pms showed we should be at FL350 5 mi prior. As we continued the climb, the pms showed us getting behind on making the restr. At about 10 mi out and 2000 ft low, I took the aircraft off pms/autoplt and traded airspeed for altitude (.84 mach to approximately .80 mach). We were within 300 ft passing the fix. I should have realized it would be tight about 20 mi sooner. Then after leveling at FL350 the #4 engine flamed out. We declared an emergency and requested lower. As sf radio coordinated, I deviated from FL350 to keep the speed above .80 mach and the operating engines' egt's below the yellow range. We were about 700 ft low when we finally got a clearance for FL280.

Title: B747 ACFT IN CLB WAS 300 FT LOW MEETING XING RESTR AND SHORTLY AFTER LEVELING THE #4 ENG FLAMED OUT. EMER DECLARED.

Narrative: AT APPROX FL250 CLBING TO FL350, CLRNC WAS GIVEN TO CROSS TEEDE AT FL350. PMS SHOWED WE SHOULD BE AT FL350 5 MI PRIOR. AS WE CONTINUED THE CLB, THE PMS SHOWED US GETTING BEHIND ON MAKING THE RESTR. AT ABOUT 10 MI OUT AND 2000 FT LOW, I TOOK THE ACFT OFF PMS/AUTOPLT AND TRADED AIRSPD FOR ALT (.84 MACH TO APPROX .80 MACH). WE WERE WITHIN 300 FT PASSING THE FIX. I SHOULD HAVE REALIZED IT WOULD BE TIGHT ABOUT 20 MI SOONER. THEN AFTER LEVELING AT FL350 THE #4 ENG FLAMED OUT. WE DECLARED AN EMER AND REQUESTED LOWER. AS SF RADIO COORDINATED, I DEVIATED FROM FL350 TO KEEP THE SPD ABOVE .80 MACH AND THE OPERATING ENGINES' EGT'S BELOW THE YELLOW RANGE. WE WERE ABOUT 700 FT LOW WHEN WE FINALLY GOT A CLRNC FOR FL280.
