Hi folks,
during my today's flight CPA17 VHHH-VOMM with Cathay Pacific's 747F B-LIC I experienced again with and only with EPR as primary thrust indicator an oscillating thrust while taking off and after some stabilsation again during my climb. (PMDG 747 V3 - FSX 3.00.8466)
1. The aircraft FMC was well prepared, the A/C not too heavy, TOW 255 tons only,
2. LNAV, VNAV armed, after 50% N1 I engaged TO/GA.
3. EICAS displayed a TO2 EPR of 1.43
4. The throttles rapidly move back and forth so that EPR oscillates between 1.56 and 1.33.
5. Similar during climb at FL270: EPR1.46 but oscillating between 1.58 and 1.32.
6. On top I witnessed that throttle levers were *not* in sync: In this occasion throttle lever of ENG1 moved forward (engine response accordingly) while the levers of ENG2-3-4 moved backwards. Their oscillation let the aircraft's nose wiggle, noticable on the ND as the dashed line of the path indicator waves like a dog tail. I checked by pushing E1234 that all levers *are* in sync, but to no avail.
Huh...
A. What is going on?
B. What is my mistake?
C. As somebody seen as well the out-of-sync thrust levers?
Thanx in advance.
