B747-400 Quick Fixes
Being new to the B747-400 I wondered if anyone had a list of quick fixes. Nothing special, just what is in the FIM would do. But for those last minute problems I need a list of resets that might work.

Yes I work a lot on narrow body airbus and complete power down is a last result that sometimes works. But for the airbus, we have an excellent circuit breaker trip list for common defects which came from Monarch. I was trying to get a similar list for the B747. I shall have to sit down with the FIM and copy them out. In the good old days with a paper FIM you could quickly look it up (we carried the FIM in our van), but now its on CD it takes too long. I carry a laptop in the van with the FIM loaded in the hard-drive, but it takes time to page through a computor. Anyway come 01 Nov we go back to B777 for the winter, and the FIM is miles better so should be OK.
Anyway if anyone has a list of CB trips for B744 then I would be most grateful

Equipment cooling
Status messages concerning E/E cooling can often be cured by rotating the equipment cooling switch on the P5 panel to override and then back to NORM.
The E/E cooling air exhaust valve quite often sticks in closed pos. on ground, despite a modification program.
More:
There are four AC and four DC CBīs on the overhead panel for the flt control PSMīs (power supplies).
Pull all of them and push in the DCīs first, then the ACīs.
Great fix for status messages generated after overnight parking or after unwanted power interruption.
Take care,
Ballpoint. (15 years of -400 and still like them)

I have just what you need, a few pages of tips and tricks for the 744, sorted by ATA, in a Word document, sized to be cut, laminated and kept in your pocket for quick fixes.
Anyone interested drop me a line under [email protected] and I will send you a copy via email.
