CKHY,
We all started in Cessna's. So, I am not belittleing you in any way. Your question is a very broad one. If you want to know what you have lost or not lost, you really need to go through a full systems course on the 747. The systems are so redundant, that you can deal with just about everything in another way. Some of the abnormal procedures are a bit long winded, but they are the approved procedures. When you stack multiple emergencies upon one another in a critical phase of flight, crews need to determine which to do in which order. That can be a crap shoot.
Get ahold of an old sytems book somewhere, study it! Boeing has come up with procedures to deal with just about everything. Posting a systems book or procedures manuel on here is not practical.
Evaluating what happened in the El Al Accident was done by the professional accident investigators.
If you understand the 747 systems, then you can make sense of the report, but untill then, don't even try. You will have more questions than answers.
Hope I didn't discourage you.
Good luck with your project!
