I believe pilots should have technical knowledge as long as it does not interfere with their duties as pilots. This knowledge should be geared to help them describe their discrepancies, really some 34 and 22 basic training would really help, mabe 23 as well. Very simple troubleshooting info to give us the data to help better define a problem. It is not really very technical just to help a pilot create a PDIS that is more defined. It would reduce the erronous number of PDIS that we often CND. Help them understand what the aircraft they are flying is actually capable of doing.
