For those in the know:
How many "possitions" does the Ground Control Relay has?
If you "find it in the off possition", could it just have tripped itself? (I.e. is it suppossed to trip under shortcuts or other electrical malfunctions?) Or is it totally neccessary that someone physically puts it in that possition (knowingly or inadvertenly)?
Also, is it in the pilot's mandatory checklist to check that all the circuit breakers (except those turned off for delayed maintenance) are on?
And last: Do manufacturers keep a knowledge base that could be downloaded to a laptop where a technician could type: "probe heater turned on while on ground" and get an answer such as: "check WOW sensor opened or closed", "check gnd relay CB set or out"? Shouldn't it exist?
Two more survivors have been discharged from the hospitals. Only one remains in intensive care in very serious condition.
