Hello Expertise

Inboard engine are furnished with ice detectors system, why these are not installed in outboard engine. any technical reason

At one point in time all engines had ice detectors, made it nice because we always had a spare. Sometime in the mid 80's the manufacture ran into a problem with faulty detectors so our good spare detectors were removed from 1 and 4 to take care of the demand, unfortunately they never replaced them.

Thanks, my question is # 2 & 3 ice detections sys are working parallel Test simulation also 1 & 2 if we remove the inboard engine detectors & installed outboard engine it make no difference

The outer engine ice detectors were removed by TCTO 1C-130-1125, dated Nov 1, 1983. This TCTO also removed all of the detectors from spare engines. I do not have a copy of the TCTO stating the purpose, but they are not needed.

A long time ago an FE told me, they only worked in the 2 and 3 position but all engines were the same so they could be interchangeable.

thanks for useful contribution, still i could not clear my query, ICE detection system, no aircraft wiring for #1 & 4 if we removed inboard engines ice detectors & installed on outboard engines, is system will work? No so why ice detections are provided from in inboard engines. is it due aerodynamic reaction.

I don't know Munir, I am not an engineer. It could be due to aerodynamic reaction from the nose of the aircraft that would make the inboard engines ice up faster, so there is no need for outboard detectors. Maybe they decided that there is no difference, and it would not be worth running the wiring for two more engines.

And yes, if you ran the #3 wiring to engine #4 and installed the detector, it would probably work. But, if the inboard engines do ice up faster, then it may cause serious problems. Also, you would have to find room in the wing disconnect connectors for the wiring.

Can't remember the who what or where but recall it has to do with the horizontal stabilizer being directly aft of the inboard engines... May be BS but that's all I can remember...
