A short one to Gaseous:
Yes it is a positioning problem of the temp probe and a recertification-cost problem so it is cheaper to just placard the machine and put the resposibility on the pilot.
The Robinson-22 got developed on 2 main principles (after design and safety of course): price and weight. Find the cheapest way to do it and/or the lightest one too.
If you look carefully: in the R-44 you only have to apply carb-heat when in conditions conducive to icing and only to keep the needle out of the yellow.
You are in England? You better get used to scan the carb-temp-gauge permanently!!!!
I fly in Central America in a place with average temp of 25 deg centigrade day/night year around. If it rains or gets "cool" or foggy I watch it. No way to forget about.
I do agree:
I want:
-electronic fuel injection
-electronic timing and ignition
-electronic temperature controls
Magnetos got out of cars in 1928....

Unfortunately as it looks like pilots are the next thing getting eliminated from aircraft.........seeing all this automatic and/or remote controlled aircraft going online these days.........
