The story behind the white noses.
Phil Johns our Avionics LAE held a strong view that a white nose would keep the avionics and perhaps, more importantly, the NiCad battery cooler.
He placed thermo sensitive strips under the black nose and took measurements in the summer. We then painted one nose white and took readings. The ravages of 'gin and time' deny me the ability to remember the difference, however we did paint the others white after analysing the results.
We, in fact, didn't carry too much in the way of avionics in the nose as they were unstabilised ships (straight rods) and panel mounted KX175 VHF Nav Comms. Nevertheless, we did think at the time they looked "cool" UG
