Viscount 700 & 800
I flew both types & as Centaurus said the 700 series cockpit layout left a lot to be desired, in fact it was bloody awful to the point of being hazardous. It seems there was no pilot input sought & engineers put instruments & switches where they found space.
The 800 series was a different aircraft altogether - the first 800 Series acft were purchased by Capitol Airlines in the USA & the story is that the Chief pilot of Capitol told Vickers how he wanted
the cockpit laid out . The result was a very pleasant acft to operate. I didn't much favour everything ( gear & flaps ) hanging on the one mainspar though. Nevertheless a delight to fly.
