Note that there are developments in smaller aircraft. For insance, the
venerable Twin Otter (Dash-6) was relaunched by a Victoria Canada firm
(Viking air) who got the designs/rights from Bombardier and new new ones
in about 2 years. *This is a 19 passenger aircraft. It is used a lot in
the caribean for inter island hops for instance (it can be fitted with
floats, skis etc). However, this aircraft won't have huge performance
gains over the original twin otter.

BTW N24 Nomad and Dornier 228 are re-entering production just as the
Twin Otter.

Gippsland, who bought the Nomad's type certificate from Boeing
Australia, plans to fit uprated Rolls-Royce turboprops with new
propellers. It may have a glass cockpit too.
