While I don't think Boeing will be concerned that the Nomad will threaten the position in sales records of DC3s and 737s .. for some niche operators, there is a view that the only aircraft able to replace a Nomad ... is another Nomad.
Gippy Aero is not going to have trouble selling small volumes to complement the other Types on their line. More strength if they can ramp it up to some decent sorts of numbers ...
