good question
The Navajo is an excellent aircraft for short range, below 10,000ft trips, and I have been there and done that.
Unless the destinations have good prepared runways, and are over 500nm away, then whilst a Citation is a great little private owners aircraft, is not ideal.
A B90, or 200 is an ideal replacement, with high profile tyres, good at rough runways, and grass, likes longer trips, 1000miles easy work, and a great aircraft to fly.
If U want more details, please Pm me.....Bumz
