Buying a family plane (and performance calculations)

you see how far things can go

That seems to be the message that comes across, so we can set expectations right about targets for buying a family airplane.

Besides, 600m and up gives you access to plenty of places: there are not those many you are leaving out. Even then some may be unsuitable for your planned load and weather.

So yes, you can push the boundaries, but mostly we are looking at a reasonably priced aircraft which ticks most of these boxes:

• SEP/MEP (SET’s ruled out by price?)
• Seats min 2+2 or better 3+2 incl 2 each 1.8-1.9 m adults
• Can fly 300-600 nm
• Can use grass runways >600m (as opposed to “strips”? OP did not say anything on this, but it clearly opens up locations)
• Carries 30-50 kg worth of family luggage (OP useful payload was 350-400 kg, which is a lot)
• Price as close as possible to EUR150k (updated from the OP EUR 100k in parallel to the market price evolution)
• Easily hangarable (ie <11m wing span )
• >140KTAS desirable (on the idea that the family is limited by its flying time limitations, range of possible options increases with speed squared, ie twice as many options at 140KTAS vs 100KTAS)
• With family appeal of some kind
