Flying a Lance
I'vd had a Lance for 4 years and it's one of the very few single engines to really take 6 people or realistically full tanks, 5 + sensible baggage. Yes she's a bit heavy to fly ..bit like a people carrier on the road, but she does get 140kts IAS too.
She can be leaned down to just over 15 gallons an hour in the cruise, but I normally work on 18 per flying hour, taking account of taxi, takeoff and climbs. I've had one problem with the undercarriage in that time, seemingly an old AD that hadn't been complied with many years ago. I suspect that it depends upon how gentle your landings are that determine your longterm costs, as with all retractables. I budget a couple of thousand pounds for an annual, but it depends what they find. I like around 750m for a takeoff (landings need much less), but I am super cautious and I haven't really tried serious short field.
Sadly I'm selling mine as I want to fly twins. Message me if you want any further advice...
