And most real farm strips are not advertised on Skydemon unless you are member of the Flying Farmers Association then they can be added to Skydemon but not always the case.
^ correct.
There are airfields, then there are grass airfields, then there are airstrips, then there are farm strips, and at the far end of the scale there are fields you can land in.
I have the FFA overlay on my SkyDemon and I’d agree with you that the vast majority of them are very much farm strips, used relatively infrequently, and you are quite literally landing on someone’s property, with very little prior information available.
The far end of the scale are fields that probably haven’t ever been landed in, but mean you can get as close to your destination as possible. Much of the time you can make a prior visit by car. On the odd occasion this isn’t possible, a low pass or two is critical, not just to see the surface, and to check you’re not about to fly into running livestock, but also to work out what the wind is doing at ground level once it’s passed over nearby obstructions.
I also agree with people above that the aircraft dictates what’s a challenge or not, combined also with pilot competence. A numpty in a Carbon Cub won’t be safe at a 500 metre strip, whereas a skilled/regular Jodel flyer with good speed and height discipline can regularly operate from 350 metres.
Never criticise a man until you’ve flown a mile in his loafers.
