Yes, I know those jacks, made one myself. I've seen them demonstrated by lifting an already inflated tyre, easy. I've yet to see one that can easily lift from a completely flat situation. The much larger angles and extra amount of lift needed don't work so easily. Ask to see one tested from dead flat, on a dirt surface.....
A spare tube or patch kits are useless without an adequate jack to get the wheel off. Not always easy to find a good jacking point on aircraft landing gear. Been there and caught out that way.... I've found that the pressurized magic bottles are the best way to go. Got me out of trouble once and helped a couple of others.
It seems that the office is now sending reminders that BFR or Medical are due in one month. That's really useful because it's so easy to lose track of time and BFR expired before realize it......
Would it make sense to widen the criteria to include on-field (or nearby) accommodation that you need to pay for.
This map Airfields near Fuel, Pub and Food' pretty much does that already, l in that any pub will have accommodation or nearby. There is plenty of such accommodation available, which I do use sometimes when necessary.
I'm seeking that free or near free really basic accommodation. Ideal would be an old caravan parked on the airfield. Just a dry bunk for overnight is all I seek.
I realize all the restrictions on such, so I really applaud those airfields that find a way to do it anyhow.
