Centaurus I always enjoy reading your posts on here. Back when I begun my training ( 5 years ago) the mnemonic BUMFISH was widely used to teach us the before landing checklist in the Cessna 172. Compared to the POH which has only 4 items, I find it unnecessary for the other checks to be implemented. It consumes the students time and distracts them whilst flying on the downwind leg. Their mind should be more focused on handling the aircraft, maintaining straight and level, looking out for aircraft and having good airmanship!
As for the costs of flying. It's a very expensive investment, but nonetheless absolutely worth every penny in my book. Your grand daughter always has the option of going to a VET FEE-HELP funded course. I worked and saved for most of my training. I'm sure they're a few flying schools who offer reasonable priced training. Just need to shop around and find a bargain
