To say that AF is just like any other private category flight is like saying Uber is just like getting a lift from a stranger. The fact that it is a charity does not absolve it from a responsibility to the "patients" for want of a better word. If there is no direct oversight then have mentor pilots to the low experience PPLs. who they can call on to help come to a reasoned decision to fly or not. The statement that the PIC can simply say no is as pointless as simply stating don't fly from VMC into IMC. It ignores all sorts of self-imposed pressures that a single pilot low time VFR pilot might place upon themselves. Rammel is asking the questions that the patients and there families would probably ask if they knew their pilot did not have much flying experience.
