In recent times, legal issues have appeared regarding the use of NEVHGC sites by pilots who wish to take their friends/acquaintances for a non-commercial tandem flight. This is because the passenger may well be a neither member of HGFA nor of NEVHGC. Taking such persons for flights off NEVHGC sites exposes you, as the “pilot in command”, to legal action from that person should that person injure themselves, or suffer some other damage or loss.
You are totally responsible for the health and welfare of your passenger. NEVHGC is in no way responsible for your tandem flying.
However, to assist tandem pilots in this situation, NEVHGC has devised procedures that facilitate all passengers in tandem flights conducted off NEVHGC sites being either a member of HGFA, or a member of NEVHGC. The Constitutions of both these organisations hinder legal action against fellow NEVHGC or HGFA members and increase your level of protection.
