We have a medical situation,Is there a Doctor or Nurse on the plane?

Ever been flying and hear the flight attendant announce overhead "Is there a Doctor or Nurse on the plane?"  Have you ever wondered what liability you have when you provide emergency medical assistance in this situation? Under the Aviation Medical Assistance Act, anyone (including physicians) that provides medical assistance on an airplane is protected from liability, as long as they did not act with willful or wanton misconduct (gross negligence).   Aviation Medical Assistance Act 1998 (H R 2843).
