| All advisories and airworthiness directives warn of the dangers of extreme heat surrounding the batteries-especially during ground operations. References are made to the "ambient temperature". Inadequate ventilation of battery compartments is given as a possible cause of thermal runaway. | All advisories and airworthiness directives warn of the dangers of extreme heat surrounding the batteries-especially during ground operations.
