Inadvertent in-flight inflation of an inflatable slide associated with a non-co-located over-wing emergency door of an aircraft fuselage is prevented by a system having a source of compressed gas (e.g., a compress air cylinder) and a 3-way valve having an input port and a pair of output ports each being individually connectable to the input port. The 3-way valve is operable in response to a control signal so as to fluid-connect the source of compressed gas with either a vent line which vents the compress gas overboard or a supply line the inflatable slide. When the control signal fluid connects the gas source to the vent line, the system will be in a safe in-flight mode indicative of inflight operation of the aircraft in which case inadvertent inflation of the slide is prevented.
