Does the Westland Sea King have emergency start ?
Not as such but you can start it in manual control using the manual throttle and then re-engage computer control once at ground idle.
Fake Sealion - if the HAS 2 has the same Gnome engine and fuel computer as the Mk3 and 3A, the Light Up Sensor delete switch was used for very low OAT starts. The fuel computer looks for specific Ng and PTIT levels before it allows the throttle to open and accelerate from min flow to flight idle - the LUS delete deselects that function.
