Appeal No. 97-1229
Application 08/280,950
The invention is directed to a fire warning system in
an aircraft. More specifically the engine cowling of the
aircraft is equipped with a light transmission means which has an
inner end in communication with the interior of the engine
compartment and an outer end visible to the pilot of the
aircraft. The light transmission means transmits any light from
flames in the engine compartment to a position visible to the
pilot.
Claim 9 reproduced below is further illustrative of
the claimed subject matter.
1. In combination:
an airplane having an engine cowling;
said cowling having a top portion which is visible to
the pilot of the airplane;
a light transmission means having an inner end in
communication with the interior of said cowling and an outer end
positioned on said top portion of said cowling which is visible
to the pilot of the airplane so that if a fire should occur
within the engine cowling, the light from the fire within the
cowling will be visible to the pilot.
