Pilot’s Operating Handbook Section 7
EXTRA 500 Description of Airplane and Systems
However, a significant higher fuel consumption due to landing
gear drag and reduced cruise speed has to be considered.
Note Refer to Section 3, Landing Gear Emergencies.
A warning horn combined with the red GEAR WARN light on
the annunciator panel is furnished to caution the pilot against a
landing with landing gear retracted:
Firstly, the warning light and horn will be activated in case of
the throttle is set below the power setting normally used for
landing approach, flaps 0° or 15° and the landing gear is not
fully extended and locked. If landing is not intended pressing
the
GEAR WARN MUTE button located at the left side of the
power lever will switch off the horn and the warning light.
Opening the throttle again will reset this warning system.
Secondly, when the power lever is set below the power setting
normally used for landing approach and wing flaps are in
landing position (30°) the warning light will illuminate and the
warning horn will sound independently from the
GEAR WARN MUTE button until landing gear has been
completely extended and locked.
In flight the extension of the landing gear will cause a slight
nose down moment and a decrease of airspeed. The stall speeds
are not affected by landing gear operation.
