Strobe lights are controlled by a switch on the overhead console.
STEP LIGHTS (OPTIONAL)
Step lights are installed together with the electrically-retractable step (see
chapter 25-00) and provide illumination of the external stepping area for
passengers.
The step light is controlled by the UTILITY switch on the overhead console.
ROTOR LIGHTS (OPTIONAL)
The rotor lights comprise two main rotor lights, two tail rotor lights and the
ROTOR LTS switch on the Auxiliary panel in the overhead console.
The rotor lights installation is intended to illuminate two portions of the main
rotor (right side and left side) and the tail rotor. These lights allow the crew to
identify, during night time ground and hover condition, the extremity of the
main and tail rotor discs.
The ROTOR LTS switch is a three position switch labelled OFF / MAIN /
BOTH.
When set to MAIN the main rotor lights are illuminated; when set to BOTH
the main and the tail rotors lights are illuminated; when set to OFF the rotor
lights are switched off.
The rotor lights are not NVG compatible. If NVG installation is present, then
in the NVG COVERT mode the main and tail rotor lights are automatically
selected to OFF.
