A Cessna Citation Encore flying at night around a line of thunder storms west of St Louis. During the cockpit view you can see the instrument panel labels are illuminated with electro luminescent lights that illuminate the lettering on the panel. The instruments are either illuminated internally or by post lights and the tubes for the pilot flight displays and the multifunction display are internally lighted monitors. As we enter the terminal area for our landing at Cahokia airport we get a great view of the lights of St. Louis. The Citation Encore is an upgraded Citation V with a hot wing, Primus 1000 avionics and Pratt and Whitney PW535A engines
