Danish airline Cimber Sterling will use Lufthansa Systems’ navigation charts (Lido/RouteManual) and Lido/TakeOff for take-off performance analysis under terms of a five-year contract announced Monday. Lido/TakeOff calculates the optimal take-off data while taking all relevant factors – such as outside temperature, air pressure, runway length and conditions, and final aircraft take-off weight – into account. These calculations rely on the Lido Airport/Obstacle Data with respective Engine Out procedures (EOSID). Lufthansa says the systems will help the airline lower costs through optimizing the navigation and performance of its flights. The airline operates a fleet of three ATR 42s, four ATR 72s, 13 CRJ 200LRs, and five Boeing 737-700s.
