The Enroute Terrain Analysis provides pilots with the required flight route in an emergency
Enroute Terrain Analysis (ETA) is an expansion to Lido OC which ensures pilots have access to the flight route they need in an emergency. If an engine fails during flight or if there is a loss of pressure in the aircraft, the pilot will have to take the plane to an altitude with sufficient oxygen within a certain amount of time. In principle, neither emergency situation is critical if there is sufficient clearance between the terrain being flown over and the so-called level-off altitude, the altitude which can be maintained with one remaining engine. A critical situation may arise when flying over high mountains, however. With the help of Lido OC, the optimal flight path can be calculated while taking terrain clearance into account.
Worst-case scenario must be covered
Many airlines still use back-office processes for traditional terrain analysis. However, these are very complex and ultimately costly as well. Another major disadvantage is that, in order to cover the worst-case scenario, very conservative assumptions must be made regarding the conditions affecting a driftdown situation (weather, aircraft weight). In this case, the route that has been researched must be used as the pre-defined route. With this type of solution, it is not possible to calculate the minimum cost or fuel track, which can differ from day to day.
By researching the route during the dispatch process, or automatically during flight path optimization, the operations parameters and environmental conditions relevant to the respective flight can be used. So the pilot receives immediate access to current decision-making and collision avoidance advice for each flight event.
