One of the key factors affecting flight safety nowadays is human error in take-off performance data insertion and take-off execution in contradiction to carried out calculations. StorkJet has developed EFB application that supports pilots with prompt advisories if any errors or miscalculations are observed.

The consequence of take-off performance related errors

  • Tail strike
  • Runway excursion
  • Rejected take-off
  • Reduced take-off performance
  • Degraded aircraft handling qualities
  • TO/GA engine thrust used instead of flex/de-rate
  • Increased runway length required
  • Overweight take-off
  • Reduced obstacle clearance
  • “Despite advanced aircraft systems and robust operating procedures, accidents continue to occur during the take-off phase of flight. The take-off is recognized as one of the most, if not the most, critical stage of flight, as there is limited time and options available to the flight crew for managing abnormal situation such as insufficient airspeed. This has been highlighted by the accident statistics that show between the period 2000 and 2009, 12 per cent of fatal accidents involving the worldwide commercial jet fleet occurred during the take-off, despite the fact that this phase of flight accounts for about only one per cent of the total flight time.”

On the basis of past events and published safety reports all worldwide Aviation Safety Agencies agreed that airlines and aircraft manufacturers should pay particular attention to minimize the risk of take-off performance related errors and to develop an effective way of their prevention. In response to the recommendations issued by the Safety Agencies and the fact that the role of decision support systems and in-flight monitoring applications will constantly gain in importance StorkJet has prepared the tool to improve safety and to eliminate the risk of human error in take-off performance calculation process. Safe Take-off Performance „STOP” application aims to support the work of the pilots by verifying the correctness of the data input and it also monitors assumptions such as runway selection, aircraft configuration or atmospheric conditions during actual flight operation. Flight crew is provided with alerts and advisories if given data or assumptions used are not correct.
