Abstract [sv]

Tjänstgöringstid och dygnsvila är för ambulanshelikopterpiloter strikt reglerat. Avgångar och ankomster styrs av inkommande larm, vilket kan göra beräkning av tjänstgöringstid och dygnsvila komplicerat. I dagsläget görs beräkning och loggning manuellt, vilket kan generera osäkerhet med onödig larmfrånsägning som resultat.

I detta arbete utförs en förstudie till ett tidsloggningssystem för ambulanshelikopterpiloter, med huvudsyfte att minska onödig larmfrånsägning. Ett IT-system skapas där en smarttelefon samlar in tidsdata som sedan presenteras i en webbapplikation.

Som del i systemet utforskas möjligheten att automatiskt kunna logga flygtid med smarttelefon. En mobilapplikation ämnad för automatisk flygtidsloggning skapas med underlag och idéer hämtade från tidigare forskning och datainsamling. Resultatet visar att applikationen under testning loggar samma flygtid som helikoptern i 5 av 6 fall, med en minuts noggrannhet.

För presentation av insamlade tidsdata tas en visualiseringsmodell fram i form av en webbapplikation baserad på tidigare forskning och vedertagna designprinciper. Testning av visualiseringsmodellen visar att det, för piloterna, är lättare att fatta rätt beslut under tidspress med framtagen visualiseringsmodell än med numeriskt format av samma data. Resultatet analyseras med bland annat t-test som visar att skillnaden mellan graf- och tabellpresentation är statistiskt signifikant.

Abstract [en]

Active duty time is strictly regulated for ambulance helicopter pilots. Departures and arrivals are determined by incoming alarms, which can make active duty time calculations complicated. These calculations are currently done manually, which can generate uncertainty and unnecessary denial of incoming alarms as a result.

In this work, a pilot study is made for a time management system for ambulance helicopter pilots, with the main purpose to decrease unnecessary denial of incoming alarms. An IT-system is created where a smartphone collects time data which in turn is presented in a web application.

As a part of the system, the ability to automatically log flight time with a smartphone is explored. A smartphone application with the purpose of automatically logging flight time is made with its basis and ideas retrieved from previous research and data collection. The test result shows that the application logs the same flight time as the helicopter in 5 times out of 6, with the accuracy of one minute.

For presenting the collected time data, a visualization model is made in the form of a web application based on previous research and established design principles. Testing of the visualization model shows, for the pilots, that it is easier to make an accurate decision under time pressure with the developed visualization model than with a numerical format of the same data. The result is analyzed with a t-test which concludes that the difference between the graphical and table presentation is statistically significant.
