I like how easy it is to work with Flightline compared other software we have used in previous jobs (ie Avasoft). Also that they are constantly improving their product - which makes me feel secure about our future use of this program! Nothing so far!! Just continue using them as my employer has been very pleased thusfar. We love having an aircraft management system at hand whenever needed from any location via web browser or mobile application platform-it's great not needing multiple apps/programs running simultaneously nor being tied down by desktop applications when out flying airplanes.-ability quickly access historical information such data logs & engine run times etc..
