The flight activites and traffic of Malmi Airport were surveyed in December 2014 and January 2015 by a questionnaire that was sent to the companies and associations operating at the airport. The results are given below. 25 companies and associations answered the questions, and 17 of them have flight operations. The sums of their answers concerning flight activities were compared to the known totals of landings and operations. For both of these it was established that those who answered the questionnaire make up more than 95% of the total traffic of the airport. Private owners of airplanes and helicopters or owners of just one were not contacted.
Number of flights = number of takeoffs
Number of landings = number of touch-and-gos + number of full stop landings
Number of operations = number of flights + number of landings
(Helicopter flights are logged as one takeoff and one landing even if the helicopter touches the ground during its flight.)
