Abstract :
The need for takeoff distance needed by an aircraft, not only during the take off phase, but also needed for anticipation when the plane experiences a failure of
takeoff conditions both due to weather factors, technical factors and other factors, so
the takeoff distance is always corrected with the possibility the occurrence of rejected
takeoff. When the plane has not reached the speed of V1, the pilot can take rejected
takeoff but when the plane exceeds the speed of V1 the pilot is required to go around
or continue the takeoff phase. If the pilot forces to take rejected takeoff with a speed
exceeding V1, the aircraft is at risk of being out of control or exiting the runway.
The method of rejected takeoff calculation using takeoff performance
calculation. This calculation is based on aircraft ramp weight which includes the
aircraft's empty weight, passenger weight, baggage, cargo and the weight of the fuel
carried to carry out flight missions. By knowing ramp weight, takeoff performance
calculation can be done to be able to determine aircraft acceleration as a reference
for calculating speed V1 and aircraft deceleration which is a reference for
calculating the distance of the aircraft when doing rejected takeoff so that it can
determine the total takeoff distance on the flight mission.
From the analysis of takeoff performance calculations, it is known that
aircraft weight, air temperature and wind speed affect the total takeoff distance. With
a payload percentage of 90%, Airbus A320-200 aircraft require a total takeoff
distance of 1,637 meters while a Boeing 737-900ER requires 1,983 meters. Based on
the percentage level of cargo, the takeoff distance of the Boeing 737-900ER aircraft
is longer than the Airbus A320-200 aircraft.
