Abstract :
Many Boeing 737-800NG and Boeing 737-900ER aircraft are operated by
airlines in Indonesia, one of which is Lion Air and Garuda Indonesia. When operated
at an airport that has runway length spesifications, runway obstacle, runway slope,
runway elevation, and aircraft runway strength will experience a decrease in takeoff
performance, Maximum Takeoff Weight, load capacity and under load.
To determine the Maximum Takeoff Weight using the line drawing method in the
graphs of the Flight Planning and Performance Manual (FPPM Boeing 737-800NG
and Boeing 737-900ER) using the results of research data in the form of primary data
and secondary data, such as runway characteristics, wind speed and direction, and
movement data of passengers using Boeing 737-800NG and Boeing 737-900ER type
aircraft Garuda Indonesia and Lion Air.
From the results of the study, it was found that several aircraft operating had a
decrease in Takeoff Weight by Structure and by Performance. The cause of the decline
in this study was due to differences in air temperature conditions, wet runways, and
wind conditions in wind tail.
