| Summary: | Commercial flights are growing rapidly in various countries, including Indonesia,
because they are fast and can reach various regions, even areas that far away or isolated.
However, minor failures in the aviation often result in fatal accidents. Indonesia as an
archipelago in the tropics has great Cumulonimbus cloud forming potential. This research was
conducted to determine weather condition and characteristics of tropical lightning, also its
effects on commercial aircraft, as well as to know the steps of mitigating tropical lightning
strikes on commercial aircraft. By analyzing lightning strike data on commercial aircraft,
supplemented with various atmospheric data, this research succeeded in describing the
characteristics of tropical lightning such as the wide and high tower of Cumulonimbus clouds
that cause a lot of lightning strikes to commercial aircraft in tropical regions, as well as the
correlation of lightning strikes on commercial aircraft with the lightning strikes density at the
airport. Flights from / to Soekarno Hatta International Airport (CGK) are safest from lightning
strikes in July and August, while most dangerous in February and November. At the airport,
the most of lightning strikes occur at 13.00-19.00 WIB. In addition, descending is a flight phase
that is quite vulnerable to lightning strikes damage, thus it has been equipped with electric field
measuring device. To improve flight safety in the tropics, thunderstorm detection systems and
lightning strike density maps are needed to make lightning-free flight routes, also to increase
pilot awareness towards danger of lightning strikes on the flight route. Lightning Detection
System is the tools dan will be used by Air Traffic Controller to deliver the information to the
pilots to make the decisions for safety landing and take off. |
