Abstract

A starter generator (DC generator) is a DC machine that acts as a motor when starting the engine and will become a DC generator when it reaches a certain speed. The DC Starter Generator will function as a starter mode when the speed is <45% NH and will become a DC generator mode when the speed is >61.5%. There are several types of starter generators on ATR aircraft: 8260-121, 8260-123, and 8260-124. The uses and functions of the three types are the same, but the maintenance schedule intervals are different. Therefore, the purpose of this study was to determine the planned maintenance intervals (brush change, bearing change, and overhaul) and the causes of differences in maintenance intervals for the starter generator. The type of research used is comparative research, where this research compares several parameters related to the planned maintenance of the Starter Generator, which will be operated within 10,000 FH. The results of the treatment intervals obtained are that types 8260-121 and 8260-123 each will require 16 times maintenance, while types 8260-124 only need 8 times maintenance. The difference in the number of treatments being less in the 8260-124 type is due to the modification of the brush. In addition, the type 8260-124 has also used a new technology commutator. Therefore, this type is superior to the other two because it can save operational aircraft costs.

Abstract

Unmanned aerial vehicles (UAVs) and advanced air mobility (AAM) offer potential alternatives for improving cargo and passenger transport in regions where conventional transport is constrained by distance, terrain, and fragmented geography. This study systematically reviews the use of UAV and AAM systems for connectivity in remote, rural, and inter-island settings. Following the PRISMA 2020 guidelines, searches were conducted in Scopus and Google Scholar through Publish or Perish. Of the 3,561 records identified, 74 peer-reviewed journal articles published between 2016 and 2026 met the eligibility criteria. The evidence was synthesised narratively and supported by descriptive frequency analysis and bibliometric mapping using VOSviewer. Unlike earlier reviews that primarily examine urban air mobility, last-mile delivery, or medical-drone applications, this review jointly evaluates cargo and passenger transport, supporting infrastructure, and operational challenges from the perspective of remote and archipelagic connectivity. Cargo and goods transport accounts for 92% of the included studies, whereas passenger transport represents only approximately 1%. Multirotor platforms are the most frequently identified aircraft type, while weather, regulatory and airspace constraints, and limited supporting infrastructure are the leading operational challenges. The findings show that passenger-oriented and inter-island applications remain substantially underexplored and require field-based validation, particularly in archipelagic regions.
