Piper Chieftain PA31-350
Platform Overview
The Piper Navajo Chieftain PA-31-350 is a proven workhorse in the world of twin-engine aircraft, known for its power, reliability, and generous cabin space. Introduced in the late 1970s as the largest and most capable variant of Piper’s Navajo line, the Chieftain was designed to meet the needs of operators who required greater payload, range, and versatility. Equipped with counter-rotating turbocharged Lycoming engines, the PA-31-350 delivers strong climb performance and dependable operation under a variety of conditions.
The Chieftain’s large, six passenger cabin comfortably accommodates crew, equipment, and mission systems, making it ideal for extended operations and multi-sensor payloads. Its wide center of gravity range and high useful load allow for flexible interior configurations and sensor installations without compromising performance. Modern avionics upgrades, smooth handling, and robust systems further enhance safety and efficiency during complex missions.
For Helios, the Piper Navajo Chieftain serves as a versatile and capable platform—balancing range, endurance, and payload capacity with the comfort and reliability required for demanding large aerial imaging and LiDAR collection projects.
