Platform Overview

The Cessna 303 Crusader was introduced in the early 1980s as part of Cessna’s effort to modernize its light twin-engine lineup. Designed from the ground up rather than adapted from an older airframe, the 303 featured an all-metal, low-wing design, improved aerodynamics, and a fully enclosed cabin that offered exceptional visibility and comfort for its class. It was also Cessna’s first light twin to use counter-rotating engines, enhancing stability and safety by eliminating critical engine tendencies.

Built with both performance and practicality in mind, the Crusader delivers an ideal balance of speed, range, and fuel efficiency. Its low-noise propellers and well-insulated cabin create a noticeably quieter environment, reducing fatigue for pilots and crew—an important advantage on long survey missions. The spacious interior and large cargo door design make it highly adaptable for sensor installations and special mission configurations, while its solid handling and dependable systems make it a favorite among pilots.

At Helios, the Cessna 303 represents a reliable, capable, and refined platform—combining the proven engineering of Cessna’s legacy with the modern upgrades needed to meet today’s demanding aerial survey and data collection missions.

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.

High-Wing Fleet

Helios manages a nationwide network of trusted high-wing aircraft, such as Cessna 172s, 182s, and 206s, ideal for low to mid altitude imaging and mapping missions. These aircraft are valued for their stability, efficiency, and excellent downward visibility, making them a cornerstone of aerial survey operations.

Each platform in our network is carefully vetted for airworthiness, performance, and compliance with FAA commercial standards. Their high-wing configuration provides unobstructed sensor views and safe, reliable handling in a wide range of conditions. Combined with Helios’ operational oversight and mission planning expertise, this network allows us to deploy capable aircraft quickly and cost-effectively anywhere in the country.
