JetStream FS is an independent flight simulation development studio dedicated to producing top-tier, twin-engine General Aviation aircraft natively built for X-Plane 12. Founded around the "Capt. Iceman Series" (CIS), their design philosophy centers on systems depth, tactile hand-flying characteristics, and immersive cockpit environments.
Their fleet focuses on classic Piper multi-engine workhorses: the CIS PA-44 Seminole (a staple multi-engine trainer), the turbocharged CIS PA-34 Seneca II, and the commuter-sized CIS PA-31-350 Chieftain. Rather than offering basic default systems, JetStream FS models progressive oil consumption, cold-weather engine start behaviors, component wear persistence, and realistic turbocharger wastegate logic.
To bridge the gap between desktop simulator gear and real controls, their aircraft incorporate custom input-response profiles designed to simulate the heavier, deliberate feel of multi-engine flight controls. With support for third-party avionics (such as RealSimGear and TDS GTNXi), custom FMOD sound packages recorded from real aircraft, and continuous flight model tuning for modern X-Plane flight dynamics, JetStream FS has rapidly become a premier studio for multi-engine GA flying.
