During a demo with Porter Airlines Inc., we measured core temperatures right next to the adapter — a more accurate indicator of engine readiness than EGT readings, which often misrepresent cooling since much heat escapes to the rear of the engine.

Results Overview

Natural Cooling

  • Temperature drops only ~2°C every 5 minutes.
  • After ~40 minutes, cooling stalls, leaving the engine hot for 5+ hours.

FCS Cooling (AFC-22 Jet Engine Cooling System)

  • Near the BSI plug, temperature reaches 30–40°C after ~40 minutes → BSI readiness in 25–30 minutes.
  • Brings the entire engine down to safe operating temperatures up to 10× faster.

Key Takeaway:
Relying on EGT alone can be misleading, and natural cooling wastes valuable time. With FCS jet engine cooling, operators gain faster inspections, safer operations, and dramatically shorter turnaround times.

Operational Impact:
Shorter ground times mean airlines can fly more with the same fleet, increasing available flights without adding aircraft. Faster engine readiness translates directly into higher utilization and improved operational efficiency.
