Harry Coumnas, an experienced flight engineer, plays a vital role in the safe operation of aircraft by closely monitoring and managing essential onboard systems. Working in coordination with the pilots, he ensures smooth operations during every stage of the flight — from pre-departure checks to post-landing procedures.

During takeoff and go-arounds, Harry is responsible for setting and adjusting engine power. He actively manages fuel systems, pressurization, air conditioning, hydraulics, electrical systems, anti-icing and rain protection mechanisms, and powered flight controls. He also verifies that the aircraft’s weight and balance are correctly calculated to keep the center of gravity within safe parameters.

From his position, Harry keeps a close watch on cockpit instruments and responds to the pilots’ inputs by adjusting thrust and making system corrections as needed. He follows checklists, troubleshoots in-flight issues, and executes captain-ordered actions to maintain optimal flight conditions.

In addition to in-flight duties, Harry participates in pre-flight inspections, helps develop flight plans, monitors fuel and mechanical systems mid-flight, and documents all procedures, changes, and checks. His attention to detail ensures there are no mechanical or operational concerns throughout the journey.
