2. define \flight time\.

Explanation:

Question 29: Define "Airworthy"

"Airworthy" refers to an aircraft (or its components) meeting regulatory, design, and maintenance standards to safely operate in intended flight conditions, per aviation regulations (e.g., FAR). It ensures structural, mechanical, and operational fitness for flight.

In aviation, "flight time" is the period from an aircraft's engine start (or brake release for helicopters) until engine shutdown (or landing for helicopters), used for pilot logging, operational, and regulatory purposes (varies by authority, e.g., FAR 1.1 defines it for pilots as time from takeoff power to landing power application).

Answer:

An aircraft (or its parts) is airworthy when it conforms to approved design, is in safe operating condition via maintenance, and meets aviation regulatory requirements (like FAR) for safe flight.
