What factors affect the performance of a test flight?

What factors affect the performance of a test flight?

Several factors can influence test flight performance, including weather conditions, aircraft weight, and engine efficiency.

How does weather impact the test flight performance?

Weather can affect lift, drag, and engine performance. For example, strong winds can alter flight paths and increase fuel consumption.

What role does aircraft weight play in performance?

Aircraft weight affects takeoff distance, climb rate, and fuel efficiency. Heavier aircraft require more power and longer runways.

Can you explain how engine efficiency is measured?

Engine efficiency is typically measured by thrust-to-weight ratio and specific fuel consumption, indicating how effectively fuel is converted to thrust.

What are some common issues encountered during test flights?

Common issues include mechanical failures, unexpected aerodynamic behavior, and instrumentation errors that can affect data accuracy.
