How can turbulence be detected during flight?

Detecting turbulence during flight can be effectively accomplished through various methods, among which the observation of changes in altitude, fluctuations in airspeed, and reports from other pilots play a crucial role.

When an aircraft encounters turbulence, it may experience sudden changes in altitude as it moves through unstable air patterns. Pilots often feel the aircraft bouncing or vibrating, which corresponds with these altitude shifts. Additionally, fluctuations in airspeed can occur due to the varying forces acting on the aircraft. When the aircraft enters a turbulent area, the airspeed can momentarily increase or decrease, reflecting the unevenness of the airflow.

Pilot reports, or PIREPs, are invaluable in providing real-time information about turbulence from other pilots who have recently traversed the same airspace. These reports help in assessing the intensity and location of turbulence, which can enhance situational awareness for other pilots in the area.

In contrast, while onboard radar systems are useful for identifying weather patterns and precipitation, they do not solely inform about turbulence, as turbulence can occur outside of storm systems as well. GPS data serves primarily for navigation purposes and doesn’t provide information regarding turbulence. Observing ground weather conditions can give some insights, but it's not a direct method of detecting turbulence during flight since it may not
