ForeFlight has released a turbulence-reporting feature that sources information from its Sentry and Sentry+ ADS-B In receivers. The reported turbulence feature captures internal attitude sensor data from the Sentry units when pilots’ iPads are connected to the internet, either in the air if connectivity is available or after landing.
Unlike subjective pilot reports of turbulence, which rely on pilots’ varying perceptions of intensity, the data from the Sentry devices is objective and derived from the units’ sensitive attitude sensors. Traditional turbulence information is based on pilot reports, which are generally biased towards giving more turbulence reports versus fewer smooth air reports, as well as forecast models and winds aloft forecasts, all of which pilots use to try to predict and avoid turbulence while planning flights, according to ForeFlight.
