- Contexto
- The presence of anomalous meteorological conditions can be reasonably determined by monitoring the outside air temperature (OAT) using the helicopter onboard temperature gauge. Anomalous conditions which could impact the measured levels can be expected to exist when the OAT at 150 m (492 ft) is higher than the temperature measured at a height between 1.2 m (4 ft) and 10 m (33 ft) above the ground by more than 2°C (3.6ºF). This check should be made in level flight at a height of 150 m (492 ft) within 30 minutes of each noise measurement.
