Operational restriction

Operational requirements

The requirement is for a location with a minimum of obstruction to the hemispheric field of view of the radiometers, preferably away from radio transmitter antennas - the pyranometers (measuring solar radiation) are fitted with obscurers (to mask radiation from large obstructions) and the size of these can be minimized with careful choice of location

The instruments should be horizontal to within 3degrees when the aircraft is flying at the mean angle of attack. Airflow past the radiometer bodies is required to reduce thermal stabilization times.

Certification approvals

Approved by CAA for use on BAe 146-301.
