Abstract
The Laser True Airspeed System (LATAS) developed by the RAE and RSRE and installed on the RAE HS125 research aircraft has proved exceptionally reliable and rugged. During over two years of varied flight trial experience the experimental equipment has never needed any special treatment. Optical readjustment has only been required on fitting a new laser; the latest installation has been in place 14 months with an average of two flights per week. This demonstrates that commercial ‘fit and forget’ CW Doppler Laser systems are now a practical proposition within the present state of the art.
