Turbulence detection and mitigation represent significant challenges in aviation, particularly for Advanced Air Mobility (AAM) systems encountering thermal and mechanicalturbulence at low altitudes. Early detection of such flow disturbances is crucial, as it allows for timely evasive manoeuvres or countermeasures to ensure safe operations. While Doppler light detection and ranging (lidar) sensing has been developed for large passenger aircraft, their size, weight, and power requirements has so far limited their utility in AAM vehicles. This paper reviews advancements in airborne Doppler lidar technology and evaluates the trade-offs which promise to enable the miniaturisation of these sensors. A case study is performed to examine the effects of sensor mass and power consumption on the range of three air taxi configurations. Advancements in optical technology are expected to facilitate the integration of efficient, compact lidar sensors into smaller AAM vehicles, enhancing their ability to detect and respond to turbulence, thereby improving their safety.
