Problems solved by technology

[0007] Its disadvantages are: since the pilot and co-pilot control their own landing lights separately, and the right landing light control circuit and the left landing light control circuit are independent of each other, this electrical control system for landing lights is only suitable for dual-pilot flight
If a single pilot can only control the landing lights on one side of the pilot, but cannot control the landing lights on the other side, it does not meet the requirements stipulated in Article 91.407 of CCAR-91-R2 "General Operation and Flight Rules" , so it cannot meet the airworthiness requirements when flying with a single pilot
