An overview is given of the FBL(Flight\|By\|Light) scheme currently developed for airborne actuation systems. After paralleling the benefits of FBL with demands of the flight control system of future aircraft, the necessity of developing FBL technology is pointed out. Considering the present status of technology and the level of researches on FBL in our country, and balancing the pros and cons of analog and digit FBL schemes, a kind of quasi-digit FBL scheme is put forward. The schematic circuit diagram of V/F E/O and O/E F/V conversion of this scheme is illustrated, which has been demonstrated in laboratories. The frequency bandwidth of the conversion component reaches 500?Hz. The preliminary experiment shows that this quasi digit FBL scheme can meet the needs of future flight control systems and is a reasonable transition to the digit FBL scheme.
