FAQ
Frequently Asked Questions
No, it is a highly specialized technical term used almost exclusively in aerospace engineering.
'Fly-by-wire' (using electronic signals) preceded it. Before that, aircraft used mechanical or hydraulic control systems.
No. It functions only as a compound noun (e.g., 'a fly-by-light system') or a noun used attributively (e.g., 'fly-by-light technology').
No. While weight reduction is a benefit, 'light' here refers to light (photons) used in optical fibre data transmission.
An aviation technology where flight control systems use fiber-optic cables instead of traditional mechanical or electrical wires to transmit signals between the pilot's controls and the aircraft's control surfaces.
Fly-by-light is usually highly technical/specialized in register.
Fly-by-light: in British English it is pronounced /ˌflaɪ baɪ ˈlaɪt/, and in American English it is pronounced /ˌflaɪ baɪ ˈlaɪt/. Tap the audio buttons above to hear it.

Learning
Memory Aids
Mnemonic
Think of a pilot's control stick sending signals as beams of LIGHT through thin glass fibers (like fibre-optic internet) to move the aircraft's wings, instead of heavy wires.
Conceptual Metaphor
NERVES OF LIGHT: The aircraft's control system is metaphorically its nervous system, and fly-by-light represents nerves made of pure light for faster, cleaner communication.
