Question
Dear Johnson

Is it possible to provide Electronic Security Lock for Aeroplane Ignition system startup with a password?.

Thanks
Prashant

Answer
For small aircraft you could possibly adapt some sort of system to prevent the electrical system from being turned on. However the magnetos for piston engine aircraft generate their own electricity to fire the spark plugs - therefore they don't need a battery to start and run the engine, (i.e you can "hand prop" the engine to get it started).

Large aircraft have a reinforced flight deck door that has a combination lock that could be set to the locked mode. Therefore you would not need it for commercial aircraft.
