How long can a reciprocating engine starter crank continuously?

One minute
Two minutes
Three minutes
Four minutes

The correct answer is: One minute

The correct response is based on the manufacturer’s recommendations and typical operational practices regarding the continuous cranking time for a reciprocating engine starter. Generally, engine starters are not designed to crank indefinitely, as prolonged cranking can lead to overheating and potential damage to the starter motor and the engine's electrical system. One minute of continuous cranking is the common limit for many reciprocating engine starters to ensure safe operation and to prevent overheating. After reaching this limit, it is advisable to allow sufficient cooling time before attempting to crank the engine again. This practice helps to prolong the life of the starter and ensures reliable ignition of the engine. Understanding these operational limits is crucial for effective aircraft maintenance and management, ensuring that both the engine starter and the engine operate within safe parameters.
