What is the minimum permissible fuel for go-around in each wing?

The minimum permissible fuel for go-around in each wing is 600 lbs. This limitation is in place to ensure that the aircraft has an adequate fuel reserve to safely execute a go-around maneuver if required during landing. The 600 lbs per wing allows for sufficient fuel to maintain optimal engine performance and support necessary flight maneuvers, providing a buffer against fuel starvation during critical phases of flight.

This fuel reserve is essential for ensuring safety margins are met, particularly in scenarios where an immediate go-around might be necessary, such as when the landing approach is compromised or when there are obstacles on the runway. Having the stipulated amount of fuel helps ensure that each engine can operate effectively without the risk of fuel exhaustion during the climb-out after aborting the landing. Without this minimum fuel requirement, the aircraft could face serious operational risks if a go-around is needed.

Other choices do not meet the safety standards set for the CRJ 900, emphasizing why the 600 lbs requirement is critical for safe aviation operations.
