How long before last light must a pilot land, according to RMIT SOPs?

According to RMIT SOPs (Standard Operating Procedures), a pilot must complete landing at least 30 minutes prior to last light. This requirement is in place to ensure that pilots can safely execute landing procedures in daylight conditions, when visibility is optimal for judging distances and obstacles.

Landing before last light allows pilots to manage their approach and landing with adequate light, reducing the risk of encountering hazards that may be difficult to see as darkness falls. This practice promotes safety by ensuring that pilot actions, including taxiing and maneuvering on the ground, can be performed in well-lit conditions, as visibility significantly diminishes after sunset.

The choice of 30 minutes serves as a buffer that accounts for potential delays during the landing process, such as traffic at the airport or unexpected weather changes, ensuring that pilots do not risk landing in low visibility conditions.
