Which of the following is NOT part of the Before Start Checklist in the Warrior PA-28A?

The Before Start Checklist in the Warrior PA-28A is a crucial part of the pre-flight procedure that ensures the aircraft is ready for a safe takeoff. The checklist includes several essential items that must be verified before starting the engine. One of the key components of this checklist is the verification of fuel selector positions, ensuring that the aircraft has adequate fuel supply. Additionally, setting the flaps for takeoff and checking engine oil levels are important to confirm the aircraft's operational readiness.

Trim settings, specifically the trim set for landing, typically falls under the Before Landing or Before Takeoff Checklist rather than the Before Start Checklist. Therefore, it is not relevant to the pre-start checks that are focused on starting the engine and preparing the aircraft for taxiing and takeoff. This distinction helps pilots systematically prepare for flight and ensures that all necessary checks are completed in the appropriate sequence.
