Final answer:
Pilots should perform landing checks before intercepting the glide path during a PAR approach, ensuring that they can focus on the approach and landing without the distraction of checklists.
Step-by-step explanation:
When conducting a PAR approach using an incomplete pattern, pilots are advised to perform landing checks before intercepting the glide path. This timing ensures that all necessary checks and configurations are completed prior to the critical phase of the approach, allowing the pilot to focus on following the controller's guidance to maintain the correct approach path. It is important to complete these checks early, as the workload will significantly increase once on the glide path, leaving less capacity for attending to checklists.
