TOPCAT is an acronym for Take-Off and Landing Performance Calculation Tool and is a highly realistic, easy-to-use planning tool for all serious flight simulator enthusiasts. It brings into a single application all of the calculations required to plan for safe and repeatable take-offs and landings. TOPCAT will provide you, the captain, with Load Sheets, Take-Off and Landing performance analysis, Individual Runway Tables including all relevant speeds (V1, VR and V2), optimum thrust and flaps configurations, de-rated and assumed/flex temperatures and stop margins.

TOPCAT is similar to real-life software and was developed by professional airline pilots.
