B737 LANDING PERFORMANCE

Service Description

Description Technological advances have made it possible for performance calculations to be completed with the help of onboard software such as Boeing’s Onboard Performance Tool (OPT). However, overreliance on automated tools can lead to a significant loss of situational awareness and a decrease in our ability to calculate required performance data manually. Lesson 1 Factors affecting landing distance. There are different factors that affect the distance required for landing on the Boeing 737. Changes in these factors either increase or decrease required landing distance. Additionally, inoperative items also affect landing performance in some instances. Objectives By the end of this lesson, the trainee will be able to: • Identify the factors that affect the required landing distance on the Boeing 737. • Analyze how changes in these factors increase or decrease the required landing distance. • Explain the functionality of aircraft systems associated with the landing phase, such as flaps and slats, autobrake and thrust reverser system. Lesson 2 Landing performance calculations – Normal operations Manual landing performance calculations are completed with tables included in the performance section of the quick reference handbook (QRH). The tables are indexed according to the kind of operation (normal or non-normal) and flap selection used for landing. In this lesson, we will only discuss landing distance calculations for normal operations. Objective By the end of this lesson, the trainee will be able to: • Calculate the required landing distance for different airports, aircraft configurations and environmental conditions, during normal operations. Lesson 3 Non-normal operations / threat and error management in landing performance Landing performance calculations are different when non-normal conditions are present. For instance, depending on each failure, QRH procedures will ask pilots to use a specific performance table for landing distance calculations. This lesson will explore landing performance calculations during non-normal procedures as well as the effects of operational threats on landing performance. Objectives By the end of this lesson, the trainee will be able to: • Calculate the required landing distance during a non-normal procedure. • Propose strategies to handle operational threats affecting landing distance.
