When calculating RTOW, what runway slope should be taken into account?
Understand the Problem
The question is asking for specific guidelines regarding the slope to be considered when calculating the Runway Takeoff Weight (RTOW) for an aircraft. It lists multiple options that pertain to runway slopes in relation to RTOW calculations.
Answer
Consider the mean slope of the runway when calculating RTOW.
When calculating RTOW (Regulatory Take-Off Weight), the mean slope of the runway should be taken into account.
Answer for screen readers
When calculating RTOW (Regulatory Take-Off Weight), the mean slope of the runway should be taken into account.
More Information
The mean slope is used to represent the overall gradient effect of a runway that may have varying slopes along its length. This allows for a standardized calculation of takeoff weight considering the entire runway's slope characteristics.
Tips
A common mistake is ignoring how variable slope conditions across a runway length can impact takeoff performance calculations. Always ensure to account for the mean slope over the entire runway.
