Aircraft-set.xml: Difference between revisions

Performance data is advisory : it does not influence the system or FDM simulation in any way. Its purpose is to inform flight-planning and user experience, especially to provide reasonable default values when the user selects starting on approach or in the air. The cruise information is valuable in generating a plausible route between two airports (for example, if Victor or Jet airways should be used), and making a crude estimate of the time enroute based on typically cruising speeds.

The minimum runway length information is valuable in preferring certain airfields when searching locations - for example when using the 777 there is little point in considering a 600ft grass strip.  

Information on aircraft maximums is valuable in the UI to give feedback when the user requests values which exceed aircraft capabilities: for example starting the C172 at 50000ft altitude or 800kts. (Since we're dealing with a flight-simulation situation, we still want to permit such uses, but it's beneficial to be able to warn the user they are doing something which will likely not work well)
