AIRCRAFT SYSTEMS [SYSTEMS] are used to define which aircraft systems, components or structures are to be monitored on an aircraft. This is where you identify each functional or structural part of the aircraft and define its tolerance to damage. In its most general form, a system entry will look like this ... [SYSTEMS]    system.number=%system_name.number%,system strength,system ID tag or,    system.number=name,system strength,system ID tag where,    "name" is any name you choose to identify the aircraft system, component or structure. Here's an example ... [SYSTEMS] system.0=%system_name.0%,700,0 system.1=%system_name.1%,400,2 etc. ...... or, system.0=Prop Hub/Engine Gearbox,700,0 system.1=Cowl Flaps,400,2 etc. ...... The parameters (separated by commas) are ... system.0=%system_name.0%,700,0 System number. References the aircraft system from within the DP file. System numbers begin with "0" and continue in order for as many systems, components, or structures as you need to define. system.0=%system_name.0%,700,0 System name (for user convenience only). CFS2 uses the system name when generating damage messages, like "Klondike 4 hit your Nose Structure!" If you use the placeholder, "%system_name.number%" here, CFS2 will replace it with the name you defined in [STRINGS] for this system number. In Flerk's Corsair for example, CFS2 automatically replaces the string %system_name.0% with the string Prop Hub/Engine Gearbox. system.0=%system_name.0%,700,0 system strength. The measure of an aircraft system's tolerance to damage. Every time this component is hit, its system strength is decreased by some amount to reflect damage. When this value reaches zero, the system fails. This is a relative measure of damage tolerance. The larger the number, the greater the system's tolerance to damage. How much the system strength is decreased per hit depends on the damage potential of the round passing through the damage box containing this system. The more damaging the round, the more points that are removed for each hit. NOTE You can map multiple components to a single aircraft system. You could, for example, define an engine oil tank plus left and right oil coolers for your aircraft, each mapped to a different damage box, but all of which are mapped to the "Oil Reservoir" system (ID = 2). Each component could have a different system name and each could have a different system strength, but damaging any of them will affect the "Oil Reservoir" system. This way, hitting either oil cooler or both will degrade or fail the entire oil system. system.0=%system_name.0%,700,0 System ID tag. Used to reference the system function within the CFS2 program. When any aircraft system identified by this ID tag takes damage, CFS2 degrades that system's performance.
