The '''McDonnell Douglas''' (now [[Boeing]]) '''F-15 Eagle''' is an American [[:Category:Twin-engined aircraft|twin-engine]], all-weather tactical [[:Category:Fighter aircraft|fighter]] designed by [[McDonnell Douglas]] to gain and maintain air superiority in aerial combat. Following reviews of proposals, the United States Air Force selected McDonnell Douglas' design in 1967 to meet the service's need for a dedicated air superiority fighter. The Eagle first flew in July 1972, and entered service in 1976.


The Eagle boasts an all-service kill ratio of 104:0. The F-15 downed the majority of Iraqi aircraft in the Gulf War of 1991, and the same in the Balkan conflict of 1999.

== Flight Controls ==
=== {{Abbr|ARI|Aileron Rudder Interconnect}} ===
The {{Abbr|ARI|Aileron Rudder Interconnect}} is a system that automatically applies rudder based on aileron movement (designed to work as an aid as it's what a good pilot should do anyway). The schedule adjusts based on configuration and airspeed. The system is disabled above Mach 0.9 or whenever the landing gear is deployed.
=== {{Abbr|CAS|Control Augmentation System}} ===
The CAS system is a three channel system (Yaw, Pitch, Roll). The YAW channel is basically a yaw damper, the pitch channel is basically a pitch damper and the roll channel is a roll rate limiter. It is not recommended to fly with the YAW CAS channel disabled and is liable to result in serious yaw oscillation at higher mach. If any of these systems are disabled (or inoperative) a warning light will be visible on the caution / warning panel.
=== Pitch Ratio and Roll Ratio ===
The {{Abbr|CADC|Central Air Data Computer}} adjusts the amount of surface movement of the elevator, ailerons and differential elevator per inch of stick movement based on the airspeed to improve the controllability at higher speeds. Both of these systems can be turned off at the roll ratio is on the MISC panel on the left console, the pitch ratio switch is on the centre panel next to the landing gauge. There is also a gauge on this panel which indicates the current pitch ratio either 0.5 in the emergency mode or the value determined by the {{Abbr|CADC|Central Air Data Computer}} .
== Aural Warnings (v1.2f) ==
The following audio warnings are given;
* AOA > 25 (900hz beep beep pause)
* AOA > 30 and gear down (1600hz beeping)
* 85% to 91% of maximum G loading reached (900hz 4 times per second)
* 92% to 95% of maximum G loading (900hz 10 times per second)
* 96% to 100% of maximum G loading (continuous 900hz tone)
* Gear not down when below 200 kts. (900hz beeping)
* Voice warnings for:
# Whenever the Master Caution light illuminates (CAUTION)
# Bingo Fuel
# More than 100% of maximum G loading (OVER-G)
The {{Abbr|OWS|Overload Warning System}} calculates the maximum permissible G loading based upon the current configuration.

When AOA is greater than 20 degrees, or when the gear is down the AOA is displayed, otherwise the Mach number is displayed. The current vertical G loading is displayed, with "NOWS" when the overload warning system is inoperable (which is currently all of the time as this system is not simulated).
When AOA is greater than 20 degrees, or when the gear is down the AOA is displayed, otherwise the Mach number is displayed.  
 
The current vertical G loading is displayed on the bottom left, with the current maximum permitted G loading displayed next to this. If the Overload Warning System is inoperative "NOWS" will be displayed in place of the maximum loading.


The route manager is integrated into the autopilot and when a route is being followed the route manager the routing information will be displayed on the right.
