The autobrake, whose components are located on the center panel of the Main Instrument Panel, is a deceleration feature used by aircraft. It automatically applies brake pressure during landing, allowing for pilots to focus on other tasks during the landing, such as flaring and landing the aircraft, as well as engaging reverse thrust and using rudder to maintain centerline.
Autobrakes function similarly to spoilers; in fact, the autobrake system kicks in after the spoilers deploy, with a slight delay, depending on the setting that the autobrake system is set to (more information later on).
In the real world, lower autobrake settings are used as to preserve tires, brake systems, and runway surfaces. There are higher settings available, which are saved for inclement weather, emergencies, rejected takeoffs, etc. These settings are listed below.
For the purposes of this topic, the Boeing 737 aircraft will be used as an example; different manufacturers and different aircraft types will have different specifications.
|Setting||Pressure Applied||Rate of Deceleration|
|1||1250 PSI||4 ft per second squared|
|2||1500 PSI||5 ft per second squared|
|3||2000 PSI||7.2 ft per second squared|
|MAX||3000 PSI||14 ft per second squared, 12 ft per second squared below 80 knots|
|RTO*||3000 PSI||14 ft per second sqaured above 80 knots, 12 ft per second squared below 80 knots|
Implementation in Infinite Flight
This would be a great feature to have in Infinite Flight, to allow for a smoother landing experience. With the use of autobrakes (which are actually mandated by some airlines for use during all landings), pilots can focus on landing their aircraft smoothly and safely, allowing for a constant rate of deceleration and an efficient arrival. This would operate similar to spoilers, with pilots being able to set autobrakes before landing - they would deploy upon landing, as mentioned before. Settings would be customizable (just as we have spoilers that can be set to flight or armed).
I have attached a mockup below, using the A320 as a test subject. The setting is not modeled to scale, and the autobrake setting is set to MEDIUM.
