A military version of the ERJ 145 designed for airborne early warning and control.
In aviation, V-speeds are standard terms used to define airspeeds important or useful to the operation of all aircraft.
V1 is the critical engine failure recognition speed or takeoff decision speed. It is the decision speed nominated by the pilot which satisfies all safety rules, and above which the takeoff will continue even if an engine fails. The speed varies among aircraft types and several factors such as aircraft weight, runway length, wing flap setting, engine thrust used and runway surface contamination.
V1 is defined differently in different jurisdictions:
The US Federal Aviation Administration defines it as: V1 means the maximum speed in the takeoff at which the pilot must take the first action (e.g., apply brakes, reduce thrust, deploy speed brakes) to stop the airplane within the accelerate-stop distance. V1 also means the minimum speed in the takeoff, following a failure of the critical engine, at which the pilot can continue the takeoff and achieve the required height above the takeoff surface within the takeoff distance.
Let´s say that this project is “an artistic definition” of what happens after V1 flying MD80 and Embraer 190 for Austral Lineas Aereas.
