Project 2 - Implement the Code for controlling the retraction and extension of Airplane’s landing gear
Overview of the Project:
In this project, controlling the retraction and extension of Airplane’s landing gear can be implemented using Finite State Machine (FSM). FSM is the most efficient algorithm which is mathematical model of computation. In this project we control the Airplane landing gear by verifying the various parameters for the safety reason. This procudure are follow for proper landing and take off
Goals
- Controlling the direction of Valve.
System directly controll the valve and contol the direction of the wheel by verifiying the other system
- Controlling the retraction and extension of Airplane’s landing gear.
Retraction and extension of Airplane is control by the lever and its check proper hight for landing or takeoff.
A direction valve is controlled by the software to allow the hydraulic pressure to either raise or lower the landing gear.
Deliverables of this project:
Implementing the control for the retraction and extension of Airplane’s landing gear using the Finite state machine with the knowledge of various states of switch and gear.
