Overview of the Project: (5 to 6 lines):-

In this project, the code for controlling the retraction and extension of an airplane’s landing gear is implemented. The pilot’s lever, squat switch, direction valve, limit switch, and light status are used as input for the code. The gear state is then determined and the decision is made to either raise or lower the gear accordingly. The code then implements the necessary actions to raise or lower the gear and displays the result.

Goals ( 2 to 3 points):-

• Implement the code to control the retraction and extension of an airplane’s landing gear.

• Determine the gear state and make decisions to raise or lower the gear accordingly.

• Display the results of the code.

Key Highlights of the Project: (4 to 5 points):-

• Pilot’s lever, squat switch, direction valve, limit switch and light status are used as input for the code.

• The gear state is determined by the limit switch.

• The code checks the conditions before taking off and landing and displays the appropriate light status.

• The code implements the necessary actions to raise or lower the gear.

• The code displays the results of the code.

Deliverables of this project: (4 to 5 points):-

• Coding for the retraction and extension of an airplane’s landing gear.

• Decision-making algorithm for the code.

• Inputs and outputs of the code.

• Flowchart or diagram of the code.

• Testing and debugging of the code.

Expected Outcomes: (4 to 5 points):-

• Successful implementation of the code for the retraction and extension of an airplane’s landing gear.

• Accurate decision-making algorithm based on the inputs given.

• Appropriate inputs and outputs of the code.

• Flowchart or diagram to represent the logic of the code.

• Error-free code with successful testing and debugging.
