Project 2 - Implement the Code for controlling the retraction and extension of Airplane’s landing gear

Aim:

In this project, controlling the retraction and extension of Airplane’s landing gear can be implemented using Finite State Machine (FSM).

CONTROLLING DIRECTION VALVE:

• pilot's lever state is lever UP then its will must be direction will be UP
• pilot's lever state is lever DOWN then its will must be direction will be DOWN

CONTROLLING AIRPLANE'S GEAR:

• Limit Switch CLOSED then it is gear is UP
• limit switch OPEND then it is gear is DOWN

A direction valve is controlled by the software to allow the hydraulic pressure to either raise or lower the landing gear.

• Direction valve is DOWN then it will be GEAR DOWN
• Direction vave is UP then it will be Raising gear (Takeoff)
• Control of hydraulic pump for the landing gear part is disable then it will be Gear UP(airborne)
• Direction valve is DOWN then it will be Lowering Gear (Landing)

we have to perfroming the many direction valve controlling:

1. GEAR_DOWN
2. CHECKING_BEFORE TAKE OFF
3. RAISING_GEAR
4. GEAR_UP
5. CHECKING_ BEFORE _LANDING
6. LOWERING_GEAR
