Glass Cockpit Display Software Design and Architecture
Added HUD file with some symbology. Trying to create objects for each symbolog. Deciding if structs are better for this.
The glass cockpit display project aims to develop a modern, user-friendly display system for a commercial aircraft, providing real-time information on power levels and the status of the two turbofan motors.
The software will be designed as a multi-layered system, utilizing the capabilities of a glass cockpit display.
This layer provides a graphical user interface (GUI) for the glass cockpit display. It presents flight data and motor information in a visually appealing manner.
- Primary Flight Display (PFD): Displays essential flight information, such as airspeed, altitude, attitude, heading, and power levels of the motors.
- Engine Indication and Crew Alerting System (EICAS): Shows detailed information about the status and power of the turbofan motors.
The application layer manages the data processing and logic required to compute and display motor power levels.
- Motor Data Processing: Collects and processes data from various sensors monitoring the turbofan motors.
- Motor Power Calculation: Computes and updates the real-time power levels based on sensor data.
The HAL interfaces with the aircraft's data acquisition and control systems, providing a unified interface to the application layer.
- Data Acquisition Interface: Collects data from the aircraft's sensors related to the turbofan motors' performance.
- Control Interface: Provides commands to control the display and user interactions.
- User-Centric Design: The graphical interface will be intuitive, easy to read, and visually appealing to enhance pilot situational awareness.
- Real-Time Updates: The glass cockpit display will provide real-time updates of motor power levels, ensuring accurate and up-to-date information for the flight crew.
- Reliability and Redundancy: The software design will include redundant systems and fail-safe mechanisms to ensure reliable operation.
- The Data Acquisition Interface reads sensor data related to the turbofan motors' performance.
- The Motor Data Processing module analyzes the sensor data and prepares it for motor power calculations.
- The Motor Power Calculation module computes the real-time power levels of the two turbofan motors.
- The calculated motor power levels are sent to the Presentation Layer for display on the PFD and EICAS components.
- Data Acquisition Interface API: Provides functions to read sensor data related to the turbofan motors.
- Control Interface API: Offers functions to control the display and user interactions.
- The aircraft is equipped with redundant and fault-tolerant sensors for motor performance monitoring.
- Sensor data is accurate and within acceptable ranges for safe flight operations.
The software design and architecture will adhere to DO-178C guidelines, meeting the appropriate DAL level requirements. The plan includes thorough requirements analysis, detailed design reviews, and comprehensive verification and validation processes, ensuring compliance with aviation safety standards.
Note:
As this example focuses on the glass cockpit display, it emphasizes the presentation and interaction aspects. In a real project, we would need to integrate this software with the aircraft's systems and ensure compliance with DO-178C DAL level requirements, including rigorous testing and certification processes.
