# Aircraft Weight and Balance Checker MCP. AI Agent Connect

> Aircraft Weight and Balance Checker MCP handles the math for takeoff, landing, zero-fuel, and ramp weights. Your AI client uses this tool to check if an aircraft configuration stays within safety boundaries by verifying the center of gravity against specific limits and providing a breakdown of weight distribution across stations.

## Description

You can hand off complex aviation math to your AI client using this MCP. Instead of manually calculating weight distributions, you provide the raw data and let your agent handle the heavy lifting. It calculates critical values like takeoff, landing, zero-fuel, and ramp weights based on your specific aircraft configuration. 

Safety is the priority here. Your agent can verify if a specific loadout is safe by checking the center of gravity against defined safety envelopes. It also provides a clear breakdown of how weight is distributed across different aircraft stations, making it easier to see exactly where the load sits. Whether you are checking if you have enough data to proceed or verifying a final weight calculation, this MCP keeps the math precise and the safety checks consistent.

## Tools

### calculate_weight_and_balance
This tool performs the core weight and balance math for your aircraft.

### check_cg_envelope
Use this to see if your calculated center of gravity stays within safe limits.

### summarize_station_loading
This tool gives you a clear breakdown of weight distribution across all aircraft stations.

### validate_input_completeness
This tool checks your data to ensure you have everything needed for a full calculation.

## Prompt Examples

**Prompt:** 
```
Calculate the weight and balance for an aircraft with an empty weight of 2500, arm of 50, payload of [{'weight': 500, 'arm': 60}], fuel of [{'volume': 200, 'arm': 40}], fuel density of 0.8, and limits: {'maxTakeoffWeight': 4000, 'maxLandingWeight': 3500, 'maxZeroFuelWeight': 3200, 'maxRampWeight': 4100, 'minCG': 45, 'maxCG': 55}.
```

**Response:** 
```
The takeoff weight is 2660, the landing weight is 3000, the zero-fuel weight is 3000, and the center of gravity is 50.5, which is within the envelope.
```

**Prompt:** 
```
Is the center of gravity of 42 within the limits of 45 to 55?
```

**Response:** 
```
No, the center of gravity is outside the safety envelope.
```

**Prompt:** 
```
Check if I have all the data needed for a weight and balance calculation.
```

**Response:** 
```
The provided data is sufficient for a full calculation.
```

## Capabilities

### Weight Calculations
Your agent calculates takeoff, landing, zero-fuel, and ramp weights.

### Safety Envelope Verification
The AI checks if the center of gravity falls within defined safety boundaries.

### Station Loading Summaries
The tool provides a breakdown of how weight is spread across aircraft stations.

## Use Cases

### Pre-flight Verification
A pilot provides payload and fuel numbers to ensure the aircraft is within weight limits.

### Loading Analysis
An engineer checks how specific cargo weights affect the center of gravity.

### Safety Compliance
The agent checks if a calculated center of gravity falls outside the allowed safety envelope.

### Data Auditing
You use the tool to confirm that a flight plan has all the necessary weight data.
