Robinson R44 Cadet · Other Documents
Overview
This document provides the weight and balance information for the Robinson R44 Raven II helicopter. It is intended for use by pilots and instructors to ensure safe loading and balance of the aircraft. The document includes details on longitudinal and lateral center of gravity (CG) calculations, which are critical for maintaining the aircraft's stability and performance during flight. Proper weight and balance is essential for compliance with safety regulations and for optimizing flight characteristics.
- The R44 Raven II's empty weight and balance must be calculated before flight to ensure safety.
- Longitudinal CG calculations include various configurations such as front pilot, passengers, and baggage.
- Lateral CG must also be assessed to maintain stability, with specific weights and arms for each seating arrangement.
- Fuel load significantly affects both longitudinal and lateral CG, requiring careful calculation.
- Pilots must ensure the aircraft is within specified weight limits for safe operation.

Longitudinal CG
This section outlines the longitudinal center of gravity (CG) calculations for the R44 Raven II. It lists the weights and arms for various configurations, including empty weight, front pilot and passenger, rear passenger with baggage, and fuel configurations. The total CG is calculated with and without fuel, which is crucial for ensuring the aircraft is within safe operating limits.
Lateral CG
The lateral CG section provides similar calculations for the lateral balance of the R44 Raven II. It includes weights and arms for the pilot, passengers, and baggage on both sides of the helicopter. The total lateral CG is also calculated with and without fuel, which is important for maintaining lateral stability during flight.
Safety notes
- Improper weight and balance can lead to loss of control during flight.
- Always verify CG calculations before flight, especially with varying passenger and baggage loads.
