A Cessna 182 is 22 knots faster than a Cessna 172 in terms of cruise speed.
The primary factor contributing to this speed difference is the more powerful engine found in the Cessna 182. While the Cessna 172 is equipped with a 160 horsepower (HP) engine, the Cessna 182 boasts a more robust 230 HP engine. This significant increase in horsepower directly translates to enhanced performance, allowing the 182 to achieve a higher cruise speed.
Performance Comparison: Cessna 172 vs. Cessna 182
To illustrate the difference more clearly, here's a direct comparison of their key performance metrics related to speed and power:
| Feature | Cessna 172 | Cessna 182 |
|---|---|---|
| Engine Power | 160 HP | 230 HP |
| Cruise Speed | 122 knots | 144 knots |
Why the Cessna 182 is Faster
The additional 70 horsepower in the Cessna 182's engine provides several advantages that contribute to its superior speed:
- Increased Thrust: More horsepower means the engine can generate greater thrust, propelling the aircraft through the air at a faster rate.
- Better Power-to-Weight Ratio: Despite being a slightly larger aircraft, the 182's substantial engine power gives it a better power-to-weight ratio, allowing for more efficient acceleration and higher sustained speeds.
- Aerodynamic Efficiency: While both aircraft are designed for general aviation, the extra power of the 182 enables it to overcome drag more effectively, maintaining higher speeds with relative ease.
This difference in speed makes the Cessna 182 a preferred choice for pilots who prioritize quicker travel times or require more robust performance for various operational needs, such as carrying heavier loads or flying in more challenging conditions.
