Single-Engine V Twin-Engine Helicopters: Which Is Best?

Single-Engine Vs Twin-Engine Helicopters

 

Both single-engine and twin-engine helicopters have unique capabilities and characteristics. Understanding the differences between the two is vital when selecting the most suitable helicopter for your specific private helicopter charter needs.

SHY Aviation’s helicopter charter specialists have many years of experience sourcing the right helicopter for our clients. In this article, they offer their expertise and opinions about which situations best suit which option.

Power and Speed

 

The twin-engine configuration of twin-engine helicopters provides greater power and speed than single-engine options. This additional power is vital on flights that require rapid acceleration and deceleration, and it can also prove beneficial in emergency situations. 

 

Lift Capacity and Payload

 

In general, twin-engine helicopters have greater power, so they can carry more passengers and heavier luggage loads and perform more demanding tasks. In contrast, single-engine helicopters are typically better suited to flights carrying lighter loads, short-distance transfers, and taking off and landing in locations with less available space for manoeuvre.

 

Range and Endurance

 

Due to lower fuel consumption, single-engine helicopters often have superior range and endurance capabilities than twin-engine models. This enables them to fly longer distances, making them a popular choice for helicopter charters requiring extended flight times.

 

Safety

 

A significant safety advantage of twin-engine helicopters is that in the event of an engine failure, the remaining engine can still provide enough power to land the helicopter safely. As a result, only twin-engine helicopters can fly at night, or over water, densely populated areas, or inhospitable terrain. This means twin-engine helicopters provide the greatest flexibility for helicopter charters.

 

Performance in Adverse Conditions

 

Due to their extra power and the additional control and stability they provide, twin-engine helicopters typically perform better in adverse weather conditions and at high altitudes. This makes them the ideal choice for private helicopter transfers to locations such as ski resorts.
