How Does a Plane Get Out of a Hangar?

Aviation technicians and enthusiasts often wonder how planes, especially small and large aircraft, are maneuvered out of hangars. The process involves a variety of techniques depending on the type of aircraft and the space available in the hangar.

Small Tricycle Gear Planes

For a small tricycle gear airplane like the Cessna 172, getting out of a hangar can be a straightforward process. This method is particularly useful in hangars where space is limited or where the hangar door opening may not accommodate the full length of the aircraft. Generally, the plane can be pushed or pulled using a tow bar that attaches to the nose gear strut. A tow bar serves several purposes:

It provides a stable connection point for the aircraft to be pushed or pulled. It allows the operator to steer the plane, which is much easier than relying on multiple personnel to push on the wings and pull the tail.

Smaller tricycle gear airplanes can sometimes be moved out of a hangar by hand, without the use of a tow bar. However, using a tow bar is highly recommended as it significantly eases the process and ensures better control of the aircraft during movement.

Larger Tricycle Gear Planes

Larger tricycle gear planes require more robust equipment to be moved efficiently. Motorized variants like electric tow bars and full-fledged tugs are commonly used. These devices not only provide a stable connection and steering mechanism but also help in managing the increased mass and momentum of the aircraft. Tugs can be particularly useful in situations where the hangar space is limited, and the aircraft needs to be quickly moved out of the hangar without compromising safety and operational efficiency.

Tail Wheel Aircraft

Tail wheel aircraft, also known as tail-draggers, offer a different approach to maneuvering out of hangars. Unlike tricycle gear planes, tail wheel aircraft are controlled by a person at the tail who can push or pull the aircraft as needed. Steering is achieved by moving the tail left or right. While there are fewer large tail-draggers in service, this method remains a viable option for smaller and vintage aircraft.

Engine Movement

In some cases, especially with tail-in aircraft, the engine can be fired up to motor the plane out of the hangar. However, this method is not the most preferred due to the potential risk of engine blast. Proper protective measures must be in place, and the decision to use this method should be carefully considered based on the specific circumstances and safety protocols.

Alternative Methods

For smaller planes, alternative methods such as manual pushing or pulling can be effective. For larger planes, specialized equipment like large tugs or tractors is essential to handle the weight and size of the aircraft. Motorized tow bars and tugs ensure efficient and safe movement of the aircraft from the hangar and into the runway or taxiway.

Conclusion: The method of moving an aircraft out of a hangar depends on the aircraft type, hangar size, and available equipment. Whether it's a small tricycle gear plane, a larger tricycle gear aircraft, or a tail wheel aircraft, there are reliable and safe methods to ensure the aircraft is moved out smoothly and efficiently.
