The term for an airplane on the ground navigating an airstrip or runway is called taxiing. However, this term does not include the high-speed run an aircraft takes on the runway before taking off and the decelerating run just after landing. When moving on a runway, large aircraft are steered with the help of a tiller. An aircraft tiller is a steering wheel in the cockpit that works similarly to a car steering wheel but looks nothing like it. The tiller is actually a small wheel or crank that lies usually to the side of the pilot and can be operated with one hand (two hands are not required) to turn the wheels of an aircraft.

The U.S. military is an organization that produces nearly $41 billion in revenue, has 8 supply chains, and 5 million items. It would make economical sense therefore, for a manufacturer of aerospace and military parts to want to do business with the U.S. military. To do business with the U.S. military however, you must obtain a Commercial and Government Entity Code obtained through the Defense Logistics Agency. Every manufacturer who does business with the military has a CAGE code,a unique 5-digit alphanumeric code. CAGE codes are free and are relatively straight-forward to acquire. Though issued by the U.S. DLA, manufacturers in other countries can be assigned a NATO Commercial and Government Entity Code (NCAGE), which are legitimate under the NATO Codification System (NCS).

Whether you are driving a motorbike, Formula 1 car, or aircraft, one of the things that are you most reliant upon is the braking system. The basic principle of an aircraft braking system is to absorb energy from the moving system in order to slow the moving vehicle down. A key component of most braking systems is the anti-skid system. Skidding is sliding across a surface with little-to-no control. Skidding is often associated with the phrase ‘locked up’, which is in reference to the wheels of the vehicle. In most circumstances skidding in an automobile isn’t a desirable occurrence. In Formula 1 it could lose a race, on an aircraft it could result in an aircraft sliding off a runway.

The distinction between “tailwheel” and “nosewheel” aircraft is the position of the aircraft’s landing gear on its fuselage. An aircraft with a tailwheel is designed with two main landing gear that are placed forward of the aircraft’s center of gravity, or in front of the aircraft, with a single aircraft tailwheel in the rear of the airplane to support the tail. This is different from nosewheel (also called tricycle) landing gear arrangements, where the main wheels are placed behind the center of gravity, and the aircraft nose gear supports it in the front.

If not in flight, any pilot wishes for the aircraft to be on the ground and in the correct place. The last thing any airport worker needs is a runaway plane on the runway. Brakes stop or slow the motion of a machine. Often a machine keeps running and is only stopped from moving forward by pressing on brake pads. For example, in an automatic car, the driver must keep their foot on the brake pedal to stop the car moving forward at a red light or in traffic.
