spring metal landing gear of a fixed undercarriage
Nosewheel airplanes have the "third" wheel in front of the main landing gear (i.e., under the nose) as pictured below.

 


undercarriage - The part of an aircraft that provides support while the aircraft is on the ground. It includes wheels, shock absorbers and support struts.

Undercarriage - A term used to describe an airplane's entire landing gear.
Useful load - Weight of the occupants, baggage, usable fuel, and drainable oil. The difference between maximum and empty weight.

UNDERCARRIAGE - The landing gear of a land-based aircraft, including struts, frames, and wheels.
UNDERSHOOT - To land short of a runwway or planned landing spot. Opposite is OVERSHOOT.

Undercarriage: The main alighting gear of an aeroplane or floatplane. Modern undercarriages are usually retractable to reduce drag.

Undercarriage with two or more wheel pairs
booms
Braced structural members extending forward and aft of wings to carry foreplanes or tail surfaces ...

UNDERCARRIAGE STRUT
A part of an airplane`s structure, designed to resist distortion, which supports the landing gear.

Fuel
Hatches and Harnesses

These provide only the bare minimum of pre-landing checks, but a more complete list doesn't provide a neat acronym.

Landing Gear, Chassis or Undercarriage.-The wheels and the struts and wires by which they are attached to the fuselage.
9. Horizontal Stabilizer or Horizontal Fin.-The horizontal fixed tail plane.
10. Vertical Stabilizer or Vertical Fin.

The landing gear, the undercarriage assembly that supports an aircraft when it is on the ground, consists of wheels, tires, brakes, shocks, axles and other support structures.

The aircraft was originally designed with a tail wheel undercarriage and the first four prototypes (Me 262 V1-V4) were built with this configuration, but it was discovered on an early test run that the engines and wings "blanked" the stabilizers, ...

Glenn Curtiss had designed a plane that could take off and land on water and thus could be built larger than any plane to date, because it did not need the heavy undercarriage required for landing on hard ground.

clean - flaps, slats and undercarriage retracted and on military aircraft no external missliles etc.

With the flight experience gained on Lilienthal's glider, Pilcher built several others, including the Hawk, which included a tail unit with a hinged surface controlled by the pilot and a wheeled undercarriage with dampening springs to absorb landing ...

An alternative, simple and rapid method of weight estimation of the aircraft is to attach strain gauges on carefully selected spots on the undercarriage supports and calibrating these for the weight of airplane as well as its distribution.

This photo shows the standard Viper installation. It has a fixed-pitch wood propeller, short exhaust pipes and a wooden undercarriage.

Landing Gear The assemblies that include the wheels and the wheel struts. The word "gear" is used in the sense of "equipment", as opposed to the "toothed wheel" meaning of "gear". The British call the landing gear the "undercarriage".
