On aircraft, fairings are commonly found on:
- Belly fairing
- Also called a "ventral fairing", it is located on the underside of the fuselage between the main wings. It can also cover additional cargo storage or fuel tanks.
- Cockpit fairing
- Also called a "cockpit pod", it protects the crew on ultralight trikes. Commonly made from fiberglass, it may also incorporate a windshield.
- Elevator and horizontal stabilizer tips
- Elevator and stabilizer tips fairings smooth out airflow at the tips.
- Engine cowlings
- Engine cowlings reduce parasitic drag by reducing the surface area, having a smooth surface and thus leading to laminar flow, and having a nose cone shape, which prevents early flow separation. The inlet and the nozzle in combination lead to an isotropic speed reduction around the cooling fins and due to the speed-squared law to a reduction in cooling drag.
- Fin and rudder tips fairings
- reduce drag at low angles of attack, but also reduce the stall angle, so the fairing of control surface tips depends on the application.
- smooth the airflow at the junction between two components like fuselage and wing, or fuselage and fin.
- Fixed landing gear junctions
- Landing gear fairings reduce drag at these junctions.
- Flap track fairings
- Most jet airliners have a cruising speed between Mach 0.8 and 0.85. For aircraft operating in the transonic regime (about Mach 0.8–1.2), wave drag can be minimized by having a cross-sectional area which changes smoothly along the length of the aircraft. This is known as the area rule. On subsonic aircraft such as jet airliners, this can be achieved by the addition of smooth pods on the trailing edges of the wings. These pods are known as anti-shock bodies, Küchemann Carrots, or flap track fairings, as they enclose the mechanisms for deploying the wing flaps.
- To cover and streamline the propeller hub.
- Strut-to-wing and strut-to-fuselage junctions
- Strut end fairings reduce drag at these junctions.
- Tail cones
- Tail cones reduce the form drag of the fuselage, by recovering the pressure behind it. For the design speed they add no friction drag.
- Wing root
- Wing roots are often faired to reduce interference drag between the wing and the fuselage. On top and below the wing it consists of small rounded edge to reduce the surface and such friction drag. At the leading and trailing edge it consists of much larger taper and smooths out the pressure differences: High pressure at the leading and trailing edge, low pressure on top of the wing and around the fuselage.
- Wing tips
- Wing tips are often formed as complex shapes to reduce vortex generation and so also drag, especially at low speed.
- Wheels on fixed gear aircraft
- Wheel fairings are often called "wheel pants", "speed fairings" or, in the United Kingdom, "wheel spats". These fairings are a trade-off in advantages, as they increase the frontal and surface area, but also provide a smooth surface, a faired nose and tail for laminar flow, in an attempt to reduce the turbulence created by the round wheel and its associated gear legs and brakes. They also have the important function of preventing mud and stones from being thrown upwards against the wings or fuselage, or into the propeller on a pusher craft.
