These aircraft are typically <a href="/wiki/Fixed-wing_aircraft" title="Fixed-wing aircraft">fixed-wing</a>, though <a href="/wiki/Amphibious_helicopter" title="Amphibious helicopter">amphibious helicopters</a> do exist as well. Fixed-wing amphibious aircraft are <a href="/wiki/Seaplanes" class="mw-redirect" title="Seaplanes">seaplanes</a> (<a href="/wiki/Flying_boat" title="Flying boat">flying boats</a> and <a href="/wiki/Floatplane" title="Floatplane">floatplanes</a>) which are equipped with <a href="/wiki/Landing_gear" title="Landing gear">retractable wheels</a>, at the expense of extra weight and complexity, plus diminished range and fuel economy compared with planes designed specifically for land-only or water-only operation. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Design">Design</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Amphibious_aircraft&action=edit&section=1" title="Edit section: Design"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><a href="/wiki/Floatplane" title="Floatplane">Floatplanes</a> often have floats that are interchangeable with wheeled <a href="/wiki/Landing_gear" title="Landing gear">landing gear</a> (thereby producing a conventional land-based aircraft). However, in cases where this is not practical, amphibious floatplanes, such as the amphibious version of the <a href="/wiki/De_Havilland_Canada_DHC-3_Otter" title="De Havilland Canada DHC-3 Otter">DHC Otter</a>, incorporate retractable wheels within their floats. Some amphibians are fitted with reinforced <a href="/wiki/Keel" title="Keel">keels</a> which act as skis, allowing them to land on snow or ice with their wheels up. </p><p>Many amphibian aircraft are of the <a href="/wiki/Flying_boat" title="Flying boat">flying boat</a> type. These aircraft, and those designed as floatplanes with a single main float under the fuselage centerline (such as the <a href="/wiki/Loening_OL" title="Loening OL">Loening OL</a> and <a href="/wiki/Grumman_J2F" class="mw-redirect" title="Grumman J2F">Grumman J2F</a>), require outrigger floats to provide lateral stability so as to avoid dipping a wingtip, which can destroy an aircraft if it happens at speed, or can cause the wingtip to fill with water and sink if stationary. While these impose weight and drag, amphibious aircraft also face the possibility of these getting hit when operating from a runway. A common solution is to make them retractable, like those found on the <a href="/wiki/Consolidated_PBY_Catalina" title="Consolidated PBY Catalina">Consolidated Catalina</a>; however, these are even heavier than fixed floats. Some aircraft may have the tip floats removed for extended use from land. Other amphibians, such as the <a href="/wiki/Dornier_Seastar" title="Dornier Seastar">Dornier Seastar</a>, use stub wings, called <a href="/wiki/Sponsons" class="mw-redirect" title="Sponsons">sponsons</a>, mounted with their own lower surfaces nearly even with the ventral "boat-hull"-shaped fuselage surface. This can provide the needed stability, while floatplane amphibians usually avoid the problem by dividing their buoyancy requirements between two floats, much like a <a href="/wiki/Catamaran" title="Catamaran">catamaran</a>. </p><p>Some non-amphibious seaplanes may be mistaken for amphibians (such as the <a href="/wiki/Shin_Meiwa_PS-1" class="mw-redirect" title="Shin Meiwa PS-1">Shin Meiwa PS-1</a>) which carry their own beaching gear. Usually, this is a wheeled dolly or temporary set of wheels used to move a flying boat or floatplane from the water and allow it to be moved around on land. It can also appear as a conventional undercarriage. These are not built to take the impact of the aircraft landing on them. An amphibian can leave the water without anyone getting in the water to attach beaching wheels (or even having to have any handy), yet a fully functional undercarriage is heavy and impacts the aircraft's performance, and is not required in all cases, so an aircraft may be designed to carry its own. </p> <div class="mw-heading mw-heading2"><h2 id="Hazards">Hazards</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Amphibious_aircraft&action=edit&section=2" title="Edit section: Hazards"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>An occasional problem with amphibians is with ensuring that the wheels are in the correct position for landing. In normal operation, the pilot uses a checklist, verifying each item. Since amphibians can land with them up or down though, the pilot must take extra care to ensure that they are correct for the chosen landing place. Landing wheels-up on land may damage the keel (unless done on wet grass, a technique occasionally used by pilots of pure flying boats), while landing wheels-down on water will almost always flip the aircraft upside down, causing substantial damage. </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Vickers_Viking_amphi.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/0/05/Vickers_Viking_amphi.jpg/220px-Vickers_Viking_amphi.jpg" decoding="async" width="220" height="163" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/0/05/Vickers_Viking_amphi.jpg/330px-Vickers_Viking_amphi.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/0/05/Vickers_Viking_amphi.jpg/440px-Vickers_Viking_amphi.jpg 2x" data-file-width="1440" data-file-height="1067" /></a><figcaption>Vickers Viking - an early amphibian.</figcaption></figure> <div class="mw-heading mw-heading2"><h2 id="Usage">Usage</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Amphibious_aircraft&action=edit&section=3" title="Edit section: Usage"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Amphibious aircraft are heavier and slower, more complex and more expensive to purchase and operate than comparable landplanes.

The <a href="/wiki/Grumman" title="Grumman">Grumman</a> Corporation, latecomers to the game, introduced a pair of light utility amphibious aircraft – the <a href="/wiki/Grumman_Goose" class="mw-redirect" title="Grumman Goose">Goose</a> and the <a href="/wiki/Grumman_Widgeon" class="mw-redirect" title="Grumman Widgeon">Widgeon</a> – during the late 1930s for the civilian market. However, their military potential could not be ignored, and many were ordered by the <a href="/wiki/Military_of_the_United_States" class="mw-redirect" title="Military of the United States">US Armed forces</a> and their allies during World War II. Not coincidentally, the <a href="/wiki/Consolidated_Catalina" class="mw-redirect" title="Consolidated Catalina">Consolidated Catalina</a> (named for <a href="/wiki/Santa_Catalina_Island,_California" class="mw-redirect" title="Santa Catalina Island, California">Santa Catalina Island</a> off the coast of southern California, whose resort was popularized partly by the use of amphibians in the 1930s, including Sikorskys and <a href="/wiki/Douglas_Dolphin" title="Douglas Dolphin">Douglas Dolphins</a>) was redeveloped from being a pure flying boat into an amphibian during the war. After the war, the United States military ordered hundreds of the <a href="/wiki/Grumman_Albatross" class="mw-redirect" title="Grumman Albatross">Grumman Albatross</a> and its variants for a variety of roles. However, like the pure flying boat, they were made obsolete by helicopters which could operate in sea conditions far beyond what the best seaplane could manage. </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:PiaggioP136L1Takeoff.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/7/7c/PiaggioP136L1Takeoff.jpg/220px-PiaggioP136L1Takeoff.jpg" decoding="async" width="220" height="130" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/7/7c/PiaggioP136L1Takeoff.jpg/330px-PiaggioP136L1Takeoff.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/7/7c/PiaggioP136L1Takeoff.jpg/440px-PiaggioP136L1Takeoff.jpg 2x" data-file-width="1024" data-file-height="607" /></a><figcaption><a href="/wiki/Italian_Air_Force" title="Italian Air Force">Italian Air Force</a> <a href="/wiki/Piaggio_P.136" title="Piaggio P.136">Piaggio P.136</a> during takeoff, retracting the wheels that make it an amphibian.</figcaption></figure> <p>Development of amphibians was not limited to the United Kingdom and the United States. In any case, few designs saw more than limited service, as there was a widespread preference for pure flying boats and floatplanes, due to the weight penalty the undercarriage imposed. Russia also developed a number of important flying boats, including the widely used pre-war <a href="/wiki/Shavrov_Sh-2" title="Shavrov Sh-2">Shavrov Sh-2</a> utility flying boat, and postwar the <a href="/wiki/Beriev_Be-12" title="Beriev Be-12">Beriev Be-12</a> anti-submarine and maritime patrol amphibian. Development of amphibians continues in Russia with the jet-engined <a href="/wiki/Beriev_Be-200" title="Beriev Be-200">Beriev Be-200</a>. Italy, bordering the <a href="/wiki/Mediterranean_Sea" title="Mediterranean Sea">Mediterranean</a> and <a href="/wiki/Adriatic" class="mw-redirect" title="Adriatic">Adriatic</a>, has had a long history of waterborne aircraft, going back to the first Italian aircraft to fly. While most were not amphibians, quite a few were, including the <a href="/wiki/Savoia-Marchetti_S.56" title="Savoia-Marchetti S.56">Savoia-Marchetti S.56</a>A and the <a href="/wiki/Piaggio_P.136" title="Piaggio P.136">Piaggio P.136</a>. </p><p>Amphibious aircraft have been particularly useful in the unforgiving terrain of <a href="/wiki/Alaska" title="Alaska">Alaska</a> and northern <a href="/wiki/Canada" title="Canada">Canada</a>, where many remain in civilian service, providing remote communities with vital links to the outside world. The <a href="/wiki/Canadian_Vickers_Vedette" title="Canadian Vickers Vedette">Canadian Vickers Vedette</a> was developed for forestry patrol in remote areas; a job that previously was done by canoe and took weeks could be accomplished in hours, revolutionizing forestry conservation. Although successful, flying-boat amphibians like the Vedette ultimately proved less versatile than floatplane amphibians and are no longer as common as they once were. Amphibious floats that could be attached to any aircraft were developed, turning any aircraft into an amphibian, and these continue to be essential for getting into the more remote locations during the summer months when the only areas suitable for landing are the waterways. </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Us-2_03l.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/9/9d/Us-2_03l.jpg/220px-Us-2_03l.jpg" decoding="async" width="220" height="146" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/9/9d/Us-2_03l.jpg/330px-Us-2_03l.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/9/9d/Us-2_03l.jpg/440px-Us-2_03l.jpg 2x" data-file-width="4256" data-file-height="2832" /></a><figcaption><a href="/wiki/ShinMaywa_US-2" title="ShinMaywa US-2">ShinMaywa US-2</a>, developed in the 2000s in Japan from the older <a href="/wiki/Shin_Meiwa_US-1A" title="Shin Meiwa US-1A">Shin Meiwa US-1A</a></figcaption></figure> <p>Despite the gains of amphibious floats, small flying-boat amphibians continued to be developed into the 1960s, with the <a href="/wiki/Republic_Seabee" class="mw-redirect" title="Republic Seabee">Republic Seabee</a> and <a href="/wiki/Lake_LA-4" class="mw-redirect" title="Lake LA-4">Lake LA-4</a> series proving popular, though neither was a commercial success due to factors beyond their makers' control.
