Morane-Saulnier Alcyon

The Morane-Saulnier Alcyon (en: Kingfisher) is a two or three-seat basic training monoplane designed and built in France by Morane-Saulnier.

Design and development

Designed as a basic trainer for the French military the prototype MS.730 first flew on the 11 August 1949. The prototype was a low-wing cantilever monoplane with a fixed tailwheel landing gear and powered by a 240 hp (134 kW) Mathis 8G.20 inverted V8 engine. The engine was replaced with a German war-surplus 240 hp (179 kW) Argus As 10 and the prototype flew again in November 1949 as the MS.731. Two further prototypes were built and flown in 1951 designated MS.732, they were each powered by a Potez 6D 02 engine and the original fixed landing gear of the prototype was replaced with retractable main wheels.

Operational history

The production version followed designated the MS.733, with five pre-production aircraft and 200 production aircraft. The aircraft were delivered to the French Navy (40), the French Air Force (145) and the Cambodian Air Force (15). Seventy of the French Air Force aircraft were fitted with machine guns for gunnery training and some of these were later converted for counter-insurgency operations (and re-designated MS.733A) for use in Algeria. After the war, some aircraft were sold to Morocco.

The Alcyon was a successful trainer, capable of basic aerobatic maneuvers. It was often used in replacement of pre-war vintage Stampe SV.4 biplanes. Several civilian flying schools, including Air France, used the Alcyon. For the time, it was well equipped with full IFR equipment: two VOR-ILS sets, one ADF set, two VHF radios, a radar altimeter, an attitude indicator, and a directional gyroscope. For this reason, it was often used for navigation training as it was far cheaper to operate than the twin-engine designs commonly used for that task.

Since retirement by the French military services, several Alcyons have been restored to flying condition in France by private pilot owners and groups.

Variants

  • MS.730 : Prototype powered by a 240 hp (134kW) Mathis 8G.20 engine, one built later re-engined as the MS.731.

    • The COIN upgrade included a SFOM 83 reflector sight (suspended from the cockpit roof), two x 7.5mm MAC 1934/M39 machine guns in the wings (with 500 rounds each), and two under-wing hardpoints.
    • Typical hardpoint loadout used paired Matra Type 14 rocket rails, which held four (stacked 2 x 2) SERAM 28 kg.[62 lb.] T10 heavy rockets and had a smaller hardpoint between the rocket rails rated for a 50 kg. [110 lb.] bomb.

    General comments are accessed via the "BLOG En" button.

    Comments are moderated, so please allow some delay before they appear, specially if you are outside Europe.

    Menus are developing below the page, because they are too long!

    I see adds on all videos.

    Use a good free add remover software.

    The site is loading random pages at startup.

    We think it is a good way to bring back the memory of aircraft, persons or events sometimes quite forgotten.

    HELP PAGE

    Why this site?

    Discovery

    This website is dedicated to one's aeronautical passion (which I hope we share) and was realised mainly as an educationnal tool. Knowing that, you'll notice that each new visit brings random topics for the purpose of making new discoveries, some achievements or characters certainly not deserving the oblivion into which they have sometimes fallen.

    By these pages, we also want to pay tribute to all those who gave at one time or another, their lives or health in the name of freedom, aeronautical security or simply our comfort.

    Centralisation

    Internet is full of websites dedicated to aviation, but most are dedicated to subjects or periods that are very limited in space or time. The purpose of this site is to be as general as possible and thus treats all events as well as characters of all stripes and times while putting much emphasis on the most significant achievements.

    The same years saw birth of technologies like photography and cinema, thus permitting illustration of a large part of important aeronautical events from the start. Countless (and sometimes rare) media recently put online by enthousiasts finally give us access to these treasures, but the huge amount of information often makes things a little messy. A centralization effort is obviously most needed at this level.

    All persons who directly or indirectly contributed to the achievement or posting of such documents are here gratefully acknowledged.

    Website layout

    Left menus

    Because of the lack of space on smartphones and small tablets, these menus are hidden. Everything is nevertheless accessible via the main menu option, located between the video and photo sections. This menu is placed there for compatibility reasons with some browsers, which play the videos over the menus.

    "Search" and "Latest" :
    The link "In Titles" restricts the search to the titles of different forms. Use this option if you are looking for a plane, a constructor, a pilot or a particular event that could have been treated as a subject.

    The link "In Stories" will bring you to a search in all texts (the "Story" tab) and will take more time. The search term will appear highlighted in green when opening the corresponding story.

    Would you believe, "Timeline" will show all subjects in chronological order.

    "Random" will reload the entire page with a new random topic.

    The bottom section keeps you abreast of the latest five entries. New topics are added regularly. Don't hesitate to come visit us often : add bookmark.

    Blogs and Comments central section

    Under the photos section comes the comments tabs window :

    You can enter general comments in your own language via one of the two buttons on the left (BLOG EN and BLOG FR). Note that these buttons are accessible regardless of the language to allow some participation in the other language.

    All comments are subject to moderation and will be published only if they comply with the basic rules of decorum, while remaining relevant to the purpose of this site.

    The third tab allows you to enter comments on the shown topic and is bilingual. Personal anecdotes, supplements and other information questions will take place here.

    The "Story" tab shows the explanatory texts. They are most often taken from Wikipedia, a site where we participate regularly.

    The "Data" tab is reserved for list of features and specifications.

    Right menus

    On a smartphone, the lack of space is growing and this menu is moved to the bottom of the page to give priority to videos and pictures.

    The top right icons are links to videos posted by third parties (on their own responsabilities) or by ourselves. The link below these icons will take you to the channel of the one who posted the video. Feel free to suggest other videos if you think they are of some interest (Use the BLOG button or the "Contact" link).
