Aviatika-MAI-890 is a single seater multipurpose airplane combines the advantages of «ultralights» and of traditional light planes. This plane is made to be used in sport aviation, air tourism, pilot training flights, aerial photographies, patrolling of forests, roads, electric- and pipelines, towage of gliders, etc. One of Aviatika-MAI-890 airplanes application is using for geo-videomonitoring and soil parameters definition.

Performed calculations and static tests provide high strength of the plane, including a force «triangle» to protect pilots in emergency.

The planes can be flown by pilots of any qualification, its flight characteristics allow to perform aerobatics elements. High thrust-to-weight ratio combined with perfect controllability in all channels and an excellent pilot view from the cockpit make the plane extremely safe and pleasant for piloting.

The airplane Aviatika-MAI-890 is designed in accordance with JAR VLA and FAR—23 regulations. At present the planes are certified in France, South African Republic, and in some other countries. December, 1999 Russian Certificate of the Type was obtained.

Aviatika-MAI-890 is a wire-braced with a fabric covering of wings, control surfaces and tail units, with tricycle fixed undercarriage and controllable nose wheel airplane. The planes have a closed cockpit with an excellent pilot view.

The fuselage is made from aluminium tubes. The cockpit is fully enclosed with two doors with glazing made from organic glass. The nose fairing is made from fiberglass.

Wings are wire-braced. Beams are made from aluminium tubes. Ribs are the pressed components, made from aluminium alloy. Wings are fabric covered.

Empennage is strut- and wire-braced, made from fabric covering aluminium tubes.

Landing gear — tricycle. The spring of main gear is made from titanium alloy. Main wheels (tire 300×125) are equiped with brakes. The nose wheel (tire 300×125) is controlled by pedals.

The engines supplier — «AVIAGAMMA Jsc» (Moscow).

Aviatika-MAI-890U is a two-seater version of Aviatika-MAI-890 airplane.

The cockpit is fully enclosed with two doors with glazing made from organic glass. The back panel and cabin roof from within is covered by a sound-proof material. The double-seater variant is equipped with trim, operated from a cabin. Rotax 912ULS engine (100 h. p.) is installed. The plane can be equipped ski or floats. The structure of the instrument equipment is similar installed on single-seat plane Aviatika-MAI-890 with engine Rotax 912 ULS.

Aviatika-MAI-890SKh — is a crop-sprayer version of Aviatika-MAI-890.

Aviatika-MAI-890SKh is delivered with 105-liter tank for chemicals, filter, control set, rods and bracing wires, shut-off cock, branch pipe, electrical pump with a flowmeter and chemicals’ output counter, atomizers with shut-off valves and flow regulators.

Aviatika-MAI-890USKh can be used for the decision of other tasks:

• initial training of pilots;
• professional selection;
• maintenance of skills of piloting;
• aviatourism;
• patrol;
• geo- video monitoring and etc.

Aviatika-MAI-890USKh is designed on the basis of two-seat plane Aviatika-MAI-890U and has a design similar to it. The structure of the crop-spraying equipment is similar to Aviatika-MAI-890SKh crop-spraying equipment.

One of Aviatika-MAI-890 airplanes employment is using for geo-videomonitoring. A unique geo-videomonitoring system has been installed in the cockpit of one of Aviatika-MAI-890U planes that had been assembled in Aviatika-Ural JSC under licence (see pic. 1). Owing to this system, wich include S-VHS camcorder, VCR and color LCD, an airplane may be used in map-making; ecology-monitoring; making and updating of visual data of buildings, edifices and equipment condition; land-tenure inspection, etc. With a help of built-in GPS aerial system ensure a precise accord every frame to a geography coordinates. An information is showed in a digital form. The following editing of images on PC (with the help of programs AV Master, Erdas, ArcInfo, ArcView, etc.) vidio transforms into the bit-map picture.

An example of operating of this system you can see at picture. This is the image of part of Kochnevo settlement. The survey was made during Aviatika-MAI-890U flight. Altitude is 150 m.; focus is 6 mm.

Next image is a plan of the settlement, that was made from geo-videomonitoring frames.

Aviatika-MAI-890 airplane with a special suspended equipment was used for soil parameters definition. At the next pics you can see results of the same operating near Rzhev. These maps of temperature, dampness and moisture content in the soil is a very valuable information for agriculture.

It's evidently gifficult to me to be objective because I've been working with this airplane about 12 years. However, as a test-pilot, I consider that there are no airplanes better than Aviatika-MAI-890: safety design (it is being produced by the Russian aviation plant together with MIG fighters), perfect controllability, excellent take-off and landing characteristics; this plane can execute difficult aerobatics evolutions... It's a great plane!
 

I can't tell you how much I appreciate my aircraft: the way it is built, the materials used for its construction, the maneuverability and power it is capable of showing. I believe it is the best legal ultralight one could find on the market!
 

It's a great plane; I'm so happy of my purchase!
 

Training air force regiments need this small plane instead expensive jet trainer aircraft. After mastering this plane during several flights, student may begin studing at fighters. I think Air Force High Command should look attentively at Aviatika-MAI-890.
 

(About Aviatika-MAI-890): This is the best plane that I have piloted ever!
 

I flew the Aviatika-MAI-890U in South Africa. I was impressed by the solid construction and the ease of flying. The most important aspect is the price as there are a lot of new aircraft but too expensive in relation to the cost of old Pipers, Cessnas etc. The Aviatika could be a good fun and working aircraft for Australia.
