4. LOW COST CIVIL DEFENCE The majority of existing nations have implemented aerial and surface logistics for the rescue and assistance of their citizens in the event of natural disasters, road accidents etc. The type of operational system implemented for civil defense in each nation, is determined by that nation’s financial capacity, topography and territorial area. Nations with the greatest resources employ mainly helicopters for rescue and emergency supplies, these aircraft are the most adequate for the purpose. However helicopters are quite expensive to purchase, operate and maintain, certainly beyond the financial reach of the majority of the nations of the world. In effect, technically and logistically viable alternatives that are cost effective can at present be developed and implemented to provide the required assistance to poorer nations in the field of civil defense. AERIAL LOGISTIC SUPPORT WITH FIXED WING AIRCRAFT Short take off and landing (S.T.O.L.) aircraft provide an interesting and viable alternative to satisfy adequately the functions of aerial rescue and supply at a much lower cost than helicopters. New generation power plants presently available, materials, improved wing design and equipment have contributed to the viability in the development of an effective super STOL category of aircraft. These aircraft have the performance required and design features to realize rescue operations in the absence of landing fields . Aviotec, an aircraft manufacturing company jointly owned by a U.S. partner and Alex Roth located in Santa Cruz, Bolivia; have developed the Aviastol STOL aircraft that is suitable for medi- vac operations. The Aviastol is a turbo prop powered super STOL aircraft, designed to accommodate a patient in its stretcher and capable of landing and takeoff from a rock covered river bank or short clearing in the jungle or savanna OPERATI0NAL AND TECHNICAL MANAGEMENT The administrative and operational control of these medivac aircraft in the civil defense role could be realized by the ministry of defense. Bolivia due to its topography and large territorial area, would require several units. Initially, four units should be assigned to the capital of the most populated regions, La Paz, Cochabamba, Santa Cruz and Tarija in order to reduce to the minimum the operational distance and reaction time. In case of a larger contingency, all four units can be flown to the required location. To optimize the usefulness of these aircraft to the immediate community and also reduce the stand by cost of these units, the air force, police, municipality, national parks, churches etc. would be given access to flight time at an affordable brake even operational cost of $US 80 per hour including $US 20 for pilot. Eight selected pilots from the air force and private sector would be given bush pilot training as well as the paramedic training to eight medical doctors of their respective region. The pilots and medical doctors assigned to the civil defense program would realize their normal daily duties and activities but would be called upon to fulfill their duty in an emergency and thus further reduce the fixed cost.

5. AVIASTOL SR305 S.T.O.L. AIRCRAFT FOR TRANSPORT AND MEDI VAC GENERAL DESCRIPTION Four passenger high wing, conventional tail wheel utility aircraft of mixed construction, tubular structured fuselage, tail empennage, undercarriage and aluminum monocoque wing. FUSELAGE High strength TIG welded 4130 chrome moly tubular structure covered with aluminum panels and polyurethane doped polyester material. Fuselage has provisions to accommodate patient or bulky cargo via direct access through removable turtle deck at upper rear side of the fuselage. Pilot’s adjacent seat is reversible to permit paramedic to assist patient in flight. UNDER CARRIAGE Robust triangular 4130 tubular undercarriage with compression coil spring and hydraulic damper mounted laterally externally for high strength, improved geometrical advantage and minimal rebound. Tundra flotation tires to land over rough surfaces with boulders of up to 8” diameter. TAIL EMPENAGE 4130 steel tubular frame and 4130 channel ribs covered with HD doped polyester fabric. High strength jack trim for effective trim compensation. Elevator actuated by compression - tension aluminum tube with ball bearing mounted bellcrank and rod ends for durability and strength. WING Aluminum monocoque high lift wings NACA 4412 aerofoil for good cruise velocity and low stall. Large flaps and ailerons for short take off and effective low speed control. Drooping ailerons and vortex generators for even better STOL performance. Wings are entirely riveted with solid flush type fasteners. Aluminum single wing strut supports de wing. 50 gals main removable fuel tanks plus 20 gls. Tip tanks NACA 4412, drag lift coefficient 0.4, turbulent boundary layer airfoil. ENGINE LYCOMING IO-540 OR MATTITUCK TMXIO-540 6 cylinders, fuel injected 2000 hrs. TBO, 260 hp. PISTON TURBO DIESEL (suitable for transport, greater range) S.M.A. 230 HP, max power prop rpm 2300, fuel consumption 9 gph at 75% power, 12.5 at 100% power. Specific fuel consumption .33 lbs/hp/hr. T.B.O. 3000 hrs., wt. 196 kls.,435 lbs., fuel control electronic FADEC. Fuel jet A. Oil changes every 50 hrs.

6. AVIASTOLDescription The preproduction Aviastol is a four seats STOL aircraft designed and built by Aviotec. The projected purpose is to develop and eventually produce a quality high performance multi purpose utility bush plane for private transport, mining, farmers, med evac, oil pipes surveillance, parks vigilance, etc. Several improvements and modification have been incorporated to the new preproduction prototype. Some of these are: new monocoque type aluminum wings with NACA 4412 airfoil for improved cruise speed, drooping ailerons, better power to weight ratio, larger cabin interior, high strength lateral mounted coil spring suspension with hydraulic damper that allows the optional cargo pod mounting, etc. The first Aviastol prototype powered with a Franklin 220 hp engine had the purpose of establishing the required modifications and improvements for the upcoming preproduction Aviastol. The production Aviastol will be offered with the following power plants: 260 hp Lycoming, the SMA 305 jet fuel engine or the upcoming 200 hp Delta Hawk diesel engine.
