64-443: A 3,000 foot crosswind runway, an extension of the main runway to 6,900 feet, an instrument landing approach, and FAA Part 139 certification. Scheduled passenger airline service is unlikely to return to Ocala. In 2004 a $ 1.3 million plan was put in motion to upgrade the apron security system. Ocala International Airport covers 1,532 acres (620  ha ) at an elevation of 90 feet (27 m). It has two asphalt runways: runway 18/36

96-561: A Model 188A, first flew on December 6, 1957, two months ahead of schedule. Lockheed was awarded a type certificate by the Civil Aeronautics Administration (CAA) on 22 August 1958. The first delivery – to Eastern Air Lines – was on October 8, 1958, but it did not enter service until January 12, 1959. In 1957, the United States Navy issued a requirement for an advanced maritime patrol aircraft . Lockheed proposed

160-600: A development of the Electra that was later placed into production as the P-3 Orion, which had much greater success – the Orion has been in continual front-line service for more than 50 years. The Model 188 Electra is a low-wing cantilever monoplane powered by four wing-mounted Allison 501-D13 turboprops. It has a retractable tricycle landing gear and a conventional tail . It has a cockpit crew of three and can carry 66 to 80 passengers in

192-523: A million flights on the route before the type was replaced by Boeing 737-300 and Fokker 100 jets in 1992. The Electra became so iconic on that route that its retirement caused a commotion in Brazil, with extensive press coverage and many special tributes. During the mid-1970s, several secondhand Electras were bought by travel clubs, including Nomads, Adventurers and Shillelaghs. Others were retired from passenger service into air-cargo use, 40 being modified by

224-452: A mixed-class arrangement, although 98 could be carried in a high-density layout. The first variant was the Model 188A, followed by the longer-range 188C with room for 1,000 US gallons (3,800 L) more fuel and maximum take-off weight 15000 KG / 33069 lbs. American Airlines was the launch customer. Eastern Air Lines , Braniff Airways , and Northwest Airlines followed. The Electra suffered

256-539: A subsidiary of Lockheed from 1968 with one or two large doors in the left side of the fuselage and a reinforced cabin floor. Air California and Pacific Southwest Airlines (PSA) were still operating Electras for scheduled passenger service during the late 1970s primarily into the Lake Tahoe Airport located in the Sierra Nevada mountains of California, as this airfield had banned scheduled jet aircraft flights at

320-494: A troubled start. Passengers of early aircraft complained of noise in the cabin forward of the wings, caused by propeller resonance. Lockheed redesigned the engine nacelles , tilting the engines upwards 3°. The changes were incorporated on the production line by mid-1959 or as modification kits for the aircraft already built, and resulted in improved performance and a better ride for passengers. Three aircraft were lost in fatal accidents between February 1959 and March 1960. After

352-561: Is 7,467 by 150 feet (2,276 x 46 m) and runway 8/26 is 3,009 by 50 feet (917 x 15 m). In May 2009 construction began on an air traffic control tower . The tower was certified and staffed as an FAA Level I contract control tower in summer 2010. A new terminal building was completed in the spring of 2020. Current facilities on site include: For the year ending October 31, 2022 the airport had 58,465 aircraft operations, average 160 per day: 95% general aviation , 3% air taxi , 1% military , and <1% commercial . 146 aircraft were then based at

384-472: Is an American turboprop airliner built by Lockheed . First flown in 1957, it was the first large turboprop airliner built in the United States. With its fairly high power-to-weight ratio , huge propellers and very short wings (resulting in the majority of the wingspan being enveloped in propwash ), large Fowler flaps which significantly increased effective wing area when extended, and four-engined design,

416-497: The Lockheed C-130 Hercules military transport. The airframe was stretched to allow for more seats and handle the increased performance. This design was launched as the Model 188 with an order for 35 by American Airlines on June 8, 1955. This was followed by Eastern Air Lines with an order for 40 on September 27, 1955. The first aircraft took 26 months to complete, and by that time Lockheed had orders for 129. The prototype,

448-605: The 21st century. The airframe was also used as the basis for the Lockheed P-3 Orion maritime patrol aircraft. By mid-20th century, Lockheed had established a strong position in commercial airliner production with its piston-engined Constellation series . Further development brought turboprop engines to the Constellation airframe with the Lockheed L-1249 Super Constellation . In 1951, Lockheed

480-609: The American Airlines requirements, but failed to meet those of another interested carrier, Eastern Air Lines . Its requirements were for a longer range, a minimum cruising speed of 350 miles per hour (560 km/h), and increased seating capacity to the 85-to-90-passenger level. Lockheed redesigned the CL-310 to use the Allison 501-D13 turboprop engine, a civilian version of the T56 developed for

512-737: The Argentine Navy's Electras, known locally as L-188E Electron , is preserved at the Argentine Naval Aviation Museum ( Museo de la Aviación Naval ) at Bahía Blanca . By July 2018, only two Electras in the world were transporting cargo, both with Buffalo Airways . Thirteen other aircraft remained in service as air tankers nine with Air Spray ( aerial firefighting ) and four with Buffalo Airways (cargo/bulk fuel and aerial firefighting). As of 2024, no passenger flights are taken on Electras, with Air Spray and Buffalo Airways still operating 13 cargo and firefighting planes. Of

544-599: The Australian mainland state capital cities, and later to Port Moresby , from 1959 until 1971. Ansett had its three Electras converted to freighters in 1970–71 and continued to fly them until 1984. Qantas also operated four Electras on its routes to Hong Kong and Japan, to New Caledonia , and to New Guinea (until the New Guinea route was handed to Ansett and TAA); then later across the Indian Ocean to South Africa, and across

576-491: The CL-303. This newer design was a high-wing type and would allow for 60 to 70 passengers. This design was also shelved for lack of interest from other carriers. The following year, American Airlines revised its requirement to a four-engine design for 75 passengers with 2,000 miles (3,200 km) range. Lockheed proposed a new design, the CL-310 with a low wing and four Rolls-Royce Darts or Napier Elands . The CL-310 design met

608-538: The Electra had highly successful operations, such as those of Lloyd Aéreo Boliviano and Líneas Aéreas Paraguayas ; in both cases, the Electra ensured the airlines' international operations before they started using jets. Most notably, Brazilian flag carrier airline Varig operated flawlessly a fleet of 14 Electras on the extremely busy Rio de Janeiro - São Paulo shuttle service (the so-called Ponte Aérea – or "Air Bridge" in Portuguese) for 30 years, completing over half

640-500: The Tasman in competition with TEAL after that airline became 100% New Zealand-owned. The divestiture of TEAL's 50%-Australian shareholding was itself prompted by the Electra order, as TEAL wanted jet aircraft, but was forced by the Australian government to order Electras in order to standardise with Qantas. Three Qantas Electras were retired in the mid-1960s and the fourth in 1971. Some Electras were sold to South American airlines, where

672-463: The airplane had airfield performance capabilities unmatched by many jet transport aircraft even today—particularly on short runways and high altitude airfields. Initial sales were good, but after two fatal crashes that led to expensive modifications to fix a design defect, no more were ordered. Jet airliners soon supplanted turboprops for many purposes, and many Electras were modified as freighters. Some Electras are still being used in various roles into

768-581: The early 1960s, replacing the previous Taylor Field just southwest of Ocala. Its 5000-ft runway was served by Eastern Airlines , with one Convair 440 flight a day with a routing of Jacksonville (JAX) - Gainesville (GNV) - Ocala (OCF) - Vero Beach (VRB) - Miami (MIA) and return. Eastern later operated Lockheed L-188 Electra turboprop service with the last Electra flight leaving Ocala in 1972. Later scheduled passenger airline service included: The last airline flight left Ocala in 1987 when USAir Express pulled out. Airport facilities were then expanded to include

800-407: The engine mounts and the wing structures supporting the mounts were strengthened, and some of the wing skins were replaced with thicker material. All Electras were modified by the factory at Lockheed's expense, with the modifications taking 20 days for each aircraft. The changes were incorporated in later aircraft as they were built. However, the damage had been done, and the public lost confidence in

864-528: The only European airline to order the type from Lockheed was KLM , which used 12 between September 1959 and January 1969 in Europe and east to Saigon and Kuala Lumpur. In the South Pacific, Tasman Empire Airways Limited (TEAL) and its successor Air New Zealand flew the Electra on trans-Tasman flights. In Australia Trans Australia Airlines (TAA) and Ansett each operated three Electras on trunk routes between

896-506: The outboard engine nacelles. When the oscillation was transmitted to the wings and the flutter frequency decreased to a point where it was resonant with the outer wing panels (at the same frequency, or harmonically related ones), violent up-and-down oscillation increased until the wings would tear off. The company implemented an expensive modification program (the Lockheed Electra Achievement Program, LEAP) in which

928-569: The third crash, the FAA limited the Electra's speed until the cause could be determined. After an extensive investigation, two of the crashes (in September 1959 and March 1960) were found to be caused by an engine-mount problem. The mounting of the gearbox cracked, and the reduced rigidity enabled a phenomenon called "whirl mode flutter" (analogous to the precession of a child's Spinning Top as it slows down, an interaction of propellers with airflow) that affected

960-696: The time. In 1973, the Argentine Navy bought three Electras equipped with cargo doors. These were used during the " Dirty War " to toss political prisoners into the Rio de La Plata in the infamous death flights . The Electras were also used for transport duties during the Falklands War in 1982. In 1983, after the retirement of its last SP-2H Neptune , the Argentine Navy bought further civilian Electra airframes, modified several for maritime patrol , and widely used them until their replacement by P-3s in 1994. One of

992-469: The type. This and the smaller jets that were being introduced eventually relegated Electras to the smallest airlines. Production ended in 1961 after 170 had been built. Losses to Lockheed have been estimated as high as $ 57 million, not counting an additional $ 55 million in lawsuits. Electras continued to carry passengers into the 1990s, but most now in use are freighters. Several airlines in the US flew Electras, but

1024-477: Was approached by Capital Airlines to develop a new turboprop airliner, which was designated the YC-130, but no other carriers had any interest, so the design was dropped. Subsequently, Capital Airlines went on to order 60 British Vickers Viscounts . In 1954, as a result of American Airlines ' interest in developing a twin-engined aircraft, the idea resurfaced and the company offered a twin-engined design now designated
