Agricultural aviation services are characterised by seasonality related to the plant growth cycle and pest occurrence. In Poland, the dead periods were winter and the summer harvest season. Growing agricultural aviation companies therefore began looking for employment for their crews and aviation equipment during these dead periods. The Arab countries turned out to be such a place, constituting the largest market for Polish agricultural aviation services from the mid-1960s onwards. Many countries in the region had gained independence and were striving to increase agricultural production, both for export and to feed their own populations. The large cotton-growing areas there, at a time when demand was high and cotton was the main export commodity, as in Egypt and Sudan, as well as increasing cereal crops, required the use of greater quantities of aviation equipment.

Local agricultural aviation companies did not yet exist or did not have sufficient equipment and personnel. In Poland at that time, serial production of several types of agricultural aircraft and helicopters had begun, and there was a significant number of trained flying personnel. The periodic invasions of locusts and Quelea birds occurring in these countries required the rapid deployment of additional aircraft, and Polish companies had the equipment and personnel available domestically and could quickly put them to work. Moreover, our An-2 aircraft, with their long range and ability to operate independently in difficult terrain conditions, gave an advantage over small Western-manufactured aircraft. For work abroad, our crews received payment in hard currency (convertible currencies of capitalist countries), though it was significantly lower than for crews from Western countries. Similarly, the requirements regarding living conditions for our crews were not excessive, which made our contracts very price-competitive.
Polish agricultural aviation companies at that time were organisationally linked to aircraft manufacturers (WSK Mielec, WSK Okęcie, WSK Świdnik), which greatly facilitated the rapid acquisition of new equipment, spare parts, overhauls and service personnel. This gave a major advantage over small local firms. These factors therefore favoured the obtaining of foreign contracts. In most of these countries, we operated as subcontractors to local firms during periods of increased demand for work. These firms ensured fuel supplies and maintained contact with crop owners. In Sudan and Egypt, however, operations were conducted independently, relying only on local agents to meet tender requirements. All fuel supplies, transport and financial handling were on the Polish side. In accordance with the rules prevailing at the time, agricultural aviation enterprises as the main service provider could only enter into foreign contracts through foreign trade centrals. For agricultural aviation and the aviation industry, this central was Motoimport and later PHZ Pezetel. When carrying out foreign services, it was necessary to obtain visas and diplomatic clearances for overflight through the territories of countries along the route, permits for aircraft and crew operations in the country where services were performed, customs clearances and provision of financial resources for redeployment and contract start-up, and later collection of payments for work. These matters were handled by Pezetel.
After the political changes of 1989, enterprises could already conduct this scope of work independently. Matters of equipment and crew preparation were the responsibility of the main contractor. During contracts, due to health and accident risks, the team included Polish doctors and representatives of aviation supervision. In 1969, enterprises from COMECON countries concluded the so-called “Bucharest agreement”, which aimed at exchanging experience in technical, operational, training and flight safety matters, as well as providing mutual assistance during peak work periods. Most of these countries used Polish-manufactured equipment for agricultural aviation work. Under this cooperation, Polish aircraft and helicopters repeatedly worked in these countries. Similarly, in situations of greater demand for equipment in “hard currency” countries, aircraft from COMECON countries were contracted for work in Poland. It should be noted that only Poland and, to some extent, Bulgaria provided services in hard currency countries.

The most important, earliest and longest-operating destination for foreign agricultural aviation services was Africa, particularly Egypt and Sudan, where services began in 1967. In Egypt, they lasted until 1991 (24 years) and in Sudan until 2009 (42 years). In both countries in the 1960s, there were large cotton plantations which formed the basis of the economy and exports of these countries. These crops required protection from pests and only aircraft could guarantee it. The emerging local companies did not have sufficient equipment and personnel, while in Poland the production of several types of aircraft had begun and we had a significant number of pilots with experience in performing agricultural aviation services domestically. From 1967, 40-60 aircraft and helicopters participated in annual contracts.
The spraying seasons in Egypt and Sudan did not overlap, which allowed the equipment to be used consecutively in both countries. Work in Egypt lasted from May to August and in Sudan from September to February. Aircraft flew mostly under their own power between Poland and Egypt and Sudan through Europe and the Mediterranean Sea, and further across the Nubian Desert. Initially, a small number of PZL-101 aircraft were sent by sea freight to Alexandria, and a few even by transport aircraft. The destination of the ferry flights was the agricultural aviation technical base in Egypt – Benha, located 50 km north of Cairo, and in Sudan – Hassaheisa, 140 km south of Khartoum. PZL-101 aircraft, after being ferried from Poland, worked in Egypt from May to August, then flew to Sudan where they worked from September to February, and then returned to Egypt where they were prepared for the next season and no longer returned to Poland.
The An-2 aircraft, on the other hand, flew annually as needed to Egypt in May and to Sudan in August and returned to Poland to take part in spring operations domestically. From 1976, after the start of production of the modern and safer PZL-106 Kruk aircraft, these flew to Egypt and gradually replaced the PZL-101 aircraft, which were withdrawn from service and scrapped in Egypt. After 1991, when agricultural operations in Poland and services in Egypt ended, An-2 and PZL-106 aircraft remained in Sudan. Only newly manufactured PZL-106 Kruk BT aircraft (with turbine engine) and An-2s flew from Poland as supplementary aircraft for additional operations. The bases in Egypt and later in Sudan also served as technical support facilities for aircraft flying out to work in Ethiopia or other countries in the region where contracts had been concluded.
When planning group ferry flights, the route was determined, crews and group leaders were assembled. Diplomatic clearances for overflight were sought, visas for crews were arranged, and financial resources were planned for airport fees, fuel, hotels and per diems. Maps and other navigation information for each crew were prepared for the route. These were contained in the so-called navigation folder of the given group, which included, among other things, start and landing procedures for all airports planned for landings and alternates, together with a dictionary of basic radio communication phrases in English. The technical department assigned specific aircraft with sufficient remaining airframe and engine service life, gathered spare parts for the group for the ferry flight and for transport as freight.
The required safety equipment for overwater flights and “desert” rations for the flight between Egypt and Sudan were prepared. Initially these were life jackets and a life raft on the leader’s aircraft, and later immersion suits for each crew member as well as radio beacons to signal the location of a possible aircraft ditching. For flying over the desert, a supply of water, food, and signal flare pistols with cartridges were required. Each participant received a tropical uniform, thermos, etc. The validity of aviation medical examinations and vaccination dates in each participant’s international yellow health book was checked, as well as individual contracts for participation in the assignment.
In addition to aircraft crews, the group included a so-called leader, who was the group commander. This was an experienced pilot with knowledge of radio procedures in English and the ability to act independently in unusual situations. He had many duties. During the flight he conducted navigation and radio communication with air traffic control authorities of the countries and airports on the route and with the group’s aircraft. At airports where groups landed, he contacted airport services, border guards and customs, ordered fuel for the group and other necessary services, filed the flight plan and requested weather reports for the next flight leg, and based on the information obtained, decided on the feasibility of continuing the flight.
He made payments for fuel, oil and landing fees, and organised transport for crews to the hotel. The pilot of one of the aircraft flying in the last position was the so-called vice-leader, whose duty was to replace the leader if he could not perform his function, but also to observe all the group’s aircraft and possibly provide assistance to an aircraft falling behind during the ferry flight or during an emergency landing. A chief technician was designated within the group, who was an experienced aircraft mechanic. He was responsible for the technical condition of the aircraft, conducting their inspections at stopover locations, supervising refuelling with fuel and oil, securing aircraft during stops at airports – anchoring them, fitting covers and control locks. Usually, aircraft flew in groups of 5-6 aircraft of the same type. During ferry flights of single-seat aircraft, the group included at least one An-2, in which the group leader, mechanics for those aircraft, spare parts flew, and a life raft and radio beacon were carried.
Groups of aircraft departed on scheduled dates after customs clearance of the aircraft and transported freight. The ferry flight from Poland to Sudan usually took 8-10 days. A distance of approximately 5,000 km was covered. Ferry flights to Africa took place in summer in good weather conditions along the route. The only threats were variable meteorological conditions over mountains and sandstorms in northern Sudan. Return flights, however, were made in winter months and due to unfavourable weather conditions lasted up to 3-4 weeks. Aircraft engines after a full season showed high oil consumption. In mountainous areas of Bulgaria, Yugoslavia and the Tatras, winter conditions prevailed, with low cloud ceilings and icing risks. Group ferry flights were conducted in so-called VFR conditions (with ground visibility) during the day and with mutual visibility – usually at an altitude of about 3,000 m.
Sometimes, in worse atmospheric conditions but with better visibility at lower altitudes, flights were conducted at altitudes of about 150 m above terrain, which however required higher pilot qualifications and somewhat more thorough navigational route preparation. In prolonged bad weather conditions, ferry flights were made by individual aircraft with additionally dispatched pilots holding instrument flight qualifications, i.e., in so-called IFR conditions. However, this significantly increased costs. On the Warsaw – Cairo – Khartoum route, aircraft made intermediate landings for overnight stops and refuelling at airports and desert airstrips. Typically these were: Budapest, Belgrade, Sofia, Thessaloniki, Heraklion in Crete or Larnaca on Rhodes, Alexandria, Benha (agricultural aviation base in Egypt), Luxor, desert airstrips in Sudan – Wadi Halfa, Station 10, and the final destination – Khartoum. From there, after customs clearance and other formalities, the aircraft flew to the agricultural aviation base in Hassaheisa. At the desert airstrips in Sudan, own fuel and oil supplies were sent ahead of ferry flights.
Ferry flights were also carried out on parallel alternative routes depending on actual weather along the route, aircraft type, their navigation equipment, crew qualifications or other circumstances. An event more in the sporting than professional category were the early ferry flights to Egypt and Sudan of PZL-101 Gawron aircraft, particularly across the Mediterranean Sea. These aircraft had no radios and the basic navigation instrument was a KI-13 compass with a 4 cm diameter. During a group ferry flight of 5 aircraft, only the leader aircraft had a radio and the others had to “sit on the leader’s tail” and repeat his manoeuvres. The scale of these operations is demonstrated by the fact that in the peak years of 1976-1989, each spring approximately 40 aircraft were ferried towards Africa, and in winter the same number returned to the country. Newly manufactured aircraft from WSK Okęcie also flew to Egypt during this period. In addition to ferry flights through Egypt, redeployments to other regions were also carried out on the same principles, such as to Iran through the USSR, to Portugal through southern Europe and further to Algeria via Gibraltar.
