Model A

Model A, introduced by Call Aircraft Company in 1978, quickly became a landmark in commercial aviation. Developed during a period of rapid jet propulsion advancements, the aircraft was the first to combine a fully retractable high‑lift wing with a digital flight‑control system, allowing smoother take‑offs and landings on short runways. Its twin‑engine configuration, using the then‑newly released turbofan T‑72, delivered a cruising speed of 540 km/h while consuming 15 percent less fuel than its competitors. The spacious cabin, configured for 150 passengers, featured interchangeable modules that could be changed from standard seating to cargo or medical evacuation layouts within a few hours. Over its 30‑year production run, more than 800 Model A airframes were delivered to airlines across four continents, establishing new standards for reliability and operating cost. The aircraft’s safety record—highlighted by an advanced anti‑icing system and redundant hydraulic circuits—contributed to its reputation as a workhorse for regional carriers. Today, Model A is credited with paving the way for modern blended‑wing designs and remains a reference point in studies of efficient, adaptable air transport. Its legacy continues to influence aircraft designers seeking to balance performance, economy, and environmental responsibility.
