airfield was reopened to the public in 1958, but with the growing size of postwar aircraft, Mannheim-Neuostheim was no longer served by any major airline and mainly used for private flying. Development since the 1980s In 1983, a test flight for STOL (short take-off and landing) aircraft took place with a four-engined Dash-7 turboprop aircraft. In 1986, DRF (Deutsche Rettungsflugwacht, e. V.) installed a helicopter air rescue center at MHG. Scheduled passenger flights did not start again until the 1980s when Arcus-Air Logistic operated flights between Mannheim and Oberpfaffenhofen near Munich, using Dornier 228 aircraft. These flights were offered up to three times daily, depending on demand. Besides cargo flights the airline added three weekly passenger flights to Leipzig and Dresden in 1991. In 1997 Cosmos Air (Arcus-Air Logistic) was founded in Mannheim and started nonstop flights to Berlin Tempelhof Airport and London City Airport using the larger Dornier 328 turboprop. Due to lack of demand, the London route was suspended one year later. Up until that time, a provisional container building had been used as the terminal, but new facilities opened in 1998. In 1999 Cosmos Air was taken over by Cirrus Airlines, continuing the flights to Berlin-Tempelhof and opening new routes to Hamburg and Saarbrücken. With the entry of Cirrus Airlines into Team Lufthansa in 2000, Lufthansa came back to Mannheim after 60 years of absence, and Mannheim reappeared in the official Lufthansa itinerary. In 2002 Mannheim-Neuostheim was officially renamed Mannheim City Airport. In October 2008 Cirrus Airlines started new direct flights from Mannheim to Munich, connecting the city to one of the Lufthansa main hubs. However, this service consisted for only four months. In August 2010, the Mannheim-Hamburg service celebrated its 10th anniversary, but due to hard competition coming from Frankfurt Airport on this route, Cirrus Airlines had to discontinue it on November 26, 2010. On December 22, 2011, Cirrus Airlines decided to also end the last scheduled route to Berlin-Tegel, shortly before filing bankruptcy. Cirrus Technik also operated a maintenance facility for Dornier 328 turboprop aircraft, which moved to Saarbrücken at the end of 2009. Today Due to its problematic geographical location, an extension of the airport has become impossible, preventing modern regional jets, such as the Canadair Regional Jet or the Embraer 145, from operating from MHG. With the introduction of the new JAR-OPS 2 regulation, strict weight restrictions have been imposed, allowing only smaller
