Der "Jumbolino", Avro RJ usw... wurde von den Lotsen "Eisenschwein" genannt weil das Ding nicht stieg. Dann war da noch irgendein gruseliges Geräusch mit den Flaps (oder Speedbrakes?) - gar nicht "Whisperjet" like, und ein Haufen Totalverluste, leider. Ob 2 oder 4 Engines, das hätte wsl nicht den großen Unterschied gemacht. Mit 2/4 wärs vermutlich abwärts gegangen.

Wikipedia sagt zur BA146:

The chosen configuration had a high wing and a T-tail to give good short-field performance, while the aircraft was to be powered by four 6,500 lbf thrust Avco Lycoming ALF 502H turbofan engines. There were several reasons why a twin engine configuration was not chosen, this being a controversial decision for a relatively small aircraft and dictated by the choice of engine which, despite its "rugged, quiet and fuel efficient" characteristics, needed to be deployed in a four-engine configuration to provide the power and range required by the concept. Such a configuration was considered by British Aerospace to be advantageous in the event of a single engine failure, offering "exceptional three-engine performance" that would appeal to operators in mountainous environments and from "high, hot or poor grade airfields".

Ich bin mal in einer von Lugano nach München geflogen und fand den Takeoff auf der kurzen Bahn (ca. 1200 m) eindrucksvoll.
