Which were the short-field airports that led to the design of this capability into the aircraft ? Not London City, that didn't exist when the 146 was designed and didn't get used or even thought about for 146 ops until years after opening.
I also seem to remember it was so quiet that it got under some noise limitations in California and allowed unlimited operations unlike anything else, hence the PSA and Air California sales. What happened to these restrictions, why did they become unimportant ?
