Brian H Brian the 2km distance isn’t a typical ‘standard’, coincident apart from your event. The atmospheric properties, as well as the frequency band the noise is in are some of the big variants. Again we used to see complaints about a particular pitch of a noise event, that hadn’t caused disruption/annoyance in other localities. I used to have some very detailed academic work regarding noise propagation , most effective in fact for curing insomnia.. 1 Link to post Share on other sites More sharing options...

The engine noise was 'bouncing' due to atmospherics, missing the locals, and landing 2km away. Wind direction and cloudbase height plays a part too in channelling the sound; a few years ago we sat on our deck listening to The Killers ten miles away clear enough to sing along to Mr Brightside (it's compulsory). Of course we were singing 45+secs behind them. Just to say on topic here's a gratuitous pic of a Chipmunk heading downwards from some years back. 8 Link to post Share on other sites More sharing options...

burgundy Posted May 23, 2019 Share Posted May 23, 2019 I had thought that rear mounted engines had gone out of fashion for passenger jets. However, these two photos were taken at Bucharest airport this week. Wiki suggests that there is a pair of ROMBAC 1-11s "in store" at Bucharest and this may be them. The photo needed a bit of zoom - hence the haze - as they were standing with some Romanian Air Force transports on the far side of the runway. Can anyone suggest what else they might be? Then after we had boarded, this was visible a couple of gates along. The tail number indicates that this is an IL-62M freighter, built in 1985, belonging to the Belorusian company, Rada AIrlines.

Jeff Smith Posted May 23, 2019 Share Posted May 23, 2019 There are still Bombardier (Canadair) and Embraer 40 to 90 seat rear-engined commuter jets in service. Rear engine configurations have certainly fallen out of favour for airliners but still the only configuration for business jets, ie, Gulfream, Bombardier, Cessna, etc. 1 1 Link to post Share on other sites More sharing options...

Jeff Smith Posted May 23, 2019 Share Posted May 23, 2019 (edited) Yes, forgot about those, and of course the MD90, most of the less than 100 produced have been bought up by Delta! The Boeing 717 (initially called the MD95) was sold/leased to ValuJet/AirTran. When Southwest bought them, they were all (91) transferred to Delta as Southwest is an all B737 airline. Both types were DC9/MD80 derivatives. There were 158 B717s built, some of which are operated by QuantasLink.

Jeff Smith Posted June 4, 2019 Share Posted June 4, 2019 There have been a few initiatives over the years to re-engine the B52 fleet with modern more efficient turbofans. The first I heard of was to use four RR RB211s on a lease basis. The most recent was to use eight biz-jet sized engines in the existing nacelles - presumably easier to certify assuming the same weight as the existing ones. The quoted increase in range and reduced maintenance you would have thought would make it a no brainer....but! Link to post Share on other sites More sharing options...

There are approximately 17 B717’s operating in Europe, with Spanish/Italian airline, Volatea. A couple of years ago, Volatea regularly operated the B717 into Southampton airport a few times a week during the summer months (May to Oct), flying to Palma and Ibiza. This lasted for a couple of years, but they’ve since pulled out. Very useful for our “lads” trips to Ma-jork-ka.

John I think that went separately in a C-5A Galaxy from Mildenhall. Transport from Portsmouth to Southampton airport was by the Presidential flight helicopters, complete with two Chinooks, carrying security forces. The helicopter formation flew over just in front of our house. Made a lovely loud din. The USAF C-32A (a.k.a. B757-200) took him from Southampton to Shannon to meet the Irish Tea Shop. The press report, that after the talks, he then went on to stay at his Irish golf course retreat before meeting some of the locals. Apparently when his aids told him it was arranged for him to meet the village people, the President assumed Leo had brought along some pals. 2 3 Link to post Share on other sites More sharing options...
