Perhaps this is why those of us who live east of LAX now have hundreds of planes flying over our houses every day at much lower elevations??? Quieter for residents near the airport, but a nightmare for the rest of us.

It depends where you live exactly, but landing speeds are probably around 130 to 150 kts. Of course, that’s airspeed so if there’s a strong wind blowing, ground speed can be lower.

what are the speeds of thes planes when they fly over my house in southeast LA i watch them all the time and wonder how fast they are going,the bigger one 747 and the like look like they are just flootting thank you in advance sean

[...] that can be replaced by a gentle glide – allowing the use of minimal throttle. These CDAs (Continuous Descent Approaches) are being trialed at the UPS main hub in Louisville, Kentucky and are reckoned to save 40-70 [...]

Very well written.This is great news.Decreasing emissions/fuel burn and noise in one shot.

@ Sheila what is slam dunk approach?

CDA is re-inventing the wheel. It demonstrates how easily a new generation forgets or has ignored what came before. Airlines always conducted such approaches wherever and whenever they could. Just what does “establishing a CDA mean? It’s up to the pilot to chose what method of approach to use not an airport. All sorts of conditions impact the use of CDA that the pilot has to deal with. If an aiport imposes a CDA and aircraft arrive at a greater rate than what can be sequenced into a CDA it simply means that they burn more fuel orbiting in a holding pattern.until it’s their turn. Nothing is saved.

[...] That press release also mentioned that Air New Zealand has been participating in a special progam in San Francisco. Lo and behold, I just completely missed the press release. The airline is testing out a special kind of approach there. Basically, instead of the typical approach that is full of descending and leveling off, the aircraft starts descending at a gradual pace far away from the airport, without ATC directing them too much. I’m not sure if this is the same thing, but it seems quite similar to a program at LAX that Cranky describes [...]

The LAX CDA is almost worthless due to spacing requirements.. I watch the LA final on my radar at work, and at least 50 percent of them are vectored back-and-forth across the final to increase the spacing necessary to feed in aircraft approaching LA from the north. It’s funny to see the FAA (Gregor) tout the CDA, and watch it screwed up in practice. Nobody is saving fuel or money. Take that to the bank…

The Continuous Descent Arrival has proven to be highly advantageous over conventional dive-and-drive arrival and approach procedures.
From the environmental perspective, there are significant reductions in noise and emissions . From the economic viewpoint, there are significant fuel and flight time savings as well as the potential to meet or exceed current runway throughput without the need to vector aircraft.

I also heard that Delta was testing CDAs at ATL.
