More Airports to Use Greener ‘Glide’ Approach to Landing -"(by having incoming planes turn off their engines"
https://www.scientificamerican.com ^ | February 1, 2023 | By Minho Kim, E&E News on

Eleven more U.S. airports plan to adopt a new way of landing planes that reduces both emissions and noise — all by having incoming planes turn off their engines and glide down to the tarmac like a paraglider.

The Federal Aviation Administration announced Monday that planes heading to Orlando, Fla.; Kansas City, Mo.; Omaha, Neb.; Nebraska's Offutt Air Force Base; Reno, Nev.; and six airports in South Florida soon would make idle descents to runways. It's a method called “Optimized Profile Descent,” and more than 60 U.S. airports already have it in place.

I thought that this what they referred to as Dead Stick Landing. Well maybe not totally Dead, those Lithium Batteries will get a hell of a workout till they burn out.

Sorta kinda makes me even happier, I swore off flying when I retired. It will be interesting to see what happen during a
storm if any kind when those “incoming planes turn off their engines and glide down to the tarmac like a paraglider.”
I wish them luck.

uh, stupid question, as you hit the tarmac doing 200 or so how do you slow down if your engines are off? aren’t the engines put in reverse to effect this?

Well, what can go wrong?

It’s all fun and green games until the bodies get stacked up.

Sounds unsafe, what happens if they have to abort because of an incursion?

Scientific American is not the Scientific American I read when I was a kid.

Nobody will be shutting their engines off while landing. This is just dumb.

The reactions from the Airline Pilots union and passenger groups ought to be interesting.

The approach does NOT involve turning off the engines. It involves setting them to idle. They’re still running and can be powered up if necessary. To make the car analogy - think of your car in idle versus the engine being off.

Interesting. “Going Missed” and the subsequent “Go Around” will be exciting. Especially with all the new Affirmative Action pilot hires at the controls. America dies a little more with each passing day.

"Scientific American" sure has morons for writers. No pilot ever would "turn off the engine and glide to the tarmac".

Optimum Profile Descents have been around for decades. It is simply an arrival procedure from ALTITUDE that does not have multiple intermediate level off altitudes. This permits an idle descent from high altitude. The final descent altitude is usually around 10,000 feet above the airport elevation - and from there the engines are definitely spooled up (certainly NOT turned off) as the aircraft is configured to land.

“A hospital! What is it?”
“It’s a big building where we’ll be taking these passengers after we crash, but that’s not important right now.”

After this is well-accepted, next up is Idle Takeoffs!

"because of safety concerns..."

I'm very sceptical. The first time all passengers onboard perish in a fiery explosion the Biden admin will blame it on Trump or pilot error. See how our government treats citizens as expendable loss in the pursuit of the climate change religion? Sacrificial lambs.

I was a Delta flight attendant for years. I imagine many airline personel will retire early.

Well no more flying for me. Even at idle it means less control. My guess most good pilots will ignore the hell out of such a practice.

I propose building an elevated runway that will vary it’s gradient thus allowing a plane to just fly in through a window and be slowed to a stop without braking or reverse thrusting.
A high speed elevator would transport passengers up from the ground. Departures would be on the down gradient of the landing planes on parallel runways.
With the built in elevation they would just glide right out on their way without the need for takeoff power and would utilize solar powered engines to maintain their cruising speed onward to their destination.
It will be the next generation of green travel.
