Hi Thowe,
If you want to focus on something now, I would target the tower frequency. Especially if you are close to the airport and receive the aircraft on the ground well.

Unfortunately I'm not close enough to the airport to cover tower frequency.

Together with two other enthusiasts we are preparing a huge offer for LSGG. From Radar Upper Level to Tower and Ground everything should be available in very good quality at the end. A part of it might go online soon.
OK : My coverage of 136.255 is not a "top quality" reception, especially when the weather is bad. When available, your coverage will be more complete, and certainly with best quality. LiveATC suhould publish the best quality, I agree  :-D.

Thanks for the info.

You can only stream two frequencies separately with one dongle if they are within a 2.5MHz window. Otherwise you have to configure a frequency scanning mode where you only hear one frequency out of many. Details can be found in the RTLSDR Airband Wiki.

Aviation News (General) / How did Delta Airlines awaken 570 dormant aircraft?
« Last post by KB4TEZ on October 08, 2021, 12:45:44 PM »
Really interesting read.

https://www.freightwaves.com/news/how-did-delta-airlines-awaken-570-dormant-aircraft

AskWaves describes the technical work behind parking, storing and reactivating aircraft during a pandemic. Delta Air Lines parked 571 mainline aircraft across the country in 2020 when the COVID-19 wiped out most passenger travel. Airlines still have about 70% of their pre-pandemic international capacity in hibernation, but Delta is returning aircraft to the skies because the U.S. domestic market is recovering faster than in other parts of the world.

Parking a plane and bringing it back to life after months of inactivity isn’t as simple as turning the engines off and on. It takes a lot of effort, including maintenance and electrical checks, to keep an aircraft in a ready state for future use.

As the pandemic reached the U.S. in March 2020, Delta (NYSE: DAL) began parking aircraft in Blytheville, Arkansas; Kansas City, Missouri; Marana, Arizona; and Birmingham, Alabama. Each location had separate challenges, such as humidity, desert heat or bugs and small animals nesting in crevices.

In some regions of the world, for example, mud dauber wasps clog exterior speed-sensing tubes with mud. Maintenance personnel are instructed to regularly check the probe covers for damage.

So many aircraft were flown into the Birmingham airport that Delta technical teams ran out of the chocks placed by the wheels to hold the aircraft in place. Workers bought 6-by-6 skids of wood from local hardware stores to hand-make replacements, the airline said in a recent blog post.

Finding airports and fields that had room for aircraft was a big undertaking itself. In San Bernardino, California, a designated parking area wasn’t usable after a  Boeing 757 began sinking into the pavement. And runways in Kansas City and Victorville, California, were only temporary, so the planes eventually had to be moved again. Planes in long-term storage also need special covers placed over the engines and fuel to be removed if they are kept in a hangar.

Delta TechOps scheduled maintenance work for each aircraft at seven, 14, 30, 60, 100 and 180-day intervals. Coordinating the checks and spreading out the work required extensive planning, according to the airline. The engineers developed flexible “job cards” for each aircraft specially tailored to the climate conditions where they were parked, while conserving supplies and manpower.

“Putting an aircraft to sleep really hasn’t been done in the Delta world before. Some of the tasks have never been written for a lot of these airplanes because they were fairly new,” a maintenance program manager in Atlanta said in a Delta video.

The pandemic complicated the storage efforts. Most mechanics commuted to different storage facilities for periods lasting a few days to a month and couldn’t eat at restaurants because they were closed. At one location, a chief used the hotel kitchen to make meals for his team.

Many stored planes were stripped of certain parts to help repair planes in service. When it was time to reactivate them, mechanics had to find and reinstall new parts.

All planes reentering service have their systems activated and reviewed, and gears and components greased. Then they undergo a test flight before going to a repair facility for a maintenance overhaul, according to Delta’s blog. Smaller planes can take about 10 days to two weeks to rehabilitate. Larger aircraft can take two to three weeks to fix up. The process is longer for planes stored 180 days or more, especially if there are expiring components that need replacement.

When the maintenance is finished, pilots arrive to fly the plane to an airport where it will pick up passengers and cargo.

So far, Delta has returned 493 aircraft to the active fleet. The company expects to be reactivating aircraft into 2022.

There are no messages from you in our support system. Please PM me offline with a ticket number if you have one. But checking your email address there is no contact.

18 months after, I'm back  :wink:

I've done a successful rtl-airband config. I can now provide :

LSGG Geneva Arrival: 136.255
OR
LSGG Geneva Departure 119.525 (or 119.530 ?)

I don't know how to provide 2 freqs with only one dongle.

I will fill the ad hoc contact form and DM to Dave.

Aviation Accidents/Incidents / Incredible Video Of Plane Crash On Texas Highway

(wow video !!!)

A Texas pilot is lucky to be alive after his plane clipped a streetlight, sending the aircraft crashing onto the highway below.

According to reports, the incredible video was taken on Saturday in Winnie, Texas. The plane took off from Highway 124, clipped a streetlight, and sent the vessel to the ground.

Local reports say the plane had been used in a parade as a float. So the pilot decided he would take off from the street to return home.

Luckily, the pilot was not injured in the crash. However, the street was closed for several hours.

The cause of the crash is currently being investigated, but it is believed windy conditions may have contributed to the pilot losing control.

(thank you AVH)
cool under pressure crew for sure.

A Spirit Airlines Airbus A320-200N, registration N922NK performing flight NK-3044 from Atlantic City,NJ to Fort Lauderdale,FL (USA), was accelerating for takeoff from Atlantic City's runway 31 when the crew rejected takeoff at low speed (about 60 knots over ground) advising they had a bird strike into the right hand engine (PW1127G) and were stopping on the runway. The aircraft slowed safely and stopped on the runway about 550 meters/1800 feet down the runway, tower queried whether the aircraft needed any assistance, the crew replied "roll the trucks please". A short while later tower advised there appeared to be fire underneath the engine. The crew acknowledged, the fire bell was audible in the background of that transmission, and about a minute later advised they were evacuating the aircraft. There were no injuries.

The airline reported a large bird entered one of the engines, the crew braked safely and brought the aircraft to stop, received indication of engine damage and ordered an evacuation in line with standard operating procedures.

Videos show the aircraft was evacuated through the left hand forward and left hand aft main doors using slides.

On Oct 4th 2021 it emerged, that an entire fan blade had fractured at its root and separated.
