Air Astana plane lands safely after emergency over Portugal
QuoteAir Astana flight KC1388 diverted to Beja Airport, Portugal after reportedly suffering control issues after departure from Alverca Air Base, Portugal.
The aircraft had arrived at Lisbon on October 2 and underwent maintenance at the OGMA facilities, located at the Alverca Air Base. KC1388 was the first post-maintenance flight. The aircraft took off at 13:31 hours UTC.
Shortly after departure, about 13:34 UTC, the flight issued a Mayday to the Lisbon Approach controller, stating they had control problems. The flight requested to return to Alverca. About 13:37 UTC the flight requested to climb to FL100, again stating they had "flight control problems". At 13:45 the flight requested vectors towards the sea for a ditching.
The aircraft continued to circle to the northeast of Lisbon while requesting vectors from Lisbon Approach towards the sea.
As the aircraft continued circling in the area, two F-16 Fighting Falcon jets of the Portuguese Air Force were scrambled from the Monte Real Air Base. Ultimately they accompanied the flight to Beja Airport (LPBJ) were a landing was carried out about 15:10 UTC.

Japan Airlines tightens alcohol rules for pilots
QuoteJapanese law does not set limits for alcohol consumption by pilots.

Instead, it is up to airlines to determine alcohol limits for pilots on duty.

Mr Jitsukawa was arrested after he was found to have 189mg of alcohol per 100ml of blood in his system - the legal limit for a pilot in the UK is 20mg.

That's a bit surprising if true - for the jurisdictions I know of, it's set by a regulator/govt at a very low amount to allow for false positives. The rule of thumb for pilots is often given as "8 hours bottle to throttle," meaning that you don't drink in the 8 hours prior to touching an aircraft's controls (but this doesn't always work out).

Why we need the SpaceForce, high-tech laser weapons, high-flying mini-drones swarms, and hacking...in addition to our pilots and land, sea, and undersea operations.

‘There is no god but Allah’: Pilot converts to Islam while flying plane above Saudi Arabia
QuoteA Brazilian pilot is making headlines in the Arab world after he reportedly took a brief break from guiding the plane to convert to Islam as he flew a passenger jet above Saudi Arabia.

Captain Amalo, a Brazilian pilot for an unidentified airline, was filmed reciting the Shahada, an Islamic creed accepting the religion, in tandem with a colleague as they operated the controls of an aircraft.

It all looks the same now.  I guess the days when different answers were arrived at are long gone



An argument can be made that aircraft of a specific generation look similar as a function of the state of advances in technology.....propulsion, aerodynamics, manufacturing, avionics, control systems, low observability, etc.  Consider jets since the end of WWII, all first gen (F-80, Meteor, Ouragan, MiG-9) had straight wings, which gave way to swept wings (F-86, Hunter, Mystere, MiG-15), followed by delta wings/area rule fuselage (F-102, F-106, MiG-21, Mirage), and briefly variable sweep wings (F-111, Mig-23, Tornado, F-14).  Fly-by wire was the next big thing, and then low observability which drive blended surfaces in the current state of the art a/c.

During that time, naval fighters were usually about half a generation behind their land based contemporaries due to the additional mission/operational requirements that had to be accounted for.

Lionair crash initial findings
QuoteOn Nov 22nd 2018 the KNKT gave a presentation to Indonesia's Parliament about the findings so far. The KNKT told the parliament that the FDR contained 1790 parameters spanning 19 flights. The last two flights, the flight from Denpasar to Jakarta as well as the accident flight, were showing the same issue, the right hand speed (first officer's IAS) signficantly higher than the left hand speed (captain's speed). The captain's AoA indicated about 20 degrees higher than the first officer's AoA. As result the left stick shaker activated immediately after takeoff and operated, with a brief period where it stopped during a descent shortly after takeoff, continuosly throughout the flight. When the aircraft levelled off at 5000 feet automatic nose down trim inputs occurred which were countered by manual trim up inputs by the crew. The nose down trim inputs were created by the Maneouvering Characteristics Augmentation System (MCAS), a tool which will lower the nose of the aircraft to prevent a stall. Until the end of the flight the automatic nose down trim inputs were countered by manual nose up trim inputs by the crew. During the end of the recording the automatic nose down trim inputs increased, the pilots still trimmed nose up however shorter. Overall the stabilizer trim position moves increasingly towards nose down until it was no longer possible to counter the pitch down moment via the yoke. Throughout the flight there had been no problems with the engines. On the previous flight from Denpasar to Jakarta the same problem existed, the automatic trim inputs however did not occur. The crew must have done something preventing the MCAS system producing the nose down trim inputs.
https://avherald.com/h?article=4bf90724&opt=0

Just a bit of an explanation for those who don't know: trim is a mechanism which allows the pilot to adjust how much force is being exerted on the controls, typically to reduce it to a point where you can fly 'hands off'. As you can see from above, control forces can be large enough that it's physically impossible for pilots to overpower it without adjusting the trim.

Maybe they were Russians! I hope they scoured the ground nearby for passports.

Merkel plane technical failure prompts return to Germany
QuoteGerman Chancellor Angela Merkel will miss the opening of the G20 summit in Argentina after her plane was forced to land shortly after leaving Berlin. The captain announced to passengers on Thursday evening that he had decided to turn back after the "malfunction of several electronic systems".

The plane's communications system went down and the crew had to use a satellite phone to contact air traffic controllers, Germany's Spiegel website reported. The problem is thought to have been with an electronic distribution box, which controls both the radio and discharge of aviation fuel. The German air force denied suggestions that the plane's electronics could have been sabotaged. "There's is absolutely no indication of a criminal background," a spokesman said.
The Airbus A340-300 hit by technical failure is named Konrad Adenauer after West Germany's first post-war chancellor.

The plane's technical problems are nothing new.
In October finance minister Olaf Scholz was on a trip to Indonesia when the plane was grounded because rodents had gnawed through electrical cables during an annual meeting of the International Monetary Fund (IMF). Last month, President Frank-Walter Steinmeier arrived late for a trip to South Africa because one of the plane's engines would not start.

There's always a lot of talk about how underfunded and badly managed the Luftwaffe is, might be related to that.

B-52 Squadron Commander Fired over Penis Drawings in Bomber Cockpits
QuoteThe former commander of the 69th Bomb Squadron, Lt. Col. Paul Goossen, was removed from his post after penis drawings were discovered on a moving map software inside the B-52’s cockpits. The incident took place during a deployment to Al Udeid Air Force Base, Qatar and came to light after screengrabs of the images were later used for laughs at an end-of-deployment party.

Our Fathers and Grandfathers had more leverage I guess.  "Oh.  So you are saying I can no longer bomb the Third Reich
because there is a girlie pix on my aircraft?   Great.  Find someone else then."

The way I read that article makes me think that they'd drawn penises with waypoints or something on their nav computer in flight, and if that's the case it's not as though anyone would've known about it if not for the pictures afterwards. At least with nose art more people except the immediae crew might've seen it and taken offence.

The Brits had some fairly racy nose art on their aircraft during Desert Storm.  Surprised they got away with it considering they were flying out of Arab air bases in Muslim countries.  I asked a Buccaneer pilot about it, he said they told the locals to fuck off, if they did like it they'd leave and let them deal with Saddam by themselves.

Crawling into the nose like that doesn't look enjoyable:


It sure doesn't.  You definitely want to be in the left seat there.

Better for you to be short too, which I'm not.

The Royal Flying Doctor Service (RFDS) has recently been getting deliveries of the PC24, with the intention that they can be used on unimproved outback strips (like what they use the Kingairs and PC12s for now). Going to be interesting to see how successful they are, since it seemed like Pilatus were designing a lot of the capabilities of the PC24 around the demands of the RFDS and their operations in the outback.

A Southwest 737 overran the runway at Burbank on the 6th December - 18 and a bit years after they did the same thing there.  ::)

I guess it was a good idea to install an engineered materials arrestor system (EMAS) after the first accident as it looks like that's what saved them today. They're normally installed in places where there's not enough space for an overrun area (eg in the middle of cities), and are intended to use some kind of crushable material to quickly stop an aircraft without injuring anyone.

Hey.  That EMAS stuff looks pretty cool.  What a fun gig that would have been in developing that stuff!

Was that a fuel jettison by the Su-34 at about the 0:42 second point of the video?

Looks like it, and other Sukhois seem to dump from the same area.

Reminds me of the F111s doing a party trick where they'd dump fuel and immediately ignite it:

Is that a Su-25 "Frogfoot"?  Looks like a Russian version of the A-10 "Warthog."

My relatively minor research I just did now indicates the Su-25 was built for the same CAS role the A-10 was designed for.  Apparently they even made a "tank-killer" variant of the Su-25.  Neat.
