On the A321neo, the flare law does not include automatic compensation for thrust-related pitching moments. This applies whether it's the nose-down tendency that occurs when thrust is reduced to idle, or the nose-up tendency that can result from selecting TOGA thrust. Below 100 feet radio altitude (when flare mode...

When you're a 100-ton unpowered glider with the aerodynamic profile of a brick, "landing" is really just a high-stakes conversion of kinetic energy into heat and friction. At 320 mph, Atlantis executes its "pre-flare" maneuver; a critical pitch adjustment to bleed off velocity and increase lift. From the deployment of the drag chute to the final nose-gear touchdown, every second is a masterclass in managing the transition from orbital mechanics to subsonic aerodynamics. At the fundamental level, the Shuttle program was a 25-year experiment in defying the laws of drag and gravity to bring humanity home from the vacuum of space. Credit: NASA/Space.com

Why is the CRJ tricky to land? The CRJ’s main landing gear sits behind the center of rotation, making the flare less forgiving—pitch a bit too much and you risk driving the gear onto the runway. On top of that, the struts are quite sensitive and can compress quickly, so if not carefully managed, it can result in a firm landing. 📹: YVRplanes

DC-10 drops 85,000lbs of Phos-Chek retardant over the Wahluke Slope Fire/Saddle Mountains back in September 2018. When the aircraft suddenly releases that much weight, the biggest immediate effect is on trim. As the airplane becomes lighter, it needs less lift to maintain level flight, creating a nose-up pitching tendency. You can actually see the aircraft begin to pitch up the moment the drop starts. Pilots must instantly counter it by pushing the nose down to avoid a stall or even structural damage. 📹: Tonia Hill

All Nippon Airways (ANA) Boeing 767-300 battles strong crosswinds on final approach to Osaka International Airport in 2021. Despite being tossed around by the wind, the pilots smoothly correct the aircraft's attitude before touchdown, followed by a firm landing. Then the reversers kick in. This is when reverse thrust is most effective: on a wet runway. Impressive display of airmanship. 📹: AirlinersFreak

Luxon butchering Te Reo before he launches into one of his woke progressive speeches is like hearing the pop and hiss of cracking open a can of Bud Light. Cam Slater has written today that the Nats are helicoptering in Paula Bennet to stab him from the front while his MP’s pat him on the back - in order to feel where to stick their knives. Luxon’s pathetic political career is coming to an end, so how about a retrospective ? “Chris Luxon this is your life !” Everyone with half a brain knew what he was going to be like. Did those who voted for him watch his maiden speech? Here it is if you missed it May 24th 2021. It’s truly a speech that perhaps only Ardern herself would be so cynical to deliver with a straight face. Here’s the break down of the 4 minute speech. * Tay Rayo introduction * Diversity pitch * Immigration pitch * Diversity pitch * Climate change pitch * Globalism pitch * Air NZ career pitch * Globalism Pitch * Diversity pitch * Critical race theory pitch * Gender ideology pitch * Diversity pitch * Rainbow tick pitch * Getting things done pitch * Getting things done pitch * Diversity pitch * Getting diversity done pitch * voters will get what they deserve pitch So who remembers this speech? And yes it was THIS BAD, no joke. Maybe everyone who voted National was just so keen to dump Labour they fooled themselves that Luxon was the panacea? Also Trump rising from the ashes has put the spot light on a diminutive man with an even smaller appreciation of what the average sane kiwi wants. They can change him out, for a cosmetic attempt at pivoting but that party will never change - at the core of its fundamental philosophy is - woke nothingisim.

The 10-15 seconds in between pitches are the most important time of a baseball game. All ballplayers should be looking to win this time. The best way to do that is having a set pre-pitch routine that they execute every pitch. A pre-pitch routine is simply what players do on a consistent basis in-between pitches. Most importantly, it’s how they breathe, focus, visualize, and talk to themselves. This is what helps them take control, keep it simple, and compete with all they’ve got ONE pitch at a time.

This is an Erickson Aero Tanker MD-87 flying with the landing gear down while fighting a wildfire. It may look unusual, but there is a reason for it. The extended landing gear creates significant drag, meaning the pilots need to maintain a higher power setting. That is important because the MD-87's engines can have a relatively long spool-up time when operating at low thrust fighting wildfires. If more power is suddenly needed, waiting for the engines to accelerate can cost valuable seconds. By keeping the engines at a higher power setting while using the landing gear to create additional drag, the aircraft remains closer to its maximum available thrust. This can significantly reduce the time needed to reach full power. A well-known technique when rapid power changes matter. Also, the way the second chase aircraft is following so closely is incredible to watch. 📹: Even_Kiwi_1166

Instagram censors Airbus. I was editing this video of a low visibility Auto-Land in an Airbus A330, although when I selected Captions to highlight the auto-generated calls and the pilot responses, the App automatically censored the “Retard” calls. This is a classic case of AI misunderstanding technical language. On Airbus aircraft, the “retard” call is a completely standard, safety-critical prompt that has been used since the A320’s introduction in 1987. It’s an automated audio call triggered at a specific altitude—20 feet above the runway during a manual landing, or 10 feet during an autoland—to remind pilots to pull the thrust levers back to idle for a smooth touchdown. Anyway, when landing in fog, we engage both autopilots and monitor the aircraft flying an autoland. The minimum forward visibility allowed to land is 75 meters because that’s the minimum we need to be able to taxi onto stand. At airports that we’re not familiar with, we can ask for “Follow-Me” vehicles with flashing lights to guide us to our parking stand. 📸 by ig/captainchris Not an ad

This young man on the mound, a senior in high school, started the game and threw one pitch in the game on senior day. The back story is that he was injured by a line drive in March ending his career with a brain bleed. The young man up to bat is a senior and the son of the mom who filmed this. He agreed to not swing at the pitch. They said there wasn't a dry eye in the ballpark. This game is so much greater than that little white ball! In a world of such chaos and hate, I love, love, love this so much.❤️ How can you not be romantic about baseball?

The MD-11 has always had a critical design flaw. It was manageable until someone screwed up. To improve fuel efficiency and range, its horizontal stabilizer was made smaller than those of earlier DC-10 variants. While the design delivered performance benefits, it also reduced the aircraft's natural pitch stability, particularly at slower speeds during approach and landing. To help compensate, the MD-11 relied heavily on computerized stability augmentation systems. Many crews also preferred flying slightly faster approaches, which improved pitch stability but could make the aircraft more challenging to manage during touchdown due to its weight and sensitivity in roll and yaw. These characteristics became evident in several high-profile accidents. In 1997, a FedEx MD-11 arriving at Newark was reportedly operating under the belief that runway length was limited, prompting the crew to aim for an immediate touchdown. The aircraft landed hard, bounced, and became unstable. Instead of executing a go-around, attempts to salvage the landing resulted in another severe impact, collapsing the landing gear and destroying the aircraft in a post-crash fire. All five crew members survived. The accident highlighted a key lesson: when an MD-11 bounced significantly after touchdown, a go-around was often the safest option. That lesson resurfaced in tragic fashion in 2009 at Narita, Japan. During strong and gusty crosswinds, a FedEx MD-11 touched down hard and bounced. Believing the aircraft could still be recovered onto the runway, the crew attempted to continue the landing. The resulting control inputs led to an even harder impact, loss of control, and a crash that destroyed the aircraft and claimed the lives of both pilots. 📹: buybygb

🚨People watching this think it looks fake… It isn’t. That is a real F-22 Raptor performing an unrestricted climb. This maneuver is something only a handful of aircraft on Earth can do. When the pilot rotates and goes straight up like that, the aircraft is converting pure engine thrust into vertical climb. The reason it can do it comes down to the engines. The F-22 is powered by two Pratt & Whitney F119-PW-100 turbofan engines. Each engine produces about 35,000 pounds of thrust with afterburner. Combined thrust: About 70,000 pounds. Now compare that to the aircraft’s weight. Typical combat weight: ≈ 64,000 pounds That means the Raptor has a thrust-to-weight ratio greater than 1:1. In simple terms… The engines produce more thrust than the aircraft weighs. That allows the jet to accelerate vertically. And it gets even crazier. The engines use two-dimensional thrust-vectoring nozzles, allowing the exhaust to tilt up and down to maintain control even when airflow over the wings is minimal. Top speed ≈ Mach 2.25 (about 1,700 mph) Supercruise ≈ Mach 1.5 without afterburners Service ceiling ≈ 65,000 feet Only about 183 operational F-22s were ever built. Which means when you see a Raptor do this climb… You’re watching one of the most advanced air-dominance fighters ever created. #SilentMajoritySpeaks #AStoneGroove

Big league vs. college bullpens.📝 A common theme in amateur bullpens is a lower standard of what constitutes a "good" pitch. Big leaguers tend to be much more self-critical regarding location, even in velo or pitch design pens. "How hard can I throw it, or can I create this shape while still being reasonably around my spot." You may not have big league stuff, but adjusting the standard for what constitutes a successful pitch is something amateur pitchers do have full control over.

ELON: I’M STILL AMAZED THAT WE BUILT STARSHIP “I'm still amazed that Starship actually got put together and took off. Starship is more than twice the thrust of a Saturn V. It is by far the biggest flying object ever made. And with some upgrades down the road, it'll actually be probably over 20 million pounds of thrust. And Saturn V is 7.5 million pounds of thrust. So it'll end up being three times the thrust of Saturn V. And it's going to fly a lot. It has to fly a lot. It's going to end up flying several times a day from many different locations in the world. And I think there's a pretty good chance that it does Earth-to-Earth transport as well, because the fastest way to get from one place to another on Earth, to get from here to the other side of Earth, is an intercontinental ballistic missile, but just make sure you delete the nuke and add the landing part. Basically, that's the fastest way to get somewhere.” Source: SpaceX All Hands Meeting, January 2024

🚨WHOA!!! Gravity Just Got Outmatched… Watch a C-17 Drop Out of the Sky Using Reverse Thrust Most people think giant cargo aircraft descend slowly in wide lazy circles. Not the American 🇺🇸 C-17. What you’re seeing in this footage is one of the most aggressive controlled descents ever engineered into a military aircraft. The C-17 Globemaster can actually deploy thrust reversers while still in the air… something almost no other jet transport can safely do. When those massive engines flip into reverse thrust, the physics of the aircraft changes instantly. Instead of the engines pushing the aircraft forward… they begin fighting the forward motion of the airplane. The result is dramatic. The aircraft can transition from flying nearly parallel to the horizon… to a steep nose-down descent that looks almost perpendicular compared to the Earth below. Pilots can drop altitude incredibly fast… going from high cruising altitude to landing approach in just a couple minutes. Why does this matter? Because the C-17 was built for battlefield logistics. It was designed to fly into dangerous airspace, descend rapidly to avoid threats, land on short or rough runways, unload equipment or troops, and get back into the air before anyone has time to react. That rapid descent capability allows the aircraft to minimize time exposed to enemy radar or missile threats. The moment the thrust reversers are disengaged, the aircraft stabilizes instantly and transitions back into normal controlled flight for landing. It’s a perfect example of American aerospace engineering. Four massive turbofan engines… flight computers… and aerodynamics working together to make a 585,000-pound aircraft move like a precision instrument in the sky. For people who have never seen reverse thrust used mid-air before… this footage is a rare look at how military airlift aircraft operate when seconds matter. It’s one of the coolest demonstrations of aviation physics you’ll ever see. #SilentMajoritySpeaks #AStoneGroove

The Engine Start Levers or Fuel Cut off switches (different name, same switches) control the fuel and ignition for the engines. The 787 shares the same switches and very similar logic to the Boeing 737 Max. The switches have been designed in such a way that they require a very deliberate movement in order for them to move from one position to another. They’re also placed in such a position (below the thrust levers) so that it’s very unlikely that they’ll be knocked. But even if they were, the spring force and detent would prevent them from moving unintentionally. When we move the start levers from the “Run” or “Idle” position, to “Cutoff”, an electrical signal is sent to move the fuel valves from open to close. The engine ignitors are also then de-powered. This stops the supply and ignition of fuel and the engine spools down. Pilots are trained from day one to only touch those switches in flight when called for by a non normal checklist, such as an engine fire or failure. When a fuel switch has to be moved to cutoff in flight, we adhere to a very strict procedure… Pilot monitoring will place their hand on the switch of the damaged engine and both visually and audibly confirm with Pilot flying that the correct fuel switch has been selected. Only after both pilots have confirmed that the correct switch has been selected, will pilot monitoring move that switch to the cutoff position. As an additional layer of safety, some aircraft types only allow the switch to be moved to cutoff in flight if the thrust levers are in the closed or idle position. Do you think that this design feature should be implemented in all aircraft? 📸 by ig/airlinepilotperformance
