    In Todays episode I will dig deep into Aircraft energy states, unstabilized approaches and why they happen. We will talk about descent planning, dangerous shortcuts as well as how pilots can loose hearing if they get too far down the "stress cone".
    I will also, towards the end of the video, discuss a case study where an unstabilized approach led to a real crash so stay tuned to the end!

As PM I would not want to take control, if the PF would not go around I wonder how smooth the transfer of controls would be, especially since I am an FO. Best thing to do if the PF will not go around , call the tower or approach and let them know you are going around.

I have been on a flight where the pilot was trying to land; we all noticed on the monitors in front of our seats that he was still going the equivalent of 300mph, which seemed high. Right before we were about to hit the runway, he ascended, and then we circled the airport for ten minutes before he got on the PA and said that "it was too windy to land". Judging from the earlier moderate flight turbulence we experienced a few hours earlier in the flight and him not saying anything, I assumed he was a new pilot.

Question on exiting a hold to return to the missed approach runway what is the best procedures to accomplish this? Using the FMC and map and vectoring??? I understand that the aircraft will not automatically go the the missed approach runway, but the pilot has to work with the FMC and map and vector the aircraft as it will not automatically vector itself to the runway? Any advise would be appreciated.

I don’t want to appear nitpicky, but energy cannot be created or destroyed, you don’t destroy it by creating drag, you transfer it to the air around you as mostly kinetic energy, as I understand it at least.

Energy can not be created nor be destroyed, it can only be changed from one state to another( First Law of Thermodynamics). The raising the speed brakes you are just dissipating the energy from A/C to the surrounding in the for of heat or turbulence(kinetic energy of air around you).

Hi great video I love your info that you provide. I do have a question for ya though. I was coming in for a landing... the pilot was probably on a final because the flaps were all the way extended. However the situation or at least how I felt it was that the airplane was at a 10degree nose down the spoilers were out and it felt/sounded like he had it in reverse thrust. I know it was probably in my mind but it felt like we were just hanging in the sky. Could you explain this? (he probably didn't have reverse thrust on but it sure felt like it.) Also the pilot made a very hard landing I thought the gear was going to fall off. lol

You probably didn't mean it like this but just a physical point - drag isn't destroying any energy, it's transferring it to the atmosphere (which I assume is what you meant, that you are ridding it from the aircraft).

Airbus 320 sop allows speedbrakes in config 3 (equivalent of flaps 20 kind of). The buffet margin is quite tight but it’s unlike Boeing 787 sop where speedbrakes past flaps 5 is specifically told to be avoided. Difference in philosophy? difference in actual structure and aerodynamics? I wonder. Maybe I’m just remembering wrong and airbus didn’t recommend it either.

Well the energy is not destroyed here by drag either. It's just converted to heat dissipitated to the air. The only way to destroy energy is nuclear reaction, but that involves Einstein's relativity and quantum physics so whatever. The lift generated by the wing is proportional to air speed (technically velocity squared) and angle of attack. So when the speed is reduced, the lift is reduced. When the lift is lower than the weight of the aircraft, you're descending.

This reminds me on the tragic crash of Airfrance flight 296 Airbus A320 in 1987 at Mülhausen-Habsheim. There was a kind of an airshow. I have read that the pilots were adviced to make a fly over at 100 feet! It was said that the pilots even had no data of this small airfield in their flight managemant computer. Do you know, what happened exactly, that two experienced pilots end up in this disaster?

My scary story Last year I was on a Ryanair flight from Porto to London Stansted, on landing the plane was tilting left to right very aggressively. I looked around and people seemed to be worried, but for me, since I love aviation and flown a lot of hours in the simulator, I felt very calm. The only thing in my head was: "Oh nice, I was never in a flight where the pilot needed to abort the landing" "These people are worrying for no reason the pilot will abort the landing for sure" I even told the lady next to me: "Don't worry, the pilot will abort the landing and try again, I'm a frequent flyer don't be scared, this is normal, everything is ok" I was expecting to feel the engines pushing me back against my seat at any moment. *Few seconds go by...* Ok any moment now... *Few seconds go by...* Wait.... is the pilot crazy enough to land like this!?!?!??! WTF *Few seconds go by....* POOOOWWWMWMM POOOWM I was on a window seat, the left-wing came centimeters from the grass, I'm not joking. The bang was the loudest bang I have heard, everyone started screaming, my face almost hit the seat in front of me, that's how hard the landing was. The plane landed left wheel first, followed by the front wheel then the right wheel, I know this because the G forces pushed my body to the left, then to the front (almost hit my face in the seat ahead of me) than I was pushed right. To this day I have no idea how the wing didn't hit the ground, and how the landing gear was able to survive that impact. I know they are VERY strong but still, the bang was loud af. 2nd Story: Landing in Krakow with Ryanair, now this was my 3rd flight and my first international flight, a few minutes before landing the plane started turning left and right up and down very hard, I felt like I was in a rollercoaster, I was enjoying that a lot I thought it was normal. When the plane stabilized I was thinking OH Nice! flying is awesome, let's do that again! Then the caption started to speak. "Ladies and gentlemen here's your captain speaking, don't worry, everything is ok now, she's ok.... she's ok [refering to the plane]" I was like wait.... was that not supposed to happen? It was fun tho.

As a kid I remember landing in Goose Bay Labrador in a Super DC-8 (stretched) on a refueling stop coming from Europe. The DC8 had no wing spoilers. Some engineering genius realized that if the engines could go into reverse in flight the Douglas would not need to add wind spoilers. It worked perfectly. The inboard engines could go into reverse in flight. There was the tiny problem that the passengers thought the plane was coming apart. The captain had to announce it to keep people calm.

Good video on that topic. Even for smaller airplanes. Just recently I could experience the difference between stabilized and unstabilized approach and the resulting landing. Flying a C152 came in to an airfield, too high too fast. I realized it when I caught myself pushing for the runway threshold. Decided for a goaround, second time went like a charm. A few weeks later came in to another airfield, got into the same situation, but for some reason - maybe feeling overconfident, maybe just simply getthereytis - I decided to push on, to force her down. There was nothing stabilized anymore - I can definitely confirm that stress level is really spiking all the way down. Not helping at all. The airplane felt “uncooperative”. Of course, I was trying to make her do things that did not fit her energy state! Touchdown was barely controlled and just lucky that type of aircraft can take so much. After that I realized that this was a real life “what if” experience. Two high energy approaches, one aborted and the other showed me “what would it had looked like if” I hadn't aborted.

Evidently we came in hot and way too high, I remember the Pilot banking the plane really hard right continuously for about 30 min. just before landing. I thought he was just having a good time trying to see if we all get sick or something. We sat on the left and to the right you were looking out the windows at the ground. Kind of made me mad....

Interesting video. But why not include another option: increase your speed. This increases drag, you want to go as far as possible from your 'best glide speed'. I know this might not be the best idea at lower altitudes, since you also need to get rid of the speed. In my experience on the 737, speedbrakes are only reasonably effective at higher speeds.
