    Dear friends and followers, in today´s video I´ll be explaining, why pilots say "Heavy" at the end of their callsign.
    I´m sure many of you have listened to LIVE ATC conversations here on youtube, and ever so often you can hear the controller and the pilot communicate with each other and the pilot always ends by saying his callsign and "Heavy" at the end.
    The "Heavy" is related to the ICAO wake turbulence categories. As all flying objects create turbulent air in their path, airplanes create so-called wake turbulence. And the heavier and the greater the angle of attack is the stronger the wake turbulence become. Therefore it´s absolutely vital that airplanes keep a safe distance to each other so to not enter the turbulence of the preceding plane.
    Cause of that matter the ICAO came up with a wake turbulence weight category chart.
    But see more about the minimum separations etc. in the video :)

    Thanks for watching, all the best your "Captain" Joe

Very cool. I just thought that "heavy" meant a large, fully loaded aircraft. We live close to an airport, so there are 7-6-7's and 7-5-7's (cargo) flying over quite often. Where we live is quite quiet. So much so, that you can hear the wake turbulence wooshing around above you after the plane has passed. Really cool sound!

@747-pilot Well, as an engineer, you can have a tremendous advantage becoming a better pilot, but only if you study aerodynamics, engines, airframes and aviation in-depth. Having a THROROUGH and FULL understanding can be the difference in being in full command on an extraordinary situation, or just becoming another helpless passenger... Most recently graduated pilots become mere button-pushers, that rely too much on automation, a sure way to crash someday... But a truly knowledgeable pilot that understands how the plane works, will be in a position to solve difficult failures much better. Take the Alaska Airlines MD crash for example: Would those pilots knew about the possibility of MECHANICAL FAILURE, they would had walked back to the rear of the aircraft, and asked if someone had heard any extraneous noise (the noise made by the stabilizer jackscrew stripping its threads). Instead, they kept trying to handle it incorrectly as an electrical trouble (in fact, sadly, they ended up completely stripping the threads with their attempts to force the jackscrew to turn, precipitating the nosedive and crashing). Knowledge always helps, Ignorance kills!

I remember the first time experiencing the wake of aircraft.  I recently moved to a house next to Detroit Metropolitan Airport that was nearly in line with the runway.  I would go out jogging in the evening and on a perfectly calm evening I would hear a rush of wind go through the tree tops every few minutes.  After a while it dawned on me as to what was causing the rush of wind.  Sometimes on humid days the vortices in off of the wing tips would create cloud tubes that would nearly fall to the ground.

Just found your channel after watching your great interview with Kennedy Steve. I was once on Alaska Airlines flying from Portland into LAX, and the plane rolled from side to side approx 30-40 degrees. Everyone was quiet during and after, and I said to my coworker I think we just hit another jet's wake. Prior to that we hit an air pocket while over the ocean and dropped suddenly. The surprise of it made me scream out. The captain never came on the speaker or said anything to the passengers about any of this. Guess he was too busy at the time. Is this proper protocol to not explain anything to the passengers?

Absolutely fascinating video, Captain! I have wondered about the "heavy" designation for a long time. I thought it had to do with the amount of fuel onboard (take off vs landing), but now I know it has to do with the overall weight of the equipment. Does the consumption of fuel after a long haul ever change the designation from heavy to medium or super to heavy? Thank you so much for all your informative videos. Sorry your boss at Air Berlin was jealous of your success on the Choob. You are awesome!

I went through ATC school in the Air Force and it is said to recognize that there are aircraft taking off in front of you that cause wake turbulence when taking off. There are FAA regulations on distance and airborne when the next aircraft can be cleared for take off. Wake turbulence is only a departure-departure "crime" and not issued on landings.

Once I read a definition of stress as, "Coming in to land at a large airport in a small plane, with a maximum speed of 140 MPH, followed by a commercial jet with a stall speed of 140 MPH." I don't know how accurate this is, as I'm sure there would be sufficient separation managed by ATC.

I learned about wake vortices from that. In the US Navy I was stationed on the British Indian Ocean Territory (BIOT) of Diego Garcia. There is an air base there and running paralell to the runway, but a few hundred feet away is a road. I'd ride my bicycle along that road for exercise. One lovely, sunny tropical day I heard the rumble of a B-52 taking off, and I knew it would be heavy because, taking off from a 'middle of nowhere' surrounded by thousands of miles of water all B-52s that departed Diego had to go fully fueled. Just before it passed me it started flying (B-52s don't really rotate, they just start flying) and a few moments later I was blasted off the road into the sand by its vortices. Believe me, they are really powerful!! It was like stepping into a hurricane.

I will never forget that time when I was on a flight landing in LAX. As we were approaching the airport, all of a sudden the plane tipped over to the right at a 90 degree angle. I was staring at the roofs of these houses straight down. We all screamed and thought we were going down. We recovered shortly after and then the pilot came onto the PA announcing it was weight turbulence. That was how I learnt the term. It was horrifying and I hope never in my life again.

Another great video. One thing though at 07:30, you can't always go around if you inadvertently fly into vortices from a 'heavy' as you may well not have enough control authority and no choice of where the aircraft will go. I remember being a student solo pilot in a C152 awaiting departure. A C130 Hercules 'heavy' took off and seconds later the tower cleared me for take off. Although I was fully awhere of the issues of this video, being a fresh new pilot and not wanting to upset anyone I slowly and cautiously taxied into the runway and lined up. I took my time but it had only been a minute or so... I opened the throttle to full and (just about) felt those little ponies pull me as hard as they could. I easily got airborne far befor the C130 ahead and climbed out. However I'd noticed the C130's climb angle was far greater than mine and when I was at a couple of hundred feet still above the runway on the upwind leg I intersected (found) his wake! Now I'm a very confident pilot who very much enjoys seat of the pants flying and throwing aeroplanes around the sky, but I will fully admit to not liking that experience at all! It was the lack of control and just being totally and dangerously blown around at extreme attitudes against my will despite all my corrective control inputs... After several seconds I had very clumsily traversed through this huge wake and my C152 started to fly normally again. I had learnt my lesson and then know, if you have reason to stop or wait, just talk to the tower and ask for separation!

Do winglets have a significant impact on these turbulences? If so, is this even reflected in the categories?

Hey joe, how the fighter jets elude this wake turbulance?? Because I saw group of them flying really close in different formations in many videos..

I'm not Joe, a pilot or an engineer, but I am read up on military aircraft. Most military fighter jets are inherently unstable, which allows them to make sharp turns. However, it means that humans are not able to fly them on their own. As a result, they have flight computers that automatically adjust the control surfaces to keep the plane flying as instructed by the joystick inputs. This takes into account the inherent instability of the fighter jets as well as any turbulence that the plane may encounter.

Seriously I really learn a lot from Captain Joe's explanations . as often as I've flown commercial or private I have often wondered about a lot of things that I know are going on but do not understand. he answers those questions for me. even though I am a layman-nonpilot I do have and interest and do care. Thank you Captain Joe for taking the time to do these video's even for us "poor souls" that sit on board trusting our pilots and copilots.

8:00 There's "high tow" as you describe, "low tow" where you fly below the propwash. Sometimes preferred as there's less danger to the tug pilot (if the glider pulls up, it lifts the tug's tail, sometimes causing a fatal dive). Training exercise is to "box" the tow plane's wake. Also to fly into the wake so the trainee knows what it feels like to sit there. Do you put minor mistakes into all the videos so folk can pedantically correct/expand in the comments and drive up engagement?

A glider flier a little higher that the tug plane so that it does not get destabilized due to the wake turbulence of the tug plane. Also this is why the tail horizontal stabilizer (the one with the elevators) is sometimes placed higher than the main wing or have a dihedral or anhedral to get out of the way of the wake turbulence caused by the main wing.

So, comment from a dumbass meatbomb (skydiver), when we fly multi plane drops, the rear aircraft sits slightly BELOW the lead aircraft to avoid wake turbulence and falling into the dead air (cavitation), if anyone remembers the vids from a few years back where two jump planes collided while jumpers were climbing out? Rear craft was aft and up of lead craft. Is this not the same for gliders due to aspect ratio/wingspan/other fluid dynmagic? *Edit* still not clear on this, I'll shut up and do some research!

@charles becker Tailplane anhedral is used to increase pitch down elevator authority at high angles of attack, high alpha in todays parlance. It ensures that at least part of the elevator is not in the dirty air of the wing, so the answer to your question would be yes. One of the best examples is the F4 Phantom. A T tail has the same effect and is fitted to a large number of modern gliders for that reason and it lessens the opportunity for damage when landing out in unprepared fields.

Is this why the Martin flying boats of WWII had such a severe dihedral in the horizontal stabilizer?

The glider flying above the towplane to avoid wake turbulence is not strictly true. There are two positions, high tow, which is just above the prop wash of the tow plane, and low tow which is just below the prop wash. High tow is normally used for launching and low tow used for cross country tows. Personally I remain in high tow for the early climb and then switch down to low tow for the climb. With modern gliders the low tow position tends to be more stable and lessens the likelehood of losing sight of the tug, very bad news as the immediate action if you do lose sight of the tug is to release.

Most modern gliders have their horisontal stabilizer mounted high for several reasons, main reasons being: 1 - Fewer parts and simpler connection / control hook-up when rigging/de-rigging 2 - Simpler structure = lighter parts 3 - Out of the way relative to tall grass / ground obstacles in the event of an outlanding and general ground handling. 4 - Stabilizer is kept outside the turbulence coming off the fuselage & wings. The tug do create wake turbulence but the glider need to be below the tug in order to feel it. The ideal position of the glider relative to the tug is in the direct line between propeller axis and tug stabilizer. In this position the tug pilot will feel very little, if any, vertical pull from the glider trailing behind.

I was in an A320 back in 2010 and we hit wake turbulence at high altitude. The plane dropped so fast that some passengers flew up from their seats. It was pretty scary mainly because there was no warning.

When doing my first solo in a T6 Texan I did a loop and went through my own wake at the bottom of it. It scared me half to death because I had zero clue what just jolted my aircraft. I told my instructors what happened and they laughed at me and was surprised I must have flown the perfect loop. Anyone else experience this?

Good explanation of heavy jet separation. However, contrary to your explanation of a turboprop departing after a heavy, there is also increased separation when departing behind. Generally 4nm heavy after a departed heavy. And 5 nm for others after a departed heavy. Also, 2 minutes time may be used, but controllers usually use the RADAR separation as it is usually more efficient. If the pilot wants the 2 minutes, they should advise the controller BEFORE taking the runway.

The day before an airshow several military aviations enthusiest and I were very close to the end of a runway where a C-5B Galaxy and AN-224 Mriya to fly in. Although we were in an unrestricted part of the airbase we were subjected to very strong gusts from the aircraft about 20 seconds after the airplane landed. The Mriya is the worlds heavies aircraft and it's wake turbulence was phenomenal even when you stand 1000 feet from the end of the runway. One guy standing on top of his truck got pushed off by the wind but fortunately was not injured. I miss the yearly airshow since that airbase was decommissioned.

Something which may be of interest also is these compressor rotor blades are manufactured from materials in their raw form. This allows the rotor blades to utilise the strongest covalent bonding of the materials at a molecular level. The result of which is the strongest rotor blade possible. Just a little thing I recall from my BGT theory days.

This raises a very interesting point I hadn't ever considered. As the airflow passes beyond N1 and is compressed along the many stages of rotors and stators the blade tip vorticies must be immense and many to produce the lift/thrust that they do, especially as the compressors rotate introducing inertia of the airflow being spun away from the boundary layer of the rotor blades. Sometimes I'm just amazed and in utter awe of the engineering of jet engines!

Well, I do have some knowledge about how the wings create lift and vortices but not so much about the wing bending. The only thing I can say about it is that it heavily depends on the specific aircraft (size, type of wings, etc.)

Can fuel impact weight categorization? For example, if a plane that's normally on the high end of "medium" was attempting to land with extra fuel weight, could it add enough weight for them to declare themselves as heavy?
