    Dear friends and followers, welcome back to my channel and to part 2 of our METAR video series where we’ll discuss how to read the remarks section and Trend Type Landing Forecasts or TTLs often found at the end of a METAR report. This is the part that can be most confusing even to experienced airline pilots.
    Beginning with our example from Los Angeles International we see the following added after the air pressure (RMK AO2 SLP121 T01610106). Our first key is RMK meaning Remarks. This is a standard code to display any additional or non standard information such as the strings we’re reading here or comments such as a NOTAM or Warning. Next we see “AO2” meaning that the station which took the reading is equipped with a so called Precipitation Discriminator Sensor which can tell the difference between rain and snow. If a station is not equipped with this sensor this remark will read “AO1”. The abbreviation SLP refers to Sea Level Pressure, in this case SLP121 would mean 1012.1 hPa. Note that a decimal is always given here which is unusual for pressure values in hectoPascals, in other words the last digit of an SLP is always a decimal unit rather than a whole number. We see this again with temperature in this code (T01610106). Looking at this at first may seem like gibberish but it is actually quite simple once you know what it means. The letter “T” designates that this is a temperature reading and is always followed by eight numbers to describe the temperature and dewpoint at the field. This code is used in America to give readings in degrees Celsius with more accuracy, again by providing a decimal reading. The first number shown will always be either a 0 for positive temperatures or a 1 for negative. Note that in the full METAR we saw the temperature listed as 16 degrees Celsius and the dew point as 11 Degrees Celsius. We can see in our temperature remark that the actual measurement was Positive 16.1 Degrees Celsius and the Dew Point as Positive 10.6 Degrees Celsius. It is debatable whether or not this information is actually useful to pilots during operations but it is there if you want it.
    Now in our example from JFK airport in New York we can see a few other remarks have been added so lets break them down. First off we know the meaning of most of the remarks section such as AO2, SLP and T but what about this new code P0000? This refers to Liquid Equivalent Precipitation which has accumulated in the last hour and is measured in inches with two decimal places of accuracy. In this case 00.00 inches have accumulated meaning that the rain discussed earlier may have dried out or the sensor may be faulty. Note here that the measurement is a liquid equivalent. An inch of snow may not show as P0100 but an inch of rain will. Our other new section (RAB09E23) describes rain at the airfield. RA is a standard abbreviation for rain, the B stands for Began and the E for Ended. In this case RAin Began 09 minutes past the hour and Ended 23 minutes past the hour. Note the issue time for this METAR was 150351 Zulu so the hour this Rain report refers to would be 0300 on the 15th UTC or 11pm local time on the 14th in New York. Another form of rain report you might find can be seen in this example from Alice Springs in Australia. This form uses the code RF meaning Rainfall and shows firstly the amount of rainfall in millimetres in the last 10 minutes and second the amount of rain at the airfield since the last time it was 9am again in millimetres.
    Thank you very much for your time! I hope you enjoy this video!
    Wishing you all the best!
    Your "Captain" Joe

      I have decoded this METAR except for one thing. Please help!--4/011 after SLP KJFK 031151Z 32012KT 9SM -SN OVC070 M01/M05 A2948 RMK AO2 SNE14B45 SLP981 4/011 P0000 60000 70002 T10111050 11006 21017 53013 New York JFK, USA, weather recorded on the 3rd day of the month at 11:51Z time. Wind 320 degrees at 12 knots. Visibility 9 statute miles. Light snow. Overcast clouds at 7000ft. Temperature -1C, dewpoint -5C. QNH 29.48inHg. RMK-Remark AO2-automatic Precipitation Discriminator at field Snow ended 14 minutes past the hour and began again 45 minutes past the hour. Sea Level pressure 998.1 hectopascales 4/11 P0000 Precipitation last hour 0 inches 60000-precipitation last 6 hours 0 inches 70002 Precipitation last 24 hours 0.2 inches Temperature -1.1C Dewpoint -5.0 C Stuck on the 4/011 after the SLP and the last 3 numbers 11006 21017 53013 11006-1=highest temp over the last 6 hours = 1 means a negative number Temp =-0.6 C 21017 2- lowest temp over last 6 hours 1= negative number -1.7 C 53013 5 group is the barometric tendency over past 3 hours the 3 means the pressure has increased-On a scale of 1 to 10 5 means pressure unchanged 1 means pressure increased a lot and 10 means it has decreased a lot so here the pressure has increased by 1.3 Hpa

      I've been flying into JFK recently, coming from Europe. I've not been flying in the US for 16 years, so I have forgotten lots about it. Your video helped me to unravel quite a few mysteries of the METAR and TAF's I am seeing. Thanks!

    3. Me Here

      Hello el Capatain Joé Dooneeden is pronounced "Dunn-Edin" 😂😂😁👍👍🔧

    4. Nwazue Munachi

      Mhen even Captain Joe was so exhausted after this video.

    5. Mutahir Rana

      Your are well prepared mentally and physical . Because your voice tell . how you handle Your emotions and gesture . u better know we to little stop n where to make high n low pitch.

    6. Taj S

      Dunedin is pronounced Dun-eeden. But no worries captain😉

    7. Patrick Glosson

      I have a lot to learn but, at least now it's making somewhat sense

    8. Maldindu Wijayarathna

      Hey Joe, what does FM112300 01012 KT mean??

    9. Алексей Попов

      Hello Captain Joe, I'm still disappointed. What does that mean when a pilot saying to ATC ".... information CHARLIE on board", or India... I tried to ask google, but no results... feeling like all-around understands this, except me :(

    10. GarretTheShadow

      Great video! Could you help with the remark of the following METAR? METAR CYVR 141800Z 21003KT 190V300 1SM R26R/4500FT/N R08R/5000FT/N FU BR SCT002 BKN013 OVC029 15/13 A2998 RMK FU3SF1ST3SC1 SLP153=

    11. Nolan Antonello

      Very confusing but also very helpful I have watched both videos a few times and I am starting to understand the meter

    12. Francesco Barbini

      What does RE means? (For example in RERA)?

    13. Username

      These reports are actually ridiculus

    14. Reuben Mclord

      Am waiting for Elon Musk to manufacture a plane where everything will be shown on a big screen with less buttons to press 😁

    15. Chester Wang

      I wish school showed this for flight. They teach horrible things for flight. Way too easy. They teach the “equal transit theory” for flight which is wrong because the air does’t have to meet at the other side of the wing at the same time

    16. D E

      Don't all these stunted short codes increase the risk of misinterpretation/confusion? Then add the barmy mix of metric and imperial measurements! They should be talking to humans in human language and not mixing up metric and imperial!!!

    17. 2E (16) Yuen Chung Lam Ivan

      It's complicated, but I feel like I learnt a lot. There's so much to learn in aviation.

      Thanks sir 👍 I really appreciate this video I been looking for the topics a while on web....even Mr Joe you didn't give my comment a heart Lik the others .... thanks again sir for yr help I found this metar Lik on KMSS us cause i do my Ifr Multi on Cycc near my school home on css3.

    24. luis antonio diaz lozada

      Well Captain Joe we need more of this videos .👍👍😃😃🥇

    25. santhosh manikandan

      Sir speak about the need of spinning wheel in cockpit. Trimming wheels

    26. Monoplayz

      Thx captain I have gained -12 brain cells

    27. Robert Thrailkill

      Have been a private pilot in the USA for 30 years and always wondered what the extra numbers indicated. When I asked my flight instructors they always said it was not useful. Well, seems like it can be useful sometimes to me. Thanks!

    28. Starman2319

      Thank you for your work on this, Joe. Looking forward to TAFS decoded :o)

    29. Que Rico Cocina

      a good pilot is always learning ... thats signature frase from MZeroA making videos since 8 years ago in every video

    30. Mariliese Julianne Enriquez

      Can You please fly a Concorde pls like if he should

    31. alab_9507

      Start a Pilot Vlogs seires. Show us what you do while flying and show us where you go in the world. If your up for it of course. I love watching your video's and I think this would be fun to watch

    32. Skills Magee

      Please help me achieve my dream of being an airline pilot

    33. Maksuda Begum

      hey joe do aircraft needs oil change?

    34. H0ku

      Can a male pilot have long hair?

      1. H0ku

        ZK-APA But if women can have long hair, why can’t men have long hair?

      2. ZK-APA

        Andrin depends on the company policy. Generally airlines have a grooming policy, but private pilots can keep what they like.

    35. Skandar Skandar

      What happens when plain has been terrorist attack and air marshal can't do anything? Please explain this to us 💝

    36. Amitesh Gupta

      Hi Captain Joe, Can you please make a video on the runway length required to land A320 on wet and dry runways with various glide slope approaches. Also please consider both Flaps 3 and Flap full configuration.

      1. ZK-APA

        Amitesh Gupta it all depends on the variables of the runway at the moment, as well as the runway dimensions too. In some conditions you will be able to use both flaps 3 and flaps full (or even flapless, though that’s a flap failure situation only). But in others it’ll require flap full to safely stop.

    37. Yashmeet Malviya

      JOE Can you make a vidio on : weakest parts of an airplane

    38. Umar Abdulhamid

      Sorry for the late wishes. Happy birthday to the person that inspired me and the to me the best pilot in the world. Happy birthday captain Joe on your 35th birthday many more bless years to come to the man that inspired me and motivate at always I hope that we speak in person. Cheers enjoy 🍻🍷🍺

    39. Sahil Bhere

      Sir, I love seeing ur videos.... Sir I want to know that what does DGCA contains.... So, pls sir can u make video on what does DGCA contains

      1. ZK-APA

        Did U Know he wouldn’t be able to make that accurately as he doesn’t operate under a DGCA licence (which is unique to the country)

    40. Paul1962

      Not a flight i was on, but love to know your thoughts

    41. Benjamin Powell

      Im glad i watched this. Ive always assumed the remarks codes were not useful...i was right.

    42. Danial Raja

      Hi captain Joe. I love watching your videos because they are very helpful and full of great knowledge so thank you so much for making helpful videos like this. I had a question regarding the Boeing 747-8I. The Boeing 747-8I has two elevators that are split into two. Why are the two elevators split?

    43. Alyx

      Joe.. are rims on an airplane still so called ''rims'' or are they called something else?

    44. Henry Allan

      If you are studying Engr..Decoding is very Easy

    45. Luke M

      Hey Joe do you think now is a good time to start training despite corona I've been accepted to a flight school

      1. ZK-APA

        Luke M right now it’s a very low point in terms of aviation. Sure it’ll recover eventually but right now it’s not. So ideally right now won’t be the right time. However, if you are financially very stable and have a genuine passion for it, then you can think about starting now. Just remember to keep your expectations low, and hopes high as there will be a bit of struggle.

    46. McrsftHater

      Damn! Do you remember all this information? That must be hard)

      Captain do airplanes carry a spare wheel?

    49. fortnite kiddie

      Are you from Germany or from England?

    50. Ein echter Weaner

      Hey Joe! I saw in a METAR R07/90//95. What does this mean? Thank you in advance for your answer!

    51. BAIBHAB B

      Hi could you tell me more about your morning routine please

      1. BAIBHAB B

        I know

      2. ZK-APA

        BAIBHAB BHATTACHARJEE he’s already made a morning routine video

    52. Arron Metcalf

      Perfect timing! Just went over these in my PPL training! Well explained, as always :-).

    53. FlyingBread

      HAPPY BIRTHDAY CAPTAIN JOE!!!! 🎂🎉🎈. ( I'm sorry for the late message it's 22nd June in my time zone xD )

    54. Nathan Blackmer

      If I’m a passenger, and I see a pilot doing the walkaround, and their flashlight goes out, can I shine my very bright light at whatever they need to look at? Or would that be weird?

    55. Boeing777x

      Happy birthday captain joe.

    56. Jacobo larin

      Teacher can I go to the bathroom

    57. Carlos Domingo Más

      What if preassure is < 1000 hPa? How would SLP be? @ 2:40

    58. uruaviation

      awesome vid!! , yesterday i did my first night flight in a cessna 150 , if u want to watch it you are welcome!!

    59. Gala Denzel

      Thank you so much!

    61. JReastHei

      Hey Captain Joe, off topic here but check this link out; A photographer in Hong Kong snapped this awesome picture of the queen flying through the rainbow;

    62. Nicat Xudaverdiev

      Hi,Captain.Why the LRJT trim sheet has slanted ladders? but in MRJT they are direct?

    63. Hondalover3000

      You're always good on technical explanations made simple Captain Joe. The next tech video I'd love to see is how the mechanics in these aircraft work during a rotation. Thanks Capt Joe.

    64. Chris Everett

      Wow complicated. Needed a second view of parts 1 and 2

    65. RG T

      I had forgotten why I egnore the last part of the METAR, now remember...thanks:)

    66. MRV 07 07

      Omg this is tough But u r GREAT Sir LOVE FROM INDIA 💕

    67. Random Man

      Ah. Captain Joe is now back to live!

    68. Aziz Sahabei9o9

      What flight school did you go to

    69. Bob Brewer

      Hi Joe, As weird as it might seem to you of rain in Alice Springs, the whole of Australia does, in fact get some rain. The coastal areas definitely get it the most, the further inland you go, the less there is, but desert areas definitely do get some.

    70. Rahul Satghare

      Before watching this channel : why the hell these pilots are getting tons of rupees in salary..? After watching this channel : I got the answer..! Tough job..

    71. Dreamjob Pilot

      My head at the end of the video 🤯

    72. Alex George

      If a TCAS tells you to descend but the ATC controller tells you to ascend who should you listen to?

      1. Pilot Interview Handbook

        TCAS. You don’t want any misunderstanding at this point :)

    73. Igor Alexandrovich

      Joe, where is DPG? )))

    74. Fernando Castillo

      Hi Captain, I just watched this video about engine test with people close and I wonder can an engine suck a person? Cheers from Mexico :D

    75. Connor Edwards

      Here from the link on "Explaned"

    76. Panda Azmore

      Its weird how I want to be a pilot but I have never been in a plane Can I make it Captain Joe

    77. Thomas Dalton

      How does the SLP work if the pressure is below 1000 hectopascals?

    78. Mike Fischer

      Going through ground school for my ppl, I remember this METAR madness and I thought, OK, i get it, this is how you make me question how bad I want to be a pilot! (It’s worth it.)

      1. Username

        Yea, I'm doing my PPL now. The theory is all so easy and then suddenly you get to this - it's terrifying

    79. Igor Alexandrovich

      So interesting, but sooo difficult and puzzled, i almost got a brain explosion😁

    80. Hassan Mohammed

      Great video cap I have a question: if the metar is faulty does this affect the landing and can cause a diversion?

    81. Dr. Med Kit

      Indian 🇮🇳 Captain and KGupr @Flying Beast got suspended since he was raising concerns about company's security measures and policies like imposing flap 3 landing for cost efficiency. Please give your opinion, how risky the concerns raised by him are. #FlyingBeast #SabKeLiye

    82. minchuballi

      Dear captain Joe i am a big fan of you I am12years old and my ambition is to become a pilot and I request you to make a video on the world's best airlines or pilot training school I hope you will respond to my request thankyou and this video is awesome👌 bye...sir🙏

    83. daily8150

      Gosh! I have learnt so much from all of your videos, as a passengers in an aircraft. Thank you.

    84. Itay Saadon

      6:05 why 9 am? And how is that helpful if let's now is 8 am the day after?

    85. rameshwari saxena

      We can become a pilot after seeing sir videos

    86. Ehud Gavron

      Very instructional. It would have helped me gain my CPL-H! If you ever want to discuss weather patterns (troughs, highs, lows, etc.) that would also be appreciated! *goes to buy keyring*

    87. Remain Blessed

      Something for you Captain Joe?

    88. Pgcmoore


    89. Sierra Papa

      Execellent presentation...

    90. Alessio Frigerio

      It's much more difficult to learn decode metar than fly.

    91. Aviation Pro

      are there any kids that watch these video because it is their dream to become a pilot.

    92. Gill Jenkins

      Great video Joe, I think everyone from NZ fell off their chairs at your mention. I had to laugh that Auckland had a variable weather notification. The weather there is so changeable we joke that if you don't like the weather in Auckland just wait 5 minutes and it will change. I wonder if it ever DOESN'T have a variable weather note 🤣

    93. Aquahands

      Thanks for helping us out, your explanations are more clear than what I normally get from Google.

    94. Marti Mei

      Nice video - a bit too complicated for me!

    95. fair xing

      The best part is "Your captain Joe" 💜

    96. Brad R

      Dunedin is pronounced "done Eden", not "do need in" :)

    97. Frank Witsel

      Hi Joe, great info! Thanks for all your very nice videos! As a PPL pilot I never saw this additional info before and I have a question about the SLP121. I do understand that this refers to 1012.1 hPa but what if the pressure is 952.1 hPa for example? How is that displayed? Because it is possible (ok in very extreme conditions) to have 1052.1 hPa

    98. ULTRA

      When you went over the YBAS metar and the RF00.0/000.0 format, i immediately thought of the monotone voice of the awis at YSDU, "rainfall, last 10 minutes, nil"

    99. Pascal Broede

      that is too complicated for non-pilots.

    100. Dean Sartorel

      In Australia, TTF’s are valid for 3 hours, is it different in other countries?
