    As a child my dad was on B52 flight crew when we was stationed at Ramey AFB Puerto Rico. We used to set in lawn chairs on the front porch, he would do mach flights and talk me thru everything. Watching your videos reminds me of those days. I was only 5 but remember it well. My dad passed in 2009 so your videos bring back fond memories. Keep up the amazing videos.

    Great channel! Just discovered it recently and have enjoyed watching all your podcasts over the last couple of weeks. As you are discussing failures now i thought it would be nice if you could discuss the use of a risk management model (ANC, asses, action, manage, re-asses). You explained nicely how to identify and deal with a failure so it would be nice to see how the crew proceed with the flight once the failure has been dealt with. For example, company needs vs. crew needs vs. passenger needs, maintenance bases, aircraft serviceability and deciding whether to divert to a suitable alternate or press on to your destination.

You help many aviation enthusiasts around the world. I don't know if anyone has suggested this but landing gear failure and manual extension, IRS failure, fuel leak? Thank you so very much again and don't worry soon your channel will have many more viewers because it is really unique!

    Yes way back in the 70s, there was an eastern airlines flight heading to Miami and I think there was a problem with the light that indicates whether the landing gear was down or not. Someone disengaged the autopilot by accident and everyone was so distracted that the plane crashed into the Everglades.

    The information you provide is fantastic. With aircraft failure it is often the smallest thing that causes disaster. My concern is how aircraft are pushed to be constantly in the air. In a few weeks I'm travelling from London to Australia. The aircraft has a two hour turn around before heading back to London, then about six hours before departing for Australia again. Doesn't this put a huge amount of stress on the aircrafts structure and be the cause of stress fractures that eventually and suddenly have catastrophic consequences.

    hey, why is the master caution button on a 737 always twisted for a few degrees clockwise? It never aligns up with the fire warning button in a straight line. When first I noticed this, I thought someone must have done a sloppy service or something, but even the PMDG 737 in FSX has this button slightly rotated.

    Dear Mentour, first and foremost, thank you ever so much for your podcasts and for guiding me through my first airline job. Believe it or not, you have been a role model throughout this process - it hasn't been easy I can tell you!
    Now to the question: I'm currently undergoing initial type rating on the B733, and there is a memory item that I am having troubles identifying: Engine Fire v.s Engine Tailpipe Fire. According to the FCTM and QRH, it specifies that the Engine Tailpipe Fire is caused by flooding of the combustion chamber and that you won't receive a Fire Warn indication. It also says that the engine fire extinguishing agent will not be effective, which in turn directs you to cutoff the engine selectors and motor the engine instead. Why am I concerned? Mainly because I don't know how I would recognize the fire if I don't get any Fire Warn indication, and if the tower or ground personnel (skill test inspector in this case) alert me of the fire, I'm worried I would execute the Engine Fire memory item instead, which as you know would not help and would probably be disastrous in a real situation. Do you have any suggestions on how to differentiate the recognition of these failures? I hope this question won't take too much of your time and I thank you once again for your guidance.

    • @airborn86
      @airborn86 7 лет назад +1

      Actually I just realized that the engine fire switches will not illuminate, maybe this is the main indicator? If it isn't too much too ask, would you consider making a podcast about the different engine fires vs engine failures/surges/damages and how to recognize the differences? May sound obvious, but many of these procedures are similar, considering also the high pressure environment in the sim. Tack så mycket!

    Hi there, really appreciate the insight derived from your channel especially the technical topics you've covered so far. I don't suppose down the line (checklist pun intended) you could possibly do a short podcast highlighting the importance of decent management? I.e. Using different vertical modes accurately in hypothetical scenarios e.g ATC leaving you too high or too low or the profile is not according to planned etc? That would be much appreciated my end mate.

    Petter, I was watching a regional jet taxiing for take off at the Asheville regional airport, and I was shocked to see that the left engine had it's reverse thruster gear deployed ! There was no subsequent crash thankfully, but isn't that something on the pre take-off list ???

    • @MentourPilot

      Some private jets actually have to use the reversers while taxiing because of their oversized engine thrust.

      At V1, the captain would make the call either to stop if he still can, or take off and circle around. With 1 working engine they'd likely opt to circle.

    Pitot tube blockage, how common is that, and how hard is it do detect? seen a disaster video where the pilots got conflicting information cause the computer thought it was climbing and overspeeding when the throttles was close to idle. This was also a night flight over water so no references.

    Is there a way to perform a full-text search throught the checklists in a corporate iPad (or whatever tablet you guys have there)? Or at least for an imprecise search throught the index
    Were there a built-in diagnostic system, it could show you a checklist (and even perform some technical checks) immediately after a failure happens, I wonder what the aicraft software/hardware designers think about that

  • @NealeGray
    @NealeGray 6 лет назад

    I've noticed, as a passenger, that reverse thrust is rarely used these days. When I was flying (as a passenger) back in the 70s, 80s, and 90s, reverse thrust was used to stop the aircraft upon landing. Nowadays they don't seem to, or if they do I haven't noticed. Is that because planes have better brakes these days, or another reason? I once experienced an A380 using reverse thrust at LHR but that was the exception rather than the rule.

  • @MarkPurpose
    @MarkPurpose 9 лет назад

    G-reat! :) So, how do you deal with "air cond (zone temperature)" master caution warning? (while on the ground) I still did not found any logical solution including PMDG's 737 manuals (which are really detailed). When it appears (sometimes it does, sometimes it does not, under the same circumstances), when the plane is airborne, it simply disappears. I can fly with it in the sim, but I am quite curious to deeper understand this issue. Thanks :)

    direct way to the rest of the people. My hat off to Mentour pilot.
    I'm an Atco and ppl pilot. Using different simulators I try to train Abnormal situations on 737NG sim. On the V1 Cut scenario, the QRH and the FCOM refears to the MFRA, ( minimun flaps retraction altitude)
    I'm unable to find which altitude is that, and how to find out the proper MFRA for any departure, Engine out Sid scenario.
    Any clue on that?

    I have two questions:
    In what instance(s) are you trained to abort a take-off after V1?
    Also, I realise that Boeing and Airbus have two very different approaches when it comes to the A/P and caution systems. Boeing tends to trust the pilots more; Airbus gives more control to the A/P. What is your opinion on this; who do you think is right?
    I thoroughly enjoy watching your videos, and you're, by far, the most interesting channel on RUclips (in my opinion), as I am considering becoming a pilot.
