    I wonder how this factors into combat. Would focusing on one type of airspeed over the over ever be advantageous or anything like that? What kind of speed shows in a fighters HUD?

    But, what is the airspeed velocity of an unladen swallow?

  • @pilottadeus3748
    @pilottadeus3748 Год назад

    If the static pressure decreases with altitude too, shouldn't these forces cancel each other out? So shouldn't the difference between the total pressure and the static pressure remain the same, thus showing the same airspeed?

  • @Gainsforlife

    Nice explanation but what about the lesser known "flat earth speed variable" where the pressure changes with altitude are factored into mach calculations using the flat earth formula. The formula accounts for the expansion of space and the moons effect on gravity as well as the pressure exerted on the atmosphere. This allows for a far more accurate reading of TAS and IAS in real time

    I never understood how you're supposed to know your pressure alt for your crusise performance chart I thought pressure alt is when you set 29.92 in the kollsman window. How are you supposed to get that pressure alt when you're still on the ground ? Any help would be appreciated.

      “ Believe it or not, both of us use mach number.”
      He’s saying both jet pilots and GA pilots have systems in place which calculate your speed as a percentage of the speed of sound. That’s mach number.

    Hello, Sir, I have a question. Is it possible to know the speed of the aircraft if we only know the distance and time that the aircraft will be arriving? Since my problem did not mention other conditions, can I just the formula V=d/t?

    Hi! Question:
    During the example video that starts at 4:39, I noticed that the airspeed indicator on the left doesn't seem to move or change at all. I found it kind of odd that it wouldn't be jumping up or down slightly, due to turbulence. Why is that?

  • @mba09freebord

    I don’t understand the difference between GS and TAS.

    • @rmbb1981
      @rmbb1981 4 года назад

      Does it have something to do with that if you climb at a constant rate you will move through the air perhaps at the same speed as you were at level flight but you’re now not moving as fast in relation to the ground?

  • @alexmp3821
    @alexmp3821 3 года назад

    Great video. I have a question, in FSX using Boeing 737, I was descending, at 9,000 feet my indicate speed is 250 but TAS was 305, so I was wrong because flying over 250 TAS according to the rule?

    • @Micg51

      250 indicated. We don’t care about TAS other than for planning purposes.

    These are always great and informative. It would be awesome if you started doing like a CFI series and explained in detail different aspects of lesson plans ie; aerodynamics, weight and balance, flight controls, ect...like an extreme breakdown of the PHAK. Anyway keep them comming, this is going into my CFI lesson playlist

  • @stevem6711
    @stevem6711 6 лет назад

    Interesting - for flight above FL200 in an unpressurized aircraft, the AF requires 30 min of pre-breading on 100% Oxygen prior to exceeding 16,000 feet. The maximum time spent between FL200 & FL240 is 110 min. This is to minimize the chance of decompression sickness.

    Great video, as always! Quick question: Why the facemasks rather than the nasal cannulas for this flight? Just curious as to what goes into the decision of which oxygen delivery system to use.

    • @spencerbrown3875
      @spencerbrown3875 6 лет назад +3

      Echin0idea You use the nasal cannula when flying between 12,500 and 18,000. Above 18,000 requires the mask.

    • @rex669
      @rex669 6 лет назад

      Chris Estabon you don’t really need a collage degree anymore with the pilot shortage going on. Just need your hours. However look into what carrier you want to fly for. Also combined collage and flight training can be a easy way to pay for flight school and collage with student loans. You do have pay that back with interest of course so can cost you more in the long run and the degree isn’t going to guarantee anymore pay for any job you’re starting with. However most major airlines still do prefer 4 year degrees.
