You are the only one I've found on the internet so far that has this correct. The one thing I would point out is that in some airliners there are, in fact, angle of attack indicators.
Concise and clear, but not quite complete. I mean, I have to keep looking for a more in-depth explanation going into the nitty-gritty of, e.g., how the angle of incidence improves the lift, etc.
2:14 Well if the pilots don't have any information about angle of attack what does angle of attack sensor stand for ? is the data of the sensor not shown in the cockpit but sent to the flight computers for certain calibrations and preventive cautions ? or is the pitch angle derived from angle of attack sensor or gyros in the aircraft ? I am confused
The Angle of Attack information is sent to different computers on board the aircraft, which trigger certain actions, most notable of which would be the STALL Alert or Stick Shaker!
please, how does an aircraft react to the loss of weight due to fuel consumption? I assume that, in the first place, the "angle of incidence" is chosen so that the airplane, with half of its fuel weight gone, flies at an optimal condition, i.e. with an angle of incidence = 0 (in mid-flight), using just the airfoils lift due to its profile and its "angle of attack", without using flaps, slats or any other control surface. but what does it do in the non-optimal states of a) full fuel weight and b) fuel weight down to reserve? in a) it may fly at an increased pitch angle to the flight path or it may use slats and/or flaps (?) and in b) it may compensate for a surplus of lift (with speed constant) by using the flaps in an upward bent position (?) or by flying with a negative pitch angle (or reducing speed)... what's the case in reality please? thank you!
The aircraft is constantly trimmed by using trimmable surfaces to cater for the changes or disturbances that occur in flight. The angle of incidence and the twist in the wing is chosen so that the aircraft flies optimally within its normal loading configuration.
The fuel for most commercial aircraft is held in the wings, which closely surround the centre of gravity, and (of course) determine the centre of lift.. So as the fuel is used up, there is only a minimal effect on the ideal angles of attack or incidence. If the fuel were stored in the fuselage in front of or behind the wings, the effect of depleting it would be considerable.
the usual definition of the aoa is in respect to the cord of the wing, not the longitudinal axis of the plane (since the angle between relative wind and wing cord is what counts for lift and phenomena like stall). if one defines it relative to the longitudinal axis of the airframe one would always need to add the angle of incidence too to get the relevant angle, which would be unpractical. what a pilot wants to know is the angle between wing chord and wind - and that is also what aoa displays show where they exist and what flight augmentation computers use to calculate how close one is to alpha prot etc. for certain corrections one of course also wants to know the aoa between airframe and relative wind (for example corrections in the dynamic pitot measurements). i would however hope that we do in general understand aoa as angle between wind chord and relative wind.

Oh Cool! Thank you for the info! Do check out my other videos as well!
The most complete and concise video on the topic.. ty 🏆🙌🏻☝🏻🇺🇸✈️🛩️🥇

It is better to Explanation than Teacher Its Really Best for me!

Thank you for the answer@@JxJAVIATION
Nice explanation keep bringing such videos. Very helpful for gaining knowledge
Thank you, and Keep watching!

Please Sr ,you can talk about the three levers and Flight control unit
What is meant by three levers?
@@JxJAVIATION fuel lever ,propeller lever and power lever
Sir please make a video on BANK ANGLE,TRIM ANGLE & ROLE ANGLE.
Sure. Will do one on these topics soon!
excellent

Can the airplane have 0 degree angle of incidence..?
by pitching down, it is possible
