Online visualization by Jason Davies presents the world organized as territories in relation to the distance between airports:
Each region is closer to a particular airport than any other. This partitioning of the sphere is called a spherical Voronoi diagram, and was calculated by d3.geo.voronoi, which is currently underdevelopment.
It takes a pressure difference between the top and bottom parts of the wing in order to produce lift. But when the flow of air becomes turbulent ( i.e during a stall ), this pressure difference is no longer established.
As a result of which, the lift drastically decreases and the aircraft starts dropping to the ground.
How to get out of a stall ?
Stalls can cause problems only when the pilot is not aware that the aircraft is stalling. ( Unlikely but has caused accidents in yester times )
As the airplane loses altitude, its nose dips down and airspeed picks up quickly. This restores the lift and the pilot would be able to regain control and bring the aero-plane into level flight.
How are stalls detected ?
On light aircraft there is a reed (much like used on a musical wind
instrument) mounted on one wing root, which is angled such that at the
Angle of Attack which would cause a stall, the reed “plays” which can be
heard in the cockpit.
Here is a view of where this system is mounted on a Cessna
On some aircrafts, it is a similar principal, however instead of a
reed, it uses a fin which at critical AoA pushes a micro-switch which
activates a buzzer/horn inside the cockpit.
Here is the assembly on a Beech 18
Large commercial aircraft typically rely on either Angle of Attack (AoA) Vanes or Differential Pitot Tubes to supply input to flight computers for the purpose of calculating AoA.
A lot of important stuff regarding aerodynamics in this post. Here’s a summary of the post:

That’s all folks!
Hope you enjoyed today’s post and learnt something new.
E naquela madrugada ela voltou a ser a garotinha de 10 anos que se esconde chorando embaixo das cobertas com o intuito de se proteger dos monstros imaginários, mas dessas vez ela não conseguiu se proteger dos monstros, pois o único mostro existente naquele quarto era ela mesma, com suas inseguranças e pensamentos grotescos.
One of the hardest parts of establishing and maintaining boundaries is our fear of appearing rude or selfish. Your quest for boundaries hinges on your willingness to take care of yourself so that you can be there for others. This does not mean that you are dismissive of others or their feelings.
A boundary is a space between you and another person. As the gatekeeper, you can decide how close another person gets to you physically and emotionally.
Healthy boundaries are a way to protect yourself, giving yourself freedom to conduct your life in a way that helps you flourish.
1. Healthy emotional boundaries mean that you are able to voice your desires and preferences. Your emotional boundaries separate your emotions from those of another. They protect your self-esteem. Examples include:
Your own health and well-being are important, and you will not be forced to neglect your own needs.
You have a right to be treated with respect.
You will not be manipulated or forced to do things you don’t want to do, even if the other person is attempting to make you feel guilty.
You won’t allow others to yell at you, make you feel bad about who you are or what you are doing, or call you names.
You don’t blame others for things that are your responsibility, and you don’t allow others to blame you for things that are not your responsibility.
You keep your emotions separate from other people’s emotions, although you empathize with the people you care about.
You convey your own needs assertively, and work towards cooperation if possible. This helps maintain mutual respect.
2. Recognize physical boundaries for your physical self.
When someone intrudes on our physical space, we feel it internally. It feels awkward and unnatural.
When you are in a relationship, make sure you are comfortable with how you express yourself physically with the other person. Have a conversation about what will make you feel safe and loved.
Northern Europeans and North Americans observe the largest personal space distance.
People in Middle Eastern countries, South America, and southern Europe have the smallest personal space distance, and touching is common.
Eastern cultures consider touching or patting on the back as taboo and offensive.
Physical boundaries are often described as personal space. Personal space includes physical possessions such as your home, your bedroom, your belongings, your car, etc. It is well within your rights to establish boundaries with others about respect for your privacy and your possessions.
