  '''Intro - Where it all have Started'''
  The beginning is always a delicate matter.
 
  It has been true for each one of us debuting and struggling with our plane,
  the same it has been to design the LILO-LOWI-Adrenaline "parcours" ...
  and the writing of this article just took several missed approaches !
 
  We all have been at that point, is it not ?
 
  Landing ... We all did manage to bring the plane back on the ground ...
 
  [[File:RWY-Excursion at VQPR-292-978×549.png|978x549|frameless|Excursion at Paro (Buthan)]] [[File:800_Thirsty_Horses_-_screen-009.png|978x549|frameless|Missed Taxiway]]
 
  But doing it in a way that leave us satisfied demand a bit more practice
  and knowledge too.
  '''Never give up!'''
  I did not give up and tried with patience many flying configurations, weather,
  weight... The results was continuing average.
 
  My search for explanation led me to find an amazing explanation by a retired flight
  instructor ! Crazy simple sketches and just a few words but very clear !
 
  Of course, any student aerospace engineer will surely study the same with way higher
  detail. But pilots and engineers are different and it this, and it is where Rob
  explanation earn a strong point !
  '''Landing is not continuing to descend until the ground - it is a controlled stall'''
  My 1st reaction was : "...no... no ways !"
 
  But the doubt got quickly away !
 
  Figure out a little motorboat changing direction :
  (view from top)
 
  [[File:Landing - Explanation - 1.png|361x264px|frameless|Landing - Explanation - 1]]
 
  blue - the '''''wished''''' direction ;
  red  - the '''''obtained''''' track.
 
  · Ground : a car would obtain an almost immediate "turn".
  · Water  : water is  elastic, you "drift" to the "wished" track.
  · Air    : even more elastic, more drift for the wished track.
  (view from Side)
 
  Same rule,
  the plane do not '''''"change  immediately  direction"'''''
  because of the ground.
 
  [[File:Landing - Explanation - 2.png|361x264px|frameless|Landing - Explanation help - 2]]
 
  The plane accumulate energy during the descent.
  When he touch the ground,
  the not completely "used" descent energy
  will tend to push the plane <big><big>'''''lower then the ground !'''''</big></big>
 
  Is it bad ?
  Well, that is why you have gear shock absorbers... but :
 
  Gear shock absorbers cannot absorb any infinite amount of energy,
  they have limits.
 
  If the "remaining" energy is '''''still too much''''' :
  - or you have a crash and a belly landing ;
  - or a "bump bump bump" and then probably a crash too.
 
  [[File:Landing - Explanation - 6.png|361x264px|frameless|Landing - Explanation Help - 6]]
 
  If this happen, put MAX THRUST and Go Around !
  If you do not, and you survive, you are going
  to be known the rest of your life as '''''Captain Kangourou'''''.
 
  Another crash will happen if you stall from too high.
 
  [[File:Landing - Explanation - 5.png|361x264px|frameless|Landing - Explanation Help - 5]]
 
  Gear shock absorbers can absorb this.
  '''The Proper way'''
  Rob was writing something like ... :
  ----------------------------------
  "This energy that in the air is your friend,
  on the ground become your enemy".
  Leave this energy there, exhaust it !"
 
  [[File:Landing - Explanation - 3.png|361x264px|frameless|Landing - Explanation Help - 3]]
 
  That is why we "round up", "we retard", "we flare".
  Landing is never direct.
 
  When descent energy is "ended" then you become
  able to land, brake, steer and control your plane...
  So, what is the "proper height" to stall ?
  "Any height that can be handled by the landing
  gear shock absorber."
  "But, ideally, from 'Zero' feet above RWY."
 
  [[File:Landing - Explanation - 4.png|361x264px|frameless|Landing - Explanation Help - 4]] 
 
  The butter landing !
  <big><big><big>'''''Conclusion'''''</big></big></big>
  Stall is at the "edge" of the "safe flying",
  not in the middle of the average safe flying envelope.
 
  That is why my landings was not so good.
  Knowing the edge, the limits of our plane is crucial.
 
  And this led me to the idea of a place where we could try, discover and test
  our plane, going at the edge, to the limit.
 
  Very low level flight, at '''''relatively high speed''''', we have tried,
  the Adrenaline is at the Rendez-vous !
  <big><big><big>'''''How is "this" related with LILO-LOWI-Adrenaline and Fun ?'''''</big><big><big></big></big>
  '''LILO-LOWI Adrenaline''' is a theater where to explore and train your pilot skills "at the edge."
 
  "...No one will do this "in the real life..."
 
  Actually, this is not so sure.
 
  In real life, pilots have to train to react appropriately in extreme situations.
  And yes, you already got it, they do it not in the real plane but in simulators !
  Well, here in Flightgear, it does seems we already have the simulator.
  What still was missing was a theater to train at the edge...
 
  Now, with LILO-LOWI-Adrenaline, we have it !
  One could argue within himself, "yes but for the small planes only..."
 
  Well, small planes is the best way to learn the "habits" that save your life
  when later you fly a "big plane".
 
  All the real life pilots :
  - "Gimli Glider, Captain Robert (Bob) Pearson, Air Canada flight 43, at Manitoba,
      zero loss and minimal damage to the plane ;
  - Captain Tadeusz Wrona (+officer Jerzy Szwarc) - belly landed the B767 with no
    injuries to anyone (LOT Polish Airlines Flight 16, Nov 2011) ;
  - Captain Chesley Sullenberger (+officer Jeffrey Skiles) accomplishing that
    controversial but impossible landing on the Hudson river (US Airways Flight
    1549);
  - Captain Carlos Dardano (+officer Dionisio Lopez) achieve a dead stick landing
    on the grass levee at Michoud (New Orleans) May 1988 (Taca flight 110) ;
 
  all off them have, of course several things in common, but one have called for
  my attention : countless hours of flight in small plane with the habit to take
  their small plane at the edge.
 
  If you still have doubts, think, is their out any aviation company or flight
  school that spent heavy money to train edge or extreme situations ?
 
  Not really, some company do it but they have started only after already lost
  so many lives !
  So, this is what have driven me.
 
  The creation of a theater where we all could exercise at the extreme and
  with a bit of chance and perseverance become better "virtual" pilots.
  My 1st idea was to call it  '''''"Disengage Auto-Pilot"''''' .
 
  But the first tries run by myself and others in the meanwhile I was designing the
  parcours(3) have revealed to be so fun and thrilling that the name come by itself
 
  '''''LILO - LOWI - Adrenaline'''''
  <big><big>'''''Rendez-vous at the Start !'''''</big></big>
  [[File:Small-fgfs-20200521095013.png|2048x1022|none|START]]

  1) Tortoise oscillations - Succession of quick oscillations where the plane will
                              become quickly impossible to control and almost ever
                              resulting in a crash
  2) "Firewall! Firewall!  - Instruction/information given by one pilot to the other
                              where the thrust lever  is  beaten at the physical edge,
                              resulting  in  engines delivering  the absolute maximum
                              thrust power !
                              It is an extreme evasive maneuver that should only last
                              a few seconds. (about 6 ~ 8 for most engines).
                              It is one step beyond then the  "unleash  the  beast" !
                              Engines must come back to normal thrust levels in order
                              to avoid irreversible damages.
  3) parcours              - french word for track, journey, route, course and even
                              of a new urban sport.
