LILO-LOWI-Adrenaline

LILO-LOWI-Adrenaline

Climb from "Corna" to "Liscidini"

Clock Around Santa Giustina Lake

3/4 Clock Around "Santa Giustina Lake"

  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 ...
  
  Excursion at Paro (Buthan) 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)
  
  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.
  
  Landing - Explanation help - 2
  
  The plane accumulate energy during the descent. When he touch the ground, 
  this energy tend to push the plane lower then the ground !
  
  Gear shock absorbers will try to absorbing this excess of energy.
  But, what if this energy is stronger then the gear shock absorber ?
  
  Landing - Explanation Help - 6
  
  Case 1. - The shock absorber and or the landing gear crash. 
            You have a belly landing.
  
  Case 2. - The shock absorber release so many energy that plane start bumping
            As soon as you have cognition of the bump up - do not hesitate :
            - Firewall ! Firewall ! (2)
            - Go Around !
            - Detente.
            You are going to be known as Captain Kangourou for the rest of 
            the times, but your passengers, your crew, you plane and you, are 
            going to be safe.
  
  A quite equivalent disastrous result will be caused by a too high stall.
  
  Landing - Explanation Help - 5
  
  The plane stall from an height that still demand too much absorption by the shock 
  absorber, resulting in a more hazardous belly landing.


  The Proper way
  Exhaust the descent energy before to touch ground.
  
  About this, Rob wrote :
  ---------------------
  "This energy that in the air is your friend and keep you alive, on the ground become
  you enemy".
  "You can not just leave it there. You have accumulated it - you have to exhaust it !"
  
  Landing - Explanation Help - 3
  
  Only then you become able to land ...and by landing i do mean, able to brake, steer 
  and control your plane on land !
  
  So, which is the proper height to induce the stall ?
  
  "Any height that can be handled by the landing gear shock absorber."
  "But, ideally, from 'Zero' feet above RWY."
  
  Landing - Explanation Help - 4   
  
  Thank you Rob.
  A new approach
  So, I was failing to have proper landings because  I was looking for a solution  in
  the average of the flying conditions whereas it was at the extreme edge, where  the
  plane start to stall.
  
  And this, for me, have been game changing. 
  
  I have learned the only way to master my chosen plane was exploring its limits.
  How is "this" related with LILO-LOWI-Adrenaline and Fun ?
  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
  Rendez-vous at the Start !

  Have fun,

  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.
