|
| |
| We all have been at that point, is it not ?
| |
|
| |
| At the beginning, each one of us have struggled with our plane.
| |
|
| |
| The same has been true to design the LILO-LOWI-Adrenaline track and the challenges.
| |
| The writing of this article just had his own missed approaches.
| |
|
| |
| Landing ... We all did manage to bring the plane back on the ground ...
| |
|
| |
| 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 in this, and it is where Rob's
| |
| explanation earn a strong point !
| |
|
| |
|
| '''Landing is not <big><big>continuing</big></big> to descend until the ground - it is like a <big><big>controlled stall</big></big>.'''<small><small><ref>[ This is not an advice to seek real stall in real life.<br />Stall is a dynamic and complex situation, with pre-stall, deep-stall, several stall types (mainly 3), accelerated non-accelerated, and way more...<br />In RL, the reference you should follow, is your instructor.<br />Here the invitation is : in this simulator - training opportunity, let's go gaining experience on the edge, where the stall(s) lives.<br />A friend of mine after reading this got very sick, with red and black dots in the face and went sleepless... (kidding)<br />Please just do not drag me in pointless fights about "the right words" on this matter !

| |
|
| My 1st reaction was : "...no... no ways !"
| |
|
| |
| But the doubt got quickly away !
| |
|
| |
| Figure out a little motorboat changing direction :

| |
|
| |
| 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.<ref>[ Tortoise oscillations - Succession of quick oscillations where the plane will
| |
| become quickly impossible to control and almost ever
| |
| resulting in a crash. ]</ref>

|
| |
| If this happen, FIREWALL! and Go Around !<ref>[ "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. ]</ref>
| |
| 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.

|
| 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...
| |
|
| |
|
| <big><big>'''So, what is the "proper height" to stall ?'''</big></big>
| |
|
| |
|
| "Any height that can be handled by the landing
| |
| gear shock absorber."
| |
| "But, ideally, from 'Zero' feet above RWY."
| |

| The butter landing !
| |
|
| |
|
| <big><big><big>'''''Conclusion'''''</big></big></big>
| |
|
| |
|
| Stall '''''is''''' at the "edge" of the "flying envelope", '''''not''''' in the middle of the safe average.
| |
|
| |
| 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 <big>Rendez-vous</big> !'''''

| Does theses names from the real life are known to you ? :
| |
|
| |
| Robert (Bob) Pearson, Tadeusz Wrona, Jerzy Szwarc, Chesley Sullenberger,
| |
| Jeffrey Skiles, Carlos Dardano and Dionisio Lopez.
| |
|
| |
| They should !
| |
|
| |
| These are all heroes where with their outstanding pilot skills they have saved
| |
| lives !
| |
|
| |
| - "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) ;
| |
|
| |
| There are of course several more of them.
| |
|
| |
| But what all off them have in common, is the countless hours of flight in small
| |
| plane with the habit to take their small plane at the edge !
