Le C 172 est l'avion par défaut dans FlightGear depuis 2000, il a remplacé le Navion. Il a eu un long développement et il inclut une grande variété de fonctionnalités pour FlightGear. Voir [[Understanding Propeller Torque and P-Factor|comprendre les effets moteur]].
Le C 172 est l'avion par défaut dans [[FlightGear]] depuis 2000, il a remplacé le [[Navion]]. Il a eu un long développement et il inclut une grande variété de fonctionnalités pour FlightGear. En 2015, il a été complètement rénové ; cela comprend  de nouvelles options de moteur, de taille de pneus ou de flotteurs, ainsi qu'une refonte complète du cockpit. Cette nouvelle version détaillée de l'avion est devenu l'avion inclus en standard depuis [[Changelog_3.6|FlightGear 3.6]].
 
== Contenu et variantes ==
 
The new C172p has a much better 3D model and is now fully textured (including the interior). All the switches in the cockpit are clickable. It also has an improved FDM, more complex procedures and new realistic checklists, new sound effects, and damage modelling. The aircraft can get damaged if mishandled (e.g. gear collapse after a hard landing).
 
[[File:C172p-bodensee-panorama.jpg|center|800px]]
 
The aircraft currently has five variants, all available from the aircraft menu:
* regular wheels
* 26" bush tires
* 31" bush tires
* pontoons
* amphibian
* snow skis
 
Also, from the same menu, the user can select two different engines:
* 160 HP
* 180 HP (recommended when using pontoons, amphibian and skis variants)
 
The aircraft now can get damaged from collisions, crashes, hard landings or overload while in-flight, and the modelling includes wheel collapse, wings breaking, etc. The damage can be turned off in the aircraft menu, which also contains an option for repairing the aircraft.
 
The windows now can get foggy or frosty, depending on the combination of interior and exterior temperatures. The pilot must then use the Cabin Heat and Cabin Air levers (on the right of the flaps) to control it. Alternatively, it's possible to disable the effect in the "Aircraft Options" in the "Cessna 172P" menu. This effect depends on the new ALS effects found in 3.5 and above, and will also have the side effect of producing grey windows in versions prior to 3.5.
 
The FDM has also been modified. The aircraft may enter into a spin in case of an asymmetric stall (a particularly dangerous situation when turning to final, in which case the aircraft is at low speed and low height). The FDM has also been tweaked to include hydrodynamics effects while taking off or landing on water, as well as adding a new 180 HP engine.
 
There are several liveries available, some of which have higher resolution than others, which are marked as HD in the liveries menu. Each of the HD liveries also has unique cockpit and interior textures.

== Variantes ==
Also, if the user has enabled ALS (Atmospheric light scattering) in the Rendering Options, then it's possible to activate the flashlight by clicking on the "Cessna 172P" menu and selecting "Flashlight". Select it once for the white flashlight, select it again for a red one and select it one more time to turn it off.

'''Extérieur:'''
== FAQ ==
* textures / le mapping a besoin de quelques corrections
 
Here are some of the frequently asked questions about this aircraft:
 
 
'''Q:''' I am experiencing grey windows, what is happening?
 
'''A:''' If you experience grey windows, you do not have the correct FlightGear version. This aircraft requires 3.5 or above.
 
 
'''Q:''' Why does the aircraft keep turning left?
 
'''A:''' Please see [[understanding Propeller Torque and P-Factor]]. If using the amphibian model on a solid runway, note that at the taxiing is done by differential braking (the rudder becomes more and more effective as the plane gains speed).
 
 
'''Q:''' Why will the engine not start?
 
'''A:''' You can start the engine automatically by clicking on the menu "Cessna C172P", selecting "Autostart" and then simply holding the key {{Key press|S}}. For a manual start, please follow the checklists available by clicking on the menu "Help" followed by "Aircraft Checklists". As seen above, the engine must by "primed" before starting. If oil management is activated, you must have enough oil for the engine to work (more than 5.0 quarts). If fuel contamination is activated, the fuel must be light blue in order for the engine to properly work.
 
 
'''Q:''' Why does the engine die immediately after startup?
 
'''A:''' Probably because the throttle is being incremented too fast after startup as the engine needs a few seconds to stabilize itself.
 
 
'''Q:''' Why can't I start the sim with the engine running?
 
'''A:''' You can! Go to the menu "Cessna C172P", select "Aircraft Options" and tick the option "Start with engine running".
 
 
'''Q:''' Why the aircraft doesn't move?
 
'''A:''' The aircraft won't move if you have the parking brakes set, or if either of the wing tie-downs, the tail tie-down or wheel chocks are in place (if the option "allow securing aircraft" is enabled in the aircraft menu).
 
 
'''Q:''' Why the airspeed indicator doesn't work?
 
'''A:''' If the option "allow securing aircraft" is enabled in the aircraft menu, then very likely you forgot to remove the pitot tube cover.
 
 
'''Q:''' How can I switch to the bush tires/pontoons/amphibian?


'''Cockpit 3D:'''
'''A:''' By clicking in menu "Cessna 172P", selecting "Aircraft Options" and then selecting the other landing gear options.
* Le cockpit est texturé mais les textures peuvent être améliorées
* Il manque un pilote et un copilote
* Les étiquettes des interrupteurs pour les lumières sont difficiles à lire


'''Général:'''
* On atteint souvent des vitesses de 135 kt indiqués à 2850 tr/min en pallier à 1000 ft AMSL, en consommant seulement 13 gallons/heure. Ce n'est pas le genre de performances observées sur de vrais Skyhawk.
** Quelles sont les performances attendues d'après vos estimations?

'''Q:''' How can I switch to the 180 HP engine?
=== Listes ===
* [[Aircraft]]
* [[Aircraft Todo]]
* [[FlightGear 1.0 default aircraft]]


=== Liens ===
'''A:''' This is also done by clicking in menu "Cessna 172P", selecting "Aircraft Options" and then selecting the engine power option.
 
 
'''Q:''' Why can't I take off from the water without crashing the plane?
 
'''A:''' Taking off and landing on water can be quite tricky. Try applying a little bit of back pressure on the yoke while accelerating to 55 KIAS. It's also recommended to use the 180 HP engine instead of the default 160 HP, as the extra weight of the pontoons make it really hard to climb with the default engine.
 
 
'''Q:''' Why is the simulator lagging so much?
 
'''A:''' As with any complex 3D model, this new version of the c172p is a bit more demanding on the computers than the older one. If you are having troubles with performance, try using non-HD liveries which use textures with lower resolutions, as well as other solutions that can improve performance (disabling certain graphical options in the Rendering Options, lowering the resolution of FlightGear, etc.).
 
Some tricks that help to increase fps is by disabling all GUI windows, including the menu bar and the orange fps counters at the bottom of the screen. You can display an alternative fps counter in the top left corner via the "Debug" menu and then selecting "Cycle On-Screen Statistics". Make sure to hide the menu bar by pressing F10 to see the counter.
 
A second trick is to simply disable the rendering of all clouds if you don't mind. Start FlightGear with "--prop:/sim/rendering/draw-mask/clouds=0".
 
If you notice heavy slowdowns when flying over certain scenery and you see FlightGear generating many "Warning:: Picked up error in TriangleIntersect" messages in the terminal or log file, you can disable this by starting FlightGear with "--prop:/sim/rendering/osg-notify-level=fatal".
 
 
'''Q:''' Why are the windows getting foggy/frosty?
 
'''A:''' If the dew point of the cabin air temperature is higher than the surface temperature of the windshield, the windows will get either foggy or frosty. Use the Cabin Heat and Cabin Air levers (on the right of the flaps) to control it. The dew point rises with the temperature in the cabin, and it rises faster than the windshield temperature can adjust, resulting in temporary fog. If the air is very humid, the dew point is going to be very close to the cabin temperature, which makes it likely that it will be higher than the windshield temperature. Extra passengers will create a more humid atmosphere in the cabin. Try to increase air flow using the Cabin Air lever or overhead air vents in order to decrease the humidity or temperature. Alternatively, disable the effect by going to the menu "Cessna 172P", selecting "Aircraft Options" and disable the option "Enable frost and fog".
 
 
'''Q:''' How do I increase the cabin air temperature?
 
'''A:''' Increase the cabin air temperature by opening the Cabin Heat lever. In order to actually get a heated air flow, you need a medium or high EGT (Exhaust Gas Temperature -- the instrument between the yoke and the ADF instrument), and airspeed and/or sufficient propeller RPM.
 
 
'''Q:''' How can I click on a switch which is being covered by the yoke?
 
'''A:''' You can hide the yokes by clicking on them or by going to the menu "Cessna 172P", selecting "Hide/Show Yokes".
 
== Development status/Issues/TODO ==
 
This aircraft is undergoing a constant development, which can be followed on its [https://github.com/Juanvvc/c172p-detailed repository], where a [https://github.com/Juanvvc/c172p-detailed/issues list of issues and future enhancements] can also be found.

Le Cessna 172 Skyhawk est un avion quadriplace, monomoteur à aile haute. Il effectua son premier vol en 1955 et est toujours en production, plus de Cessna 172 ont été construits que tout autres avions.

Le C 172 est l'avion par défaut dans FlightGear depuis 2000, il a remplacé le Navion. Il a eu un long développement et il inclut une grande variété de fonctionnalités pour FlightGear. En 2015, il a été complètement rénové ; cela comprend de nouvelles options de moteur, de taille de pneus ou de flotteurs, ainsi qu'une refonte complète du cockpit. Cette nouvelle version détaillée de l'avion est devenu l'avion inclus en standard depuis FlightGear 3.6.

Contenu et variantes

The new C172p has a much better 3D model and is now fully textured (including the interior). All the switches in the cockpit are clickable. It also has an improved FDM, more complex procedures and new realistic checklists, new sound effects, and damage modelling. The aircraft can get damaged if mishandled (e.g. gear collapse after a hard landing).

  • pontoons
  • amphibian
  • snow skis

Also, from the same menu, the user can select two different engines:

The aircraft now can get damaged from collisions, crashes, hard landings or overload while in-flight, and the modelling includes wheel collapse, wings breaking, etc. The damage can be turned off in the aircraft menu, which also contains an option for repairing the aircraft.

The windows now can get foggy or frosty, depending on the combination of interior and exterior temperatures. The pilot must then use the Cabin Heat and Cabin Air levers (on the right of the flaps) to control it. Alternatively, it's possible to disable the effect in the "Aircraft Options" in the "Cessna 172P" menu. This effect depends on the new ALS effects found in 3.5 and above, and will also have the side effect of producing grey windows in versions prior to 3.5.

The FDM has also been modified. The aircraft may enter into a spin in case of an asymmetric stall (a particularly dangerous situation when turning to final, in which case the aircraft is at low speed and low height). The FDM has also been tweaked to include hydrodynamics effects while taking off or landing on water, as well as adding a new 180 HP engine.

There are several liveries available, some of which have higher resolution than others, which are marked as HD in the liveries menu. Each of the HD liveries also has unique cockpit and interior textures.

The aircraft has a simulation of the Bendix/King KAP140 Autopilot.

Also, if the user has enabled ALS (Atmospheric light scattering) in the Rendering Options, then it's possible to activate the flashlight by clicking on the "Cessna 172P" menu and selecting "Flashlight". Select it once for the white flashlight, select it again for a red one and select it one more time to turn it off.

The aircraft can now go through a pre-flight: wheel chocks, tie-downs and the pitot tube cover can now be added or removed, oil management and fuel contamination by water have been implemented (both of which are not activated by default, but are available in the aircraft menu).

A: If the dew point of the cabin air temperature is higher than the surface temperature of the windshield, the windows will get either foggy or frosty. Use the Cabin Heat and Cabin Air levers (on the right of the flaps) to control it. The dew point rises with the temperature in the cabin, and it rises faster than the windshield temperature can adjust, resulting in temporary fog. If the air is very humid, the dew point is going to be very close to the cabin temperature, which makes it likely that it will be higher than the windshield temperature. Extra passengers will create a more humid atmosphere in the cabin. Try to increase air flow using the Cabin Air lever or overhead air vents in order to decrease the humidity or temperature. Alternatively, disable the effect by going to the menu "Cessna 172P", selecting "Aircraft Options" and disable the option "Enable frost and fog".


Q: How do I increase the cabin air temperature?

A: Increase the cabin air temperature by opening the Cabin Heat lever. In order to actually get a heated air flow, you need a medium or high EGT (Exhaust Gas Temperature -- the instrument between the yoke and the ADF instrument), and airspeed and/or sufficient propeller RPM.


Q: How can I click on a switch which is being covered by the yoke?

A: You can hide the yokes by clicking on them or by going to the menu "Cessna 172P", selecting "Hide/Show Yokes".
