== Development status/Issues/Todo ==
== Features ==


=== Outside ===
The new Cessna 182S has a very detailed 3D model and cockpit with highly detailed textured. Most of the switches in the cockpit are clickable. It has a very realistic FDM.
;Cockpit instruments can be seen through the aileron
: This is presumably not aircraft-specific;  see the Z-buffer burn-through item on the  project-wide [[Bugs]] page.
; aircraft has no shadow
; <strike>The model has no landing light</strike> (See below)
: This detracts only slightly from the realism of the landing, because at touchdown attitude, the pitch attitude is so high  that the landing light is pointing way up in the air;  therefore almost anything that could possibly be lit up by the landing light  is blocked from view by the cowling.  A privately-owned aircraft is  not even required to have a landing light, even when being operated  at night.  Landing with burned-out landing  lights is no big deal ... assuming the runway-edge lights are working. The so-called landing light is mostly just a taxi  light.  The only part of the landing where the landing light is  really useful is for reading the big painted number on the runway,  to confirm that you aren't landing on the wrong runway.


=== Cockpit ===
[[File:c182-panel-detail.jpg|center|800px]]
; No outside-air-temperature gauge.
: There are empty spots for extra gauges, should be easy.
; The 2D cockpit instruments are visible through the 3D yoke.
: This is another example of "burn through".
; Can't hear sound when pressing the switches and levers in the cockpit.
; No rudder trim control or indicator.


=== General ===
There are currently five liveries available: default Cessna livery, D-ELFP, HB-CZV, N182PJ and N321HW.
; The model doesn't implement cowl flaps.
: This  affects the realism, especially if you are using the model for  "transition training" into complex aircraft.  Cowl flaps are part of  the workload that makes the thing complex.  Also they underline the  point that the checklist that works for one aircraft doesn't necessarily work for them all.
; Oil pressure problems.
: In the model, after flying for a while, the oil  pressure falls below the bottom of the green.  Not by a lot, but  definitely outside the green range, and therefore outside the normal  range.  Is this perhaps because somebody forgot to open the cowl  flaps?  This detracts from the realism;  most pilots would be very unhappy  flying an aircraft with out-of-normal oil pressure.
; Unrealistic adverse yaw.
: In cruise, the model has much more adverse yaw than a real Skylane. The real thing has differential aileron deflection  which the designers have lovingly tuned so that you can cruise with  your feet on the floor (not on the pedals). At low airspeeds, of course, the real aircraft still has plenty of  adverse yaw.
; Unrealistic damping, or lack thereof.
: Compared to the real aircraft, the model seems to have  not enough yaw-wise damping and not enough roll-wise damping. (Taken together these imply not enough damping of the Dutch roll  mode, but this is a corollary, not a separate issue.)  Roughly  speaking, this creates the impression that the model is harder to  handle than the real aircraft.
; Engine sound in cockpit does not differ from outside engine sound.
; Bad "reset" behavior.
: Aircraft is sometimes flipped when pressing the reset button.
: Aircraft has the wrong elevation (approximately 20 meter above the runway) after pressing the reset key
; Flaps/power/trim interaction.
: The C182 model does not realistically capture the flap/power/trim interaction. In the model, extending the flaps seems to cause a nose-down pitching moment, which is the wrong direction.  And the power-dependence of the effect is not realistically modelled.  In a real C182 / C172 / C152 / C150, the flap/trim interaction can be described as follows:
:* Changing the flap setting has little effect when the engine is at idle.
:* Changing the power setting has little effect when the flaps are in the retracted position.
:*  However, there is a multiplicative effect: Adding power causes a nose-up pitching moment when flaps are in an extended position. Or, to say the same thing, extending the flaps causes a nose-up pitching moment. The effect is in proportion to the amount of power being developed *times* the amount of flap deflection.


; Unrealistic brake noise.
The aircraft has a simulation of the [[Bendix/King KAP140 Autopilot]]. The cockpit can be illuminated at night using two knobs. These knobs have two modes each, which can be used by clicking and dragging horizontally or vertically.
 
Also, if the user has enabled ALS (Atmospheric light scattering) in the Rendering Options, some effects activated such as cockpit shadows, visible landing lights from the cockpit, rain effect on the windshield.
 
The Cessna 182S comes have static objects which can be activated via the Ground Equipment dialog in the aircraft menu. These include a fuel tan trailer, ladders to access the fuel caps (and which the walker can climb!) and a ground power unit. The aircraft can also go through a pre-flight check: wheel chocks, tie-downs and the pitot tube cover can now be added or removed. Security cones are also available.

== Handling The Aircraft ==
 
=== Pre-Flight Inspection ===
[[File:C182-ready-for-take-off.jpg|270px||thumb|Cessna 182S ready for take off]]
It's recommended to use any exterior view or activate the walker for these procedures.
* Check fuel quantity on both tanks
* Left wing: remove pitot tube cover
* Left wing: remove tie-down
* Tail: remove tie-down
* Right wing: remove tie-down
* Nose: remove wheel chocks
 
=== Engine Start (manual and complex startup) ===
* Mixture: Rich
* Propeller: High RPM
* Throttle: Open 1/8
* Parking Brake: Applied ({{Key press|Shift|B}})
* Prop Area: Clear
* Master switch: ON (both)
* Auxiliary Fuel Pump Switch: ON
* Magnetos: Both (Press {{Key press|<nowiki>}</nowiki>}} three times)
* Ignition: Start ({{Key press|S}})
 
=== Takeoff ===
* no flaps
* full throttle
* rotate at 55 KIAS
 
=== Climbout ===
* no flaps
* full throttle
* 80 KIAS
 
=== Cruise ===
[[File:c182-default.jpg|270px||thumb|Cessna 182S in the air]]
* 2000-2400 RPM
* mixture rich of peak
* speed between 120-140 knots depending on the power settings
 
=== Landing ===
* full flaps
* 60-70 KIAS
 
=== Airspeeds ===

== Development status/Issues/TODO ==
 
This aircraft is undergoing a constant development, which can be followed on its [https://github.com/HHS81/c182 repository], where a [https://github.com/HHS81/c182/issues list of issues and future enhancements] can also be found.
