 __TOC__
 This template has provisions for four sections: General characteristics, performance, armament, and avionics.  What follows is list of the parametres that appear in each section, and specialised instructions for their use where necessary.
 
 Most numerical quantities are divided into 'main' and 'alt'.  For example, the quantity 'empty weight' is specified by the parametres {{{emtpy weight main}}} and {{{empty weight alt}}}.  For a U.S. aircraft, which are measured using the [[Imperial unit|Imperial System of units]], the value for 'main' would be given in pounds (lb), and the value for 'alt' in kilograms (kg).  Most other aircraft are measured using the [[Metric system]], so they will have kg for 'main' and lb for 'alt'.
 
 Because of the [[m:ParserFunctions|ParserFunctions]] this template uses, all values will automatically appear in the article once they have been specified.  For example, if I specify &lt;code&gt;|area main=1,000 ft²|area alt=93 m²&lt;/code&gt;, the text
 * '''Wing area:''' 1,000 ft² (93 m²)
 will automatically appear in the article.
 
 In the following instructions, parametres are referred to thus: {{{parametre name}}}.  When indicating which values should be entered for each parametre, the notation &lt;code&gt;|parametre name=vale&lt;/code&gt; will be used.
 
 ==Non-specifications parametres==
 The template uses three paramtres that are not directly related to the specs: {{{plane or copter?}}}, {{{jet or prop?}}}, and {{{ref}}}.  The first two control template output; the last one provides citation information.
 ;{{{plane or copter?}}}:If the aircraft is a rotorcraft (including helicopters, gyrodynes, tiltrotors, etc.), the value for this parametre should be &lt;code&gt;|plane or copter?=copter&lt;/code&gt;.  If it is a fixed wing aircraft, the value should be specified as &lt;code&gt;|plane or copter?=plane&lt;/code&gt;.
 ;{{{jet or prop?}}}:For planes that are powered by jet engines or rockets, specify &lt;code&gt;|jet or prop?=jet&lt;/code&gt;. For those powered by propellers, specify &lt;code&gt;|jet or prop?=prop&lt;/code&gt;.  Occasionally, aircraft have both jet engines and propellers; for these, specify &lt;code&gt;|jet or prop?=both&lt;/code&gt;.  Unpowered aircraft such as gliders should be denoted by &lt;code&gt;|jet or prop?=neither&lt;/code&gt;.
 ;{{{ref}}}:Used to cite the sources for the specifications section.  Example: &lt;code&gt;&lt;nowiki&gt;|ref=The Encyclopedia of World Aircraft&amp;lt;ref&gt;{{cite encyclopedia|last=Donald|first=David|year=1997|title=Boeing Model 299 (B-17 Flying Fortress|encyclopedia=The Encyclopedia of World Aircraft: 1|location=Etobicoke, Ontario, Canada|publisher=Prospero Books|id=ISBN 1-85605-375-X|pages=pages 154-155}}&lt;/ref&gt;&lt;/nowiki&gt;&lt;/code&gt;.  See [[Wikipedia:Citation templates]] for information on the citation templates available and how to use them.
 
 ==General characteristics==
 ;{{{crew}}}:The number of people required to operate the aircraft.  If you wish to specify the roles played by each crew member, do so in something similar to the following format: &lt;code&gt;|crew=3 (pilot, copilot, flight engineer)&lt;/code&gt;
 ;{{{capacity}}}:The number of passengers the aircraft can carry.  For civilian passenger aircraft, this should usually be specified &lt;var&gt;x&lt;/var&gt; number of passengers: &lt;code&gt;|capacity=88 passengers&lt;/code&gt;.  Most military transports can be used for patients.  In this case, something similar to the system used for the C-130 Hercules may be in order:
 &lt;pre&gt;|capacity=&lt;br/&gt;
 ** 92 passengers ''or''
 ** 64 airborne troops ''or''
 ** 74 litter patients with 2 medical personnel
 &lt;/pre&gt;
 ;{{{payload main}}}, {{{payload alt}}}, {{{payload more}}}:Specifies the amount of cargo that can be carried by an aircraft.  For 'main' and 'alt', specify the weight of the payload.  If applicable, use {{{payload more|}}} to specify the type of payload usually carried, such as fertiliser for agricultural aircraft or mail for mailplanes.
 ;{{{length main}}}, {{{length alt}}}:The length of the aircraft from nose to tail.  For helicopters, this means the length of the fuselage without taking the rotor into consideration.
 ;{{{span main}}}, {{{span alt}}}:The wingspan of fixed wing aircraft, or the main rotor diameter for rotorcraft.
 ;{{{height main}}}, {{{height alt}}}
 ;{{{area main}}}, {{{area alt}}}:The area of the wing of a fixed wing aircraft, or the total area of all main rotors for rotorcraft (does not include maneuvering rotors).
 ;{{{airfoil}}}:For fixed wing aircraft, the type of airfoil the wing uses. Eg, see [[NACA airfoil]] for information on airfoil types.
 ;{{{empty weight main}}}, {{{empty weight alt}}}:The weight of the aircraft when unloaded—no crew, passengers, cargo, or fuel.
 ;{{{loaded weight main}}}, {{{loaded weight alt}}}:The weight of the aircraft when loaded for a 'typical' mission.  This statistic is cited for almost any aircraft, but it is relatively arbitrary, so only use statistics given in sources.
 ;{{{useful load main}}}, {{{useful load alt}}}:The difference between the aircraft's maximum weight and empty weight.
 ;{{{max takeoff weight main}}}, {{{max takeoff weight alt}}}, {{{max takeoff weight more}}}:The heaviest the aircraft can be and still get off the ground.
 ;{{{more general}}}: A place to put anything relevant not included already under the general parameters eg &quot;Fuel Capacity: 500 gallons&quot;
 
 ==Engines==
 If there is any information that needs to be added after the engine specs, it should be added using the parameter {{{more general}}}.
 
 ===Propellers===
 ;{{{number of props}}}:The number of engines that drive the propellers.  For fixed wing aircraft, this is usually—but not always—the same as the number of propellers.
 ;{{{engine (prop)}}}:The model of engine the aircraft uses.  Example: &lt;code&gt;&lt;nowiki&gt;|engine (prop)=[[Pratt &amp; Whitney R-4360]]-53 &quot;Wasp Major&quot;&lt;/nowiki&gt;&lt;/code&gt;.
 ;{{{type of prop}}}:The configuration of the engine.  Examples: &lt;code&gt;&lt;nowiki&gt;|type of prop=liquid-cooled [[V12 engine]]&lt;/nowiki&gt;&lt;/code&gt;, &lt;code&gt;&lt;nowiki&gt;|type of prop=[[turboprop]]&lt;/nowiki&gt;&lt;/code&gt;, &lt;code&gt;&lt;nowiki&gt;|type of prop=[[radial engine]]&lt;/nowiki&gt;&lt;/code&gt;.
 ;{{{power main}}}, ({{{power alt}}}):The power output of the engine.
 ;{{{power original}}}:For some engines the power output may have been originally measured in an unconventional unit.  For example, older German engines originally had their power measured in [[Pferdestärke]] (PS).  Sample usage of this parametre: &lt;code&gt;&lt;nowiki&gt;|power original=&lt;ref&gt;Originally measured as 15,000 [[Pferdestärke|PS]].&lt;/nowiki&gt;&lt;/code&gt;
 ;{{{power more}}}:More information on the power rating, such as the rpm of the engine.
 
 ===Jets===
 ;{{{number of jets}}}:The number of jet engines or rockets the aircraft has.
 ;{{{engine (jet)}}}:The model of jet or rocket used by the aircraft
 ;{{{type of jet}}}:The configuration of jet, such as [[turbojet]], [[turbofan]], [[thermojet]], [[rocket]], etc.
 ;{{{afterburning thrust main}}}, {{{afterburning thrust alt}}}:Thrust of the engine with afterburner, if applicable.
 ;{{{thrust main}}}, {{{thrust alt}}}:The thrust of the engine; if the engine has afterburners, this parametre denotes dry thrust.
 ;{{{afterburning thrust original}}}, {{{thrust original}}}:Some engines had their original measurements taken in unconventional units.  For example, many Russian and Soviet engines were originally rated using [[kilogram-force]].
 
 ===Propeller model and configuration===
 ;{{{propeller or rotor?}}}:If it is a propeller on a fixed wing aircraft, specify &lt;code&gt;|propeller or rotor?=propeller&lt;/code&gt;.  If it is a rotor on a helicopter or other rotary wing aircraft, specify &lt;code&gt;|propeller or rotor=rotor&lt;/code&gt;.
 ;{{{propellers}}}:The model and configuration of the propellers.  Example: &lt;code&gt;&lt;nowiki&gt;|propellers=Three-bladed [[Hamilton Standard]]&lt;/nowiki&gt;&lt;/code&gt;.
 ;{{{number of propellers per engine}}}:With some aircraft, multiple propellers will be driven off one engine.  Use this parametre to specify the number per engine.
 ;{{{propeller diameter main}}}, {{{propeller diameter alt}}}:Used to indicate the diameter of the propellers.  For helicopters, the rotor diameter was already specified using the {{{span}}} parameter.
