This article is about starting up the engine manually. By default the engines are already running when entering the helicopter, so you don't have to startup the engines yourself.<br />
<br />
== Enable manual startup feature ==<br />
To make the helicopter start with engines off, so that you have to start them yourself you have to change a value in [[eech.ini]].<br />
#Open [[eech.ini]]<br />
#:Path: <code>...\Razorworks\cohokum\eech.ini</code><br />
#Search for: <code>enginestartup=</code><font color="blue">x</font><br />
#: Where <font color="blue">x</font> can be <code>0</code> (off) or <code>1</code> (on).<br />
#Change it to: <code>enginestartup=1</code><br />
#Save eech.ini.<br />
#(Re)start the game<br />
<br />
== Powering up avionics ==<br />
<br />
Before you can start the engines you have to power up the [http://en.wikipedia.org/wiki/Avionics avionics] so that you can see what's happening.<br />

== About MFDs ==<br />
The Comanche's engine screen is shown on the <u>outer</u> left MFD screen, but this is not as integral as it is shown on the main left MFD.<br />
<br />
Note that '''Secondary Power Unit (SPU)''' is also referred to as the '''Auxiliary Power Unit (APU)'''.<br />

== Start up sequence ==<br />
#Press <code>CTRL</code> + <code>[</code> to put the engine screen on the '''left''' MFD-screen. [[image:startup 1.png|none|frame|The engine MFD before any input.]]<br />
# Press <code>CTRL</code> + <code>/</code> to start up the <u>s</u>econdary <u>p</u>ower <u>u</u>nit (SPU). The SPU will reach 100%.[[image:startup 2.png|none|frame|The SPU (bottom right) at 100%.]]<br />
# Press <code>R</code> to disengage the rotor brakes. [[image:RTR-BRK.png|none|frame|The rotor brakes (left green light) still on.]]<br />
# Press <code>CTRL</code> + <code>,</code> to engage the left engine starter.[[image:startup 3.png|none|frame|The left engine running by the SPU.]]<br />
# When the left engine runs stable powered by the SPU (above 15% NG RPM). Ignite the engine by pressing <code>,</code> twice. The engine temperature will increase fast, and engine RPM will slowly increase.[[image:startup 4.png|none|frame|The left engine runs by it self, now.]]<br />
# The main rotor starts spinning once engine RPM is sufficient. [[image:startup 8.png|none|frame|The main rotor (center bar) at full speed.]]<br />
# Repeat step 3 and 4 for the right engine. Use <code>.</code> (instead of <code>,</code>) for the right engine.<br />
# When both engines run, the SPU will shut itself down. [[image:startup 5.png|none|frame|Now, both engines runs by themselves, and the SPU has shut down.]]<br />
# Press <code>,</code> and <code>.</code> simultaneously to throttle up both engines. Increase it until it hits the "fly" position.[[image:startup 6.png|none|frame|Throttle (bottom middle) at 40%.]][[image:startup 7.png|none|frame|Throttle in the fly position.]]<br />
# While the rotor is spinning up, close the canopy doors by pressing <code>ALT</code> + <code>C</code>.[[image:canopy.png|none|frame|The canopy doors are still open.]]<br />
# When the rotor RPM reaches 90%, the RPM caution light turns off.[[image:RPM.png|none|frame|The RPM light still on.]] [[image:RPM-off.png|none|frame|The RPM light is off.]]<br />
# Now, you are ready to take off. Increase collective to get airborne.[[image:startup 9.png|none|frame|The helicopter is airborne.]]<br />

#: <code>CTRL</code> + <code>/</code><br />
# Wait till the SPU will reaches 100%.<br />
# Engage the left engine starter.<br />
#: <code>CTRL</code> + <code>,</code><br />
# Ignite the engine (when the left engine RPM is above 15%).<br />
#: <code>,</code> (press twice)<br />
# Repeat the 2 previous steps for the right engine.<br />
