href="getstart.html#QQ2-10-43" name="x10-430005">In-flight: All about instruments, keystrokes and menus</a></h2>
<!--l. 32--><p class="noindent">The following is a description of the main systems for controlling the program and
piloting the plane: Historically, keyboard controls<a
name="dx10-43001"></a> were developed first, and you can still
control most of the simulator via the keyboard alone. Later on, they were supplemented
by several menu entries, making the interface more accessible, particularly for beginners,
and providing additional functionality.
<!--l. 38--><p class="indent"> For getting a real feeling of flight, you should definitely consider getting a joystick<a
name="dx10-43002"></a> or
- preferred - a yoke<a
name="dx10-43003"></a> plus rudder pedals<a
name="dx10-43004"></a>. In any case, you can specify your device of
choice for control via the <span
class="pcrr7t---109">--control-mode </span>option, i.e. select joystick, keyboard<a
name="dx10-43005"></a>,
mouse<a
name="dx10-43006"></a>. The default setting is joystick. Concerning instruments, there are again two
alternatives: You can use the panel or the HUD.

href="getstart.html#QQ2-10-44" name="x10-440005.1">Starting the engine</a></h3>
<a
name="dx10-44001"></a>
<!--l. 57--><p class="noindent">Depending on your situation, when you start the simulator the engine<a
name="dx10-44002"></a>s may be on or off.
When they are on you just can go on with the start. When they are off, you have to start
them first. The ignition switch<a
name="dx10-44003"></a> for starting the engine is situated in the lower left corner
of the panel. It is shown in Fig. 4.
<!--l. 62--><p class="indent"> <div align="center"
class="centerline"><img
src="getstart5x.gif" alt="" class="fbox" > </div>
<!--l. 65--><p class="noindent">Fig. 4: <span
class="ptmri7t---109">The ignition switch.</span>
<!--l. 69--><p class="indent"> It has five positions: &#8221;OFF&#8221;, &#8221;L&#8221;, &#8221;R&#8221;, &#8221;BOTH&#8221;, and &#8221;START&#8221;. The extreme right
position is for starting the engine. For starting the engine, put it onto the position
&#8221;BOTH&#8221; using the mouse first.
<!--l. 71--><p class="indent"> Keep in mind that the mixture lever<a
name="dx10-44004"></a> has to be at 100 % (all the way in) for starting
the engine - otherwise you will fail. In addition, advance the throttle<a
name="dx10-44005"></a> to about
25 %.
<!--l. 73--><p class="indent"> Operate the starter<a
name="dx10-44006"></a> using the SPACE key now. When pressing the SPACE key you
will observe the ignition switch to change to the position &#8221;START&#8221; and the engine to
start after a few seconds. Afterwards you can bring the throttle back to idle (all the way
out).
<!--l. 75--><p class="indent"> In addition, have a look if the parking brake<a
name="dx10-44007"></a>s are on (red field lit). If so, press the &#8221;B&#8221;
button to release them.
<h3 class="sectionHead"><span class="titlemark">5.2</span> <a

<a

<!--l. 81--><p class="noindent">While joystick<a
name="dx10-45002"></a>s or yoke<a
name="dx10-45003"></a>s are supported as are rudder<a
name="dx10-45004"></a> pedals, you can fly <span
class="ptmbi7t---109">FlightGear</span>
using the keyboard alone. For proper control of the plane during flight via the keyboard
(i) the <span
class="pcrr7t---109">NumLock</span><a
name="dx10-45005"></a> key must be switched on (ii) the <span
class="ptmbi7t---109">FlightGear </span>window must
have focus (if not, click with the mouse onto the graphics window). Several
of the keyboard controls might be helpful even in case you use a joystick or
yoke.
<!--l. 88--><p class="indent"> After activating <span

<!--l. 244--><p class="noindent">The Cessna instrument panel is activated by default when you start <span
class="ptmbi7t---109">FlightGear</span>, but can
be de-activated by pressing the &#8221;P&#8221; key. While a complete description of all the functions

<!--l. 249--><p class="indent"> All panel levers and knobs can be operated with the mouse To change a control,

<!--l. 257--><p class="noindent">Fig. 5: <span
class="ptmri7t---109">The panel.</span>
<!--l. 261--><p class="indent"> Let us start with the most important instruments any simulator pilot must know. In
the center of the instrument panel (Fig. 5), in the upper row, you will find the artificial
horizon<a
name="dx10-47003"></a> (attitude indicator<a
name="dx10-47004"></a>) displaying pitch<a
name="dx10-47005"></a> and bank<a
name="dx10-47006"></a> of your plane. It has pitch marks as
well as bank marks at 10, 20, 30, 60, and 90 degrees.
<!--l. 267--><p class="indent"> Left to the artificial horizon, you&#8217;ll see the airspeed indicator<a
name="dx10-47007"></a>. Not only does it
provide a speed indication in knots but also several arcs showing characteristic velocity
rages<a
name="dx10-47008"></a> you have to consider. At first, there is a green arc indicating the normal
operating range of speed with the flaps<a
name="dx10-47009"></a> fully retracted. The white arc indicates
the range of speed with flaps in action. The yellow arc shows a range, which
should only be used in smooth air. The upper end of it has a red radial indicating
the speed you must never exceeded - at least as long as you wan&#8217;t brake your
plane.
<!--l. 275--><p class="indent"> Below the airspeed indicator you can find the turn indicator<a
name="dx10-47010"></a>. The airplane in the
middle indicates the roll of your plane. If the left or right wing of the plane is aligned
with one of the marks, this would indicate a standard turn, i.e. a turn of 360 degrees in
exactly two minutes.
<!--l. 280--><p class="indent"> Below the plane, still in the turn indicator, is the inclinometer<a
name="dx10-47011"></a>. It indicates if rudder<a
name="dx10-47012"></a>
and aileron<a
name="dx10-47013"></a>s are coordinated. During turns, you always have to operate aileron<a
name="dx10-47014"></a> and rudder<a
name="dx10-47015"></a>
in such a way that the ball in the tube remains centered; otherwise the plane is skidding.
A simple rule says: &#8221;Step onto the ball&#8221;, i.e. step onto the left rudder pedal in case the
ball is on the l.h.s.
<!--l. 285--><p class="indent"> If you don&#8217;t have pedals or lack the experience to handle the proper ratio
between aileron/rudder automatically, you can start <span
class="ptmbi7t---109">FlightGear </span>with the option
<span
class="pcrr7t---109">--enable-auto-coordination</span>.<a
name="dx10-47016"></a>
<!--l. 289--><p class="indent"> To the r.h.s of the artificial horizon you will find the altimeter<a
name="dx10-47017"></a> showing the height
above sea level (not ground!) in hundreds of feet. Below the altimeter is the
vertical speed indicator<a
name="dx10-47018"></a> indicating the rate of climbing or sinking of your plane in
hundreds of feet per minute. While you may find it more convenient to use then
the altimeter in cases, keep in mind that its diplay usually has a certain lag in
time.
<!--l. 295--><p class="indent"> Further below the vertical speed indicator is the RPM (rotations per minute)
indicator<a
name="dx10-47019"></a>, which displays the rotations per minute in 100 RPMs. The green arc marks the
optimum region for long-time flight.
<!--l. 299--><p class="indent"> The group of the main instruments further includes the gyro compass<a
name="dx10-47020"></a> being situated
below the artificial horizon. Besides this one, there is a magnetic compass<a
name="dx10-47021"></a> sitting on top
of the panel.
<!--l. 303--><p class="indent"> Four of these gauges being arranged in the from of a &#8221;T&#8221; are of special importance:
The air speed indicator, the artificial horizon, the altimeter, and the compass should be
scanned regularly during flight.
<!--l. 307--><p class="indent"> Besides these, there are several supplementary instruments. To the very left you will
find the clock<a
name="dx10-47022"></a>, obviously being an important tool for instance for determining turn
rates.Below the clock there are several smaller gauges displaying the technical state of
your engine. Certainly the most important of them is the fuel indicator<a
name="dx10-47023"></a> - as any pilot
should know.
<!--l. 310--><p class="indent"> The ignition switch<a
name="dx10-47024"></a> is situated in the lower left corner of the panel (cf. Fig. 4). It
has five positions: &#8221;OFF&#8221;, &#8221;L&#8221;, &#8221;R&#8221;, &#8221;BOTH&#8221;, and &#8221;START&#8221;. The first one is
obvious. &#8221;L&#8221; and &#8221;R&#8221; do not refer to two engines (actually the Cessna does
only have one) but to two magnetos being present for safety purposes. The two
switch positions can be used for test puposes during preflight. During normal
flight the switch should point on &#8221;BOTH&#8221;. The extreme right position is for
<a
name="dx10-47025"></a>using a battery-powered starter<a
name="dx10-47026"></a> (to be operated with the SPACE key in flight
gear).
<!--l. 312--><p class="indent"> Like in most flight simulators, you actually get a bit more than in a real plane. The
red field directly below the gyro compass displays the state of the brakes<a
name="dx10-47027"></a>, i.e., it is lit in
case of the brakes being engaged. The instruments below indicate the position of
youryoke<a
name="dx10-47028"></a>. This serves as kind of a compensation for the missing forces you feel while
pushing a real yoke<a
name="dx10-47029"></a>. Three of the arrows correspond to the three axes of your yoke/pedal
controlling nose up/down, bank left/right, rudder left/right, and throttle. (Keep in mind:
They do <span
class="ptmb7t---109">not </span>reflect the actual position of the plane!) The left vertical arrow indicates
elevator trim.
<!--l. 314--><p class="indent"> The right hand side of the panel is occupied by the radio stack<a
name="dx10-47030"></a>. Here you find two
VOR<a
name="dx10-47031"></a> receivers (NAV),<a
name="dx10-47032"></a> an NDB<a
name="dx10-47033"></a> receiver (ADF<a
name="dx10-47034"></a>) and two communication radio<a
name="dx10-47035"></a>s
(COMM1/2)<a
name="dx10-47036"></a><a
name="dx10-47037"></a> as well as the autopilot.
<!--l. 319--><p class="indent"> The communication radio<a
name="dx10-47038"></a> is used for communication with air traffic facilities<a
name="dx10-47039"></a>; it is
just a usual radio transceiver working in a special frequency range. The frequency is
displayed in the &#8221;COMM&#8221; field. Usually there are two COM transceiver<a
name="dx10-47040"></a>s; this way you
can dial in the frequency of the next controller to contact while still being in contact with
the previous one.
<!--l. 325--><p class="indent"> The COM radio can be used to display ATIS<a
name="dx10-47041"></a> messages as well. For this purpose, just
to dial in the ATIS frequency of the relevant airport.
<!--l. 327--><p class="indent"> The VOR<a
name="dx10-47042"></a> (Very High Frequency Omni-Directional Range) receiver is used for course
guidance during flight. The frequency of the sender is displayed in the &#8221;NAV<a
name="dx10-47043"></a>&#8221; field. In a
sense, a VOR acts similarly to a light house permitting to display the position of the
aircraft on a radial around the sender. It transmits one omni-directional ray of radio
waves plus a second ray, the phase of which differs from the first one depending on its
direction (which may be envisaged as kind of a &#8221;rotating&#8221; signal). The phase difference
between the two signals allows evaluating the angle of the aircraft on a 360
degrees circle around the VOR sender, the so-called radial. This radial is then
displayed on the gauges NAV1 and NAV2, resp., left to frequency field. This way it
should be clear that the VOR dispaly, while indicating the position of the aircraft
relative to the VOR sender, does not say anything about the orientation of the
plane.
<!--l. 335--><p class="indent"> Below the two COM/NAV devices is an NDB<a
name="dx10-47044"></a> receiver called ADF (automatic
direction finder). Again there is a field displaying the frequency of the facility. The ADF
can be used for navigation, too, but contrary to the VOR does not show the
position of the plane in a radial relative to the sender but the direct heading from
the aircraft to the sender. This is displayed on the gauge below the two NAV
gauges.
<!--l. 341--><p class="indent"> Above the COMM1 display you will see three LEDs in the colors blue, amber, and
white indicating the outer, middle, and, inner, resp. marker beakon.<a
name="dx10-47045"></a><a
name="dx10-47046"></a><a
name="dx10-47047"></a> These show the
distance to the runway threshold during landing. They to not require the input of a
frequency.
<!--l. 346--><p class="indent"> Below the radios you will find the autopilot<a
name="dx10-47048"></a>. It has five keys for WL = &#8221;Wing-Leveler&#8221;,
&#8221;HDG&#8221; = &#8221;Heading&#8221;, NAV, APR = &#8221;Glide-Slope&#8221;, and ALT = &#8221;Altitude&#8221;. These keys
when engaged hold the corresponding property.
<!--l. 348--><p class="indent"> A detailed description of the workings of these instruments and their use for
navigation lies beyond this Guide; if you are interested in this exciting topic, we suggest
consulting a book on instrument flight (simulation). Besides, this would be material for a
yet to be written <span
class="ptmbi7t---109">FlightGear </span>Flight School.
<!--l. 353--><p class="indent"> It should be noted, that you can neglect these radio instruments as long as you are
strictly flying according to VFR<a
name="dx10-47049"></a> (visual flight rules<a
name="dx10-47050"></a>). For those wanting to do IFR<a
name="dx10-47051"></a>
(instrument flight rules<a
name="dx10-47052"></a>) flights, it should be mentioned that <span
class="ptmbi7t---109">FlightGear </span>includes a huge
database of navaids<a
name="dx10-47053"></a> worldwide.
<!--l. 355--><p class="indent"> Finally, you find the throttle<a
name="dx10-47054"></a>, mixture<a
name="dx10-47055"></a>, and flap control<a
name="dx10-47056"></a> in the lower right of the panel
(recall, flaps can be set via <span
class="cmr-10--109">[ </span>and <span
class="cmr-10--109">] </span>or just using the mouse).
<!--l. 358--><p class="indent"> As with the keyboard, the panel<a
name="dx10-47057"></a> can be re-configured using configuration files. As
these have to be plane specific, they can be found under the directory of the
corresponding plane. As an example, the configuration file for the default Cessna C172
can be found at <span
class="pcrr7t---109">FlightGear/Aircraft/c172/Panels </span>as c172-panel.xml. The
accompanying documentation for customizing it (i.e. shifting, replacing etc. gauges and
more) is contained in the file <span

<!--l. 370--><p class="noindent">At current, there are two options for reading off the main flight parameters of the plane:
One is the instrument panel already mentioned, while the other one is the HUD<a
name="dx10-48001"></a> (<span
class="ptmb7t---109">H</span>ead
<span
class="ptmb7t---109">U</span>p <span
class="ptmb7t---109">D</span>isplay) <a
name="dx10-48002"></a>. Neither are HUD<a
name="dx10-48003"></a>s used in usual general aviation planes nor in civilian
ones. Rather they belong to the equipment of modern military jets. However, some might
find it easier to fly using the HUD even with general aviation aircraft. Several Cessna<a
name="dx10-48004"></a>
pilots might actually love to have one, but technology is simply too expensive for
implementing HUDs in general aviation aircraft. Besides, the HUD displays several
useful figures characterizing simulator performance, not to be read off from the
panel.
<!--l. 380--><p class="indent"> The HUD<a
name="dx10-48005"></a> shown in Fig. 6 displays all main flight parameters of the plane. In
the center you find the pitch indicator<a
name="dx10-48006"></a> (in degrees) with the aileron indicator<a
name="dx10-48007"></a>
above and the rudder indicator<a
name="dx10-48008"></a> below. A corresponding scale for the elevation<a
name="dx10-48009"></a>
can be found to the left of the pitch scale. On the bottom there is a simple turn
indicator<a
name="dx10-48010"></a>.
<!--l. 386--><p class="indent"> There are two scales at the extreme left: The inner one displays the speed<a
name="dx10-48011"></a> (in kts)
while the outer one indicates position of the throttle<a
name="dx10-48012"></a>. The Cessna 172 takes off at around
55 kts. The two scales on the extreme r.h.s display your height<a
name="dx10-48013"></a>, i. e. the left one shows the
height above ground while the right of it gives that above zero, both being displayed in
feet.
<!--l. 392--><p class="indent"> Besides this, the HUD<a
name="dx10-48014"></a> delivers some additions information. On the upper left you
will find date and time. Besides, latitude<a
name="dx10-48015"></a> and longitude<a
name="dx10-48016"></a>, resp., of your current position are
shown on top.
<!--l. 395--><p class="indent"> You can change color of the <span

side of the knob/lever decreases the value, while clicking on the right hand side increases
it.
<!--l. 418--><p class="indent"> Right clicking the mouse activates the simulator control mode (cross hair cursor).
This allows control of aileron/elevator via the mouse in absence of a joystick/yoke

<!--l. 454--><p class="noindent">This is the Official Guide to Basic Flight Information and ATC Procedures by the FAA. It
contains a lot of information on flight rules, flight safety, navigation, and more. If
you find this a bit too hard reading, you may prefer the FAA Training Book<a

<!--l. 460--><p class="indent"> <a
href="http://avstop.com/AC/FlightTraingHandbook/" >http://avstop.com/AC/FlightTraingHandbook/</a>,
<!--l. 463--><p class="noindent">which covers all aspects of flight, beginning with the theory of flight and the
working of airplanes, via procedures like takeoff and landing up to emergency
situations. This is an ideal reading for those who want to learn some basics
on flight but don&#8217;t (yet) want to spend bucks on getting a costly paper pilot&#8217;s
handbook.
<!--l. 469--><p class="indent"> While the handbook mentioned above is an excellent introduction on VFR<a
name="dx10-50004"></a> (visual
fligtht rules), it does not include flying according to IFR<a
