INSIGHTS AND TIPS
ON THE LHC LJ24B
INSIGHT ONE; LIGHTING
The LHC LJ24B has 3 Lighting Zones, all controlled
by the 3 switch knobs on the left side of the Captains
elbow panel. These control the Cockpit Dome Light
(very bright), the Instrument Panel lights (all the
gauges 'alone', not the dome light, great for night
flying), and then the rear Cabin lights back around the
There 'is' a Panel light on the instrument panel with
the rest of the 'lights switches' This is a redundency
light switch. Just use the one on the side panel. It
has a cooler 'click' sound.
INSIGHT TWO; BUBBLE PLACCARDS
By clicking on a un-marked black button on the top left
of the Annunciator buttons / lights on the instrument
panel hood, you will be suddenly surrounded by a load
of information bubble placcards that have small tails
that touch on key buttons and switches that you will
need to know about in the cockpit of the LJ24B.
Note also 'Blue' placcards with A-2, A-3, etc. These
are for noting the 'Popup Panels' and also 'Camera
Views'. Shift 2 through Shift 5 will give you these
groups view points in Camera view mode (in VC, click
A several times to rotate through the many views).
Also are popup panels with those numbers. Shift 2 for
instance in the far left corner is 'Audio Panel'. You can
view the popup easily by clicking Shift- 2 (via the A-2
Lear to memorize the various stations and popups.
INSIGHT THREE; FUEL TRANSFER
The LJ24B features aux fuel cells (2) in the Fuselage.
They are small and handled like 'one' fuel tank. When
your flight starts, your fuel is automatically taken from
the Wing Tip Tanks (not the wings). When you run out
of fuel in the Tips, your automatic fuel selectors in the
wings (valves) switch over to the Wing Tanks. When
you are low in the wings, you can then 'transfer' fuel
from the Fuselage tank to the Wings. If you do not
move the fuel to the Wings, your engines will starve out
(burn out) even though you have fuel on board. You
must move the fuel to the Wings to use the aux fuel.
NOTE: There is 'no' fuel selector, only the transfer
toggle and the cross flow toggle. The rest is all
automatically handled by way of tank valves.
Insight: You can dump fuel from your red toggles on the
Fuel Management Panel or on the Fuel Map Display.
INSIGHT FOUR; LANDINGS AND WING TIP TANK FUEL
The actual 'early' 20 series LJ's were 'not' to be landed with fuel in the 'Tip Tanks'. You had to purge (jettison) the fuel
before landing 'if' you still had fuel in them. So, for realism, we have made the landing gear 'weak' so that if you do land
with fuel in the tip tanks, you had better land super smooth or you collapse your landing gear on your sleek LJ24B and
you'll need to take her to the shop to get the entire underbelly repaired. The actual planes would have 'wing spar damage'
but we couldnt replicate that, so we went with landing gear damage.
You are now warned. Land smooth with 'empty' Wing Tip Tanks.
INSIGHT FIVE; VAPOR EFFECTS FROM WHERE....
The LJ24B by LHC is an EFFECTS MONSTER,
having a ton of various effects throughout, ranging
from vapor effects to sound effects.
FUEL DUMP VAPOR TRAIL
When jettisoning fuel in the LJ24B, you will see a
stream of fuel vapor and spattering drops trailing out
the Tip Tanks. Its a LOT of fuel leaving them fast. In
Reality, its not that moderate.
SPOILERS CON TRAIL
When you deploy your spoilers, you will have
The insides of the engine exhausts will also glow an
orange-ish color which increases with brightness as
you increase throttle.
INSIGHT SIX; BELLY LANDINGS POSSIBLE
For those of you that like to simulate emergency
procedures, we have made the LJ24B able to be
landed on her belly with the landing gear up. We
use special contact points that allow this.
However, you must land smoothly or you still
crash. Normally with most FS aircraft, you 'do'
crash the plane when landing with gear 'up', but
not on the LJ24B.
If you are 'reallllllly' good on smooth, slow
landings, you might be able to land her on the
water without the 'crash' event occuring.
INSIGHT: An alarm will sound off that alerts you
that your landing gear is 'up'. This happens on an
approach during descents.
INSIGHT: If you are flying in Active Realism
mode, you have the ability to fry a turbine. If such
an event occurs, you will lose hydraulics as the
pumps are driven from the jets. But, if you act
quickly while you still have battery power, you can
lower your gear, down and locked, by holding the
starter 'on'. This will get your gear down, but
otherwise you will have to find a smooth grassy
field or runway in glide distance to belly land at.
(The engines starters will not rev up if you are out
of electric power).
INSIGHT SEVEN; THE COOL FUEL MAP DISPLAY
When building the LJ24B, I wanted a visual for
the fuel tanks, so I created a sort of 3D looking
layout of artwork that features all the fuel cells
seen from above. These 'lower' in fuel level as
you burn (tons) of fuel. I added 'digital' Pounds
readouts so pilots can see how many Pounds of
fuel they have in the tanks as well, seeing both
Pounds and the 'visual' of how much fuel you
have really helps, (at least for me).
I then added click zones to the 'Tip Tanks' so
you can 'quick-jettison' fuel. This happens very
fast, but so fast that you can actually starve a jet
engine before the automatic fuel selector
system can switch over the fuel drink points, so
beware, when jettisoning fuel, that you 'stop' the
fuel purge by clicking it 'again' to keep from fully
dumping your fuel or you just may have to restart
INSIGHT EIGHT; YAW CONTROL AND AUTOPILOT MANAGEMENT
INSIGHT: The LJ24B featured a cool 'Remote Autopilot'
control console on the instrument panel. The regular
Autopilot Management Panel is located on the Center
Console between the seats. Having the 'Remote' button
panels on the main Instrument Panel allowed you to 'see' in
front of you what switches were on.
You still have to turn 'on' the AP system via the Center
Console Autopilot Manager Panel.
INSIGHT: Did you know that you ALWAYS flew your Learjet
with 'Yaw Control' ON? Yes. The only time you turned this
off was when you were landing. The Learjet had a bit of a
Yaw issue, so it was very important to have Yaw on at all
times, especially at high altitude or you could get into a very
scary set of side to side opposite out banks that would get
the aircraft out of control. So, make sure you always have
Yaw 'on' and when landing, turn it off.
INSIGHT: The 2D popup and the 3D version 'trim wheel' for
adjusting 'vertical climb rate' can be adjusted with 'mouse
wheel' instead of going 'clicky clicky' 20 times. Saves you a
couple of min's.
INSIGHT NINE: INVERTER SWITCHES AND AC POWER
Some electric equipment on board your Learjet will run on
AC power. The DC power from the Batteries and or
Generators must run the power through 'Inverters'. You have
two, Primary and Secondary. These 'must' be turned on. If
not, you will not have Autopilot as the system uses powerful
servos that use AC power. You will see that the AP green
light will 'not' come on if you do not have your Inverters in 'on'
INSIGHT: You can flip between Inverters to see how much
power they are supplying via the left/right toggle switch just
above the 'AC VOLTS' Garwin readout. Flip that switch
back and fourth for readouts of AC Volts from each Inverter.
INSIGHT TEN: SETTING YOUR ALTITUDE
Adjusting your 'Altitude Setting' is done on this unique little
instrument. I just use mouse wheel, hovering it over the
actual digital numbers. You can use the knob if you so like,
but its small and in a busy flight, that can be difficult. The 2D
instrument panel will not have a functioning knob on it. Only
the VC version does.
INSIGHT ELEVEN: GPS / NAV SWITCH
For Flight Simulator, you have the infamous GPS / NAV
Its down on the bottom left of the 'Electrics Panel' (area of all
the electric buttons). Cant miss it. Remember, GPS ON for
flights with a flight plan or a GPS Direct-To flight, or NAV on
for doing VOR to VOR flights.
INSIGHT TWELVE: ACTIVE REALISM
This is a new 'frontier' for Lionheart Creations.
This is a dual realism option available in the
aircraft to 'turn on' difficulties.
If you want, for instance, to see if you can fly fast
and 'not' cook the engines, this is for you.
Simply turn on the 'Active Realism' toggle switch,
top center right on the Instrument Panel just above
the dummy 'Sync' instrument. With the 'Active
Realism' switch 'on', your engines will be in danger
of overheating (cooking, baking) and you are also
able to 'over-speed' the turbines.
Now, mind you, you can do this often on real jets,
and this does happen, but only for short moments
at a time. But in this case, we have set up a time
amount for these 'moments'.
** If Turbine N1 RPM goes above 95% for 9
minutes, your engine computer will shut down your
turbine. One will last longer then the other. You
can restart (hopefully, if you still have battery
power), after 1 minute of cool down.
** If you run your Turbines too hot (Exhaust Gas
Temp) at over 485 deg Celcius for 7 min's, you
have barbecued your expensive, exotic, powerful
CJ610 turbines. One will get a bit hotter then the
other, one will last less as long. After 3 min's of
cooling at high speed flight, you 'might' be able to
restart, if your batteries last long enough.
INSIGHT: They (the girls, the Engines) have names. Yep... Betsy
is the LH CJ610 and Ingrid is the RH CJ.
INSIGHT: Did you know the early CJ610's were 'single shaft'
turbines? They didnt have N2 on these.
INSIGHT: Did you know you have an anti-ice area on the front rims
of the intakes of the 'Ladies' (Jets)? Yes. You turn these on at the
Audio Panel 'Heaters' section.
INSIGHT: I have added yellow 'Blinker Lights' on the Exhaust Gas temp gauges. These blink when you are above 400C on
your Turbines. This will give you a 'hint' that you are getting into the Barbecue range with cooking your engines 'if' you have
'Active Realism' on.
INSIGHT THIRTEEN: WING TEMP
This is a cool feature I found in the Learjet Manual.
Wing Temp is critical as they are huge fuel tanks.
You can overheat the fuel in the wings. I then
created an algorthim that the gauge ran from. It will
show a hot set of wings occuring when the day is
hot and your speed is high. The equasion is only
slightly complex and gradual. If this occurs (like in
reality) the manual advises you to slow to 250
'indicated' and descend to FL 240 (or lower) until
your wings cool down.
They had this for the Nacelle pylons also, but that is
not modelled. I have this also for the Batteries, and
if you watch their temp gauge, you will see that
raise a bit.
INSIGHT FOURTEEN: ASI INSTRUMENT
The Lear ASI in this aircraft is equipped
with a 'digital' Mach Readout, (top
window). The Bottom window is 'Knots'
There are also 3 markers in color; orangish
faded red, yellow and white.
* RED.... Max Knots Indicated
* WHITE..... Rotation Point (Takeoff)
* YELLOW.... Stall, Full Flaps
INSIGHT: The knob on the bottom left of
the instrument is a dummy. There is no
'Speed Setting' (Autopilot feature) on the
LJ24B, so ignore that.
INSIGHT FIFTEEN: HEATERS AND AUDIO CENTERS
Note that all of your 'Heaters' switches are located in one nice
little area, far left corner of the Instrument Panel. The top part of
that triangle like area is the Heaters.
INSIGHT: You have Window Heater. This must be on at high
altitude, but if you are low in altitude (like on approach) and its
very hot out (like in Phoenix Arizona or Cairo Egypt), then turn
that off, as your window (glass) will be more susceptable to
breaking or cracking when its 'really hot' (speed and friction
from thick air at low altitudes) compounded by possible bird
strikes. So turn that off when you are low and its hot out.
The bottom of that little triangle area is your Audio Panel. Note
there is a Phone option in there. That was high technology back
then to have a phone in a plane, let alone without a telephone
pole, (wireless). Such technology....!
** Heaters.......... All Deice Equipment; Pitots, Wings, etc.
INSIGHT SIXTEEN: RADAR ALTIMETER
The Radar Altimeter is 'off' until you turn it on.
The 'ON' switch is the little chrome toggle just to
the left of it. Turn that on (up) and the RAD ALT is
'active'. It is on X100 feet, so '2' will be 200 feet
above the deck. Use the black knob on the
instrument to adjust your 'altitude alert' setting.
INSIGHT: Did you know you can hide the
steering yokes? Click on them to hide them. But,
how do you unhide them? Click on that black
round knob nex to the Radar Altimeter chrome
toggle switch to bring the yokes back.
** The LJ24B will 'not' start or work right (engines, fuel system, avionics, etc) if you use another planes
cold and dark save point to start up in. You MUST use a pure, running start point in the Learjet and then
shut it all down and save and create a 'pure' LJ24B cold and dark saved flight file. You can also download
our new 'cold and dark' save files (2) here, on the LJ24B webpage under the sales section, free download
of the save points.
CONTROL YOKE BUTTONS ARE NOW ACTIVE
The four buttons on the pilots control yoke are not functioning and control several systems on the LJ24B.
Top Left: Electric elevator trim, up down, controlled by 'Mouse Wheel'
.................Same Knob; Autopilot Heading Adjust, left right, via Left Click and Right Click
Bottom Left: MIC Button; brings up the ATC window
Right Top: Autopilot On / Off. When turning on the AP, the AP ARM (yellow annunciator) will come on letting you
.................know that the AP system if on and active.
Right Bottom: Cheater Button that turns on all systems that normally require you to turn them on. These are
normally coded outside of keyboard shortcuts. This allows you to turn everything on to go to instant flight readiness.
