                            NEW HUD FEATURES
                            ----------------

THE VELOCITY VECTOR
-------------------
The velocity vector symbol in the HUD represents the aircraft's actual
direction of flight which may be different from the direction that the
aircraft is pointing.  For instance, during a landing approach, your nose
may be pitched up slightly above the horizon, but your direction of flight
is descending toward the runway and this symbol will be pointing to the
runway.

INERTIAL NAVIGATION SYSTEM (INS)
--------------------------------
The Inertial Navigation System will help direct you toward your desired
destination. 

1.  When you are in a bombing mission and select a ground target
    in the MFD (right CRT), the INS automatically points toward
    the target in the heading scale of the HUD.  

2.  When you engage the CLS (described below), the INS automatically
    directs you toward your point of origin, the aircraft carrier or 
    an airbase.

The INS appears as a ^ in the heading scale of the HUD, to direct you
toward your point of origin, or the current ground target site.

INSTRUMENT LANDING SYSTEM
-------------------------
Using the Carrier/Instrument Landing System (CLS-ILS) will greatly aid
you in your return to carrier or airbase, and in landing safely.

To engage this system, toggle the MMD (left CRT) with the "F1" key to
bring up the "CLS-ILS" display.  Recall that it appears as a ^ in the
heading scale. Turn your aircraft until the ^ indicator is centered in
the heading scale.



JETFIGHTER:The Addendum............................................ Page 3

Turn your aircraft until the ^ indicator is centered in the heading scale.
Now that you are flying toward your airbase, check your range (distance)
from the airbase in the CLS-ILS display.  When you are within 40 miles
from base, bring your altitude to approximately 5000 feet or so.

When you are within 30 miles from the base, the Instrument Landing
System automatically engages and is displayed in the HUD as two dotted
bars: one vertical and one horizontal.  These bars indicate your
position with respect to the "glide slope" of the runway on which you
will be landing. This glide slope is determined by a "beam" which is
projected from the ideal landing point on the runway at the perfect
approach angle. Your task is to "ride down this beam".

To line up your approach with the runway, the vertical bar must be
centered in the HUD.  If the vertical bar is left of center, then turn
your aircraft left to a heading of about 45 degrees from your current
heading (that is, if you have been heading directly for the base).
You will notice the INS pointer (which points to the runway) slide to
the right.  That's okay, because you have to come around to the proper
approach of the runway.  If the vertical bar is right of center, turn
to the right. The INS pointer will slide to the left.

When the vertical bar begins to move toward the center of the HUD, you
will soon be lined up with the runway.  Begin to turn toward the runway
using the INS pointer and adjust your turns to center the vertical bar
in the HUD.

When you are within approximately 15 miles from the runway, you will
want to prepare to intercept the glide slope beam.  Bring your throttle
to 60%. The horizontal bar should be above the HUD center at this
altitude and this distance from the runway.


JETFIGHTER:The Addendum............................................ Page 4

When the horizontal bar begins to move toward the center of the HUD,
you will soon be intercepting the beam.  At an altitude of 4000 feet,
you should intercept the beam at about 5 miles from the runway.
Reduce your throttle to 50% which should bring your speed down to
about 220 knots.

         (Remember to keep the vertical bar centered). 

Bring your landing gear down. If you are landing on a carrier, extend
the arrestor hook.  When the horizontal bar reaches the center of the HUD
(with the vertical bar centered), you are "on the beam".  Reduce your
throttle to about 43% (+ and - keys provide fine adjustment) and pitch up 
slightly until the nose is just above the horizon. Be careful not to nose 
up too much which could cause a stall. You will notice the velocity vector
symbol move downward showing your current flight path toward the runway.

You can always turn off the CLS-ILS if you prefer to continue the landing
approach by purely visual means.  Otherwise maintain the centering of the
vertical and horizontal bars while paying attention to the approaching
runway surface.  After some practice, you'll be able to land while either
watching the ILS directly or watching the runway surface directly, while
subconsciously noting the ILS indicators that guide your approach.

If you are landing on the carrier deck, and miss the arrestor cables, hit
100% thrust IMMEDIATELY to bolter and go around for another try. 

IMPORTANT NOTE:
    If your approach happens to be coming in to the other end of the
    runway, the ILS will not help you, since it is tracking the beam
    projected out the opposite end of the runway.

BRIGHTNESS SETTING ON THE HUD
-----------------------------
You can set the brightness level of the HUD by pressing H. This toggles
the brightness level, from brilliant to dim, and then toggles to the off
position. The program automatically adjusts it to a proper setting, but
it is under your control.

                            GENERAL NOTES
                            =============

The following are hints for people which may make gameplay more enjoyable.

1) Adjust Contrast & Brightness on your monitor to best display the
control panel & HUD info. Depending on your monitor type and the
room lighting, you may need to make certain adjustments to the contrast
and brightness levels on you monitor to see the control panel correctly.
Also, you should make a point to make the ground color (color of the earth)
a rich brown and the midday sky a pleasant blue. Some settings will make
the ground a washed out yellow, and this can be corrected by adjusting
your monitor.

2) Remember that the Original Product disks ALWAYS work, even after you
install the program on your hard drive.  This means you can have two
working copies.

3) On the radar screen, if the other aircraft is a WIDE (double thickness)
line, then he is above you in altitude.

4) Remember that you only need one hand to work the keyboard letter
controls. SHIFT NEEDS ONLY ONE HAND... so you can eject by pressing SHIFT
and THEN pressing 'E'. 

5) Also, the SHIFT key reverses the order which multiple selections are
toggled. "Shift-Enter" reverses the order that you scan thru the armament,
so if you can go back to the last weapon without cycling through all the
weapons. Accordingly, "Shift-F2" reverses the order that you go thru the MFD.

6) The 'tilde' key (left of the '1' key across the top of the keyboard)
now gives you ZERO thrust. (Also, hitting "1" twice still works to shut
down the engines).

7) If you ZOOM-IN on the Map View, you can now see the Airports!

8) The ILS will guide you back to the Originating Point (airport or
carrier) that you originally took off from.

9) The INS points to Originating Base when you turn on the CLS-ILS.

10) The INS will give you direction of target WHEN you enable BOMBS and
have as active Ground Target.  ---- BUT, if the CLS is on ---> it will
point you to the Air Base !!!  So remember that the CLS overrides Ground 
Targets in the INS display.


JETFIGHTER:The Addendum............................................ Page 6
 
11) In the practice Dogfight Sequence in the Training Missions, how do you
know when you have RADAR lock on the instructor?  You have a lock when
you hear a solid tone on the speaker & it says "IN RNG" on the HUD !!!

12) If you are having a heck of a time getting through a mission, take heart!
If you fail any mission 4 times (without quitting that mission) it will
qualify you for the next mission. NOTE: since you need 4 carrier landings
to qualify -- this comes to 4x4=16 failed attempts to qualify for missions.

13) On the first training mission, you can have a lot of fun if you try
flying along side the instructor!

14) Remember, the only training mission you have to complete is the 
final qualification consisting of 4 carrier landings! The others are 
not required for combat status.

15) PS/2 Users!  It is important to remember that MCGA (the standard
graphics adapter for the Model 25 and Model 30) is NOT the same as
EGA or VGA.  To run JetFighter, you will need to upgrade to an EGA
or true VGA system. RUN THE "TEST" IN THE "INSTALL" PROGRAM TO SEE
WHICH VIDEO ADAPTER YOU HAVE!!

16) Norton Disk Optimizer Users!  Although we took pains to insure that
our on-disk copy protection would be as benign as possible, and would be
fully compatible with many disk tools, it makes sense not to take chances,
therefore, it is recommended at this time that you RECALL the protection
before you optimize or COMPACT the disk.

17) 512 K RAM Users!  If you can't get enough memory to load JetFighter,
strip down the autoexec.bat, config.sys, and remove all TSR's. If it still
doesn't have enough memory, and you are using DOS 3.3 or newer, you might 
look around for an older smaller, version of DOS (DOS 3.1 works fine). To 
see if you have sufficient memory to run the program, run TEST on the 
Program Disk. JetFighter should then load with a smaller version of DOS.

18) Small bug alert!  If you review a mission, don't use the backspace
key to erase the mission number entry. It might change your call sign
spelling! You'll have to escape (ESC key), and re-enter the selector.
Also, use of the arrow keys here seems to lock up the keyboard. Sorry
guys! Be sure to back up your flitlog.dat!

                    Question and Answer Period
                    ==========================
The following are answers to commonly asked questions about JetFighter.

PROBLEM: I am having problems installing or loading the program.

ANSWER: Please refer to the TROUBLESHOOTING guide in the user's manual,
located in Appendix A.

PROBLEM: My joystick seems to be messing up. It turns weird, and it
even turns when I'm not using it.

ANSWER: If your centered position on the joystick causes the plane to
turn, then you have a miscalibrated joystick. The program attempts to
automatically calibrate the sensitivity and positions of your
joystick at start-up. It might be improperly calibrated, because you 
were playing with it while the program was booting, causing an erroneous 
reading to be taken. To solve the problem...

    1) Simply let the joystick return to it centered position, and 
       press Shift-Y on the keyboard during program operation. This 
       will recalibrate the joystick. 

    2) Also, if you are playing on the keyboard, and you accidentally
       bump the joystick, the program might decide that you want to
       change to the joystick, and it will override keyboard input.
       In this case, press Shift-Y, and it will recenter the
       joystick, and return control to the keyboard.

    3) If the joystick starts acting really weird, and the Shift Y
       recalibration doesn't work, you may need to reboot the system.

PROBLEM: Okay, I'm finished playing the program. How do I un-install
it? What should I do?

ANSWER: To un-install, which basically allows you to re-install at a
later time, insert the Original JetFighter Data Disk into Drive A:,
and execute the batch file 'recall.bat', by typing:

     C:\JETFIGHT>recall c: a:

This will return the authorization to the Originals.


JETFIGHTER:The Addendum............................................ Page 8


            The following are GamePlay related questions.
            ---------------------------------------------

PROBLEM: Where are the enemies?

ANSWER: Let us assume that you've successfully completed the training
missions, and are in your first combat mission. Well, when you take
off from the carrier, the enemy is far beyond your radar range. 

A vector for target interception is given in the mission tactical orders.
The orders will tell you the range and heading of the bogey, and even
give you a VECTOR. Aim in this direction and you will eventually spot
him on your radar screen. Finally, you can always spot the enemy in
the Satellite Radar Mode, by pressing the 'M' key. You can zoom out
in the Satellite Radar Map by pressing the period key (>), and zoom in
with the comma key (<). Enemy are represented by red triangles about
a quarter of an inch long and you are the white triangle. The carrier
looks like a little carrier!

Now, once you have the enemy in your radar, you still won't seem him
because he is out of visual range. It sometimes helps to track him
with the on-board targeting computer, accessed by pressing the 'T'
key until the target is blinking on your radar display. You should
also press the Function-5 'F5' key to access the Multi-Function
Display for air target tracking. This displays the identification of
the bogey's radar signature (once it is close enough to resolve it),
his speed, heading and altitude. This is a useful display. You might
be right below the enemy, or on top of him, and you wouldn't even
know, unless this display told you so!

PROBLEM: I can't win the dogfights.

ANSWER: Here are a few hints that may help you learn successful
aerial combat maneuvering. There are three phases of jet combat:
closure, maneuvering and disengagement. If you are attacking, it is
pretty inefficient to go head to head, and let him know about you
from the start. You can't just mix it up with him once you get there.


JETFIGHTER:The Addendum............................................ Page 9
                                                          
It is much better to sneak up on the opponent by concealing yourself 
during the closure. Do what you have to, to surprise him. Try approaching
from a much lower altitude and attacking upward, or closing from much
higher altitude and attacking from above, preferably from the angle
of the sun. It is even useful to sneak around him and attack from the
rear, on his six.

Once you are in a dogfight, and you seem to be in a stalemate, and
the opponent is not making enough mistakes to let you take the
advantage, you might try an extension maneuver, like a split-S, to
get away from him on afterburners, get behind him, and then renew the
attack later.

It's all a game of strategy and tactics. It takes a while to become a
chess master. Expect to take a while to become a fighter pilot.

PROBLEM: I destroyed the first bombsite, but how do you get the second one?

ANSWER: The 'T' key, that you used to cycle through aerial targets,
is also used to cycle through ground targets.

PROBLEM: How can I get multiple flight logs to support multiple players?

ANSWER: Actually, your software license allows only one CPU to play
the game at a time. You might finish the game, recall the installation,
and then give your diskettes to your friend.

If it is another family member that wants to play, you might create
another directory, C:\JFIGHT2, and copy all your JetFighter files to
it. When your buddy plays the game from THAT directory, a different
flight log is created in that directory. That's the best we can do.

    HERE ARE SOME TIPS FROM ONE USER WHO MASTERED CARRIER LANDINGS:

When flying JetFighter, The Adventure (tm), you are required to
make a number of carrier landings to qualify for flying real missions.
This is not an easy task, but mastering it will allow you to enjoy an
already amazing and enjoyable game even more.

Let's review the techniques already discussed in both the written
documentation and in the simulation itself.  First, you should assume what
is called the "Marshall Position", at approximately five miles and about
five thousand feet Above Sea Level (ASL).  Turn towards the carrier.  At
this point in space, it is difficult, at best, to determine exactly what
heading the carrier is at, so simply flying towards is all that is needed.
Be sure that your power is at 40-45%, and that your gear and arresting hook
have both been deployed.

To ensure the proper decent angle, try to keep the rear of the carrier
deck between or below the artificial horizon markers on the Heads-Up 
Display (HUD).  Watch your airspeed.  If you find yourself moving
at more than 180 knots, reduce your power to 40% (never below).  If you are
approaching a stall, it may be best at this point to scratch the landing
and go around.  If you can, fly by the carrier before setting up again, to
attempt to determine about what heading is needed to hit the cables.

We will assume at this point that the landing is proceeding as planned, 
and that your position is relatively behind the carrier (340 to 020
degrees of heading).  When you are close enough to the carrier to
determine about what its heading is, you should begin to think of the
compass on the HUD as extending all the way around your head.  Turn the
aircraft slightly away from the carrier, until such time as the wake of the
carrier is nearly parallel with the heading you need for landing, then turn
back towards the carrier.

Remember to watch your altitude.  You should be about 1000 Feet ASL at
about a mile away from the carrier.  Don't dive too much towards the
carrier, and do not make any harsh or excessive movements while on final
approach.  Try to keep your turns smooth and shallow, and make any pitch
changes gradually.

Right before touchdown, make sure that both the hook and the landing gear 
are actually extended.  Keep your eye on the landing, but put your finger
over the "0" on your keyboard, in preparation for full power in the case 
of a "Bolter", or botched landing.  Remember, you usually have plenty of
time and fuel to make a landing.  Trying to force the landing will almost 
always end up in a crash.

In conclusion, it is important to know that landing an aircraft is the
singular most difficult and dangerous part of flying, whether on land,
water, or the deck of a carrier.  Be patient, try to determine what went
wrong last time, and try to learn from your mistakes, and you will have one
of the most important virtues of a real pilot.

These tips were written by Stephen C. Gresser.  [Thanks - Ed.]
