ATC
The Air Traffic Control Simulation Game
Copyright 1990
by Griff Jackson
Release 00.00
(SHAREWARE $15)
ATC is a program that simulates an air traffic regional control center.
You are the controller, and you direct the planes (up to 8 at a time) to
the airport. You control the planes' heading, altitude and speed. You
receive points for directing the planes correctly to the airport. You
also have to contend with planes departing from the same airport, and
you have to make sure that the planes do not collide with each other.
You also have only a limited amount of time to get the plane to the
airport. You receive fewer points for a late flight, and if a flight is
very late, it will run out of fuel and crash. All program input is done
with the left mouse button.

INSTRUCTIONS:
To run ATC, type "ATC" from the CLI or click on its icon It will take a
few seconds for the program to load. Once it has loaded, you will be
presented with the "Set Up" screen. Here you have a few choices to
make:
ATC has three levels of difficulty: easy, medium, and difficult. The
differences between the levels are things like the amount of time the
flights are spaced apart and how quickly the planes respond to changes
in altitude or speed.
ATC uses the Amiga's built-in speech facilities. If you want to hear
the speech, select "Sound On"; otherwise select "Sound Off". If you are
playing the difficult level, the speech facility can slow the game down
when many flights are in your airspace - especially when playing with
more than 20 total flights.
To select levels or sound, you must first unselect the item which is
already selected - then select the new entry. The defaults are "Easy"
and "Sound Off".
The "Number of flights" button controls the game length and difficulty.
A game with 100 flights will last about an hour; 20 flights about 10
minutes. Shorter games are usually easier to play - the action does not
get quite so fast and furious. Be sure to press RETURN after changing
the number of flights.
When you are satisfied with the set up, select the CONTINUE button.
Then the screen will change to purple, and after a few seconds, the
radar screen will appear and the game will begin.
The object of the game is to direct incoming flights to the airport for
landing and to direct departing flights out of your airspace. The
airport resides at the center of the green sweeping radar line. Before
an aircraft can land, its heading must be 180, speed - 100, altitude -
500, and the distance must equal 0. A successful departure is at 20000
and a speed of 400 when the aircraft leaves your airspace. The game is
over when the last scheduled flight has either landed or left your
airspace.
THE RADAR SCREEN
Flight Status Display
In the upper right hand corner of the screen is a blue rectangle in
which information about a selected flight appears. When the program
first starts up, some of the information will be zeroes until a flight
is selected. Here's a description of the data appearing in the blue
rectangle:
Fl #: - the flight number for the selected flight. Also displayed
is the "In" or "Out" indicator which shows if the flight
is arriving or departing. The flight number consists of
two parts: a 2 digit abbreviation for the airline name
and a three digit number. ATC has four airlines:
BA - Beta Airlines
CO - Consolidated Airlines
IC - Intercontenential Airlines
NA - National Airlines
Stat: - There are three possible statuses:
Normal - everything's ok
Priority - the flight is late
Emergency - the flight is low on fuel
Schd: - This the scheduled arrival or departure time. ATC always
begins with an arriving flight scheduled to arrive by
8:45 in the morning. Note: flights enter your airspace
approximately 45 minutes before their scheduled arrival
time. When the airport is particularly busy, some
flights may enter your airspace later.
Dist: - This is the flight's current distance from the airport.
The flight can't land until the distance reads zero.
Head: - This is the flight's current heading. There are eight
possible headings: 0, 45, 90, 135, 180, 225, 270, 315.
To change the current heading, click on the up/down
arrows to the right of the display. To land, a flight
must have a heading of 180, that is, all landings must be
to the south. Also, all departures are to the south.
Alt: - This is the flight's current altitude. There are six
possible altitudes: 20000, 15000, 10000, 5000, 1000, 500.
To change the current altitude, click on the up/down
arrows to the right of the display. To land, a flight
must be at 500 feet.
Spd: - This is the flight's current speed. There are four
possible speeds: 100, 200, 300, 400. To change the current
speed, click on the up/down arrows to the right of the
display. To land, a flight must have a speed of 100.
Fuel - This is the current amount of fuel left. If the amount
goes under 50, the flight's status changes to "Emergency."
IF the amount goes to zero, the flight crashes.
Flight Schedule Display
Just under the Flight Status Display is a white box - the Flight
Schedule Display. This box will display the arrival/departure time for
all flights. To cycle through the flights, click on the up/down arrows
to the right of the box.
Flight Message Display
Just under the Flight Schedule Display is a black box - the Flight
Message Display. All messages from the aircraft to you will appear in
this box. If speech is enabled, the messages appearing in this box will
also be reported verbally.
TOD Display
This box displays the game's current time of day in hours and minutes.
You will notice that the game's time of day moves along quite a bit
faster than real time.
