Planes for Chuck Yeager's Advanced Flight Trainer
AFTPLANE.ARC
by Rus Phillips 12/19/87
(C) Rus Phillips 1987
1. Files in this archive:
AFTPLANE.DOC - This file
ZERO.FLY - Mitsubishi Zero airplane file
F-20.FLY - Northrop F-20 Tigershark airplane file
GRIEPEN.FLY - Saab Greipen airplane file
2. How to use the files:
The airplanes in this file require the use of Chuck Yeager's
Advanced Flight Trainer (formerly known as Advanced Flight Simulator)
from Electronic Arts. To use the planes, simply put them on the same
directory as AFT. AFT will find it and place it in the "planes" menu.
3. The airplanes:
-------------------------
Mitsubishi A6M Zero-Sen
Engine: 1 Misubishi Kinsei 62 (1,560 hp)
Wingspan: 36 ft., 1 in.
Length: 29 ft., 9 in.
Maximum weight: 6,944 lbs.
Landing gear: retractable wing gear, retractable tail wheel
Service ceiling: 39,370 ft.
Maximum speed: 360 mph
Crew: 1
The Zero was the aircraft that the Japanese used throughout
World War II. At the beginning of the war, it could outfly anything.
But by 1944, American planes like the P-31 could shoot it down easily.
------------------------
Northrop F-20 Tigershark
Engine: 1 General Electric F404-100 augumented turbofan (17,000 lbs.
static thrust)
Wingspan: 26 ft., 8 in.
Length: 47 ft., 10 in.
Maximum weight: 27,500 lbs.
Landing gear: retractable tricycle
Service Ceiling: 50,000
Maximum speed: Mach 2 (1,320 mph)
Crew: 1
This high-preformance jet fighter was privatley funded for
a US Department of Defense contract for an export fighter. It is the
fastest-climbing interceptor in the world. Although it had many good
qualities, the DoD decided to drop the project.
------------------------
Saab Grypen JAS 39
Engine: 1 Volvo Flygmotor RM12 augumented turbofan (18,000 lbs. static
thrust)
Wingspan: 26 ft., 3 in.
Length: 45 ft., 11 in.
Maximum weight: 17,645 lbs.
Landing gear: retractable tricycle
Service ceiling: 50,000?
Maximum speed: Mach 2 (1,320 mph)
Crew: 1
This is Sweden's newest jet fighter. It is currently still under
development. It has a canard foreplanes and a delta wing. It is desinged
as a STOL aircraft (Short Takeoff or Landing). The Grypen can take off
in 3,280 feet of runway. The engine is a licensed version of the GE F404.
British Aerospace is making a carbon-fiber wing for great strenth.
4. How are new planes programmed?
AFT keeps its airplane stats in small ASCII files called *.fly.
These files include number values for all of the flight characteristics of
the aircraft. Using these numbers, it is concieveably possible to simulate
any conventional aircraft! What follows is an example file and what we think
the numbers do. The numbers to the far left are not included in the files and
are for reference only.

5. Comments
The files in this archive would not have been possible without the
tireless work of Kirk Wagner, who figured out what most of the number values
do. He has done this after hours of tinkering with the airplane files.
I myself have only figured out four or five of them. Kirk has written a
file called AFS747.ARC, which gives a more detailed description of how the
*.FLY files work and comes with a 747 to fly. Kirk's GEnie adress is:
SHRIKO.
Since I am not sure what all of the number values do, these plane
files are not perfect. Nor have I ever flown a real airplane. At best,
they should be realistic simulations of the real thing.
Now, if you figure out what some of the unknown values are, please
tell me! I'd really love to know so I can create better aircraft. Also, if
you create any new airplanes, please upload them so they can be shared. I
love to get new airplanes to use. The only things I used to create my planes
was a book with statisitcs on the plane, what I thought the plane could do,
and some guesswork. Please leave me comments on what you think should be
improved, anything you have discovered, or your opinion. Your comments will
encourage me to post more airplanes, stunts, and airplane races in the
future.
If you have any comments or questions, I can be contaced at the
following address.
