TYJETSET.DOC 747 FLIGHT SIMULATOR (JETSET)
--- ------ --------- --------
The program on this BBS called 747.BAS was originally written up in
the November, 1982 issue of BYTE magazine under the title JETSET.
The documentation that follows is only excerpts from the complete
documentation found in that magazine. To try to reproduce all of it
here would take too much memory. Also, there are drawings that cannot be
reproduced.
With the Jet Simulator Electronic Trainer (hence JETSET),
you'll maneuver an aircraft through the three stages of flight -
takeoff, cruising, and landing - in less than ideal conditions. The
program, originally written for the TRS-80 and modified for the IBM-PC,
uses the keyboard and screen to make a personal computer verf_on of a
commercial flight simulator. You and the controls, of course, remain
firmly planted on the ground. JETSET is flown according to Instrument
Flight Rules (IFR).
Listed below are the keyboard keys, functions, and definitions:
KEY FUNCTION DEFINITION
--- -------- ----------
F THRUST INCREASE* INCREASES POWER TO JET ENGINES
S THRUST DECREASE* DECREASES POWER TO JET ENGINES
Q THRUST REVERSE REVERSES ENGINE THRUST DURING LANDING
D PITCH DOWN* LOWERS NOSE OF AIRCRAFT BY 5 DEGREES
U PITCH UP* LIFTS NOSE OF AIRCRAFT BY 5 DEGREES
\ PITCH CANCEL SETS NOSE TO LEVEL FLIGHT
< RUDDER LEFT* INCREASES RUDDER LEFT BY ONE INCREMENT
> RUDDER RIGHT* INCREASES RUDDER RIGHT BY ONE INCREMENT
/ RUDDER CANCEL RETURNS RUDDER TO CENTER POSITION
L FLAPS RAISES AND LOWERS Wu FLAPS
W WHEELS RAISES AND LOWERS LANDING GEAR
B BREAKS RELEASES WHEEL BRAKES FOR TAKEOFF
M MISSED APPROACH SIGNALS AN ABORTED LANDING ATTEMPT
V VOR FREQUENCY TUNE INPUTS A FREQUENCY TO VOR RECEIVER
R VOR RADIAL SELECT SELECTS A RADIAL VALUE FOR NAVIGATING
A VOR AUTO SELECT AUTOMATICALLY ROTATES RADIAL SELECTOR DIAL
NOTES: 1. The CAPS LOCK key must be engaged throughout the simulation.
2. An asterisk (*) identifies keys that may be typed additional
times to increase their control function.
The following procedures will allow you to takeoff from the
Philadelphia airport and, hopefully, land at the Buffalo airport. To
get a more detailed description of how this simulator works, I strongly
advise obtaining a complete copy of the documentation. See note at the
end of this writeup.
TAKEOFF PROCEDURE
------- ---------
A. Lower flaps (L key).
B. Release breaks (B key).
C. Apply full throttle (F key).
D. Steer along the 075-degree runway using the left/right rudder keys
(< and >). Coordinate steering with the COMPASS reading and the position
of the arrow located at the base of the runway graphic.
E. As soon as the AIRSPEED indicates 150 knots, press the U key once to
gently lift the jet off the runway.
F. After the horizon line drops below the screen, press the W key to
raise the landing gear.
G. Retract the flaps (L key).
H. Throttle back the engines (S key).
I. Sit back and relax for a minute or so as the jet gains altitude.
PRACTICE FLIGHT
-------- ------
A. Execute the takeoff form Philadelphia as described above.
B. Level off at 10,000 feet.
C. Steer approximately north.
D. Adjust airspeed to 600 knots.
E. Tune to the frequency of the Buffalo VOR station (115.5 MHz).
F. Input the value of 278-degrees radial into the receiver.
G. When the VOR needle moves to center, alter course to 295-degrees
(COMPASS).
H. Now steer to keep the VOR needle centered. This indicator, not the
compass, will provide exact guidance for the remainder of the flight.
I. Use the DME indicator to keep track of the distance remaining, in nautical
miles, to Buffalo. To estimate the remaining flying time (in minutes),
simply divide the DME reading by 10.
J. When the DME readout reaches zero, the jet has arrived.
INSTRUMENT LANDING
---------- -------
A. Execute the takeoff procedures.
B. Continue to climb to an altitude of 3000 feet on a course of 075
degrees.
C. At 3000 feet, alter course to 000 degrees and continue climbing.
Adjust thrust for airspeed of 580 knots. Tune VOR to Philipsburg
station (115.5 MHz), and set radial to 278 degrees.
D. Steer along 278-degree radial when intercepted. Level off at 40,000
feet and proceed to Philipsburg at 600 knots.
E. At DME=20 NM, retune VOR to Buffalo (116.4 MHz) and set radial to 346
degrees.
F. Upon intercepting the 346-degree radial, alter course to follow the
radial to Buffalo.
G At DME=73 NM, begin decent to 1900 feet (descend at approximately
11,000 FPM).
H. Level off at 1900 feet. Remain aligned with the radial.
I. Begin initial approach trim when DME=20 NM as follows:
1. Reduce airspeed to 300 knots (S key).
2. Drop landing gear (W key).
3. Lower the flaps (L key).
4. Adjust altitude to between 1700 and 1900 feet (elevator keys).
5. Keep the VOR needle centered (rudder keys) to stay on the initial
approach radial.
J. Be alert for the flash of the MARKER lamp (which occurs when the
DME=12). At this signal the jet must be maneuvered for the final
approach:
1. Quickly swing the nose until the compass shows 042 degrees.
2. Use rudder and elevator keys to keep the ILS indicator needles
centered as the jet descends along the glidepath.
3 As soon as the runway graphic appears on the screen, use the
graphic arrow as a guide to apply rudder corrections.
K. When the MARKER lamp flashes again to announce arrival at the decision-
height point, check the runway alignment using the graphic displayed on
the screen. If necessary, press the M (Missed Approach) key to abort
the landing attempt. Otherwise, if the plane is lined up safely, take
all cues from the RADAR ALT from here on in:
1. At 100 feet, idle the engines (S key).
2. At 50 feet, flare up the nose (\ key).
3. At 0 feet, the jet is on the runway. Slow it down by applying
reverse thrust to the engines (Q key).
Your JETSET flight concludes with a display of the landing information
that tells you how well you handled the jet. This information specifies
where ground contact occurred and where the jet finally rolled to a halt.
If you made a mistake at the middle marker, the landing report will print
out the consequences.
This only a small part of the capabilities of the JETSET
simulator. There are about 15 to 20 additional airports built in. It
is conceivable that you could fly all over the United States.
Remember though, this simulator is flown real-time. If it takes 6
hours to fly from New York to San Fransico in a real aircraft, it
will take you the same 6 hours flying the simulator.
