TRIP PLAN II USER'S GUIDE
To run the Trip Plan II program type TP2 and press <Enter>.
Trip Plan II is a time & distance calculator designed primarily to aid in
the scheduling of private and corporate aircraft.
Because it can estimate road miles as well as air miles, it can be very
helpful in planning vacation and other road trips.
It comes with a data base containing the geographical location of 4,000+
airports in the continental United States.
The only limit on the number of airports you can have in the data base is
the storage capacity of your computer. You may add additional locations to
to the system, however you will need some way of knowing the latitude and
longitude before you can enter them.
There are a number of publications available that will have this
information, and they usually can be found at your local airport.
THE MAIN MENU
After the program has been successfully loaded the following main menu
should be on your screen.
TRIP PLAN II - TIME & DISTANCE PROGRAM Ver 2.2
Copyright 1990 by Matrix Software Co. All Rights Reserved
PROGRAM SETTINGS Airports on File 4,004
Mileage calculations are based on Air Miles.
Speed and distance are Nautical Miles.
Speed is set to 205 Kts.
Layover time = 10 minutes.
Wind Direction = 230
Wind Speed = 25 Kts
Cost per Mile = 0.09
MAIN MENU CURRENT ITINERARY

Press <Esc> to Exit program
Enter selection >
You may select any of the menu items by number or by the first letter of the
selection.

You do not need to press enter after selecting a menu item. In fact while
you are using TP2, you will discover that the only time you need to press
the enter key is when your entry does not fill the entire field.
The first item on the menu is of course the main function of the program.
In order for TP2 to calculate distance and various other items of interest,
you have to tell it where you want to go.
When you select item 1 the trip itinerary screen will be displayed and the
current itinerary (if there is one) will be calculated and displayed. The
cursor should be at the next location for entering a city/airport name.
TP2 is a disk based data management system. Most of the data needed to make
calculations and display important information is stored in disk data files
and TP2 needs to find that data in order to do it's job.
Since it is a disk based system, the speed with which TP2 can find cities and
make calculations depends a lot on the computer you are using. Probably the
most noticeable effect on speed is a hard drive. TP2 works several times
faster on systems with hard drives than it does on a floppy drive system.
To help TP2 locate cities faster, we have kept them in alphabetical order in
their files. This gives the program the advantage of knowing where to look
for locations, rather than searching through the entire 4,000+ records.
This also allows you to find your desired cities without having to enter the
complete city/airport name.
For example, suppose you are looking for Houston Texas. You could type "hou"
and press <Enter> TP2 will find and display Houghton Lake MI.
The program tries to match whatever information you give it to the first
alphabetical occurrence in the file.
If there is no match, TP2 will get as close as it can and display that city.
When the city is displayed, it should appear brighter on your screen and a
message at the bottom of your screen will advise you to press enter to
select the displayed city, or to use the up or down arrows to scroll.
In this example, you could press the down arrow 4 time to scroll to the first
airport in houston which would be Houston Andrau.
Now lets try another method. With a city displayed and the message line at the
bottom of the screen telling you you can press the <Esc> key to Re-Enter the
city, press <Esc> to clear the field.
Type "houst" and press enter. Houston Andrau, Tx should be the first match to
your request and should be displayed bright on your screen.
Suppose you really wanted to go to Houston Hobby airport. Enter "houston h"
and, bingo, Houston Hobby, Tx is displayed for you.
Where there are more than one city and airport with the same name in the data
base (example Lawrence Muni, Ks and Lawrence Muni, Ma) then TP2 will use the
state for alphabetizing. In this case, Lawrence Ks would be found first.
Even though the state is used to sort the data files, you CAN NOT use it to
find locations. TP2 uses only the city/airport names in it's search. If you
include the state it will be treated as part of the city/airport name and
will not help you find the desired location.
Page (2)
Where you have two locations with the same city and airport name, you can
force TP2 to sort one ahead of the other by changing the name of one of them.
For example, if you want Lawrence Muni, Ma to be found before Lawrence Ks
then select item 2 at the main menu and edit Lawrence, Ma so that it reads,
Lawrence Muni, Ma.
Note that there are 2 spaces between the word Lawrence and Muni. The space
has a lower ASCII value than letters that might be used in an airport name
and will cause Lawrence Muni, Ma to be placed ahead of Lawrence Muni, Ks in
the file.
When using menu item 2, make sure you have a few minutes to spare. Any time
you add a new location to the system or edit the name of an existing one, it
will automatically be sorted to the proper location in the file.
This could take a few minutes depending on how much sorting and swapping has
to go on. The sorting is usually done in less than 2 min. on most computers.
Once you have your desired itinerary displayed, study the information to the
right of each city name.
The first column under RWY is the longest runway available at that airport.
The value has been rounded to the nearest 100' and then divided by 100. Add
two zero's when you read the number. For example the number 118 actually
represents a runway length of 11,800'.
Most of the airports in the data base have hard surface runways, there are
a few with other than hard surface and we have tried to indicate those by
putting an * in the last position of the City/Airport name field.
The next column (MDA) tells you if there is a published instrument approach
for the airport. If not, than it is a VFR airport and will have VFR in that
column.
If there is an instrument approach then the type of the first published
approach will be indicated by one of 10 letters. The one letter codes are as
follows:
V = VOR
N = NDB
L = Localizer
B = Localizer Back Course
D = VOR/DME
I = ILS
S = SDF
P = PAR or ASR
A = LDA
E = NDB/DME
Following the code will be a 2 or 3 digit number indicating the lowest
published decent allowed on the approach.
This number is always rounded UP to the nearest 10' and then divided by 10.
Add one zero to read the value. An ILS approach with a decision height of 246'
would be coded I25. A VOR/DME approach with an MDA of 1212' would be coded
D122.
The next column is distance and is not coded. If you are using air miles for
your calculations, you will find this figure
