NAVSIM - the Windows Navigation Calculator for Flight
Simulator pilots.
OPERATING INSTRUCTIONS
--------------------------------------------------------------
NAVSIM IS A SHAREWARE PROGRAM - all rights reserved
You may acquire the program for the purpose of establishing its
suitability. If you use it regularly, please become a
registered user by sending £15.00 (fifteen pounds sterling) or
equivalent value International Money Order to:
John Crabb

The above address is ALWAYS valid.

The shareware version of NAVSIM has a slightly restricted air
speed range. Whilst it is perfectly usable, most people like
to fly faster than its upper limit. Registered users will receive
a full working version with the top airspeed extended to six hundred
knots to cover jet simulations.

NAVSIM OPERATING INSTRUCTIONS
Description
NAVSIM is a program written to allow flight simulator pilots to
conduct pre-flight dead-reckoning navigation calculations and to
produce a flight log form on which to chart the progress of the
flight.This enables you to fly compass headings in any wind conditions
in the same way as the majority of private pilots would do. Even if
you habitually use radio navigation aids, NAVSIM will enable you to
calculate headings to counteract wind drift. Add realism to your
simulator flights!
NAVSIM is suitable for simulators using the original SubLogic/
Microsoft system of North and East coordinates. NAVSIM is a flight
simulation version of a program used by pilots of real aircraft
in flight planning. It runs under Microsoft Windows version 3.0
or later, and utilizes a wide range of convenient Windows
features. It is almost entirely mouse driven - the only typing
required is when entering descriptive details for printing on
the hard copy flight log form. NAVSIM offers the following
facilities:-
* convenient mouse driven entry of windspeed, wind
direction, true airspeed, fuel consumption rate and
magnetic variation
* convenient mouse driven entry of turning point coordinates for
up to twenty individual flight legs
* immediate, simultaneous calculation of distance, track,
magnetic heading, ground speed, time and fuel consumption for each leg
* automatic on-screen graphical plot of track lines; watch
your route build as you enter details
* compilation of complete on-screen summary of your route,
including total time, distance and fuel
* file-save facility to allow previous trips to be
recalled and updated for new in-flight conditions
* hard-copy printed output of completed flight log form
for use in the cockpit
* weight, volume, speed, temperature and distance
conversions
* calculation of true altitude, density altitude and true
airspeed
Program layout
NAVSIM presents four different work screens to the user. In
addition there is an introductory screen from which the initial
selection of a work screen is made. The screens are:-
* introductory screen and initial function selection
* route planning screen
* route summary screen
* conversions work screen
* altitude and speed correction work screen
The user may easily move from one screen to another, without
altering their content, by selecting the appropriate item from
a menu bar.
Using NAVSIM - an overview
The normal sequence of events in planning for a forthcoming
flight would be as follows:-
1. Decide the route you will be taking on your simulated flight
and note down the North and East coordinates of your departure and
destination airfields, as well as those of any intermediate turning
points. Set the "simulator grid offset" - see explanation later.
2. Set the wind conditions in which you wish to fly.
3. Load NAVSIM on to your PC and run by double-clicking the
icon. Full details for installing and running NAVSIM are given
at the end of the manual.
4. Select the "NAVIGATION" function by clicking on the
appropriate button in the INTRODUCTORY screen. The ROUTE ENTRY
screen will appear. This screen will allow you, simply and
easily, to enter the coordinates of your departure, turning and
destination points. You will also be able to set the wind speed and
direction, true airspeed, fuel consumption rate and magnetic
variation for each leg. The necessary magnetic heading to
achieve your desired track will be automatically calculated.
NAVSIM also automatically calculates ground speed, time and
fuel consumption for each leg.
As you enter the North and East coordinates, you will see your
routing vectors plotted on a graphical work pad. Hopefully, on
a round trip, you will have the satisfaction of seeing that
your final leg actually returns you to your point of departure!
5. From the navigation screen you may, if you wish, switch to
the SUMMARY screen to see a tabulated summary of the details
for each leg. Total trip distance, time and fuel consumption
are also reported on this screen. If you wish to alter any of
the in-flight conditions, wind speed, true air speed etc. this
may be done and the details for all legs will be automatically
adjusted to reflect the new conditions. You may exclude any
number of legs from this updating if you wish to allow for the
possibility that conditions may differ from leg to leg.
6. When your route details have all been entered you would
normally select the PRINT function. You will be invited to add
descriptive details for each leg which will be reproduced on
the printed flight log form. This is the only typing involved
in NAVSIM. When satisfied, select PRINT and a hard copy of
your flight log sheet will be printed on your printer. This log
is the same as that used by pilots to monitor progress of the flight.
It enables ETAs to be calculated.
7. Before quitting NAVSIM, select the FILE function and save
the details of your route to disk. If planning to repeat the
trip at a future date, saving the file will allow you to recall
the details and re-calculate headings etc. for changed flight
and meteorological conditions. You may not, however, alter the
distances or track bearings of any leg of a recalled file.
8. If, at any point, you wish to check on weight, distance,
speed or temperature equivalences; to calculate true airspeed
from indicated air speed or to determine true or density
altitude, simply select the appropriate work screen.
NAVSIM screen by screen
The following detailed instructions will guide you through
NAVSIM screen by screen. In case you are not totally familiar
with the operation of Windows, we define here two terms used
throughout the following sections:
"clicking" means moving the mouse to place the on-screen cursor
over the desired object and then pressing and releasing the
left mouse button.
"double-clicking" is the same except that the button is pressed
and released twice in moderately rapid succession.
INTRODUCTORY SCREEN
This is the self-explanatory menu screen which presents on
first activating NAVSIM. The user is presented with the choice
of three options:-
1. NAVIGATION.
Clicking once with the cursor arrow on this button will cause
the ROUTE ENTRY screen to be loaded. This would be the normal
entry to NAVSIM. Using this screen you can enter the route of
your proposed trip. You can also access the ROUTE SUMMARY
screen from the ROUTE ENTRY screen.
2. CONVERSIONS
Clicking the mouse once with the cursor arrow on this button
will load the CONVERSIONS work screen. This screen allows you
to perform a number of volume, weight, distance, speed and
temperature conversions.
3. ALTITUDES/ SPEEDS
Clicking on this button loads the ALTITUDES/ SPEEDS work
screen. This enables you to perform some of the less common
correction calculations such as calculating True Air Speed from
Indicated Air Speed (rectified).
ROUTE ENTRY SCREEN
The ROUTE ENTRY SCREEN may be immediately recognized by the
