About Aviation Planning Tools

AVIATION SOFTWARE TOOLS 1988

Colin Marshall, Ian Green Mathon Road, Malvern Worcestershire, WR14 4BU

I was given a copy of Pilots Companion ages ago to evaluate. It didn't come with a manual, I had no idea of what it did and so it has been dormant Pilot Companion and the manual in 1989 to evaluate. Did anyone use it? Was it well marketed? I never heard of it again.

The company was based in Malvern, their address was P.E.I. P.O. Box 4 MALVERN Worcs., but they are no longer there. So here is your chance to trawl with me through the commands and get an understanding what this program did.

The requirements to run this program on the Z88 is at least 128K RAM in slot 1 and the Pilots Companion EPROM to be in slot 3. The EPROM must not be moved whilst using the program as the software checks that it is still there occasionally.

Pilots Companion is started initially by giving the Z88 a Hard Reset, with the Pilots Companion's EPROM card in slot 3. The boot.cli file starts a chain of commands that sets  :RAM.1 as the Default Device, fetches all the files from the 
EPROM card and starts running the program. To leave the program press the Image Removed key.

If Pilot Companion has already been used it will appear in the SUSPENDED ACTIVITIES area of the index from which it can be re-selected using the cursor bar. 

Image Removed

When it is running, when in the INDEX it will be shown as a suspended activity with the file name used as YOUR REF.  There can only be one Z88 Data Organiser application running.

Image AddedPre-Flight Requirements

Image Added

The requirements to run this program on the Z88 is at least 128K RAM in slot 1 and the Pilots Companion EPROM to be in slot 3. The EPROM may be moved after running the program.

For best results, (if you have nothing running on the Z88)  Pilots Companion can bestarted initially by giving the Z88 a Hard Reset, with the Pilots Companion's EPROM card in slot 3. The boot.cli file starts a chain of commands that sets  :RAM.1 as the Default Device, fetches all the files from the EPROM card and starts running the program. This ensures that the Z88 is at a known state. To leave the program press the Image Added key. Alternatively use the following methods depending what state the Z88 is in.

1. If Pilots Companion is already shown in the index list of running Applications.(Press Image Added to view). Position the curaor over the name and press Image Added.
    
2. If Pilot Companion has already been used it will appear in the SUSPENDED ACTIVITIES area of the index from which it can be re-selected using the cursor bar. 

   Image Added

   When it is running, when in the INDEX it will be shown as a suspended activity with the file name used as YOUR REF.  There can only be one Pilots Companion application running

   Position the cursor on the name & press Image Added
   
   

3. Pilot Companion files are resident in the computer having been loaded from the plug in EPROM cartridge but not shown in the index list of running applications.(Press Image Added F to view Files - the main program is called 'way2').  Enter BBC BASIC and type RUN "WAY2"

   Note
   Note that if the program returns to the BASIC prompt at any time then typing RUN will start it again.

   
   

4. Pilots Companion is on EPROM and your computer is in use
   
   A 

   Note
   Note the following procedure will delete any running applications so first save any required information to files.

   Plug the Pilots Companion EPROM into slot 3 on the Z88. Ensure Slot 1 has at least 128K of RAM Plugged in..'
   Press, the Diamond key (Image Added) and then type PURGE
   The required files will, now be loaded from EPROM this will take a little time finishing with the Pilots Companion first menu being displayed.
   The EPROM may now be removed and from now on methods 2 or 3 above can be used to start the program. Most pilots will want to leave the Pilots Companion resident as updates to preserve temporary updates.
   
   B Alternatively fetch the file boot.cli from the Pilots Companion EPROM and Execute the file. This will then load all required files and start the program.
    

5. Pilots Companion is on EPROM and your computer is new.
   
   Plug the pilots companion EPROM into slot 3 on the Z88. Plug 128K RAM pack into slot 1 on the Z88.
   Press the  Diamond key (Image Added), then type PURGE (This is the same as pressing the reset button),

If required all files from EPROM could be copied-manually then 3 above actioned.

Image AddedG. A Brief description of the General function of the Flight plan

A plan is developed beginning with the new plan option (opening menu option 2).

Once this plan has been completed it becomes the current plan (option 1 of the opening menu). Actions on the current plan are taken from this option i.e. to

1. re-run the plan and maybe 
2. change wind, airspeed etc. 
3. to print, 
4. to run the return trip, 
5. or to save this current plan.

Old plans saved from previous use may be recalled and become the current plan. These old plans are retrieved using option 3 of the opening menu.

A most useful feature of this program is the ability to restart at any time this is achieved by pressing the Image Added key on the top left hand corner. (Commonly known as the OH! shit button). This allows you to play with features ad hoc and and recover at any time. The best way to find out how it works is to keep pushing buttons - it’s really very easy.

Once you find out how easy it is to generate a plan you will never want to revert to the old manual planning methods.

Image AddedH. More Detail on NEW PLAN

- (select option 2 on the opening menu). The following appears on the display

Image Added

The above message is displayed on the screen. Ensure that Image Added is selected then type in the full name of the airfield from which you wish to begin your journey. Press the Image Added key and the computer will then begin to search for the place name you have typed in. When the place name has been found the message requesting you to enter the next point in your flight is displayed i.e.

ENTER WAYPOINT NO.(1) ?

Remember you can press Image Added to restart everything if you wish this will return to the opening menu.

VOR HON

The space between VOR and the ident HON must be included. For an NDB use the same format i.e.

NDB SVN

ENTER WAYPOINT NO (1) ?

This is displayed if the search for your place name was successful. Now type in your next point in the journey i.e. the first destination point. Press Image Addedand the search for this place will begin

If the search for WAYPOINT NO.1 was successful then the message

ENTER WAYPOINT NO.2 ? 

will be displayed.

To end your plan press Image Added at this point or continue the plan by typing in more waypoints as described above. Pressing Image Added at the ENTER WAYPOINT NO. message will indicate there are no more points.

The plan routing is now displayed giving the Latitude & Longitude of each place along with its It letter identifier, (if there is-no identifier then the first 4 letters of the name are used in the case of airfields.) You may hold the display by pressing Image Added to inspect the plan and verify the information provided is correct. To continue the program press Image Added again.

Image Added

In either case the details menu is now displayed as follows :-

ARE THESE CORRECT  ? (Y)  ?

If the details are correct then press Image Added (or Y and press Image Added)

The details will then be used as given to generate the plan. From this point the whole flight plan is produced automatically the displays running through each stage without further manual input. If you wish to hold the display at a point then press Image Added - the screen will now be held until Image Added is pressed again.

The final screen after the last Waypoint and destination are displayed gives details used to produce this plan along with total distance, total time and total fuel used. This display may also be held using Image Added as described. The program returns to the opening menu after this display.

The plan you have just completed now becomes the current plan and if option 1 on the opening menu is selected then the current plan menu is displayed This gives options to display the current plan again giving you the opportunity to change the details -wind etc. required or simply repeat the plan again.

Other options are to produce the return trip plan -this is generated automatically by selecting this option. Printing the plan to a paper printout can be from this menu. The plan may also be saved for future recall here.

Further operations on the DETAILS menu

If the details as shown on the display at the point indicated above were not correct then type N and press Image Added. The alter details menu is now displayed.

Image Added

The values shown inside the brackets at each menu line are the default values and pressing Image Added will give this value. To alter a value simply type in the required number followed by Image Added. Follow the instructions as given in the display.

Now follows a description of the display.

1. The display is split into 2 columns. The left hand column contains the highest priority information the topmost being your required heading. 
   The right hand column contains lower priority information but will still be useful en-route.
2. The following words appear on this display.

Image Added

The left hand column contains:

The right hand column contains :

Image Added

At the end of the plan-the following are displayed the left hand columns showing the values of windspeed and direction, airspeed, fuel consumption and magnetic variation used in the current plan computations.

The right hand side columns give totals of Distance, time and fuel used for the complete trip. The printed version of the plan is also timed and, dated at the time of printing.

9) Returns automatically to the opening menu.

Two more functions are selected here.

Image Added5 AIRFIELD DATA BASES

There are 3 choices. The first two asks

Image Added

Image Added1 ADD a NEW location

1. ADD a NEW location
This selects the menu:

Image AddedDefining Waypoints

There are two ways of defining waypoints.

Image Added

1. Use latitude & longitude ?

The sequence entered requests firstly the name of the location you wish to add to the data base. This should he a unique name you wish to refer to or in the case of a vor or ndh use the ident code. You are next requested to enter the latitude of the location. It is necessary to use the format indicated (123456N i.e. degrees minutes seconds first letter of North or South as appropriate) otherwise it is not possible to continue with the: process.

Next longitude is requested in the same format. This may have two or three digits in the degrees element and the first letter of East or West as appropriate.

 Finally the IDENT CODE is requested. There is no fixed format for this but the inbuilt data bases use the following convention: 

• If one exists, use the 4 letter airfield ident code
• If no code exists use the first 4 letters of the name
• If it is a vor or ndb give the frequency

Data required to add a new location are:-

• NEW WAYPOINT Name
• Latitude  (123456N)
• Longitude  (123456W)
• Ident (ABCD)

1 Use Latitudes & Longitudes? - Example

The positions of Airfields for example are given in Latitudes & Longitudes. These are found in the Aerodromes published in the UK AIP.

Local VORs are given on main Airfield sites.

** BRIZE NORTON (ENR 2.1)

2 Use Relative Locations? - Example

When using relative locations, to describe the waypoint, the following information is required.

• A KNOWN LOCATION that is in the database is chosen as a start point.
• The TRUE BEARING from the KNOWN LOCATION in DEGREES TRUE
• The DISTANCE between the WAYPOINT and the KNOWN LOCATION (in naut,mls)
• A UNIQUE NAME for this waypoint.
• An IDENT CODE for this WAYPOINT

The result is given in Latitudes & Longitudes and give a unique name. The example below shows an abstract location 10 nM, 30 degrees from Oxford.

Image Added

Image Added

Image Added2 UPDATE an EXISTING location

Data required to update an existing location are the same as above:-

• NEW WAYPOINT Name
• Latitude  (123456N)
• Longitude  (123456W)
• Ident (ABCD)

This is the option used when the location already exists in the data base but some of its information has changed e.g. location or frequency etc. The subsequent menu selected is the same as for the ADD option If two entries with the same location name are made under UPDATE option the last one entered is used by the program i.e the most current entry is utilised. If two entries with the same location name are inadvertently made under the ADD option the later entry will not be accessed.

Image Added3 Advanced user options

Primarily intended for the more computer literate user the options called here should be used with care in particular the create option destroys any existing content of the file being created.

This following menu is displayed:

Image Added

Image Added4 SHOW a Data base  ?

This option will display the content of a data base file.
Give the three letter file name and the content will be cycled through.

Image Added5 APPEND to existing database  ?

This option allows further locations to be added to the end of any data base file. Follow the instructions given these are as for the ADDITIONS option which In itself would be more normally used.

Name of Database to modify? (WAV). Select a database to use.

1 Use Latitude & Longitude?

See Defining Waypoints for more details.

2 Use Relative Location?

See Defining Waypoints for more details.

I HAVE NOT MANAGED TO MAKE THIS WORK.

Image Added6 CREATE a New Data Base  ?

This option allows the creation of independent data bases allowing the user to keep personalised data. A three letter file name must be used.

A location is then later accessed by first typing these three letters followed by a space and then the location name. Note that if a file name already exists the original contents will be lost using this option.

Example - Use the suggested file name.
