Why Spine? Top
Spine stands for "Soaring Pilot's Intelligent NOTAMs Editor".
Who's it for? Top
While, as its name suggests, Spine is mainly aimed at glider pilots, it can
also be used by private GA pilots. Settings can be changed to filter NOTAMs for Gliding,
GA VFR or GA IFR.
Currently, due to the availability of source information,
the program can only be used in the United Kingdom.
What's it for? Top
NOTAMs as downloaded from the Internet contain a lot of information that is not
relevant, especially to glider pilots. Neither are they usually sorted into
a convenient order.
Spine helps you to edit NOTAMs and discard the irrelevant ones, and also sorts the
output into a usable form. You can also restrict the output to a specific area,
for example by setting a maximum distance from your home airfield.
Summary of features Top
- Automatic download of Pre-flight Information Bulletins (PIB) from NATS web site.
- Ability to process user-specified NOTAM briefs saved from NATS web site. These have
more information and are more up-to-date than PIBs.
- Automatic removal of non-relevant items.
(but user has ultimate responsibility to check results).
- Option to set range, such as distance from a specified location.
(The location can selected from a list of BGA turning points or ICAO airports.)
- Many sorting options, including by position and date, or by distance and bearing from
a specified location.
- Browse feature for quick review and selection of NOTAMs to be included.
- Plotting of airspace, NOTAMs and task in a graphic window.
- Formatted output to printer, HTML file, OpenAir format file
(for XCSoar or Winpilot), or Tim Newport-Peace format file (for Glide Navigator II
- Quick checklist for ease of use.
- Built-in coordinate lookup for any 5-letter reporting point (such as HAZEL, REXAM etc.).
- Automatic program and database updates when connected to the Internet.
Minimum requirements Top
System with Pentium-compatible processor running MS Windows XP or later. A minimum
screen resolution of 1024x768 is recommended, due to the size of the main dialog.
Installation and Removal Top
Just double-click on the self-installing image you downloaded and
follow the instructions to install the program.
To remove the program from your computer, go to Programs (Windows 7/Vista) or Add/Remove Programs (XP)
in Control Panel and click on the Spine entry.
Version history Top
- A danger area referenced in a Notam has been plotted as an enclosing circle since V6.5, instead of the shape of the area. This is now fixed.
In addition, multiple danger areas referenced in the same Notam are now handled properly.
- Notam popups did not work properly if the Notam consisted of more than one area.
- Altitudes of FL030 and below are now shown as FT AMSL.
- Fixed a bug with plotting complex shapes.
- Fixed a potential problem when downloading Notams from the mobile network.
- Updates to the Q line decode file to add new subjects and conditions, and to allow Air Navigation Route to be plotted.
- Improved accuracy of coordinates in a small number of cases where seconds of arc were not being taken into account.
- Improved processing of coordinates in text part of Notam, so more actual shapes can be plotted, instead of default circles.
- A couple of fixes to data files (already issued): Coordinates for EGCT Tilstock corrected and a
typo in Strangford CTA-4 fixed in Airspace.
- Distance to a FIR-wide NOTAM (radius > 300NM) was being calculated as the distance to the centre of the circle.
This should be zero, since the point is obviously inside the circle.
- Airspace under NOTAMs is now appended to the info popup, and stacked airspace is listed in priority order
(highest priority first).
- Unclosed areas in NOTAMs are no longer plotted. This prevents random lines being drawn where coordinates
mentioned in the text are unconnected. This obviously does not apply to linear route NOTAMs, such as formation flights.
- More closed areas in the text, which were previously overlooked, are now discovered.
- The abbreviation for NOTAM classification "Exercise" (QWE) has been changed from MILEX to EXERCISE, since it's not
- The help has been updated to show recent changes.
- Two buttons have been added to the main dialog to simplify access to a couple of features:
- Displaying the latest server message again (this was previously hidden away on the User tab
of the Settings dialog).
- Visiting my web site.
- The Help menu item on the Plot window had stopped working and is now fixed.
- The appearance of controls (buttons etc.) had reverted to an older version (symptomised by flat, square
cornered buttons). This has now been fixed.
- This is an urgent update to prevent auto-deletion of NOTAMs with a radius > 300NM. This was deleting some
NOTAMs relating to Olympic airspace.
- This is mainly a technical release to upgrade from an unsupported legacy version of the compiler to the current platform.
- Data files are now stored in the correct location, to enable updates without resorting to a Microsoft hack
which is only there to support legacy code ("virtualisation").
- It is no longer possible to download Mauve AICs and AIP supplements directly, so a message box has been added to
explain the situation.
- Fixed a bug where some NOTAMs could be missed in output OpenAir/TNP format files.
- Mauve AICs have moved to a different server so the URL has been updated to reflect this.
(Unfortunately access to these pdf files is currently restricted and the download feature
doesn't work. We are hoping this restriction will be lifted in the future.)
- Migrated to new web host, which necessitated changes to embedded URLs. That's all.
- Fixes a problem where due to format changes, a reference in the NOTAM text to a Mauve AIC was no
- The URLs for both AICs and Supplementary AIPs have changed and have been updated.
- In addition to Mauve AICs, Yellow, Pink and Green AICs are now handled.
- Parachute Drop Zones are now treated as a special airspace type. These are plotted as a red
outlined circle. Previously they were either lumped in with Danger Areas or Prohibited areas.
- A turning point info bar is now included at the top of the plot window. This shows details of the point
nearest to the cursor. You can choose any combination of BGA turning points, ICAO airports, Reporting
points and Navigation aids should you choose to display these on the plot. Type combinations can be selected
from the flyout on the View menu.
- Popup information is now displayed irrespective of which cursor (crosshair, zoom, pan) is in use.
Previously popups were restricted unnecessarily to the crosshair cursor.
- Changes to support changed BGA Turning Point file format and 4-character codes.
- The full name (where available) for danger areas is now displayed in popups in the plot window.
Previously only the "Dnnn" part was shown.
- A couple of new Subject designations have been added to the Q line definition file, and Help
has been updated to reflect this.
- In addition, when the Q line definition file is updated, filter settings are reset to their defaults
to incorporate any changes.
- There have been minor changes to task editing.
- Fixes a problem caused by a change in format of NOTAMs downloaded from AIS web site (active dates/times),
which caused NOTAMs not to be plotted.
- Added "point and click" task editing.
- Now shows task information (total distance, leg length etc.) when hovering over a task leg.
- Added mouse wheel zoom in/out.
- Added pan sensitivity control to make pan tool more responsive.
- Changes to linear routes: where several NOTAMs overlap, a linear route is now treated as "smallest", so
that it pops up at the top of the list.
- BGA turning points placed more accurately on plot. Previously, the location was rounded to the nearest
- Airport was not being shown for downloaded NOTAMs.
- More fixes for linear routes (e.g. formation flights). Calculation of minimum distance from airfield
was wrong in some cases, and popup information didn't work properly.
- NOTAMs downloaded from AIS web site were not plotted because active times were parsed incorrectly.
- User preference for Reporting Point/VOR display on plot was not saved.
- Incorrect URL for AIP Supplements fixed.
- Fix the plot of linear routes (for example, formation flights) so that the last coordinate
is not connected back to the first, which gives misleading information.
- One-click download of AIP Supplement if referenced in NOTAM (similar feature to Mauve AIC download).
- Fix for internet connection via mobile operator. Optimisation of transmission which removes newlines in
HTML code was causing parsing to fail. Code has been rewritten to parse HTML correctly.
- The main dialog layout has been improved to make controls more accessible.
- Closable panel with current NOTAM details added on left of Plot window.
- NOTAM info popups in the Plot window are now ordered from smallest to largest
radius, so that when NOTAMs overlap, it is no longer necessary to click
- One-click download of Mauve AIC if referenced in NOTAM.
- Fix for a problem where the Active From or Until times were marked as estimated.
These were giving an error. Now they are processed correctly, and shown with
'(Est.)' after them.
- Nicer font used in all dialogs.
- Fix for Vista. It is no longer necessary to run Spine as administrator for
data file updates to work.
- Add Lat/Long graticule to the Plot window. This feature may optionally be turned off
by the user.
- Fix a problem which resulted from a change to the downloaded PIB format.
- Fix lower and upper bound display.
- Fix a bug with distance calculations from home airfield to non-circular NOTAM areas,
which could also cause the program to crash for some, but not all, home airfield settings.
- Add task plotting facility.
- Delete NOTAMs which have Aerodrome scope only, when Aerodrome NOTAMs are not requested.
- Add button to give quick access to AIS login page.
- Change the way airspace is processed so that danger areas not normally displayed can be
plotted with the correct shape when activated by NOTAM.
- Add facility to parse user-saved NOTAMs from NATS web site, as well as PIBs.
- Process NOTAM Scope (from Q-line) correctly, and show on display and printed output.
Add view selection based on Scope.
- Move some controls on to tabs in main dialog to reduce clutter.
- Plot airspace layers in correct order, so high-priority airspace (such as Prohibited area)
doesn't get lost under lower priority stuff.
- When NOTAM information pops up on plot, main dialog now switches to that NOTAM.
- Fix bug that stopped a danger area mentioned in the text being found in the airspace file.
- Help file updated in line with changes.
- Fix page breaking on print out.
- Do sanity check on coordinates pulled from free text.
- Don't attempt to plot areas that specify arcs (maybe in future).
- On NOTAM popups in Plot Window, stop airport from an earlier NOTAM
"leaking" into a NOTAM that doesn't have one.
- Put separator between distinct areas in coordinate list.
- Include latest airspace.
- Include updated list of reporting points.
- Fixed a serious bug causing NOTAMs to be missed.
- Process schedule information.
- Fixed a bug in parsing the new format.
- Airport code/name (where available) was not being displayed.
- Fixed formatting problem in Turning Points file.
- Included latest airspace file in package.
- Updated to use the revised AIS file formats.
- Fixed date range handling when both FIRs are selected.
- Only output plotted NOTAMs to OpenAir/TNP files.
- Added file output in Tim Newport-Peace format to support Glide Navigator II
and SoaringPilot PDA software.
- Fixes a problem in the airspace parser.
- Includes latest airspace file in package (UK.AIR V2006 B).
- In some cases, spurious extra lines were being drawn when plotting NOTAMs.
- Fixes for automatic updates.
- Fixes an infinite loop if Checklist buttons were used with Settings already open.
- Can now cycle through info for multiple NOTAMs at same point on plot.
- Date selector moved from Output Settings to main dialog. It now
applies to viewing as well as printing or file output (Only
NOTAMs between the chosen dates and times are shown).
- Any changes made in the main dialog (settings, dates) are now reflected
immediately in the plot window if showing (previously only a new plot showed these
- If dates are changed in the plot window, they are also changed in the
main dialog (so dates can be changed from either).
- "Don't plot" button now applies to the plot
window as well as OpenAir output.
- Printing options check removed from Checklist (no longer needed).
- Revised which items can/cannot be plotted in Q-line decode file.
Changes to plot feature:
- Added date selector.
- Added popup information for airspace.
- Improved appearance of popup window.
- Some plot preferences now saved.
- Fixed focus problems which caused pan to stop working.
- Fixed cursor refresh (current cursor was sometimes lost).
- Arrow cursor changed to crosshair.
- Enhanced coastline.
- Addition of plot feature.
- More accurate processing of NOTAMs with complex shapes (polygons),
including calculation of minimum distance from home airfield.
- Fixes serious problem with detection of "all-night" NOTAMs. One-day
NOTAMs starting before dawn and ending after sunset were being
auto-deleted if this option was selected.
- Fixes bug with linear bounds (NOTAMs restricted by lines of latitude
and longitude). Radius of influence was being ignored, so a NOTAM with
a centre outside the bound, but penetrating the included area was deleted
as out of range.
- When saving files, a suggested file name based on the current date
(yyyymmdd) is preset in the dialog.
- Major changes to implement 'Q' line handling.
- New Filter settings page replaces Auto-delete.
- Adds GA VFR and IFR filter modes (as well as Gliding).
- Optionally includes Aerodrome as well as En-route NOTAMs.
- Individual NOTAMs can be manually excluded from OpenAir plot.
- Sunrise/sunset times calculated so night-only NOTAMs can be auto-deleted.
- Sunset time for home airfield now shown on output.
- Fixes to run properly from non-privileged accounts.
- Fixes for Windows 98 users.
- Fixes Airfield settings Reset button.
- Easier selection in Find Reference dialog.
- Headings added to Coordinate List dialog.
- Warns if cancelling Settings when changes have been made.
- Always prints distance from origin if defined (previously user choice).
- Checks integrity of installation on startup (missing data files).
- This is a quick fix for the addition of the 'Q' line to the source PIBs which broke
Spine. The 'Q' line will be used properly in a future version.
- Adds facility to set a proxy for internet access.
- Fixes a bug which caused an update request for two data files each time
Spine was run.
- Technical update to simplify future addition of NOTAM types and type rules.
- Data files updated (Airports and Name Code Designators [Reporting Points]).
- In Auto-delete settings, types are now selected from a list box instead of by
individual check boxes (part of technical update).
- In Find Reference dialog, double-clicking an entry now does the same as a
single-click select followed by OK.
- Improved error checking and warnings in Settings and Quick Setup.
- Bugfixes and additions to Type classification.
- Improvements and fixes to OpenAir format to display areas correctly.
- NOTAMs in the OpenAir file are defined as virtual Class E airspace, which is
otherwise unused. This must be enabled in Winpilot's airspace settings to have
the NOTAMs displayed.
- Detection of a NOTAM's radius of influence improved (some were being missed due
to unusual formatting of the text).
- Search by reference feature added.
- Help updated and index improved.
- Added option to save NOTAMs in OpenAir format file for upload to Winpilot etc.
- NOTAM reference included on printed output.
- Fixed bug which could cause incorrect validity times to be shown on printed
output and on main dialog.
- Fix bug introduced in V2.0 which excluded NOTAMs starting and finishing on
selected day when selecting single-day output.
- Beta version to test new program download method. (Not generally released.)
- Start/finish time was omitted from output page header.
- New version package now downloaded from program instead of relying on browser,
which caused problems for some.
- Change to method of downloading NOTAMs. No longer requires an AIS user account.
- Quick Setup feature for new users. Also invoked for existing users, when upgrading
if new information is needed.
