We estimate that this will take 3 minutes to complete.
2 Detailed Explanation
NOTAM Filtering
You can create and
manage your own NOTAM filters instead of submitting requests
to NAVBLUE if
you want NOTAMs filtered from flight packages.
When using
filtering, keep in mind that you are filtering out the NOTAMs you want to exclude from your
reports. Put
simply, the logic should be that you are designating the
NOTAMS you do not want to
see,
rather
than those you
do.
NOTE: Please note that NOTAM filtering has broad consequences
within the N-Flight Planning application and
should not be
used lightly. Consequently, users must be assigned an
appropriate role in order to access the
functionality.
If you do not have the Maintenance or NOTAM filter options
available to you, you are likely missing
the appropriate
credentials, and must be assigned the correct role before you
can use the feature.
To request an
appropriate role, please open a ticket with NAVBLUE Support.
NOTAM Filtering
One of the features
of NOTAM filtering is the ability to assign an Auxiliary
Key to
a given aircraft.
The Auxiliary
Key is
an optional new data field added through FOMS 220 (Aircraft
Characteristics), and offers an
aircraft-level
of granularity when filtering NOTAMs.
The Auxiliary
Key is
an alphanumeric field, and is limited to 20 characters. Within
these parameters,
you can create
whatever key suits your needs. When you have designated an Auxiliary
Key,
only aircraft
that have been
assigned the key will use the specific NOTAM filters which reference it.
The new key is
found in the Maintenance >
Aircraft Characteristics page, under the Others tab.
Let's look at
how to use NOTAM Filtration, starting from the main screen.
Click
the Maintenance hyperlink.
HINT
If you do not see this option, you are lacking an appropriate role. Please open a ticket with NAVBLUE Support to correct this.
HINT
If you want to designate an Auxiliary Key, you do so from this option.
Click
the + New Filter button.
A Name for your filter.
An optional description of what the filter does.
A check box to make the filter active (checked) or leave it inactive (unchecked).
An optional Auxiliary Key to identify which aircraft are impacted.
The logic that comprises the filter.
Click
the Name input
field.
ATTENTION
If older filtering
logic has been ported over to the NOTAM Filtering feature, you
may see some of the special characters that are used to
construct the logic of the filter. These may seem unusual, but
are valid characters. One such example looks like this:
(^AO)|(^C[DGLMPT])|(^F[BCDGHLOPSTWZ])|(^I[UW])|(^LW)|(^M[ABGHKMNPUW])|(^N[ACFLNOX])|(^O[BL])|(^P[BEK])|(^R[DPR])|(^S[AFOPT])|(^W[DJPRSZ])|(AC$)|(C[MR]$)|(H[JKMNOPUWXZ]$)|(L[ABEFGKLS]$)
While not
required, you have the option of using these special characters
when crafting your own NOTAM filters. If you want to employ these
characters, the meaning of the special characters is:
Character Meaning
--------------------------------------------------------------------
^ Start of string
| OR
[ ] Any of the enclosed
characters
$ End of string
( ) Enclosure
HINT
A NOTAM filter is comprised of these conditions. Please read each function and the attention pop-up.
Click
the Text list
item.
From this list, you can choose the industry standard characteristic of the NOTAM upon which you want to base your filter.
This list is representative of the conditions that are available when constructing your NOTAMs. There are many conditions upon which you can base your filters, and you can add subconditions to each condition, which are then subordinate to the initial condition:
■ Location
■ Fir
■ Series
■ Number
■ Period
■ Issuer
■ Class
■ Text
■ Format
■ QCode
■ QCode23
■ QCode45
■ Upper and Lower Limit
■ Start and End Time
■ Age In Days.
ATTENTION
The operators which can be used on a filter differ based on the filter criteria. For example, the "Location" condition will not allow the "Less or Equal" operator. If an operator cannot be used with the selected filter, a warning message will pop up saying “Unable to save filter representation.”
For this example, we want to match a text string in the NOTAM, so we will leave this option as "Equal", and designate a value in the data field to the right.
Click
the Data input
field.
We've entered the text string "grass cutting" for you. This is the text the filter will look for in the contents of the NOTAM.
Now, let's add an additional condition.
Click
the Add Condition button.
Click
the Empty (-----) combo
box.
When you create additional conditions, you can choose how they relate to the other(s). You can choose if all of the conditions must be met by selecting AND, or you can choose if any condition is met by clicking OR. You can also choose NOT, which filters out anything that does not fit the criteria. For this example, we will accept the default AND value.
HINT
Additional conditions follow the same procedure to create as the one we just completed.
Click
the Age in Days list
item.
ATTENTION
Before you
continue, you must... (12pt)
ATTENTION
Before you
continue, you must... (12pt)
Click
the Data spin
button.
Enter 2 into
the Data field.
You can also include Sub-Conditions, that further delineate which NOTAMS to display based upon the filter.
Click
the Add Sub-Condition button.
Sub-conditions use
the same settings as Conditions.
For this
condition, let's designate a condition that results in a match
when it is NOT true.
Click
the NOT check
box.
Click
the Empty (------) combo
box.
Click
the Location list
item.
Click
the Data input
field.
Enter CYYZ into
the Data field.
HINT
Take a moment to
understand the filter we have just created. This filter will
prevent any NOTAMs with the folllowing characteristics:
- Where the
text includes "grass cutting" AND
- The age of
the NOTAM exceeds 2 days BUT NOT
-If the
location for the NOTAM is CYYZ (Toronto)
When you are
ready, let's enable the filter, and save it to the filter list.
Click
the Save button.
Click
the OK button.
Now, let's edit the filter we just created.
Click
the Edit button.
HINT
To keep the interface clean, filters that are not actively being created or edited have their logic settings hidden. You can still see the Name, Description, Auxiliary Key, and Active Status of the filter at a glance.
The logic settings for the filter open. From here, the process to edit is the same as to create.
Let's assume we no longer want to see items from CYYZ. We can delete this condition.
Click
the bottom Delete button.
We have deleted the condition, however the condition box remains. If there had been other sub-conditions, they would have been maintained. Since there was only one, we can safely delete the condition as well.
Click
the Delete button.
The whole condition is now deleted.
Let's add an Auxiliary Key to this filter.
Click
the Auxiliary Key input
field.
Enter B into
the Auxiliary Key field.
Now only aircraft with the "B" Auxiliary Key will be considered. Let's save the edited filter.
Click
the Save button.
Click
the OK button.
The changes are applied. But let's suppose you no longer want to use the filter. Deleting it is as simple as selecting a filter's respective Delete button.
Let's delete the filter we have been working with.
Click
the Delete button.
Click
the OK button.
The filter is deleted. Now you know how to create, edit, and delete NOTAM filters.
