The NOTAM Filtration capabilities of N-FP allow you to create and manage your own NOTAM filters to manage which NOTAMs appear in flight packages.
Note: 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.
Accessing NOTAM Filter
The NOTAM filer settings are found through the Maintenance screen. Users with appropriate assigned roles can access the filter settings through an option at the top right of the screen.
Basic screen layout
The NOTAM Filter screen lists the existing filters and has the following attributes:
Adding and Editing a filter
When adding a new filter or editing an existing one, the filter opens to reveal the logic used when applying it. You must provide the logic based upon the criteria.
Note: When you are adding or editing a filter, you cannot perform any actions on any other filters until you Save or Cancel your work on the current filter.
There are many conditions upon which you can base your filters, and you can add sub-conditions 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
Each filter supports operations NOT, AND, and OR:
NOT – anything that does not fit the criteria will be filtered
AND – anything that meets all criteria will be filtered
OR – anything that meets at least one criterion will be filtered
Note: The operators which can be used on a filter differ based on the filter criteria.
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.”

Special Characters
Special characters can be used when crafting a filter. If you see these as you are creating your own filters, they are typically the result of porting old filtering logic to the new NOTAM Filter function.
One example of such a filter may be:
(^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]$)|(L[ABEFGKLS]$)
The special characters used in creating such a filter are:
Deleting a filter
To delete a filter, simply click the Delete button associated with the filter, found as part of each listed filter.
A dialog box displays, asking you to confirm the deletion.
Clicking OK deletes the filter.
Note: The appearance of the Delete dialog varies by browser, yet the result is the same. However, if you use the Firefox browser, a checkbox for “Prevent this page from creating further dialogs” may appear under the Delete confirmation. Do not select this check box. You will not be able to delete any further NOTAMs until settings are reset in the browser.
