Definitions

  • the present disclosure relates generally to Notice to Airmen (NOTAM), and, more particularly, to enhancing NOTAM.
  • NOTAM Notice to Airmen
  • NOTAM In aviation, a NOTAM is a notice containing information that is essential to personnel concerned with flight operations. NOTAMs concern the establishment, condition, or change of an entity or action (e.g., vehicle, facility, service, procedure, or hazard) in the airspace or concerned with airspace operations.
  • entity or action e.g., vehicle, facility, service, procedure, or hazard
  • NOTAMs consist almost entirely of abbreviations which make them difficult for humans to read and understand quickly.
  • An example of a NOTAM is "SVC TWR CLSD MON-SUN 0100-1100, CLASS D SVC NOT AVBL CTC JACKSONVILLE APP AT 121.725.”
  • a reader of a NOTAM may miss important information, which can occasionally create a safety hazard for flights.
  • NOTAMS typically received may be numerous, further increasing the chance of missing important information. For example, there may be hundreds of NOTAMs a pilot may need to scan through of which, for instance, maybe 5% pertain to their planned route. Further, such an operation may require a large portion of the pilot's attention, reducing the amount of attention a pilot may spend on other important tasks. As pilot operations move towards single pilot operations over dual-pilot operations, the attention demands of the pilot may increase.
  • a system and method for generating an enhanced set of NOTAMs include converting one or more abbreviated terms of a NOTAM text of the NOTAM into one or more respective expanded terms.
  • the system and method include applying a set of capitalization rules to the NOTAM text.
  • the system and method include emphasizing a portion of each word of the NOTAM text based on one or more emphasizing rules, where words are terms with only letters.
  • the system and method include directing at least a portion of the enhanced set of NOTAMs to be at least one of displayed via a display or physically printed by a printer.
  • a letter following a reference numeral is intended to reference an embodiment of the feature or element that may be similar, but not necessarily identical, to a previously described element or feature bearing the same reference numeral (e.g., 1, 1a, 1b).
  • reference numeral e.g. 1, 1a, 1b
  • Such shorthand notations are used for purposes of convenience only and should not be construed to limit the disclosure in any way unless expressly stated to the contrary.
  • any reference to “embodiments”, “in embodiments”, “one embodiment” or “some embodiments” means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment disclosed herein.
  • the appearances of the phrase “in some embodiments” in various places in the specification are not necessarily all referring to the same embodiment, and embodiments may include one or more of the features expressly described or inherently present herein, or any combination or sub-combination of two or more such features, along with any other features which may not necessarily be expressly described or inherently present in the instant disclosure.
  • FIGS. 1A-4B generally illustrate a system and method for use with NOTAMs.
  • At least some embodiments of the inventive concepts disclosed herein are directed to displaying an enhanced set of NOTAMs for increased readability, including filtering out irrelevant NOTAMs, and thereby decreasing the amount of time a user may need to spend reading NOTAMs.
  • understandability and speed of reading NOTAMs may be improved, thereby increasing safety, efficiency, and attention bandwidth of users. This may free up valuable attention, but in a manner that still allows for user-monitoring of NOTAMs at a high level of understanding of important information.
  • NOTAMs there may be hundreds of NOTAMs a pilot may need to scan through of which, for instance, maybe 5% pertain to their planned route. As a result, sometimes a reader of a NOTAM may miss important information, which can occasionally create a safety hazard for flights.

  • a portion of each word of the NOTAM text may be emphasized based on one or more emphasizing rules.
  • emphasizing may include changing a graphical quality of one or more characters (e.g., letters, numbers) of the NOTAM text such as, but not limited to, a text line thickness (e.g., being bolded), a text color, a highlighting (e.g., changing text background), or the like.
  • the one or more emphasizing rules includes bolding a portion of each word of the NOTAM text.
  • the bolding may be determined by a set of bolding rules.
  • bolding the words may include bolding a first letter of each word.
  • words are generally terms (e.g., sets of characters separated by spaces, commas, and the like) that include only letters (rather than numbers).
  • “defined” is a word, but "1100UTC", and "500” are not words.
  • bolding the words may include bolding the first two letters of words having at least two letters. For example, if both rules above were used, then "a” would be completed bolded, and the letters "de” of "defined” would be bolded.
  • FIG. 5 illustrates a NOTAM before being enhanced 502 and an enhanced NOTAM 504, in accordance with one or more embodiments of the present disclosure.
  • the NOTAM before being enhanced 502 reads, "SVC TWR CLSD MON-SUN 0100-1100, CLASS D SVC NOT AVBL CTC JACKSONVILLE APP AT 121.725".
  • the NOTAM before being enhanced 502 may be used to generate a counterpart-an enhanced NOTAM 504.
  • the enhanced NOTAM 504 reads, " T he a ir traf fic con trol tow er a t Cec il air port (VQQ) h as cha nged ho urs o f oper ation a nd i s n ow clo sed bet ween 0100UTC a nd 1100UTC da ily.
  • a graphical indication of each NOTAM may be changed from being in an unread state to being in a read state based on a user input associated with the NOTAM.
  • each displayed NOTAM may be configured (by software stored on memory 106) to be displayed in an unread state.
  • a user may touch one or more areas of a touchscreen of a display 112. Such user input may indicate that one or more of the NOTAMs are "read" (e.g., viewed) by the user.
  • touching a graphical representation of the NOTAM, a checkbox or the like associated with the NOTAM, or a "clear all” or similar button/option may be configured to cause one or more (e.g., all) of the displayed NOTAMs to be changed from an "unread" state to a "read” state.
  • a user may keep track of which NOTAMs they have already viewed and which NOTAMs they haven't, such as newly added NOTAMs.
  • the unread state and the read state may be indicated by any graphical method known in the art. For example, a checkbox near the NOTAM may be empty in an unread state and checked in the read state.
  • a darker (e.g., black) font may be used for unread NOTAMs and a lighter (e.g., grayer) font may be used for read NOTAMs.
  • a vertical line or box e.g., thin vertical line
  • such a line/box may be removed and replaced with background in a read state.
  • additional NOTAMs may be received.
  • additional NOTAMs may be acquired in the same or different way as the NOTAMs acquired in step 202.
  • at least a portion of the additional NOTAMs may be enhanced to generate additional enhanced NOTAMs.
  • the enhancing may be the same, similar, or different to the enhancing of step 208.
  • at least a portion of the additional enhanced NOTAMs are directed to be displayed via the display 112.
  • the additional enhanced NOTAMs may be displayed in an unread state.
  • the additional enhanced NOTAMs may be prioritized (vertically ordered) based on their relevancy value compared to the relevancy value of enhanced NOTAMs displayed in step 210.
  • FIG. 4A illustrates a conceptual map of geographic locations 404 of unfiltered NOTAMs and geographic flight data 402 of a flight plan, in accordance with one or more embodiments of the present disclosure. As shown, many NOTAMs 404 may be received by a system 138, even ones that are far away and irrelevant to a flight plan.
  • FIG. 4B illustrates a conceptual map of geographic locations 404 of filtered NOTAMs and geographic flight data 402 of a flight plan, in accordance with one or more embodiments of the present disclosure.
  • the NOTAMs 404 of FIG. 4A may be assigned a relevancy value according to step 206 in accordance with one or more embodiments. For instance, such a relevancy value may be used to filter out irrelevant NOTAMs. As shown, far fewer NOTAMs are shown in FIG. 4B .
  • the present system and method may significantly improve understandability and speed of reading NOTAMs, thereby increasing safety of a flight, efficiency in keeping track of NOTAMs, and remaining attention capacity for other tasks.
