-	// fplPatternString is a regular expression designed to parse and extract detailed information from formatted flight plan strings.
-	// The flight plan string is expected to follow a specific format, encapsulated by parentheses and containing various segments separated by hyphens.
-	// Each segment captures a different aspect of the flight plan, as detailed below:
-	//
-	// - category: Matches a three-letter flight category code.
-	// - number: Matches the flight number, consisting of letters followed by digits.
-	// - indicator: Matches a two-letter indicator.
-	// - aircraft: Matches the aircraft registration or type, which may include a slash and an optional letter.
-	// - surve: Matches surveillance equipment information, capturing any characters in this segment.
-	// - departure: Matches the four-letter code of the departure airport.
-	// - departure_time: Matches the four-digit departure time.
-	// - speed: Matches the speed, consisting of letters followed by digits.
-	// - level: Matches the flight level, which can include letters and digits.
-	// - route: Matches the flight route, capturing any characters in this segment.
-	// - destination: Matches the four-letter code of the destination airport.
-	// - estt: Matches the four-digit estimated time of arrival.
-	// - alter: Matches the four-letter code of an alternate airport.
-	// - pbn: Matches performance-based navigation equipment information.
-	// - nav: Matches navigation equipment information.
-	// - reg: Matches the aircraft registration.
-	// - eet: Matches the estimated elapsed time, including the four-letter code and four-digit time.
-	// - sel: Matches the SELCAL code.
-	// - performance: Matches a single letter indicating the aircraft's performance category.
-	// - rif: Matches reroute information, including any characters in this segment.
-	// - remark: Matches remarks, capturing any characters in this segment.
-	//
-	// The regular expression uses named capture groups for each segment, allowing for easy extraction of specific information from a matched flight plan string.

+	// - departure: the four-letter departure airport code
+	// - departure_time: the four-digit departure time
+	// - speed: one or more uppercase letters followed by one or more digits (e.g., N123)
+	// - level: one or more alphanumeric characters (e.g., FL350)
+	// - route: one or more characters (including newline) representing the flight route
+	// - destination: the four-letter destination airport code
+	// - estt: the four-digit estimated time of arrival
+	// - alter: one or more sequences of a whitespace character followed by exactly four uppercase letters
+	// - other: any other relevant information, starting with three uppercase letters followed by a forward slash and zero or more characters (including newline)
