Flight restriction zone detection and avoidance
First Claim
1. A method to indicate an actual or potential Temporary Flight Restriction (TFR) zone violation and indicate measures to avoid or exit a TFR zone, comprising:
- receiving TFR zone information and an aircraft'"'"'s position information, ground track and ground speed;
processing the aircraft'"'"'s position information, ground track and ground speed to determine the aircraft'"'"'s current heading;
determining whether there is a TFR zone violation based on the aircraft'"'"'s current position, whether the aircraft'"'"'s current heading results in a potential TFR violation based on the aircraft'"'"'s current position and heading and whether the aircraft is in the vicinity of a TFR zone based on the aircraft'"'"'s current position and heading;
providing indicators of a TFR zone violation, potential TFR zone violation when the aircraft is at a predetermined distance from the TFR zone or if the aircraft will intersect the TFR zone in a predetermined amount of time, no TFR zone violation or absence of a TFR zone in the vicinity; and
if a TFR zone violation, or possible TFR zone violation or presence of a TFR zone in the vicinity are determined, providing indicators of measures to exit the TFR zone or change the aircraft'"'"'s current heading to avoid the TFR zone.

Abstract
A method, system and computer program product to detect and indicating TFR zone violations, potential TFR zone violations or TFR zones in vicinity of an aircraft and indicating measures to avoid or exit a TFR zone are provided. TFR zone information and an aircraft'"'"'s position information are received. The aircraft'"'"'s position information is processed to determine the aircraft'"'"'s current heading. A TFR zone violation is determined based on the aircraft'"'"'s current position. A potential TFR violation is determined based on whether the aircraft'"'"'s current heading intersects a TFR zone. The presence of a TFR zone in the vicinity of the aircraft is determined based on the aircraft'"'"'s current position and heading. Indicators of a TFR violation, potential TFR violation, no TFR violation or TFR zones in the vicinity are provided. If a TFR violation, or possible TFR violation or TFR zone in the vicinity are found, measures are indicated to exit the TFR zone or change the aircraft'"'"'s current heading to avoid the TFR zone.

8. A system to detect and indicate a TFR zone violation, potential TFR zone violation or a TFR zone in vicinity of an aircraft and indicate measures to avoid or exit a TFR zone comprising:
-
a user interface configured to provide indicators; and a computing device; wherein the computing device is configured to receive downloaded or stored TFR zone information, aircraft position information, ground track and ground speed, and determine the aircraft'"'"'s current heading based on the aircraft'"'"'s position information, ground track and ground speed, determine whether the aircraft violates a TFR zone based on the received aircraft position information and TFR zone information, determine a potential TFR zone violation based on the aircraft'"'"'s current heading and TFR zone information, indicate actual TFR zone violation or potential TFR zone violation when the aircraft is at a predetermined distance from the TFR zone or if the aircraft will intersect with the TFR zone in a predetermined amount of time, indicate a TFR zone in an aircraft'"'"'s vicinity and indicate measures to exit a TFR zone or avoid a TFR zone violation. - View Dependent Claims (9, 10, 11, 12)

13. A method to indicate a current or potential Temporary Flight Restriction (TFR) zone violation and indicate measures to avoid or exit a TFR zone, comprising:
-
receiving TFR zone information; receiving aircraft position, ground track and ground speed information; processing aircraft position, ground track and ground speed information to determine the aircraft'"'"'s current heading; determining whether the aircraft'"'"'s current heading is intersecting a TFR zone; determining whether a TFR zone is in the vicinity of the aircraft; determining whether the aircraft is in a TFR zone; providing indication of presence one or more TFR zones in the vicinity of the aircraft or presence of the aircraft inside a TFR zone or possible intersection of the aircraft with a TFR zone when the aircraft is at a predetermined distance from the TFR zone or if the aircraft will intersect the TFR zone in a predetermined amount of time; indicating measures to exit a TFR zone if the aircraft is currently in a TFR zone; indicating measures to avoid a TFR zone if the aircraft'"'"'s current heading intersects a TFR zone; and indicating presence and location of a TFR zone if the TFR zone is in the vicinity of the aircraft. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
