1. A method of securing an aircraft against unauthorized direction or misdirection comprising:
- detecting a potential imminent unauthorized control input to the aircraft;
in response to the step of detecting, triggering a security mode whereby manual control of the aircraft navigation is disabled, and automatic control of aircraft navigation is commenced.

Abstract
A vehicle security system and method allows for the disabling of manual vehicle control, while automatic vehicle guidance provides control of the vehicle. The vehicle, which may be an aircraft, boat, train, truck, etc. is thus secured against unauthorized guidance that could harm passengers or other persons or property. In an embodiment, the security system automatically controls the vehicle to avoid collision with ground features when imminent collision is detected.

10. A method of securing an aircraft against misdirection resulting in a collision with a building or other ground structure or feature, comprising the steps of:
-
comparing a current location of the aircraft with the location of a particular ground feature in the vicinity of the aircraft'"'"'s current location by searching a database of ground feature locations;
determining, based on the step of comparing, that the current aircraft location and trajectory create a danger of imminent collision of the aircraft with the particular ground feature;
automatically disabling manual control of aircraft navigation based on the step of determining; and
calculating and causing to be automatically executed an evasive action of the aircraft whereby a collision with the particular ground feature is averted. - View Dependent Claims (11, 12, 13, 14, 15)

16. An apparatus for securing an aircraft against unauthorized direction or misdirection of the aircraft, the apparatus comprising:
-
a security navigation module further comprising;
an alarm interface to an alarm source for receiving an alarm signal directed to the security navigation module from the alarm source;
a control interface for sending communications to flight control facilities of the aircraft; and
a sensor interface for receiving communications from aircraft sensor facilities, whereby receipt of an alarm signal at the alarm interface is operative to cause the security navigation module to disable manual navigation control of the aircraft and to assert automatic control of the aircraft by sending a communication to the flight control facilities of the aircraft via the control interface, wherein the automatic control of the aircraft is based at least in part on signals received by the security navigation module at the sensor interface. - View Dependent Claims (17, 18, 19, 20, 21, 22)
