Methods and systems are provided for providing information relating to taxiing an aircraft at an airport having a plurality of taxi paths. One exemplary method involves identifying a first aircraft location on a first taxi path and a first aircraft heading along the first taxi path, and determining a first subset of possible taxi paths from the plurality of taxi paths based on the first aircraft location and the first aircraft heading, such that each respective taxi path of the first subset intersects the first taxi path at a respective intersection location in the first aircraft heading from the first aircraft location. The method continues by receiving a first input, and when the first input corresponds to a second taxi path of the first subset, providing indication of the second taxi path.
