The system includes a display for a leader aircraft configured to display a current position of one or more aircraft of the plurality of aircraft. The system further includes a controller for the leader aircraft configured to at least one of receive a current position signal from one or more aircraft of the plurality of aircraft, calculate the current position of the one or more aircraft of the plurality of aircraft, or calculate a target position of the one or more aircraft of the plurality of aircraft. The system further includes a transmitter configured to transmit the target position signal to the one or more aircraft of the plurality of aircraft. ## Claims ### Claim 1 A formation monitoring system a plurality of aircraft flying in formation comprising: a lead display for a leader aircraft configured to: display a current position of one or more aircraft of the plurality of aircraft wherein the leader aircraft is piloted by a lead pilot; differentially display the current position of the one or more one aircraft of the plurality of aircraft from a target position of the one or more aircraft of the plurality of aircraft; and indicate when the one or more aircraft of the plurality of aircraft have moved to the target position; a lead controller communicatively coupled to the lead display, configured to: receive a position signal from one or more follower aircraft of the plurality of aircraft; calculate the relative position of the one or more follower aircraft of the plurality of aircraft; wherein the relative positions of the one or more follower aircraft of the plurality of aircraft are displayed on the lead display; and determine a target position for one of the one or more follower aircraft; a lead user interface communicatively coupled to the lead controller, wherein the lead pilot can input at least one of a target position signal or a reassignment signal; a lead transmitter communicatively coupled to the lead controller configured to transmit the target position signal and a reassignment signal to the one or more follower aircraft of the plurality of aircraft; a follow display for the one or more follower aircraft, wherein the follower aircraft is piloted by a follow pilot; and a follow controller communicatively coupled to the follow display configured to: receive the target position signal; and receive the reassignment signal, wherein upon receiving the reassignment signal, the follower controller is reassigned as a lead controller; a follow user interface communicatively coupled to the follow controller, where upon the follow controller receiving the reassignment signal, is configured to receive a second target position signal input from the follow pilot; and a follow transmitter communicatively coupled to the follow controller configured to transmit a second target position signal to another aircraft of the plurality of aircraft. ### Claim 2 (depends on 1) The system of claim 1, further comprising: an aircraft selector configured to select one of the one or more follower aircraft of the plurality of aircraft displayed on the display; a target position selector configured to select a target position on the display for the one or more follower aircraft selected by the aircraft selector. ### Claim 3 (depends on 1) The system of claim 1, wherein the lead display is further configured to differentially display at least one of the leader aircraft or an ownship from the plurality of aircraft. ### Claim 4 (depends on 1) The system of claim 1, wherein the lead display is further configured to indicate when all aircraft of the plurality of aircraft are in the target position. ### Claim 5 (depends on 1) The system of claim 1, wherein the lead display is further configured to indicate a path from the current position of or more or the plurality of aircraft to the target position of the one or more of the plurality of aircraft. ### Claim 6 (depends on 1) The system of claim 1, wherein the lead display is further configured to display an approximation of the flight formation. ### Claim 7 (depends on 1) The system of claim 1, wherein the lead display is configured as a portion of a primary flight display. ### Claim 8 A formation monitoring system for a plurality of aircraft flying in formation comprising: a lead display for a leader aircraft of the plurality of aircraft configured to: display a current position of one or more aircraft of the plurality of aircraft; differentially display the current position of the one or more one aircraft of the plurality of aircraft from a target position of the one or more aircraft of the plurality of aircraft; and indicate when the one or more aircraft of the plurality of aircraft have moved to the target position, wherein the leader aircraft is piloted; an aircraft selector for the leader aircraft of the plurality of aircraft configured to select the one or more aircraft of the plurality of aircraft displayed on the lead display; a target position selector for the leader aircraft of the plurality of aircraft configured to select a target position on the lead display for the one or more aircraft of the plurality of aircraft selected by the aircraft selector; a lead controller for the leader aircraft of the plurality of aircraft, configured to: receive a current position signal from the one or more aircraft of the plurality of aircraft; calculate the current position of the one or more aircraft of the plurality of aircraft; wherein the current position of the one or more aircraft of the plurality of aircraft are displayed on the lead display; and calculate the target position of the one or more aircraft of the plurality of aircraft, wherein the relative positions of the target positions of the one or more aircraft of the plurality of aircraft are displayed on the lead display; and a transmitter configured to transmit the target position signal to one or more follower aircraft of the plurality of aircraft; a follow display for the one or more follower aircraft, wherein the follower aircraft is piloted by a follower pilot; and a follow controller for the one or more follower aircraft of the plurality of aircraft configured to: receive the target position signal from the leader aircraft; receive a reassignment signal from the leader aircraft; and calculate the target position of the one or more follower aircraft, wherein the relative positions of the target positions of the one or more aircraft of the plurality of aircraft are displayed on the follower display, wherein upon receiving a reassignment signal, the follower controller is reassigned as a lead controller; and a follow user interface communicatively coupled to the follow controller, where upon the follow controller receiving the reassignment signal, is configured to receive a second target position signal input from the follow pilot; and a follow transmitter communicatively coupled to the follow controller configured to transmit a second target position signal to another aircraft of the plurality of aircraft. ### Claim 9 (depends on 8) The system of claim 8, wherein the follower display is further configured to differentially display at least one of the leader aircraft or an ownship from the plurality of aircraft. ### Claim 10 (depends on 8) The system of claim 8, wherein the lead display is configured as a portion of a primary flight display.
