A pilot interface panel may comprise at least one input mechanism configured to receive at least one user input, generate at least one input signal corresponding to the at least one user input, and send the at least one input signal to a controller. The controller may be configured to control movement of an electric taxi system of an aircraft in a manner according to the at least one input signal, wherein the electric taxi system may be configured to rotate at least one wheel of the aircraft by force from a purely electromotive source. The pilot interface panel may further comprise at least one safety mechanism, which may be configured to prevent at least one of the at least one input mechanisms from receiving an inadvertent user input resulting from an unintended action by the user.

1. A pilot interface panel, comprising: an input mechanism configured to: receive a user input through a control lever that can move along a longitudinal path,generate an input speed signal corresponding to the one user input, andsend the input speed signal to a controller, the controller configured to control movement of an electric taxi system of an aircraft in a manner according to the input speed signal, and the electric taxi system configured to rotate a wheel of the aircraft by force from a purely electromotive source; anda safety mechanism configured to prevent the input mechanism from receiving an inadvertent user input resulting from an unintended action by the user, wherein the safety mechanism includes: a lever lock, on the control lever, which upon movement in a direction generally perpendicular to the longitudinal path, enables the control lever to move along the longitudinal path;a resume switch, on the control lever, which until activation, prevents the controller from responding to a new input speed signal. 2. The pilot interface panel of claim 1, wherein the input mechanism includes an engagement mechanism configured to receive an engagement input and generate a corresponding engagement input signal indicating a request to activate a clutch engagement sequence for the electric taxi system. 3. The pilot interface panel of claim 1, wherein the input mechanism includes a speed input mechanism configured to receive a speed input for a target taxi speed and generate a corresponding speed input signal indicating a request to reach the target taxi speed. 4. The pilot interface panel of claim 3, wherein the speed input mechanism includes a detent configured to provide resistance to movement of the control lever. 5. The pilot interface panel of claim 3, wherein the resume switch is configured to receive a resume input and generate a corresponding resume input signal indicating a request to resume the target taxi speed. 6. The pilot interface panel of claim 1, wherein the input mechanism includes a reverse input mechanism configured to receive a reverse input and generate a corresponding reverse input signal indicating a request to move the aircraft in a reverse motion. 7. The pilot interface panel of claim 6, the safety mechanism includes a reverse lockout member configured to prevent the reverse input mechanism from receiving an inadvertent user input resulting from an unintended action by the user, the reverse lockout member being maneuverable to allow the reverse input mechanism to receive a reverse input. 8. The pilot interface panel of claim 1, wherein the input mechanism includes a pivot input mechanism configured to receive a pivot input and generate a corresponding pivot input signal indicating a direction for pivoting the aircraft. 9. The pilot interface panel of claim 8, wherein the pivot input mechanism defaults to a neutral position and generates a signal indicating no pivot of the aircraft desired. 10. The pilot interface panel of claim 8, the safety mechanism includes a switch guard configured to prevent the pivot input mechanism from receiving an inadvertent user input resulting from an unintended action by the user. 11. The pilot interface panel of claim 1, further comprising a plurality of response mechanisms configured to communicate system states to the user. 12. An aircraft taxi interface system, comprising: a pilot interface panel configured to: receive user input via a pivot switch,generate an input wheel pivot signal corresponding to the user input, andprovide a safety mechanism configured to prevent the input mechanism from receiving an inadvertent user input resulting from an unintended action by the user, wherein the safety mechanism includes:a safety guard hinged at one end and rotatable at the hinged end to expose the pivot switch;wherein the pivot switch is configured to: default to a neutral position that prevents a pivot turn of a wheel of the aircraft;send, when the pivot switch is out of the neutral position, a signal to a controller to start a turn process if certain conditions are satisfied;wherein the conditions include at least one of the wheel being in a caster mode and a speed of the aircraft is zero; andthe controller being in communication with the pilot interface panel and a motor control unit, the motor control unit configured to control a motor of an electric taxi system of an aircraft, the electric taxi system configured to rotate a wheel of the aircraft by force from a purely electromotive source, the controller being operable to: receive the input wheel pivot signal from the pilot interface panel,determine an action for the electric taxi system based on the input wheel pivot signal,generate a command corresponding to the action, andsend the command to the motor control unit, wherein the motor control unit initiates the action in the electric taxi system. 13. The aircraft taxi interface system of claim 12, wherein the user input includes a target velocity, and the action includes one of accelerating or decelerating the aircraft to reach the target velocity. 14. The aircraft taxi interface system of claim 12, wherein the user input includes a target velocity and a resume input, and the action includes one of accelerating or decelerating the aircraft to reach the target velocity of movement when the resume input is positive. 15. The aircraft taxi interface system of claim 12, wherein the controller is further operable to receive a set of status inputs, the user input includes a first pivot input indicating a first direction, and the action includes rotating the aircraft via the electric taxi system. 16. The aircraft taxi interface system of claim 15, wherein the user input further includes a second pivot input indicating a second direction opposite the first direction, and the action includes interrupting a motion of a first motor of the electric taxi system and allowing a continued motion of a second motor of the electric taxi system. 17. The aircraft taxi interface system of claim 12, wherein the controller is further operable to receive a left brake input and a right brake input, the user input includes a speed input, and the action includes canceling the speed input if the left brake input is positive, the right brake input is positive, or both left and right brake inputs are positive. 18. The aircraft taxi interface system of claim 12, wherein the controller is further operable to receive a left brake input and a right brake input, the user input includes a speed input, and the action includes canceling the speed input only if both left and right brake inputs are positive. 19.
