+## <a id="msp2_inav_set_wp_index"></a>`MSP2_INAV_SET_WP_INDEX (8737 / 0x2221)`
+**Description:** Jumps to a specific waypoint during an active waypoint mission, causing the aircraft to immediately begin navigating toward the new target waypoint.
+
+**Request Payload:**
+|Field|C Type|Size (Bytes)|Units|Description|
+|---|---|---|---|---|
+| `wp_index` | `uint8_t` | 1 | - | 0-based waypoint index to jump to, relative to the mission start waypoint (`posControl.startWpIndex`) |
+
+**Reply Payload:** **None**
+
+**Notes:** Returns error if the aircraft is not armed, `NAV_WP_MODE` is not active, or the index is outside the valid mission range (`startWpIndex` to `startWpIndex + waypointCount - 1`). On success, sets `posControl.activeWaypointIndex` to the requested index and fires `NAV_FSM_EVENT_SWITCH_TO_WAYPOINT_JUMP`, transitioning the navigation FSM back to `NAV_STATE_WAYPOINT_PRE_ACTION` so the flight controller re-initialises navigation for the new target.
+
+---
+
+## <a id="msp2_inav_set_cruise_heading"></a>`MSP2_INAV_SET_CRUISE_HEADING (8739 / 0x2223)`
+**Description:** Sets the course heading target while Cruise or Course Hold mode is active, causing the aircraft to turn to and maintain the new heading.
+
+**Request Payload:**
+|Field|C Type|Size (Bytes)|Units|Description|
+|---|---|---|---|---|
+| `heading_centidegrees` | `int32_t` | 4 | centidegrees | Target heading in centidegrees (0–35999). Values are wrapped modulo 36000 before being applied. |
+
+**Reply Payload:** **None**
+
+**Notes:** Returns error if the aircraft is not armed or `NAV_COURSE_HOLD_MODE` is not active. On success, sets both `posControl.cruise.course` and `posControl.cruise.previousCourse` to the normalised value, preventing spurious heading adjustments from `getCruiseHeadingAdjustment()` on the next control cycle.

+
 ## <a id="msp2_betaflight_bind"></a>`MSP2_BETAFLIGHT_BIND (12288 / 0x3000)`
 **Description:** Initiates the receiver binding procedure for supported serial protocols (CRSF, SRXL2).
