What happens if both pitot and static ports become blocked?

Explanation:
When both pitot and static ports are blocked, the main source of pressure data for airspeed, altitude, and vertical speed is lost, so the primary air data instruments may fail or freeze at a last known value. In this situation, pilots can still fly using standby instruments, which are powered by a separate source and provide attitude, a reliable altimeter, and a backup airspeed reference. This setup lets the aircraft remain controllable and reachable for landing, even though the primary air data readings are unreliable.
