A sensing orifice for an aircraft, an aircraft with such a sensing orifice and a method for assembling a sensing orifice for an aircraft are provided. The aircraft may be an airplane, a helicopter, a UAV, a drone or similar. The static sensing orifice includes a passage through an outer skin of the aircraft and a moisture protection body. The passage is designed to connect with a pressure line in the interior of the aircraft. The moisture protection body is gas-permeable and water-impermeable, and the moisture protection body is disposed such that the passage is gas-permeably and water-impermeably sealed. The method for assembling the static sensing orifice for the aircraft, includes the following steps: providing the passage through the outer skin of the aircraft for connecting to the pressure line in the interior of the aircraft, providing a gas-permeable and water-impermeable moisture protection body, and gas-permeable and water-impermeable sealing of the passage by the moisture protection body.
