What did Charles Lindbergh use to be sure he was heading in the correct direction during his famous flight?

During his historic flight across the Atlantic in 1927, Charles Lindbergh relied on a combination of visual landmarks, a compass, and his flight instruments to maintain the correct heading. He used a map and navigational charts to track his position and course, along with the stars for celestial navigation at night. The use of these tools allowed him to adjust his direction as needed, ensuring he stayed on track to reach Paris.
