Final answer:
A consideration when taxing out to a runway at a non-towered airport with low visibility or a low ceiling is the importance of maintaining situational awareness and following instructions.
Step-by-step explanation:
When taxing out to a runway at a non-towered airport with visibility less than 2 miles or a ceiling less than 800 feet, a consideration to take into account is the reduced visual range. Pilots should ensure they have proper navigational aids and instruments to assist them in maintaining situational awareness during taxiing and takeoff. Additionally, it is important to adhere to any specific procedures or instructions issued by air traffic control or published in the airport's chart supplement.
