Currently, in many countries the use of face masks is recommended or compulsory especially if social distancing is not possible. In the recommendations of ICAO, CAPSCA, and IATA, the use of face masks in the cockpit while operating the aircraft has not been compulsory. When an operator makes a decision on mask use in the cockpit, it should involve a safety risk assessment. IFALPA's position is that flight crew should have the option to remove their mask in the cockpit when the door is closed in the interest of flight safety. This safety bulletin provides some factors that should be taken into consideration.
