Question

Aircrew members will not fly within ____ after donating blood, plasma, or bone marrow

Option 1: 24 hours
Option 2: 48 hours
Option 3: 72 hours
Option 4: 96 hours

Answer 1

Aircrew members will not fly within 24 hours after donating blood, plasma, or bone marrow.

Step-by-step explanation:

Aircrew members will not fly within 24 hours after donating blood, plasma, or bone marrow. This is to ensure that the body has enough time to recover and replenish the donated substances. Aircrew members should not fly within 72 hours after donating blood, plasma, or bone marrow. The downtime is necessary because donating can affect a person's physical condition, such as reducing blood volume and potentially causing anemia or fatigue, which may impair their ability to perform duties safely while flying. Unlike the immediacy of organ transplant timelines, such as the four-hour window for a heart to be viable post-donation, the safety guideline for returning to fly post-donation is set to ensure the aircrew members' well-being is restored before operating an aircraft.
