Give an example of an API 1 duty.

• A. A ground controller coordinating runway ops
• B. A pilot performing flight duty each day
• C. A loadmaster in cargo hold
• D. A flight nurse on medical team

Answer: (B)

API 1 duty means a role where the day-to-day responsibilities are centered on flying as part of regular duty. The pilot performing flight duty each day is the clearest example because their main task is to operate aircraft and carry out missions or training in the air as part of their normal schedule. The other roles, while essential, are not primarily defined by daily in-flight duty: a ground controller works on runway operations from the ground; a loadmaster handles cargo operations rather than the core flying task; a flight nurse serves on a medical team and may fly, but their primary focus is medical support rather than standard daily aircrew flight duties.
