Which call notifies the flight to check their position based on last clearance?

The term that indicates a flight needs to check their position based on the last clearance is "AWOL." In aviation terminology, AWOL (Absent Without Leave) can refer to a situation where an aircraft may not be following the expected flight path or is unaccounted for in terms of communication and position reporting. This call alerts the crew of the necessity to reassess their current location and verify that they are on the correct course according to previous air traffic control instructions.

The other terms listed do not serve this purpose. For instance, "Abort" is typically used when a mission or operation is halted for safety or operational reasons, not specifically to check a flight's position. "ELEVATOR" generally refers to a flight control surface or may be a phrase used in other contexts unrelated to position checks. "Spin" refers to a situation where an aircraft enters a spin due to aerodynamic factors, which again does not relate to verifying position concerning clearances. Thus, AWOL is the correct choice, as it directly pertains to a flight needing to reassess their location following clearance instructions.
