Final answer:
VFR aircraft usually squawk 1200 or a unique ATC-assigned code for flight following in the NAS of the United States.
Step-by-step explanation:
VFR aircraft normally squawk either 1200 or an ATC-assigned flight following code.
In the context of aviation operations, when flying under Visual Flight Rules (VFR), pilots use specific transponder codes to identify their aircraft on radar. In the continental United States, aircraft that are not under Air Traffic Control (ATC) flight following typically use the squawk code 1200. However, if a pilot requests ATC services such as flight following, a unique transponder code, different from 1200, will be assigned to that aircraft to help ATC track it more precisely. It's important to note that these codes can vary by region and the procedures outlined are specific to the National Airspace System (NAS) of the United States.
In aviation, VFR stands for Visual Flight Rules, and it is a set of regulations that govern the procedures for conducting flights in visual meteorological conditions.When flying under VFR, aircraft usually squawk either 1200 (which is the standard VFR squawk code) or an ATC-assigned flight following code.A squawk code is a four-digit transponder code that identifies an aircraft on radar to air traffic control (ATC). By squawking a code, ATC can monitor the aircraft's position and provide guidance and instructions if needed.
