In today's world, Single frequency approach is a topic that has captured the attention of people of all ages and interests. With the growing interest in this topic, it is important to understand its implications and consider its impact on different areas of society. Whether from a historical, scientific, cultural or social perspective, Single frequency approach has been the subject of numerous debates and discussions, generating an increasing interest in knowing more about its origins, its evolution and its relevance today. In this article, we will explore different aspects related to Single frequency approach, analyzing its importance and addressing various points of view to offer a complete overview of this fascinating topic.
In aviation, a single frequency approach (SFA) is a service for a military single-piloted turbojet aircraft to use a single UHF frequency during their landing approach. Circumstances permitting, pilots will not be required to change their frequency when they switch from ARTCC to terminal facility control when conducting an SFA.
In the U.S., per the FAA, controllers are not allowed to require a frequency change from aircraft conducting an SFA unless:
- Pilot has completed landing or low approach
- Aircraft is in VFR conditions during daylight hours
- Pilot requests a frequency change
- Emergency situation exists
- Aircraft is cleared for a visual approach
- Pilot cancels their IFR flight plan
If a change of control is necessary, controllers will hand off the frequency to each other, instead of having the pilots change the frequency on their radio.
