How far from the runway centerline is the glideslope antenna typically located?

The glideslope antenna is typically located between 250 to 600 feet from the runway centerline. This positioning is crucial for ensuring that the glideslope signal is accurate and provides pilots with the correct descent angle towards the runway during an Instrument Landing System (ILS) approach.

When the glideslope antenna is situated within this range, it allows for optimal reception of the glideslope signal by the aircraft's equipment, contributing to a stabilized approach in various weather conditions. The design of the ILS, including the glideslope's location, is based on extensive aeronautical engineering principles to enhance safety and efficiency in aviation operations.

Understanding the location of the glideslope antenna is essential for flight instructors and students, as it underlines the importance of accurate navigation aids during instrument flight. The other options do not align with the standard specifications used in aviation regarding the placement of the glideslope antenna.
