From which directions can the glideslope be captured?

The glideslope provides vertical guidance to a runway and can be captured by the aircraft from either direction along the vertical plane. You don’t have to approach it only from above; if you’re above the glidepath, you’ll descend toward it, and if you happen to be below it, you can still capture it by climbing toward the path—both within the instrument’s capture envelope. Once the glideslope receiver locks onto the signal, the flight guidance will steer you along the 3-degree path to the runway. The key idea is that the ILS glideslope is designed to be intercepted from either direction, not just one specific side, hence it being capturable from above or below.
