Intercepting the ILS
PPRUNE is complaining I have not contributed for a while so here goes...
When I was taught (PPL IMC), the ILS intercept was always localiser first then glideslope. And the glideslope was always approached from beneath (typically straight and level). Trying to get onto the glideslope from above was a strict no no.
However, I am curious as to what is common practice with a modern airliner. In particular, we hear a lot about continuous descent. Is it actually possible to intercept the glideslope from a completely power idle descent (ATC permitting)?
