Quick question about Nav setting (i read tutorials already)

When I try to set EGLL R27L as nav1 (while im preparing at madrid), it says ILS out of range…
no kidding? i thought nav1 was just a preset for the airplane to automatically catch on to the ILS when approaching the airport…is this not how it works?

You need to get within 27 miles of the runway before you can tune to the ILS. You need to select the runway/ILS and set it to NAV1 and then you can capture it with APPR using Trio’s instructions.

oof. sry for unnecessary question. I remember that now
