I've been at GCLP (Las Palmas de Gran Canaria, Spain) a few weeks ago.
I've observed that all incoming traffic was guided by a Follow Me while outgoing traffic went without one.
I was curious about that and looked for an airport chart to find more about it. The latest I've found is a Jeppesen chart from DEC 2004... so a bit outdated.
There it states in the LVP (Low Visibility Procedures) section only, that pilots have to wait at apron entry for the Follow Me while outgoing traffic should avoid requesting clearance in such a situation.
There is no notice, about what applies when LVP is not active.
What could be the reason for doing this even in good weather situations (visibility was at least 10km, if not even more)?
