That is my common sense answer. Someone will probably be along in a minute to say I'm wrong.
D.O.
There seem to be a couple of misconceptions people have on this subject. The following all relates to approaches in Glass G or D airspace within the UK.
- Regardless of IFR or VFR clearance, practice/simulated/'real' - you have no separation from VFR traffic - You MUST maintain a lookout. In class D the traffic should be called. In class G you have no separation from general IFR either - just participating IFR (ie. participating in your approach controller's service).
- I believe the logic for having an observer when 'practicing' vs. flying for real. Is that in VMC flying an ILS for real under IFR you will be flying predominantly looking outside for orrientation and positioning and looking at the needles to cross check. If you are 'practicing' you will be trying to fly the needles without looking out - and hence need someone else looking for traffic
- Being cleared for an ILS does not imply an IFR clearance (as demonstrated in the G-EYES accident)
- Obviously if you are in cloud looking out will be futile and hopefully there will be no 'VFR' or non-participating IFR traffic intersecting your approach track (and for example Lydd's DME arc that could be a 25 mile long path you are cutting through the sky on the approach).
A 'real' ILS in VMC IMHO provides very little training value as you need to be looking out the window for traffic and you get all the visual references as well.
