Not sure I understood what you were saying here but ATC instructions are very clear, they will only clear you for one approach.

You can be cleared for an "ILS" OR for a "LOC" if your approach plate say LOC. If such plate does not exist you'll be cleared for an "ILS glideslope OUT."


Folks, it boils down to safety but also to plain ole' common sense.

Do NOT put any extra distractions on yourselves, we have enough of those as it is and IF something were to happen, trust me, the FAA won't come to defend you to say, "well, technically I guess you can do it..."

Going missed is very simple, re-brief for a new approach, change the minimums alt. buggs, brief the new missed procedure, etc, and do it again.

You'll never get in trouble for saying, "I thought it'd be safer to go-around and give it another try..."

Just my 2¢
