yes it’s also the LOC chart.
Thank you all for your inputs I’ll try to summarise:
You should be at or above the minimum altitude at the end of the Star which in this particular case is also the IAF.
On a hot day you’ll have a fly down on the GS and a fly up on the GS when it’s below ISA.
You should not rely on the GS for terrain clearance outside of 10 nm unless the chart states differently.
Many will follow the GS outside this distance.
IMHO you should cross other altitudes before 10 nm / FAP above the minimum charted altitudes.
Following the GS before the FAP on a hot day will have you below these altitudes indicated on the altimeter.
Assuming the GS is accurate outside 10 nm and you happen to be in the middle of the band width you will always be at the same vertical distance amsl if on the GS no matter what the temperature.
On a hot day you will have slightly increased terrain clearance if you adhere to the altitudes.
Following the GS on a hot day could mean infringing uncontrolled VFR airspace as the instance given a few posts ago.
Having to correct to the GS from above inside the FAP/ 10 nm will cause a potential increase in workload.
Your clearance will vary around the world.
“ clear ILS “
” once established on the LOC descend ILS”
” Cleared ILS XX cross xxx above xxxx”
Cheers all 👍
