Just a query. When handed over to Tower and contacting them…….is there any requirement to let them know you are established on the ILS? Or is it sufficient to just say your call sign? Reason being that Approach would have already told the Tower that you have been cleared the ILS and they are going to hand you over to them. Hence reducing air time.
It's more important that they know and you know the runway and type of approach you're doing. Approach are humans too and could always accidentally give Tower the wrong approach. Everyone being on the same page is more important than 1-2 seconds of reduced radio time. Even if it is redundancy, aviation is made up of those.
If we are cleared for the ILS Approach Runway XX. I am on LNAV, going towards Initial Approach Fix at 1600 feet. My next altitude was 1500 feet. Can I wind down my altitude and follow the approach chart altitudes as published? Please advise. Some say we can’t while some say we can wind down to the published altitude since we are already cleared for the approach and on the LNAV route.
