wingtip777:
as we know KLAX is so busy that sometimes you can't get a chance to make a request on the radio. when approaching final on base, atc is too busy to give us an instruction, can we turn to final ? atherwise we will cross it
any documents or manuals mentioned about it?
thanks!
You don't specify whether you are speaking of an IAP or a visual approach.
The AIM is very specific about not turning inbound on an IAP without instructions and/or a clearance. (AIM 5-4-3)
Since the only other option at LAX would be a visual approach, if you are cleared for a charted visual, you follow the instructions on the chart unless ATC issues a restriction to the contrary.
AIM 5-4-23 covers visual approaches. If you are on a non-charted visual and haven't been given instructions to turn final, then ATC has violated their requirements. That would be worth a phone call after the fact.
