Similar to the ‘Please wait for clearance before crossing the runway’ and the ‘Please wait for clearance before taxiing’ command on ground; this command would help ATC inform pilots that they need a clearance before descending altitude on FIR. It would sound like ‘Please wait for clearance before descending’ and would look like the image below:
If implimented, this will teach pilots that they need to descend with a clearance to a direct altitude or through a STAR. Without this, you can’t judge when they will descend and could result in a loss of separation.
Got my Vote for sure! This Feature would really help Radar Controllers since we have this Feature already for Tower ,Please wait for clearance before taxiing” or ,Please wait for clearance before crossing the runway” I think it’s a cool idea to get this feature for radar too. 👏🏻
If nobody is online, you can begin your descent without request. If Center comes online, just request a descent via the STAR (or an altitude change if you don’t have a STAR in your FPL), and then keep descending as normal after you’ve been approved (or follow ATC instructions if given).
