copilot says no, I say yes.
You are given PD to a lower altitude.
You continue at cruise altitude 10 mins then start down.
A 'vacating' call is required by the regs.

Do I owe him a beer?
top marks only to referenced responses.
 
I once flew with a guy who announced after every drink: "leaving beer 3 for beer 4" etc... After that, I thought anyone who reported vacating an altitude was a ******************************bag. But I think it is a reg nonetheless.
 
OK, so if it's is required by FAR, which FAR? (Serious question, I'm not being an azz.) I thought the only place this is discussed is in AIM 5-3-3(a)(1)(a).
 
While not specific , FAR 91.183(c) says that:

Unless otherwise authorized by ATC, the pilot in command of each aircraft operated under IFR in controlled airspace must ensure that a continuous watch is maintained on the appropriate frequency and must report the following as soon as possible—
(a) The time and altitude of passing each designated reporting point, or the reporting points specified by ATC, except that while the aircraft is under radar control, only the passing of those reporting points specifically requested by ATC need be reported;
(b) Any unforecast weather conditions encountered; and
(c) Any other information relating to the safety of flight

one could infer that vacating an assigned altitude, while descending to another assigned altitude, in a timeframe as determined by the pilot and not the controlling authority(ies) would constitute a safety of flight issue and be covered by (c) above....

I could be wrong, but I disagree. The controller is saying: you are at X altitude, and when you're ready descend to Y altitude. ATC is giving you both altitudes and everything in between. Although I do report vacating altitudes, I don't think its required.
 
IMHO and that of my crusty old "On-wing" instructor in the Navy, it's not required by FAR or the AIM since you've already acknowledged the instruction when responding to the original clearance of PD FLXXX.
That said, I usually let'em know just for the hell of it unless the freq. is slammed.
 
This is all I found.4-4-10. Adherence to Clearance
c. The term "AT PILOT'S DISCRETION" included in the altitude information of an ATC clearance means that ATC has offered the pilot the option to start climb or descent when the pilot wishes, is authorized to conduct the climb or descent at any rate, and to temporarily level off at any intermediate altitude as desired. However, once the aircraft has vacated an altitude, it may not return to that altitude.
I don't think it is "required" but we do it as a curtsey.
 
5-3-3. Additional Reports
a. The following reports should be made to ATC or FSS facilities without a specific ATC request:
1. At all times.
(a) When vacating any previously assigned altitude or flight level for a newly assigned altitude or flight level.
 
Rice is one smart MOFO, and an EASy expert...and hell even if he reeks like Curry, I agree with him.

You have made the required report when you acknowledged the Descent clearance, even if you wait another 5 mins for VNAV .

Its a courtesy call.

Hence usually a quick "roger" when you make it. They wont re-issue the clearance or confirm anything. They really dont care IMO.

Has anyone ever not made the courtesy call right away and gotten questioned or violated for leaving altitude? I never have....sometimes it takes 500-1000ft to get room on the frequency and all you ever get is "roger"...

Just my .02

In this case a 'vacating' call would be redundant and for that matter, not required.

When a controler gives you a PD clearance and you accept it, at that time you've accepted the entire clearance limit for that block altitude. Also, by accepting the PD clearance you have vacated the previosly assigned altitude. You are no longer flying at that assigned altitude and are now opperating in the block altitude.

So with that being said, in your block altitude that you've been given you could temprarily level off 10 times if you wanted to, but in the same sense you're not required to give a 'vacating' call after every time you do.


I think you owe him a beer.

hmmm the usual legal quandary that pilots face...
its not in the FARS, but IS in the AIM.
"AIM is not regulatory".....BUT some say the FAA has busted people for what IS in the AIM.....a de facto statement that the AIM IS INDEED REGULATORY!!!
