Decent from FL350

So, I need some clarification on proper procedures here. We are level at FL350, about to start our descent profile arrival plans into MDW.

Center calls over, and says Citation NXXX descend pilots discretion, maintain one one thousand. (11,000). So i comply over the radio. The CA wants to stay at 350 for awhile longer (no problem there).

About 5 minutes later, he says, Call up Chicago and tell them we are leaving FL350 for 11k. So, I complied even though I thought this was incorrect to "RE- respond with our clnc altitude."

ATC has already told us to descend whenever we want (pilots discretion) down to our next cleared to altitude which is 11k feet. Keep in mind, as we learned back in Instrument learning/teaching days. One of the required radio calls is "ALTITUDE WHEN LEAVING ASSIGNED"- This makes perfect sense if we are leaving our assigned altitude WITHOUT being given permission., that is my understanding of it.

So, just to clarify, I'm under the "assumption" that you do not have to "re-report leaving your assigned altittude" when you ahve already been cleared down to a previous altitude through a pilots discretion descent. IF there is traffic in the way, or something, they will usually stop your descent or have you expedite a good rate through a few flight levels to get away from it or vice versa.


So before I talked to the CA about clogging up the radios with non essential radio talk, i figured I would hash it out and drop the dead donkey a few times here first. (Background on the CA, he is a younger guy, maybe low 40's, never was a CFI (not that it matters), flew regionals for awhile, then corporate and now charter 135 stuff, So its not a lack of experience on his part, if anything its a lack on mine since I just started flying the Jet part time in October and now Full time in February.

Thoughts? And I really hope this was not an "your an idiot BC questions, everyone knows this"! :laff: I admit I slept through a few days back in training like everyone else haha.

Thanks

(Further clarification- This is not a thread on CA bashing or ignoring the CA or proving who is right or who is wrong, its just a question on proper protocol that you have heard or NOT heard on the radio, CA is big on radio calls and proper etiquette, and I have not heard many other aircraft re-calling their descent into center/approach, etc, so that's why im asking"

(And yes- I finally figured out how to do the POLL thing- Thanks DOUG! haha)- ALSO I NOTICE NOW- I really am an IDIOT and I spelled WAY WAY WAY too many things wrong for being a college educated idiot!
 
Out of all the captains I have flown with, I can count the number of times on one hand that they have reported "leaving XXX altitude" when given a PD or crossing restriction.

Maybe we have all been f-ing it up? I just assume that it is like descending via (ELDEE3) arrival with crossing restrictions from FL270 to 8000 on our own without having to report where we are all the time.

Also, it seems like we get a PD descent when there is absolutely no one else around for 100's of miles to run into.
 
On a discretionary descent you should call and let ATC know when you start down. Check the AIM, I think it's in there but right now I don't have time to dig. Sorry. :(
 
I could also be wrong, but I've always reported the altitude I'm leaving if I'm leaving it some time after i was given the instruction.

I remember looking for this very thing a few months ago and couldn't find anything.

:yeahthat:


I think it's more of a courtesy thing, but I've never been yelled at by ATC for letting them know that I'm starting down.
 
Adherence to Clearance AIM 4-4-10 (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.

x2.

I do it 99% of the time. The thorough captains I fly with do it as well. I've never been yelled at for not doing it, but have always been taught that it's the right thing to do.

I find they often thank us for it as well. Once we start down, we generally add the courtesy call Skw6### leaving FL250 decending 1...1...thousand. I think the controller was just making sure you passed along your clearence, clarence:)
 
I fly with a few people that like to call, and some that do not. Personally, I feel the way you do... they have given you the clearance and could care less when you descend probably because no one is going to be in your way.

right, but the call does give them an opportunity to double check their work, and notice any unexpected traffic for your descent.
 
i say when we are leaving altitudes. Granted we level off usually around 15,000 feet so we dont get much when it comes to pd.
 
I actually was told by a CA to stop making that call on our 4 day. I always tried to do it. A lot of times when I would call they'd give me a new freq, so I felt like I was doing something worthwhile.

I am curious as to the answer however as it kinda peeved me when he told me to stop making the call. Whatever, it's his ship so I'll do what I'm told but I can't fathom why he didn't want me to do it, it's no skin off his back.

way to handle that situation, his ship (lol), but that doesn't mean it's the safest ship in the fleet;) good job kiddo

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

I'm in the group that considers the call to be one more chance for ATC to check his ass and make sure I'm not going to hit anyone on the way down. ATC seems to be reluctant to put anyone within 10 miles of each other (double the minimum) when climbing or descending. To me, this says something about how much I should trust the controllers.
 
I do it no matter what.

Not only does it inform ATC, but the other aircraft on your frequency that might be cruising, or climbing on altitudes that you will pass that a hunk of fast moving metal might be passing in front of them.

ATC had already giving him a specific request at pilot's discetion. but i dont really have an opinion, i say error on the side of safety unless it takes you 10 minutes to get your call in.

No offense man but if anyone said good job kiddo to me to my face I'd look them straight in the eye and tell them to f-off. It's disrespectful.
