Visual approach is an approach clearance, which means you are also cleared to
descend. No need to report leaving unless explicitly directed to do so by ATC. Dave Butler wrote: 2) Its VMC and I'm IFR to Temple, level at 5000. At 25 miles out I report Temple in sight. "N7NZ cleared visual approach to Temple, remain this frequency til you're closer in". At this point I may descend at will, right? When I do decide to descend, do I report leaving 5000? Assuming 5000 was an assigned altitude, yes. -- --Ray Andraka, P.E.

"John Clonts" wrote in message ... In answering these questions, consider these definintions from the Pilot/Controller Glossary in the AIM: PILOT'S DISCRETION - When used in conjunction with altitude assignments, means that ATC has offered the pilot the option of starting climb or descent whenever he wishes and conducting the climb or descent at any rate he wishes. He may temporarily level off at any intermediate altitude. However, once he has vacated an altitude, he may not return to that altitude. CRUISE - Used in an ATC clearance to authorize a pilot to conduct flight at any altitude from the minimum IFR altitude up to and including the altitude specified in the clearance. The pilot may level off at any intermediate altitude within this block of airspace. Climb/descent within the block is to be made at the discretion of the pilot. However, once the pilot starts descent and verbally reports leaving an altitude in the block, he may not return to that altitude without additional ATC clearance. Further, it is approval for the pilot to proceed to and make an approach at destination airport ... CLEARED (Type Of) APPROACH - ATC authorization for an aircraft to execute a specific instrument approach procedure to an airport; e.g., "Cleared ILS Runway Three Six Approach." 1) "N7NZ, cleared direct BMQ cruise 7000". Do I report subsequent descents? You may choose to report subsequent descent but you are not required to do so; if you give such a report, however, then you may not climb back again without obtaining an additional ATC clearance. 2) Its VMC and I'm IFR to Temple, level at 5000. At 25 miles out I report Temple in sight. "N7NZ cleared visual approach to Temple, remain this frequency til you're closer in". At this point I may descend at will, right? When I do decide to descend, do I report leaving 5000? You may descend when you choose to do so; there is no need for you to report leaving 5000. 3) I'm level at 7000. "N7NZ, descend 3000 pilots discretion". Do I report my descent? Can I level off at an intermediate altitude, and if so, do I eventually report leaving that altitude?E.g. "leaving 7000 descending 5000"? Then later "leaving 5000 descending 3000"? Yes, you may level off at an intermediate altitude. No, you are not required to make a report if you choose to do so. Please read the above "do I" as "am I required to". In my (small) IFR experience to this point I have made the reports in many/all the above cases, so I'm now trying to confirm which of them are unnecessary... As above, you are not required to make any of these reports. Generally it is good practice to make such reports anyway, unless the frequeny is busy, in which case the controller may not appreciate the extra reports -- that is a judgment call you can make in each situation. Note that in the case of a cruise clearance, providing such an extra report may actually result in limiting your altitude options as noted above. As a related but interesting issue, have you ever received a CRUISE clearance? If so, where did you get it and did you request it or was it assigned? I have obtained all sorts of interesting clearances from ATC, but whenever I request a CRUISE clearance the reply I usually get from ATC implies they never heard of it or at least that they never use this -- sort of like filing "OTP" for an IFR altitude although I have had some greater success there. -- Richard Kaplan, CFII www.flyimc.com |

Hello Richard, After having read that they were so rare, I got "offerred" one on my SECOND ifr flight after I got my IR last year! I had filed from KTPL (Temple) to 44TE (a grass strip about 80 nm away, elevation 900). As I recall the weather was around 4000 scattered. When I was about 30 miles from 44TE at 6000, it went something like this: CTR: "N7NZ, let me know if you need a cruise clearance" N7NZ: "Roger, N7NZ". wracks brain for implications Few minutes later: N7NZ: "Center, N7NZ request cruise clearance to 44TE now" CTR: "Roger, N7NZ is cleared to 44TE, cruise 4000. Cancel this frequency or on the ground via Flight Service" I descended into VMC and cancelled on the frequency. Though it wasn't a factor that day, I believe that in worse weather I would have then descended to the MIA (which is about 2500 in that vicinity), and if not visual by then, just climb, reestablish contact with center if necessary, and work on "plan B" which would involve an instrument approach to a nearby airport.

Something that has been missed in the responses to your post is that when
given a cruise clearance you can bob up and down between the assigned cruise altitude and the MEA without any report at all UNTIL you report leaving the assigned cruise altitude...at that point, ATC can assign 7000 (in your example) to another aircraft. Don't report leaving until you know for sure that you won't be going back up. The most practical use of a cruise clearance is when you suspect that the ride or the weather would be better at a lower altitude, so you descend without saying a word to ATC and take a look...if conditions are better, you say "Cessna blah blah requests 5000 (or whatever) as a hard altitude" and stay there. If they are not, you go back up or choose an intermediate altitude. Bottom line is that you own the block of airspace between the assigned cruise altitude and the MEA and can do whatever you want to do within that block without report UNTIL you make the report...then you have given up the cruise altitude. Read the "Cruise" definition in the Pilot/Controller Glossary. Bob Gardner "John Clonts" wrote in message ... 1) "N7NZ, cleared direct BMQ cruise 7000". Do I report subsequent descents? E.g.

I don't think I would "bob up and down" on a cruise clearance. I would request
a block altitude assignment if I want to "bob up and down." A cruise clearance is also an instrument approach clearance, so once I leave the last assigned for all I know the controller may be using my Mode C as a de facto report out of that altitude. I don't have to worry about that possible ambiguity with a block altitude assignment. And, I learned a long time ago not to buy into any situation that can become ambiguous. That doesn't help me nor does it help the controller. I can certainly descend to an intermediate altitude on a curise clearance, then level off. But, "bob back up?" not me.

With reference to using Mode C as a defacto report....
5-5-6 Exceptions {New-2003-15 a. revised August 7, 2003} a. Do not use Mode C to effect vertical separation with an aircraft on a cruise clearance, contact approach, or as specified in paragraph 5-15-4, System Requirements, subparagraph e and f. Maybe not right on point, but a suggestion that controller's do not necessarily buy a Mode C readout all the time. Bob Gardner wrote in message ...

They may buy the Mode C readout, but they can't trust the aircraft to stay at the altitude they're reading. A cruise clearance permits descending and climbing at pilot's discretion. We use it all the time in the Gulf of Mexico, for instrument approaches where we can't talk to center once we start a descent, or often at altitude. We don't often climb back up, but we might if we lose comm with both center and our company flight following, and have to climb to regain contact. On a cruise clearance, the aircraft may either climb or descend, without the controller having any control over it, thus he can't rely on the altitude readout to separate traffic. -- Regards, Stan |

That is fine if you choose not to do so, but the AIM is very clear that such "bobbing back up" is permissible. -------------------- Richard Kaplan, CFII www.flyimc.com |
