"Direct when able"
When instructed to fly a heading then "Direct XYZ when able", does a
controller expect a call when you are in fact able and will be turning on course? Usually it is a trivial turn since the heading they give is a good guess for direct course. I've had conflicting experience. One time after being told the above, I responded "I'm able to go direct now" and his ackowledgement had a "who cares? Just do it" tone to it. Just a few days ago, I made the 8 degree turn to navigate directly to the VORTAC, and when the shift change at approach took place, the new controller asked what my heading was, whether I was picking up the VORTAC, and when I told him that I was navigating direct, he seemed surprised.

Don't know if there is a "right way", but I just fly the heading until I can
navigate direct. I've never updated the controller when I'm heading direct to the waypoint unless he requested it. Michael "Mitchell Gossman" wrote in message m...

I usually tell them before I make the course change. It might be a few
minutes before I am able to go direct and letting the controller know helps ensures everyone is on the same page. jerry "Mitchell Gossman" wrote in message m...

Chip Jones wrote: No. When ATC says "Direct XYZ when able", the unsaid part of the message is that they have deconflicted you from traffic between you and XYZ. With no conflict, they don't care if you are a few degress left or right of XYZ until you find it. They know that you will be turning a bit (depending on how good the vector is) as you receive the station. The "when able" phraseology authorizes the turn. That is SO well stated. Too bad, all the FAAs can't get together and put gems like that in a guidance handbook. |

VOR/VORTAC/TACAN NAVAID's
Normal Usable Altitudes and Radius Distances Class Altitude Distance (miles) T 12,000 and below 25 L Below 18,000 40 H Below 14,500 40 H 14,500 - 17,999 100 H 18,000 - FL 450 130 H Above FL 450 100 Altitude and distance limitations need not be applied when any of the following conditions are met: a. Routing is initiated by ATC or requested by the pilot and the following is provided: 1. Radar monitoring. 2. As necessary, course guidance unless the aircraft is /E, /F, /G, or /R equipped. NOTE- 1. Para 4-4-1, Route Use, requires radar monitoring be provided at FL 450 and below to aircraft on random (impromptu) RNAV routes. Para 5-5-1, Application, requires radar separation be provided for these routes at FL 450 and below. 2. When a clearance is issued beyond the altitude and/or distance limitations of a NAVAID, in addition to being responsible for maintaining separation from other aircraft and airspace, the controller is responsible for providing aircraft with information and advice related to significant deviations from the expected flight path. |

The FAA did not write the new instrument handbook. I wrote two chapters
myself. What the FAA did, however, was to edit the text severely and force it to fit into some of their preconceived notions. I lost some good stuff during the editing process.

So the FAA would have no interest in publishing anything like it. No doubt you're right on that one. When they wrote the current IFR Handbook they ended up with some pretty big errors because the left hand didn't know what the right hand was doing. |

I tell my readers (and anyone else who will listen), that "when able" also
means "when you can proceed without hitting anything." Simply getting a good needle is not the whole story. ATC has no responsibility for keeping you out of the trees until you reach their MIA.

In a previous article, "Bob Gardner" said:

ATC has no responsibility for keeping you out of the trees until you reach their MIA. The other day I was north of Syracuse and I asked for direct Rochester (instead of flying down to Syracuse and following V2). The controller cleared me "direct when able", and when the GPS showed that I would just barely miss the restricted area (R-5203?), I turned. But evidently that was too close for her, because a few minutes later she turned me 45 degrees off my course for a few minutes before she let me turn back. I wonder if I should have said something to her about seeing the restricted area on my GPS? -- Paul Tomblin , not speaking for anybody Simulated editor war, conducted by seasoned professionals in a controlled environment.
