Can ATC assign an airway if filed direct?

I've noticed that! A couple times in the last 5 years I've been told
to go direct to an NDB. I don't have anyway to find NDBs (well, ok
GPS, but otherwise... ) Do you think there will be a formal
"forgiving" of the NDB assumption by the FAA or will it just become
another GPS waypoint?


I see no need for any change. GPS is a perfectly acceptable means of
navigating to an NDB. There's no need to advise ATC that you don't have
ADF, simply acknowledge the instruction and proceed direct via GPS. The
only shortcoming is you can't use GPS to fly a straight NDB approach.

The national airspace system is still predicated upon VOR being the primary,
non-radar en route navigation system. That will change, but it hasn't yet. The
section in part 91 that requires you to have equipment appropriate to the routes
to be flown presumes VOR equippage. No, it doesn't say that, because such is
the way of many FARs. You either comply with the obvious or you have to be armed
with all the countless policy documents with which the FAA operates.

For whatever it's worth, following is from Pargraph 813 of FAA Order 8260.19C,
Flight Procedures and Airspace, the gudiance material for instrument procedures
designers:

.. "Dual Minimums. Dual minimums, when authorized, shall be entered in boxes
constructed below the preprinted minimums section. Dual minimums shall not be
authorized unless a 60 foot operational advantage is obtained or a reduction in
visibility can be achieved. To avoid proliferation of dual minimums, all IFR
aircraft are assumed to have at least one VOR receiver. Dual minimums based on a
stepdown fix combined with local and remote altimeter settings could result in
four sets of minimums. However, only two sets of minimums shall be published on
the 8260 forms. The combinations authorized a minimums with and without a
stepdown fix; or minimums with local and remote altimeter settings."

This is available on the Summit Aviation Reference Library.

If you file to a VOR direct, can ATC clear you along an airway
instead, and expect you to look up the airways? In other words, how
important is to carry an enroute chart if you don't plan on using
airways?

ATC, to the best of my knowledge, can clear you anyway they'd like. I'm
fairly sure you're not all that legal flying IFR without the appropriate
enroute chart. You're surely not safe. How would you know the MEA/MOCA
altitudes?

Surely if you can afford $XX/hour for the plane you can spring for the
chart.

I have software for my PDA that does all that now.

What PDA and software are you using and how do you like it?

I use NavGps. You type in your cleared route, using airways if that's
how you were cleared. After hitting enter the software adds in all the
intersections. On the main map page the software gives you total
distance as well as leg distance. It's simple to remove or add fixes as
your flight plan gets ammended along the way. It draws the extended
centerline of any runway. You can select as a destination the approach
end of any runway. It has ground data like roads, rivers, obstacles
etc. I haven't flown behind it much but so far I like it.

You're joking, right?

ATC can give you any clearance they want. You don't have to accept it,
and can't if you don't have the equipment to fly it (i.e. route requires
DME and you don't have DME). But, you'd look pretty stupid saying,
"unable airways, negative chart".

No, I am not joking. Let me put the question differently. Does ATC
always assume that you have a VOR receiver and the ability to fly
airways? Since there is no specific equipment suffix for a VOR, it
appears to me that they expect all aircraft to be equipped with a VOR
receiver unless we tell them otherwise.

Ah, that's a slightly different question. I recoiled at your idea of
not carrying an en-route chart.

It is certainly legal to fly IFR without a VOR receiver, but it's pretty
much taken for granted that you've got one. It's certainly taken for
granted that you've got a chart!


Yes, that is what I thought. ATC expects you to have a VOR and
navigate along airways even though neither one is legally required. So
we agree on that.
