Default IA to Class E

In fact, working the numbers, I don't see how those takeoff minimums are
possibly within TERPS limits. The 1008' tower is 4000 feet from the
departure end of the runway, 1000 feet off the extended centerline, and
550 feet above the airport elevation. I make that a 550 ft/nm climb
gradient. To put that in perspective, at 76 KIAS (Vy in an Archer or
172), you'd need a 980 ft/min climb rate to clear the tower (OK, you do
a little better at Vx). How can this be legal?


Roy: perhaps this is an oversight, with the minimums predating the
tower? Have you considered calling someone to enquire about
this?

Just a suggestion,
Sydney

Question is: is AF/D data available in a form which could
be downloaded to a Palm from some source on the web?


A quick google search for 'a/fd palm' turned up several. Plus,
AOPA has similar data available, with Palm sync capability.

BTW, you do have Copilot on the Palm, don't you?

Similar but not the same. For example, it doesn't indicate
if a given airport is class G or class E, far's I can tell.

Plus of course it doesn't have the other AF/D stuff --
preferred routes, restrictions on navaid service volume
etc.


Did you look at the others in addition to AOPA? I haven't
looked in detail, because it isn't that important to me, (my
employer supplies an A/FD and a place to keep it) but they claim
to have the full A/FD. For a price, but then everything has its
price, doesn't it?

What operational difference does that make? They're both uncontrolled,
right?

a ship, the correct assumption is *not* "gosh, I bet that's a real nice
boat now that those rats are gone". - Mike Sphar

I thought you just got your IR, Paul. Shouldn't you tell me?

If the airport is Class G, you can cancel IFR once you're clear
of clouds and have 1 mile vis below 700 AGL. This often means
you can contact ATC in the air, and they can release another aircraft
for the approach.

If the airport is a Class E surface zone, that would be a violation.
You need "152" cloud clearance and 3 miles vis, which might mean
you need to land and find a phone to cancel and meanwhile someone
else is spinning.

Of course, there might be operational reasons why you wouldn't
wish to cancel until you're on the ground regardless, but if
you're comfortable cancelling in the air, that's the operational
difference.

Cheers,
Sydney
