Sectional Question

Mon Jan 15, 2001 9:57 am

I know that I should know this, but I don't. I've looked everywhere for the answer to this question and I haven't found it.

I thought that someone could help me here...

What does it mean when the airport name is underlined on a sectional chart?

The only names I see underlined on my charts are the names of cities around the Phoenix terminal area, not airports.

If underlined, it isn't necesarily an airport (although it could be) but is rather:

(1). A Visual checkpoint--it should be associated with a golf pin type flag.

or reaching rather deep...

(2). The underlining of a frequency in a VOR/DME box indicates that the frequency is not for voice com.

Those are the only two underlinings you will encounter on a sectional.

In addendum (I don't want to start another topic with a similar name)...

If you're an airline pilot, do you usually carry (or consult) a section when flying across the continental US to get a better picture of the terrain?

P.S. Thanks for the responses, by the way!

How is it you can criticize an NWA flight crew, but you need help reading a sectional? LOOK IT UP...

Aren't you the guy that blasted military pilots re: TCAS and thought the NAV flew F-15s?

Let's see...NEIL HARRISON, 20 something, aviation expert...

Well uhhh... To answer your question:

No airline pilots do not carry sectionals. Instead, they use Jeppsen Hi Altitude Airway Manuals. These have all high altitude jet airways, VORs, Airports, etc... They also have MEAs, or "Minimum Enroute Altitudes" which let the pilots know where the highest terrain is on their route.

Well, Mcomess that´s not all corect, you said there.
On High altitude charts there are no MEA printed down. That wouldn´t make sence, since you already very high, because here in Europe the high altitude charts start at FL 240. But it´s from country to country different! So if your are using an high altitude chart you have to fly over FL240. So you will never care about the MEA, because you will always fly high enough!
Only in one case: emergency! For that reason we have also the low altitude charts on board! It´s also on our company flight plans.
I miss the MEA on high altitude charts tough!
Sometimes I bring a sectional chart with me, specially when we fly very low over the alps!!! That´s awsome!

yes i can handle that alone. - - -famous last words

I was only asking because I saw in "Cast Away" that one of the jumpseating pilots had plotted out their position on a sectional (I know that no one would have taken the time to plot out a position anymore).

I was also wondering because my instructor said it's always a good idea to have a sectional with you whenever you're under instruments for better situational awareness. This would include terrain, towers, and other land-based objects. The enroute maps don't show these things. What they do show is MOCAs, MEAs, and other such information; those are all just numbers. The sectionals show topographical information, which is extemely useful (I've found).

Back to my original question and to retort to my "enemies" (for lack of a better word)...

I asked the original question because it was a trivia question in my weekly airport newsletter.


I have never claimed to be an "expert" and I hardly am. I have said things that I regret saying on this forum, but I've said them and I offer no appologies for saying them because they're my opinion and I will stick those things. Many may not agree with me, but such is life. I do however take full responsibility for it.

Now... at least I put my name down and my full personal information as I don't attempt to 'hide' behind a username on an anonymous internet bulletin board. While I could, I believe this to be a cowardly act.

Please if you're going to bash me for no good reason, sign your name so I can address you formally.

Identifying yourself on this forum has nothing to do with it. It's about having to regret things you've said...

But since you have, and want some kind of credit for it, let me just say again that the airplane business is a small world...
