    Why do you say that? It would visually, like a visual approach. I get what you're implying though I think. Make it mandatory for ATC to point them (towers) out?

    I've also heard ATC querying about being familiar with obstacles or having them in sight. Not in the .65 but not everything controllers do for us is.

    That isolated 4,400 MVA sector is there because of an antenna farm. Three of the antennas are over 1,000 feet, agl, located on terrain that is more than 700 feet higher than the airport. The distance to the airport is approximately 10 miles. Seems like significant obstacles that should be pointed out when the visual clearance is issued in the highest MVA sector.

    Yes it a mountain ridge, and I think it's closer than 10 miles to the airport but not positive about that. BHM vectors planes coming from the east on a right downwind east of the towers for runway 6. Of course not a factor if IMC as they'll be at a safe altitude. As I mentioned BHM does point it out for VFR aircraft and IFR doing visuals.

    Yah, very common coming in on VFR Flight Following to the DFW Bravo from the Southeast to have them confirm "familiar with the Cedar Hill Towers."

    And in case you've forgotten, they are a test question for the PPL. That's not the familiarity they are asking about ;)

    Those things are scary in VMC and at night. Which is why I am sooooo happy that the DODJE5 arrival and the vectoring at the end of that arrival keeps us well, WELL away from those monsters.

    And there are similar towers in Houston when on the approach to the main arrival runway for Hobby (HOU)

    Picking at nits: 10.65 miles from the tallest antenna to the approach end of Runway 3.

    Tallest antenna:

    That’s nothing. The wind farms to the west and to the north are a sea of blinking red lights. I still can’t decide if wind farms blinking in sync is better or worse than each turbine blinking on its own.

    S.V. can be a real life saver with big antennas. This is a screen shot of the KBIS antenna farm.
