To answer the question in the title, the AIM 4-3-2 says:
When operating at an airport where traffic control is being exercised
by a control tower, pilots are required to maintain two-way radio
contact with the tower while operating within the Class B, Class C,
and Class D surface area unless the tower authorizes otherwise.
Initial callup should be made ...
I fly out of Addison, McKinney, Mesquite, Denton, Rockwall, Sulphur Springs and Aero Country a lot. I am also friends with the A&P located at Airpark. If you would like a safety pilot who knows the local area, maybe we can hook up.
A few things to remember when operating out of airpark:
The runway is barely maintained. But, it is not perfectly smooth. ...
Because class D is controlled airspace.
While you are correct that VFR-IFR separation is not provided in class D airspace, the major advantage compared to class E airspace is that, because VFR is subject to a clearance, ATC knows exactly where all VFR aircraft are, enabling ATC to provide very accurate traffic information and/or collision avoidance.
So why ...
If you are departing an uncontrolled airport within the surface area of a controlled airport, then you are required to contact the latter airport's control tower as soon as practical.
In the particular case of F69 and ADS, since the former is almost directly under the instrument approach path to the latter, you will also want to turn east (i.e. away from the ...
There should be no reason or need to enter the bravo.
I would listen to KADS ATIS to determine winds and direction of landing, then simply give tower a call and tell them you are inbound to F69.
For a specific example: “Addison tower, Skyhawk N123Y 10 miles northeast, information Bravo, inbound for Air Park (F69).” They will probably come back and ask you ...
Bonus question: There is a tiny sliver of class D airspace surrounding
the surface B of SeaTac on the western, southern and southeastern
parts of the bravo that is surface. Anyone know if this belongs to
SeaTac because there is no other field in the center of the area and
if so, why on earth does a bravo airport also have a tiny section of
class D ...
