City controlled airspace?

I stumbled upon the Aircraft and Airports section of the Dallas City Codes
and found a whole new layer of regulations I never knew about.

Here's a good one. As a student, I guess I need to call my instructor
every time I need to start the engine:

SEC. 5-24. ONLY PILOT OR COMPETENT MECHANIC TO RUN ENGINE.
No person shall start or run aircraft engine other than a licensed pilot or
a competent mechanic in the cockpit attending the controls. (Ord. Nos.
8213; 14384)

The middle rings of the DFW class B airspace begin at 2500 and 3000 feet.
This one makes it pretty tough to squeeze in the

SEC. 5-36. FLYING AT LOW ALTITUDE; PERMITS FOR LANDING PLACES.
No person shall fly any aircraft over the city at a lower altitude than
2500 feet from the surface of the earth

Here's a useless one:

SEC. 5-18. TAKE-OFF AND LANDING DIRECTION.
All aircraft take-offs and landings by pilots shall be in the direction
indicated by the airport wind direction indicator unless otherwise
authorized by the airport control tower. (Ord. Nos. 8213; 14384)

I guess you have to trust the force between the hours of 12:00 midnight and
6:00 a.m:

SEC. 5-25. MAINTENANCE RUN-UPS.
No person shall start and run up an aircraft except in a place designated
for such purposes by the director of aviation or one of the director's
assistants, and such activity shall not be conducted at Dallas Love Field
or Dallas Executive Airport between the hours of 12:00 midnight and 6:00
a.m.
