1,000-foot ceiling and 3 miles visibility.
The minimum ceiling requirement for VFR (Visual Flight Rules) operations in Class C airspace is typically 1,000 feet above ground level (AGL) for cloud clearance and visibility. Pilots must maintain at least 3 statute miles of visibility and remain clear of clouds, with specific requirements for distance from clouds (500 feet below, 1,000 feet above, and 2,000 feet horizontally). It's essential for pilots to check the specific regulations and any local amendments that may apply.

From a practical standpoint, yes. AIM 7-1-31 says, "For aviation purposes, the ceiling is the lowest broken or overcast layer [of clouds], or vertical visibility into an obscuration." It goes on to explain that vertical visibility is an indefinite ceiling height where total obscuration is indicated. That said, 14 CFR 1.1, under "ceiling", makes no mention of vertical visibility.
The blue box with number on the VFR terminal area chart is the ceiling of class D airspace in hundreds of feet ( A minus ceiling value indicates surface up to but not include that value.)
The different types of controls available for operating ceiling fan remotes include handheld remotes, wall-mounted remotes, and smartphone apps.
Ceiling 1,000 feet overcast and 3 to 5 statute miles visibility.(Refer to figure 16.
A universal light kit for a ceiling fan provides additional lighting to the room and can be easily installed on most ceiling fans. It offers the benefit of improved visibility and aesthetics, enhancing the overall functionality and appearance of the fan.
The operating ceiling (maximum height) for an Airbus A380 is 43,030 ft.
Most helicopters out there do not have pressurized cabins so the general service ceiling for helicopters today is 10,000 ft. So to answer your question anywhere from 0-10,000 ft. depending on airspace regulations.
