Ceiling
For aviation purpose, a ceiling is the lowest layer of clouds reported as being broken (BKN) or overcast (OVC), or the vertical visibility into an obscuration like fog or haze.
ceiling and visibility
The ceiling is the height ascribed to the lowest layer of clouds or obscuring phenomena when it is reported as broken, overcast, or obscuration and not classified as "thin" or "partial.
Ceiling
At a certain altitude climb performance will reach 100 ft/min on the VSI, the aircraft is then said to have reached its service ceiling. Absolute ceiling will be reached when the RoC is 0 ft/min.

ceiling - (1) The clarity of the air for looking upward, as in "ceiling and visibility unlimited." (2) The maximum altitude at which a given aircraft can be operated safely.
Ceiling: The height above the earth's surface of the lowest layer of clouds or obscuring phenomena that is reported as broken, overcast, or obscuration.
CEP: Circular error probability.

Ceiling. The maximum height to which an aeroplane can climb. The Absolute Ceiling is the height at which the rate of climb is zero and at which the aeroplane has only one possible flying speed.
POINT CEILING: A limit on the amount of points that can be earned through a specific method, such as an affinity card or a special bonus offer.
Service Ceiling

CEILING - Normal maximum operating altitude of an aircraft.
CENTER OF GRAVITY - (CQ), the point on an aircraft's structure where the total combined weight forces act.
Ceiling and Visibility: Low ceiling and reduced visibility are safety hazards for all types of aviation. Studies indicate that ceiling and visibility were cited as contributing factors in 24% of all aviation accidents between 1989 and 1997.
Hover Ceiling at Max Weight = 4000ft OGE and 6000ft IGE.
This means that the fully loaded helicopter can hover at 4000ft above the ocean (ie. no hard surfaces close below), ...
Service Ceiling: Altitude at which cabin crews can serve drinks.
Spoilers: The Federal Aviation Administration.
Stall: Technique used to explain to the bank why your car payment is late.
Absolute ceiling is the maximum altitude an aircraft can attain. At this point the cruise speed, best climb speed and stall speed all equalize. The aircraft becomes unstable and controls are unable to stabilize flight.
Ceiling: Height above the earth's surface of the lowest layer of clouds.
Ceiling Zero: Less than 50 feet from the ground to cloud base.

At about 11 PM, I was cleared for takeoff under an overcast sky with the ceiling at 900 feet. At about 300 feet, I was instructed by the tower to contact the departure control. Shortly after I contacted the departure control, I engaged the autopilot.

0 and a ceiling of 90,000 ft (27,000 m), although a specially modified MiG-25 flew to an altitude of 123,524 ft (37,650 m) in 1977.
In the following picture you can see that there are many skylights built into the ceiling of the building. This allows the workplace to be lit by natural light, saving electricity.
VFR weather minimums for controlled airspace require at least a 1,000-foot ceiling and three miles visibility except for "Special VFR" clearances to operate "clear of clouds.
While flying at its service ceiling of 35,000 feet, the PiperJet is expected to achieve a max cruise speed of 360 knots, burn 77 gph and provide a range of 1,000 nm with NBAA 100 nm reserves.
The range of the aircraft was some 620 miles and had a service ceiling of 25,400 ft. Its maximum take-off weight was 41,529 lbs, with a wing span of 137 ft, 1 in, length of 82 ft 4 in and a wing area of 2,523 sq. ft.
Now, check the weather: There should be little or no wind, good visibility (no haze) and at least a 3,000 foot ceiling. Avoid the time around sunset if your active runway is 22 to 33! And, have as few friends around as possible.
For example, when prevailing low ceilings are forecast or observed over a given area an IFR AIRMET is issued. Though AIRMETs are nominally for all aircraft, they are much more significant for small aircraft.
As soon as we went 'clocks off' (ending the exercise) I pulled off my headset, sank back in my chair and laughed at the ceiling in horror at what'd just happened. "Jesus Christ...
With Cutlass prices already bumping the ceiling of the budget-buy category, we're going to leave the more expensive 1996 and newer 172s for another day.

INSTRUMENT METEOROLOGICAL CONDITIONS (IMC). Weather worse than 1500 feet ceiling or 3 NM visibility. IMC requires use of IFR.
VISUAL FLIGHT RULE (VFR) CONDITIONS - Meteorological conditions under which VFR flight is permitted. For VFR flight certain requirements for visibility, ceilings (for takeoffs and landings), and cloud clearances must be met.
The aim of the climb performance experiment is to determine the maximum rates of climb, and the corresponding speeds at different altitudes, and to extrapolate the service and absolute ceilings for airplane.
Powered by a Rolls-Royce Griffon 65, 12-cylinder, 2,050 hp engine, it could reach a speed of 448 mph (721 km/h) and could reach a ceiling of 44,500 ft (13,560 m) and had a range of 460 miles (740 km).
