(1) For day operations—1,000-foot ceiling and one-mile visibility. (2) For night operations—1,000-foot ceiling and two-mile visibility.

Standard takeoff minima are one statute mile for aircraft having two engines or less and one-half statute mile for aircraft having more than two engines. Specified ceiling and visibility minima will allow visual avoidance of obstacles during the initial climb at the standard climb gradient.
If the visibility is less than 3 statute miles but not less than 1 statute mile during night hours and you are operating in an airport traffic pattern within 1/2 mile of the runway, you may operate an airplane, powered parachute, or weight-shift-control aircraft clear of clouds.
(a) Except as provided in paragraph (b) of this section, regardless of any clearance from ATC, no pilot may takeoff or land an airplane under VFR when the reported ceiling or visibility is less than the following: (1) For day operations—1,000-foot ceiling and one-mile visibility.
VFR cruising altitude rules in the US and CanadaOn a magnetic course of 0-179 degrees shall fly at an odd thousand ft MSL altitude +500 feet (e.g., 3,500, 5,500, or 7,500 ft); or. On a magnetic course of 180-359 degrees shall fly at an even thousand ft MSL altitude +500 feet (e.g., 4,500, 6,500, or 8,500 ft).
The easiest way to find if an airport has takeoff minimums is to look at an approach chart. On the FAA charts, you will see a black triangle with “T” in it which is often called the “troubled T.” It's troubling because there is something, most likely terrain, keeping pilots from executing a leisurely climb.
Class D. IFR and VFR flights are permitted and all flights are provided with air traffic control service, IFR flights are separated from other IFR flights and receive traffic information in respect of VFR flights, VFR flights receive traffic information in respect of all other flights.
The lowest routinely used takeoff visibility minimum is 600 feet RVR, which is about one-tenth of a mile. Pretty low. It's the lowest visibility typically used in simulator training for taxi and takeoff practice.
Takeoff Alternate RequiredIf weather above takeoff minimums but below authorized IFR landing minimums must have an alternate airport within 1 hour's flying time (at normal cruise speed in still air) of the departure airport.
The Twelve-Five Standard Security Program (TFSSP) outlines requirements for FAA Part 135 certificated carriers offering commercial air transport using aircraft with a maximum certificated takeoff weight between 12,500 pounds (5,670 kg) and 100,309.3 pounds (45,500 kg).
A visual flight rules (VFR) aircraft on a long, straight-in approach for landing never enters the traffic pattern unless performing a go-around or touch and go after landing (see paragraph 9.5). referring to the AIM and the PHAK.
Prudent pilots typically set higher weather minimums for night VFR flights. FAR 91.157—In order to get a Special VFR clearance at night, you must have an instrument rating, an instrument-equipped airplane, 1 mile visibility, be able to remain clear of clouds, and a Special VFR clearance from air traffic control.
The VFR Cruising Altitude rule does not apply below 3,000 feet AGL. There are some altitudes, however, that pilots seem to choose for level flight. Close to sea level they are 1000, 1500, 2000 and 2500. They are easy to read and remember on an altimeter.
In aviation medicine, the 1% rule is a risk threshold that is applied to the medical fitness of pilots. The 1% rule states that a 1% per annum risk (See also risk management) of medical incapacitation is the threshold between acceptable and unacceptable.
