well this goes back to my flight back last year when even though the active runway is 24 (24/06) Cebu Pacific (cheapest airline) usually takes off at runway 13 under runway designation (13/31)

There are several reasons an aircraft may take off on a runway other than the "active" runway. Everyone must observe the wind direction to some extent - to stay within the crosswind limits of the airplane (the maximum side wind allowed for takeoff and landing - usually dependent upon weather , IE. fog, rain, ice, snow). Sometimes if the wind allows it, an airplane must change runways because the length of the "active" runway is too short, or too narrow, or the aircraft cannot maneuver onto the runway. Sometimes certain types of airplanes have to use specific runways due to noise or performance requirements (IE Concorde (noise)). Sometimes airplanes are allowed to use "nonactive" runways to save time and taxi fuel (closer to departure gate). Usually air traffic control does not allow much variation if there is much departure or arrival traffic. But departure delays for use of a "nonactive" runway can occur in many of the cases cited above.

It has everything to do with what's going on at the airport at that particular time. Could be due to traffic, wind direction, dot dot dot. (planes always try to take off into the wind) Inactive doesn't mean it's closed. I did flight training at Class B and C airports. Class B airports are generally high volume, C are busy too but to a lesser extent. When I would practice touch and go's (or go to practice them still today) I'm usually put on one of the smaller runways not in use by the big boys.
Just to let you know runways are named for their compass headings. Runway 13 is about 130 degrees and the opposite direction is runway 31 (~310 degrees)

The designated "Active" runway is normally the one closest to the direction of the current winds. At airports with only one ILS runway, then the "Active" runway is usually the one with the ILS approach.
If the winds are calm, then it really doesn't matter which runway is used for takeoff. Some pilots may choose to use the runway that is most in line with their intended direction of flight, so they can climb out directly towards their destination instead of having to circle the airport.

The "active" runway is the one designated by ATC for an aircraft to use. If ATC says use 13/31, it then becomes the active runway, if only for one takeoff.

If that's a question about takeoff as against landing, airplane in a lot of cases choose more advantageous runway to take off than to land. you're placing out out at 0 floor speed. The flaps/slats on the wings are used to grant more advantageous strengthen to get the airplane off the runway quicker. Then, after takeoff, the flaps/slats are stowed because at the same time as prolonged, they carry drag as well as more advantageous strengthen. So inflight, the airplane is in a "clean" configuration permitting it to fly faster. landing will be executed in a a lot shorter distance because now you've complete flaps and slats prolonged, thrust reversers, and brakes to quit the airplane. One a facet word, airplane infrequently use complete capacity for takeoff. except the airplane is at or on the point of max gross takeoff weight for a particular runway, airways opt for to apply decreased thrust to keep placed on and tear on the engines. This thrust help will be small, or as tremendous as 20%!. that's why, from time to time, apparently like a smaller jet (737 vs 747) takes up the total runway to take off.

It is not inactive if someone is taking off or landing on it. At a controlled airport, pilots can request what ever runway they want.

Small planes can utilize shorter runways and land with less effect to the traffic pattern...? Only a concern at larger airports.
Would seem strange though.

They don't. If they land/tkof on a R/W it is active.
As we say in ATC, ALL R/W's are active. The one you are using is the "R/W in use"
