Message: [QUOTE="avbug, post: 11509, member: 1312"] Eagleflip, Gravity doesn't neceesarily "fall," but at lesser elevations or distances from the earth's center, it affects a "falling" object with an acceleration of 32.2 feet per second, per second. (or 32.2 feet per second squared). Traffic lights know you're coming because you look at them. Try looking somewhere else, such as looking at a cross street as though you intend to turn. You may be surprised how many more lights you can go through. Traffic lights in most systems are tied to timers which do vary with the time of day, and traffic density. The timers are generally designed to allow a vehicle moving at a specific speed to move from one light to the next with a certain amount of leeway. The timing is altered when numerous cars in "wolf packs" (the traffic terminology, not mine) change the traffic flow rate. Traffic lights are tied into opposing lights on the same intersection, and often on other intersections. These lights change their timeing due to traffic presence and counters using either weight pads or in most cases magnetic detectors implanted in the pavement just prior to the crosswalks. Light timing in one direction on a particular street may be changed or altered, and thus the pattern of the lights on that street, by opposing traffic counts or waiting traffic on the detectors. FYI, most large cities have gone to laser and electronic systems for the lights for use by emergency vehicles, to change the light timing and effect a "green light" as the emergency vehicle approaches the intersection. This is done to expedite the emergency vehicle, and also to clear opposing traffic to lessen the chance of an accident. In some cases, it's done just the opposite. All lights turn red, stopping traffic and clearing the intersection, for emergency vehicles to get through. I suggest just looking the other way; never let the light see you looking at it. Only Bobbysamd can tell you about the Broncos. That's a sport's team, right? Or are you talking about the ubiquitous OV-10D? Stall speed increases in the turn because a higher angle of attack, for a given airspeed, is required to achieve the same vertical lift component, as previously described. You can either increase total lift by increasing airspeed, or angle of attack (or both). In a level turn with no speed increase, one can only increase angle of attack. Therefore, the aircraft is closer to a stall, or it will stall at a higher speed. However, stall speed may increase climbing and descending, not just level turns. The degree to which it increases will depend on the load factor induced. The lesser the load factor, the lesser the increase. (for a given airspeed). The number of variables increases, but the principle remains the same. Ultimately, the recovery remains the same. Get out of the bank, recover your "lost" lift. Lower A0A required, lower stall speed.
