The flight zone is determined by the animal's flight distance, sometimes called [3] flight initiation distance (FID) [4] which extends horizontally from the animal and sometimes vertically. It may also be termed [ citation needed ] escape distance , alert distance , flush distance, and escape flight distance.
Animal navigation is the ability of many animals to find their way accurately without maps or instruments. Birds such as the Arctic tern, insects such as the monarch butterfly and fish such as the salmon regularly migrate thousands of miles to and from their breeding grounds, [1] and many other species navigate effectively over shorter distances.
Avare is a free open source "moving map" aviation GPS, A/FD and EFB app for phones or tablets using the Android Operating System.The app uses any internal Android or compatible external GPS receiver to determine location, allowing real-time display of location, heading, speed, distance, time, and altitude on free U.S. FAA IFR or VFR aviation charts; or on select topographic charts.
The wind triangle is used to calculate the effects of wind on heading and airspeed to obtain a magnetic heading to steer and the speed over the ground (groundspeed). Printed tables, formulae, or an E6B flight computer are used to calculate the effects of air density on aircraft rate of climb, rate of fuel burn, and airspeed. [9]
Although it is widely thought that Quetzalcoatlus reached the size limit of a flying animal, the same was once said of Pteranodon. The heaviest living flying animals are the kori bustard and the great bustard with males reaching 21 kilograms (46 lb). The wandering albatross has the greatest wingspan of any living flying animal at 3.63 metres ...
Critical distance for an animal is the distance a human or an aggressor animal has to approach in order to trigger a defensive attack of the first animal.. The concept was introduced by Swiss zoologist Heini Hediger in 1954, along with other space boundaries for an animal, such as flight distance (run boundary), critical distance (attack boundary), personal space (distance separating members ...

Step amplitude: the distance a leg travels during swing in a ego-centric reference frame. Step length: the distance from the stance onset to stance onset in a world reference frame. Stride range of motion: the leg's integrated path between stance onset and swing offset. Joint angles: Walking can also be quantified through the analysis of joint ...
