A standard rate turn is defined as a 3° per second turn, which completes a 360° turn in 2 minutes. This is known as a 2-minute turn, or rate one (180°/min). Fast airplanes, or aircraft on certain precision approaches, use a half standard rate ('rate half' in some countries), but the definition of standard rate does not change.
Rate of turn indicator or ROTI on board vessels indicates the rate a ship is turning. It indicates the rate a ship is turning in degrees per minute (°/min) . It is one of the most important instruments a helmsman can have when steering a course. It can also be used to turn at a steady rate of turn, which is very important in pilotage water.
In aviation, the turn and slip indicator (T/S, a.k.a. turn indicator and turn and bank indicator) and the turn coordinator (TC) variant are essentially two aircraft flight instruments in one device. One indicates the rate of turn, or the rate of change in the aircraft's heading; the other part indicates whether the aircraft is in coordinated ...
Altitude envelope (H-M diagram).Contour is load factor. Turn rate envelope, described in an E-M diagram (doghouse plot). Contour is specific excess power. A doghouse plot generally shows the relation between speed at level flight and altitude, although other variables are also possible.
The inventory turnover ratio, also sometimes called stock turns or inventory turns, helps retailers monitor and manage inventory. ... Continue reading ->The post How to Calculate Inventory ...
A roll disturbance induces a roll rate which is only canceled by pilot or autopilot intervention. This takes place with insignificant changes in sideslip or yaw rate, so the equation of motion reduces to: =. is negative, so the roll rate will decay with time. The roll rate reduces to zero, but there is no direct control over the roll angle.
Thus the optimum rate of twist for this bullet should be approximately 12 inches per turn. The typical twist of .30-06 caliber rifle barrels is 10 inches per turn, accommodating heavier bullets than in this example. A different twist rate often helps explain why some bullets work better in certain rifles when fired under similar conditions.
The tighter the turn radius attempted, the more drag induced; this requires that power (thrust) be added to overcome the drag. The maximum rate of turn possible for a given aircraft design is limited by its wing size and available engine power: the maximum turn the aircraft can achieve and hold is its sustained turn performance.
