How does airspeed affect rate of turn?
Radius of turn is dependent on both airspeed and bank angle. The radius of turn at any given bank angle is directly proportional to the square of the airspeed. Doubling the airspeed results in a radius of turn that is four times greater while tripling the airspeed would result in a radius that is nine times greater.
What is a constant rate turn?
During a constant-bank level turn, increasing airspeed decreases the rate of turn, and increases the turn radius. A rate half turn (1.5° per second) is normally used when flying faster than 250 kn. The term rate two turn (6° per second) is used on some low speed aircraft.
How is ground speed maintained with constant TAS?
At all times, you will maintain a TAS of 200 kts, and the ground speed after the turn in the first case is only 193.6 kts. In the second case, you start with a TAS of 250 kts and maintain that over the full turn. Your ground speed after having achieved a northern track is now 242 kts.
What happens if you maintain a constant bank angle?
If you maintain a constant bank angle (30 degrees for a 1.15 g turn) and maintain constant true airspeed of 200 Knots, your path will be as shown in the chart by the yellow line. If you maintain a constant ground speed (150 knots) and a constant acceleration 1.15, then your path will be as described by the grey line.
What happens if you maintain a constant ground speed?
If you maintain a constant ground speed (150 knots) and a constant acceleration 1.15, then your path will be as described by the grey line. It will be as if there is no wind, however it requires thrust variations and bank angle variations.
The quantity α, which is equal to the ratio v1 / c where v1 is the velocity of the electron in the first circular Bohr orbit and c is the speed of light in vacuum, appeared naturally in Sommerfeld’s analysis and determined the size of the splitting or fine-structure of the hydrogenic spectral lines.
