ROT
From Wikipedia, the free encyclopedia
The aviation term ROT stands for rate one turn, also known as a standard rate turn, in which the aircraft turns by 3° per second (= 180°/minute). A rate one-half turn (1.5° per second) is normally used when flying faster than 250 kt. The term rate two turn (6° per second) used on some high speed aircraft.
A 3° per second turn is also called a standard rate turn.
Angle of Bank formula
The formula for calculating the angle of bank for a specific True Airspeed (TAS) is:
where r is the radius of the turn and g is the acceleration due to gravity. For a rate one turn and velocity in kt (nautical miles per hour), this comes to
.
A convenient approximation for the bank angle in degrees is
Radius of Turn formula
One might also want to calculate the radius of a Rate 1,2 or 3 turn at a specific TAS.
