plane.
2.9. "Oversteer" means a condition in which the vehicle's yaw rate is greater than the yaw rate that would occur at the vehicle's speed as a result of the Ackerman steer angle.
2.10. "Side-slip or side-slip angle" means the arctangent of the ratio of the lateral velocity to the longitudinal velocity of the centre of gravity of the vehicle.
2.11. "Understeer" means a condition in which the vehicle's yaw rate is less than the yaw rate that would occur at the vehicle's speed as a result of the Ackerman steer angle.
2.12. "Yaw rate" means the rate of change of the vehicle's heading angle measured in degrees/second of rotation about a vertical axis through the vehicle's centre of gravity.
2.13. "Peak braking coefficient (PBC)": means the measure of tyre to road surface friction based on the maximum deceleration of a rolling tyre.
2.14. "Common space" means an area on which more than one tell-tale, indicator, identification symbol, or other message may be displayed but not simultaneously.
2.15. "Static stability factor" means one-half the track width of a vehicle divided by the height of its center of gravity, also expressed as SSF = T/2H, where: T = track width (for vehicles with more than one track width the average is used; for axles with dual wheels, the outer wheels are used when calculating "T") and H = height of the center of gravity of the vehicle.
  3.  Application for approval
3.1. The application for approval of a vehicle type with regard to ESC shall be submitted by the vehicle manufacturer or by his duly accredited representative.
3.2. It shall be accompanied by the under-mentioned documents in triplicate and by the following particulars:
3.2.1. a description of the vehicle type with regard to the items specified in paragraph 2.2. above. The numbers and/or symbols identifying the vehicle type and the engine type shall be specified;
3.2.2. a list of the components, duly identified, constituting the ESC system;
3.2.3. a diagram of the assembled ESC system and an indication of the position of its components on the vehicle;
3.2.4. detailed drawings of each component to enable it to be easily located and identified.
3.3. A vehicle, representative of the vehicle type to be approved, shall be submitted to the Technical Service conducting the approval tests.
              4. Approval
4.1. If the vehicle type submitted for approval pursuant to this Regulation meets the requirements of paragraphs 5., 6. and 7. below, approval of that vehicle type shall be granted.
4.2. An approval number shall be assigned to each type approved, its first two digits shall indicate the series of amendments incorporating the most recent major technical amendments made to the regulation at the time
