There are two main algorithms, the Canadian C-spine rule and NEXUS, which are used to decide who requires cervical spine imaging via CT scan [6] after blunt trauma, and who can be cleared without imaging. [4] The Canadian C-spine rule appears to have greater sensitivity and specificity (i.e. fewer false positives and false negatives). [17]
The command for recovery is "Ready, front." If the command does not have rifles, they will salute if given the command Present arms.

Arm span or reach (sometimes referred to as wingspan, or spelled armspan) is the physical measurement of the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90° angle. The arm span measurement is usually very close to the person's height.
Using physics, math and brain science, we can come up with a pretty good estimate of proper following distance for various driving situations. Use this counting method to find safe following ...
A typical runway safety area, marked in brown color. A runway safety area (RSA) or runway end safety area (RESA, if at the end of the runway) is defined as "the surface surrounding the runway prepared or suitable for reducing the risk of damage to airplanes in the event of an undershoot, [1] overshoot, or excursion from the runway."
Determine weights and arms for all mass within the aircraft. Multiply weights by arms for all mass to calculate moments. Add all moments together. Add all weights together. Divide total moment by total weight to give overall arm. The arm that results from this calculation must be within the center of gravity limits dictated by the aircraft ...
Using table C, locate the wrist/arm score in the Y-axis and the neck, trunk, leg score on the X-axis to determine the RULA score. The RULA score is a numerical value between 1 and 7. If the RULA score returns a 1 or 2, the posture is acceptable but if the RULA score is a 7, changes are needed.
