4.12.4 Litter Platforms. There are a total of four plat-forms installed in the aircraft, two at each station (Figure 4-23). The platforms provide a loading surface for a patient strapped to a litter. The litter is secured to the platform by means of a locking device mounted in the end of the plat-form and two restraint belts. The platforms attach to the support rods and are raised, lowered, or tilted by the lift mechanism. The platforms are similar in construction, with the exception that the upper platform may be recon.gured to provide seating for three ambulatory patients.
