(£) The nurmal method of marklngwater LZ's la to align three marker eUtlon» along the left edge o( the landing strip. Station "A" la positioned at the downtv.nd (>nd of ihi» strip and Indicates the desired touchdown point. Station "ll" rKurki the last point at which tho nlrcrn't cun touch dr>wn and complete a sale landing. Station "W* Is also tlie location of the RCL and Ihe pickup point. Station "C" marks the upwind extremeof the landing area. At night, BtHtlona "A," ••B," urd "C" are marked by white lights. The KCL signal light la graen.
(3) An alternate method la to use a Bingle marker station, marked at night with a steady light In addition to the signal of recognition light. This station Is located to allow a clear approaoh and takeoff In any direction. The pilot ;e responsible for selecting the landing track and may touchdown on any track 1.000 feet (305 meters) fren» the marker station. Following pickup, the aircraft taxla b«ck to the 2/)00-foot (f.10 meters) circle In preparation for takeotf. (l*lgurc IP).
(1) Before the landing operation. theLZ 1b carefully cleared of all floating debrla. Also, the marker stations are properly aligned and anchored to prevent drifting. In Jeep or rough water. Improvised sea anchors may be used.
(2) The procedure for displaying the LZ markings and Identification Is the »»me as for operations on land L¿*b.
(3) Personnel and/or cargo to be evacuated are positioned In the RCL boat. Following the landing run, the aircraft turns to the left and taxis back to the vicinity of the RCL boat to make the pickup. The RCL indícales his position by shining the signal light In the direction of the aircraft and continues to shine his light until the pickup Is completed. Care must be taken not to hllnd the aircrew with tilia light and It should not l>e aimed directly Into the cockpit.
(4) The BCL boat remains stationary during pickup operation*. Tbe aircraft taxis to within 50 to 100 feet (15 or 50 meters) of the RCL boat, playing oat a dragline from the left Tear door. The dragline la approximately IM feet (45 metere) in length and baft three life Jackets attached; one close to the aircraft, a second at midpoint, andths third on the extreme end of the line. The life Jackets have email marker lights attached during night operations. The aircraft taxis to the left around the RCL boat, bringing the dragline close enough to he secured. The RCL fastens the line to the boat Due to the danger of swamping the craft, the RCL <toe* not attempt to pull on the line. Members of the aircrew poll the boat to the door of the aircraft Should the boat pass the aircraft door a»d nontinne toward the front of the aircraft, all personnel In the boat must abandon Immediately to avoid being hit by the propeller.
(5) After pickup, the aircrew la given any Information thai will aid In the takeotL Following this, the RCL boat moves a safe distance from the aircraft and signals the pilot "all clear." At this time, JATO bottles may be oaed lor poeltiv* takeoff power. The lnetallatlon of JaTO bottlee is time oonsuming and should not be done unless absolutely neceeaary,
(9) Helicopter* can land in eqolpaaeat provided:
rater without the use of special flotation
<a) The water depth doee not exceed 15 Inches.
(b) There is a firm bottom such as gravel or sand.
(!) landing pads can be prepared on mountains or hillsides by cutting and filling. Caution must be *x*rcl*ed to Insure there 1* adecúate clearance for the rotor*.
(1) There should be at leas tone path of approach to the L2 meters In width.
