Wing Updates Flashcards
Dipping Sonar Operations 1
NATOPS dipping sonar/coupled hover procedures item 8 “establish a steady coupled hover” shall be completed prior to “DOWN DOME”. PNAC should adjust the LONG VEL and LAT VEL potentiometers to control drift and limit G/S to no greater than 2 kts (drift limits do not apply while in sonar cable angle mode)
Cable angle hover shall be operable for all dipping sonar operations. Submerged override shall not be used to routine operations.
Dipping sonar operations should not be conducted in seas with wage heights exceeding 10 feet, winds exceeding 17-21 knots, or known/discovered currents greater than 4 kts during unit level training or fleet level exercises (GRUSAIL, C2X, JTFEX, IDCERT, Submarine Commanders Course, DESIEX, INTL exercises, SHAREM, etc.). Preflight deliberate ORM and in flight time critical ORM assessments of forecasted or observed sea state conditions and currents shall be accomplished prior to dipping sonar operations.
If cable angle exceeds the 4.25 degree inner ring, all crew members shall verbally acknowledge the deviation and ensure appropriate corrections are being made to center the cable.
Dipping Sonar Operations 2
During dipping sonar training operations (with or without a submarine) POCL shall be no more than half the ceiling up to 1000 foot ceilings. When ceilings are above 1000 feet, POCL shall be no more than 500 feet below the ceiling. During operational ASW involving a submarine, under conditions that preclude a free stream recovery, then POCL need not be restricted. However, ORM shall be conducted to minimize the risk to the TA in the event of a malfunction.
Dipping sonar operations are prohibited with AFCS degradations affecting automatic approach, coupled hover, or cable angle hover functions. Cease dipping operations following any uncommanded pitch changes in a hive until MX action is performed.
With an 1177 fault (to include on MBIT), cease dipping operations until MX action is performed.
If TA towing G/S limits are exceeded, cease dipping operations and document on a MAF.
While operating in a squadrons local area for ULT, an ACTC LVL III SO shall be in the helo on any flight in which dipping is intended. For fleet level exercises, an ACTC LVL III SO should be in the helo on any flight in which dipping is intended to the maximum extent practicable.
Post Installation MX Dip
Post installation MX dips from shore shall be conducted in an area with no more than 2000 feet of water depth to facilitate recovery efforts in the event of loss of TA. For SOCAL operations, post installation Mx dips shall be conducted in IB dip area Charlie.
Radius of Action
Shipboard radius of action is 150 NM or max reliable comm/nav range, whichever is less. Radius of action beyond 150 NM in support of specific operational or tactical training missions may be approved by ISIC when dictated by mission planning, provided deliberate ORM has been conducted. Time spent beyond 150 NM shall be limited to the minimum required to accomplish mission objectives.
One way flights shall be limited to 150 NM ship to ship and shore to ship and 200 NM ship to shore. Ship to shore range is a point at which a safe landing can be made.
