Q

VERTREP can be used to a distinct advantage by

A

Eliminating the approach, hook up, and disconnect time required in an alongside transfer. This is particularly true during small scale replenishments where less than approx 75 short tons are to be transferred.

Q

Course change

A

Pilots conducting VERTREP shall be notified prior to any course change. VERTREP operations may be continued through the turn provided the aircraft commander and HCO deem such operations to be safe.

Q

Winds

A

Optimum: 330-030
Acceptable: 270-090
Not recommended: all others

19
Q

Privileged aircraft

A

With external load

Should have right of way to most direct route from flight deck to flight deck

20
Q

Burdened aircraft

A

Without external load

Maneuvers outside and clear of privileged aircraft.

21
Q

VERTREP distance limitation

A

Carrying external loads for long distances (over 35 miles for heavy, high density loads and over 25 miles for light, low density loads) should not be considered standard VERTREP procedure

22
Q

Overfly ships

A

Aircraft with an external load shall not overfly ships unless operational necessity so dictates.

23
Q

Ship stationing during unrep

A

During unrep, wave reinforcement phenomena caused by two ships in proximity may generate disproportionately large waves in moderate sea states. Although wind and deck conditions may be within limits, the possibility of aircraft being struck by a wee while on deck shall be considered before positioning an aircraft on the flight deck or conducting flight operations during UNREP

24
Q

Pilot endurance

A

During day VERTREP 6-8 hours is generally accepted as an effective limit of pilot endurance.

During night VERTREP effective limit may be reduced to as few as 2 to 3 hours

25
Q

Methods of load pickup

A

Method I - hookup man raises the pendant. Slips eye over helicopter hook, then clears the area

Method II - hookup Man hands pendant to the aircrewman positioned in the charge access door

Method III- hookup man holds the pendant up until the aircrewman in the open carve access hatch guides the pendant onto helicopter hook

26
Q

Night VERTREP decision

A

The final decision regarding whether a certified ship is to conduct night VERTREP at night shall be left to the pilot in command

27
Q

Night VERTREP ships

A

Ships that are certified class I or class II or are operating under a waiver

28
Q

Night VERTREP required conditions

A

One or more of the following conditions shall exist prior to conducting night VERTREP to appropriately certified ships:

  • a natural visible horizon is present.
  • the drop/pickup zone of the ship to be worked is clearly visible from the aircrafts cockpit whenever the drop/pickup zone of the transferring/receiving ship
29
Q

Submarine VERTREP decision

A

The final decision as to the feasibility and safety of the operation rests with the pilot in command.

30
Q

Attack submarines VERTREP

A

VERTREP may be conducted on attack submarines during day VFR conditions. The drop zone shall be agreed upon and briefed between the VERTREP control officer and the pilot.

31
Q

SSBN/SSGN submarines

A

Day VERTREP operations are feasible on a routine basis. Night VERTREP operations are considered feasible on a more limited basis.

32
Q

SSBN/SSGN Submarine winds

A

Magnitude of wind very the deck should be no greater than 20 knots

Headwind component

Ideal winds a are relative at 10-40 degrees on the port bow with wind magnitude between 10-20 knots

33
Q

SSBN/SSGN VERTREP area

A

Rectangular on the main deck aft of the sail should be outlined with a 4-in wide high visibility tape (missile hatches 17-20)

34
Q

SSBN/SSGN VERTREP personnel and communications

A

First lieutenant, LSE, and transfer petty officer aft of the sail

Communications conducted prior to commencement, should not during actual hovering phase

35
Q

Cabin seating in VERTREP configuration

A

Up to five cabin seats may be installed in the logistics/VERTREP or SAR/MEDEVAC configuration. A maximum of four seats may be occupied in any configuration. Litter installation prevents use of SO console seat and instructor seat.

The center rear seat shall be removed if conducting VERTREP

36
Q

VERTREP qualification

A

Initial - four field VERTREP practice evolutions or four day shipboard VERTREP evolutions.

Evolution - approach, pickup, transport, and drop off of a practice external load to a simulated or actual ship deck

Maintain currency - four day field or shipboard evolutions in the last 365 days. Initial shall be completed if expired.

37
Q

Night WARNING for VERTREP

A

Night shipboard external cargo operations present serious hazards to personnel and equipment and shall not be conducted except for reasons of operational necessity

38
Q

VERTREP BRIEF

A 
Ship certification/deck utilization 
VERTREP patterns
Come/visuals signals
1. Wave off
2. Fouled deck/load
External load hookup/release
External load flight (airspeed/angle of bank)
Emergency procedures
39
Q

VERTREP checklist

A

DO IT

40
Q

VERTREP power margin

A

A minimum power margin of 6 percent torque shall be required prior to commencing each VERTREP evolution

SOP: when conducting vertical replenishment operations, a 10 percent power margin shall exist between maximum power available and maximum power required when a load is lifted from the deck.

41
Q

VERTREP high power warning

A

Under high power conditions due to flight control mixing, pedal position is not necessarily indicative of tail rotor authority remaining. In particular, under high DA and aircraft gross weight conditions it is possible to achieve maximum tail rotor pitch without obvious indications from pedal position. This condition will manifest in one of two ways: no yaw response despite left pedal input or u commanded right yaw.

42
Q

ICS terminology

A 
Inbound for right seat pick/drop
Hook armed
Deck in sight
Load hooked up
Hookup man is clear
Weight is coming on
Load fouled
Load is clear
Clear to go
 Load riding well
Load unstable
Pickle pickle pickle
Load on deck
Hook clear
Pilot release hook
43
Q

ship maneuvering

A

Ships conducting vertrep shall not maneuver until notifying the pilots.
