HIFR Flashcards
HIFR should be initiated
With sufficient fuel remaining to bingo to a suitable landing site if unsuccessful
Wiggins/NI HIFR Rig
Ships hose - 100ft
HIFR assembly - 10 ft section with female CCR (closed circuit refueling) fittings (wiggins fittings) that connects to hose and male wiggins in helo
Manual emergency disconnect lanyard
NATO - compatible high capacity NHC HIFR rig
2 in lightweight hose Unisex couplings Automatic emergency breakaway Built in 45 psi pressure regulator and on/off control handle Emergency breakaway 450+/-50 lbs
What type of nozzle is required for a NATO ship
If a U.S. Helicopter performs HIFR with a NATO ship, it will be given. Parker nozzle. An adapter to convert the nozzle to a wiggins type connection will be required
Winds for HIFR
Relative winds 10-30 knots, 300-360, minimum pitch and roll
Wiggins/NI fitting can be installed backwards, so
ensure the emergency release t handle is located near the wiggins fitting that attaches to the aircraft fitting.
Aircraft would be forced to shear the hoist to effect an emergency breakaway
A low hover while wind is less than 10 knots may cause
Excessive salt spray which can decrease engine performance and reduce pilot field of view
When using the NHC assembly, the hose shall be
Secured to the deck to ensure proper functionality of breakaway system
Ensure HIFR fitting assembly is —– before connecting the hose to the refueling fitting
Grounded
The PIC shall ensure the _______ is completed prior to commencing approach, HIFR, transfer, etc
Landing checklist
Low fuel flow may be the result of
Low pressure from the ships pump
Aircraft altitude
Contamination in the HIFR filter canister
During HIFR, if the right cell fills faster than the left cell
Monitor fuel quantity gauges closely. If the difference in cell quantities persist, stop refueling before the right cell is full (approximately 1700 lbs) to prevent rupture of fuel cell
Flow of fuel when precheck valve is in precheck position indicates a shutoff system malfunction. If neither precheck switch will secure the fuel flow…
Fueling should be continued only if necessary
The HIFR fuses in the GO/no go canister should be capable of handling approximately _____ lbs. The actual capacity of the fuses depends on ________. The HIFR filter _____ be replaced after each flight involving in flight refueling.
10,000
The quality of fuel received
Should
The go no go canister is sensitive to both
Water and particulate matter
If either rig fails to disconnect when an emergency breakaway is attempted, it will be necessary for the aircrewman to
Quickly disengage the nozzle and grounding wire from the aircraft and cut the house cable
Night HIFR WARNING
Due to the hazards associated with night operations and the increased potential for a mishap, night HIFR operations shall not be son ducted except for reasons of operational necessity
Night HIFR Procedure Notes (NATOPS)
A chemlight should be connected to the hoist during night operations to provide visual reference to the hook position at all times
On final approach to the ship the lower anti collision light and search light landing lights should be off and the position light set to dim to prevent temporarily blinding or disorienting the flight deck crew LSE HCO
When operational necessity dictates the conduct of night HIFR, the following conditions shall exist
- A natural visible horizon as viewed by the pilot
- Ship motion should not exceed 5 pitch 10 roll
- Turn on HIFR heading lights and position LSE with both Amber wands at helicopter control point
- Establish radio contact with the helicopter and pass ships course and speed, pitch and roll, relative wind
Aircraft shall not be refueled if
Fuel is not clean and bright
Contains more than 2 mg/l of particulate matter
Contains more than 5 ppm of free water
I desire immediate HIFR
Fly by and return to hover on port beam give hand signal for desire HIFR and Fire flare seaward
HIFR Marking
Obstacle clearance is ensured when. The helicopter for the which facility is certified hovers oriented fore and aft with hoisting point over the H for hose pickup
Class 6
HIFR facility capable of delivering a minimum of 50 gallons of fuel per minute at a pressure of 20 psi to a height of 40 feet above the water
Class 6R
HIFR facility capable of delivering only 25-49 gallons of fuel per minute at a pressure of 20 psi to a height of 40 feet above the water
HIFR heading lights are required for
NIGHT HIFR operations. Red/yellow lights give pilot visual indication of the ships heading and provide a height reference during in flight refueling operations
HIFR green FDSSS meaning
Deck personnel properly trained. Fuel hoses properly recirculated and fuel samples taken at nozzle. Warn aircraft of changes of course
Night HIFR
Operations are extremely demanding and are only permitted for operational necessity
