Scenarios Flashcards
Should you ever put a swimmer on a hoist without a crew chief?
Hell no
No way to communicate, tell when to stop paying our cable, know when rescue is complete, etc.
SAR Immediate Action Items
Buster (means 106%)
- First turn towards SAR
Base (call back to ship)
Bingo (the 4 bingos)
Brief (Mission change / SAR)
Dipping Margin
Max of 111% or IRP, whichever is lower
5% power margin from AFCS limiter in actual hover allows for normal torque fluctuations with a normal sea state
Not dipping where base torque leaves me in 10 minutes range. Not enough time to actually do anything with the dome or have any time to troubleshoot
Cold Wx SAR Primary Risk
Death due to prolonged cold water exposure
In 50F water, 50% probability of death within 45 minutes (no exposure suits)
TLDR: get there as quick as possible, don’t go back to the boat for gear (30 min)
Ditching Script (Right seat)
I am flying, 2P, go through checklist steps and ensure everyone is locked up. AW, ensure egress hazards are clear (pax as required) and missile hazards are taken care of. Be a talking RADALT in the back.
We will turn into the wind and ditch on the backside of a swell if able. I want cabin open, windows will come out in the flare. I’ll pass you controls, pop my window, then take them back. Remember to reset your handles and put in your bottles.
2P’s hands on the PCLs, and pull them off when I say now. Once we’re wheels in the water I’ll apply the rotor brake. Remain in place with your hand on a reference point until the helicopter stops moving. Once we’re out, inflate your LPU and breathe out on the way up. We’ll meet up with me, upwind of any smoke or flames.
Fuel Ditching Distances
400# at the .5mi point, I will continue
- 20 min at 800pph = 266# (consider 340# unusable if light comes on at 600#)
- 30-50# for the approach
At any time below 600# I get an indication of fuel starvation (FUEL PRESS or sputtering) I will begin the ditch
How much does singling up save you?
At 4000’ saves ~1lb per mile. Takes 2-3 minutes to climb from sea level
How to single up
1) Find optimum altitude (~4K)
2) Climb dual engine
3) Perform Engine Shutdown in Flight
4) Get near descent point (~10mi)
5) Perform Engine Air Restart
6) Descend to land (1000fpm descent, 120kts, takes ~4min, at ~40%Q)
Night STAB Failure at OLF
Understand it’s not recommended
Risks: CFIT due to vertigo due to abnormal nose attitudes (P: low, S: High)
Mitigations: goggles, non-flying pilot outside, flying pilot instrument scan, obey stab speed limts
Benefits: aircraft is home, no additional maintenance flyers required
Decision: utilize other flyer if available, if not, take A/C home
SAS/BOOST Failure at OLF
Day: come home
Night: ?
Rules: Altitude hold overwater
Risks: CFIT due to vertigo from heavy control forces (P: M, S: H)
Mitigations: Swapping controls, instrument scan, goggles
Benefits: aircraft is home, no additional maintenance flyers
Blown Tire at OLF
Risks: FOD hazard, ground vibrations, unable to do running landing
Mitigations: visually inspect the wheel, prebrief ground vibe procedures, land to the line/pad 101, can’t mitigate running landing one
Benefits: aircraft is home, no additional maintenance flyers
EP Aircraft on Final, you also have an issue
Risks: depends on issue, but may be controllability or fuel
Mitigations: spur of the moment, minimal mitigations
Benefits: aid in the safety of the other crew, or of my crew
Night Single EGI Failure at OLF
Risks: dual EGI failure at night (disorientation/CFIT) (P: L, S: H)
Mitigations: goggles, standby instruments, fly airport to airport, call and talk to maintenance
Benefits: aircraft is home
Tail Rotor EP with Person on Hoist
If controllable, bring them up and depart. If can’t bring them up, lower, cut, and depart
