Water Flashcards
Splish Splash
What is the indication for engine performance loss?
February 3-3
Increase in TGT
When will TGTs be compared to the baseline you took before going feet wet?
February 3-3
During downwind of the pattern
What are the TGT increases we are looking for?
February 3-3
And what does each temperature increase indicate
TGT rise of 20 degrees or more is an indication of engine performance degradation (possible salt encrustation.
TGT rise of 40 degrees may result in compressor stall(s).
At what altitude AWL can we expect for salt buildup to increase?
February 3-3
Below 30’ AWL
What is the primary means for overwater flight?
February 3-3
The flight director
What is the CAUTION associated with the survivor using smoke to signal in maritime operations?
February 3-3
Do not use it when an oil or fuel spill is near the survivor.
What is the call if SMA is unable to scan anywhere else without losing visual with survivor?
February 3-3
PADLOCKED
NOTE: During the operational testing of the MOT function, how long did it take to execute the manuever (established in Hover Position Mode)?
February 3-3
3.5-4.5 minutes
NOTE: What is the drawback of using Continuous Mode (CONT)?
February 3-3
It will render radio communications on that frequency unusable.
What are the three primary approach methods?
February 3-3
- MOT to offset hover
- FD Alt/Airspeed hold to final, then Z-axis plunge direct to hover
- MOT to final, then Z-axis plunge direct to hover
NOTE: Where will the MOT function position the aircraft?
February 3-3
200’ AWL
100m downwind
100m left of the point where activated
NOTE: What determines the turn direction for the pattern after activating the MOT function?
February 3-3
By the FCCs based on wind conditions.
CAUTION: What has to be considered if you have to move the aircraft backward?
February 3-3
Climb to a safe altitude (above 30’) prior to backup up because it is possible to dip the tail into the water.
NOTE: What will expedite the team member and survivor entry into the cabin during a barrel-man recovery?
February 3-3
Setting the parking brake
What hover height is recommended for water ops?
February 3-3
70’ AWL
WARNING: Which device should not be pulled through the water by the hoist to get it into a postion for hoisting? Why?
February 3-3
The stokes, cable shock loading and survivor drowning may occur.
When using the stokes/rescue basket what course of action should the hoist operator follow if a spin develops?
February 3-3
Stop reeling cable in, establish a 15-20 knot forward troll using the FD
When should the SMA deploy the Rope Lader?
February 3-3
Once established in parameters, approximately 50’ short of the first team member.
What will the SMA call for/do after a RL, Fast Rope, or helocast?
February 3-3
Climb out of the sea spray (usually 70’) to pull in the ropes.
What is the predeployment consideration for a helocast to a survivor?
February 3-3
The aircraft’s flightpath should not pass directly over the survivor until the hoist pickup phase to reduce rotor wash over the survivor.
What are the helocast parameters?
February 3-3
10 KGS
10’ AWL
Maximums
What is the sequence of events for a helocast?
February 3-3
- Doors open
- Team disconnected once on final
- Aircraft in parameters (10 and 10)
- SMA calls “standing by swimmers”
- Pilot calls “Swimmers swimmer swimmers”
- SMA gives knife hand signal to swimmers while shouting
- “First swimmer out, second simmwer out etc.”
- Once team is deployed call “clear up to 70’”
- Verify a good thumbs up from each team member “3 thumbs up right side”
What is the minimum airspeed in the pattern?
February 3-3
50 KIAS
What is the max AOB in the pattern?
February 3-3
30 degrees
What is the Flight Manual warning associated with right vs left hand FD turns?
February 3-3
Right turns may cause airspeed to decelerate below 50 KIAS. This deceleration will disengage the FD and could place the aircraft in a near zero airspeed, high AOB, and high rate of descent.
What is the minimum pattern altitude until established on final?
February 3-3
100’ AWL
What will be accomplished on every downwind?
February 3-3
TFG
But what we really care about is the TGTs, checking for salt degredation
What does the Combat Rubber Raiding Craft weigh empty?
February 3-3
280 pounds
What is the sequence of events for a T-Duck CRRC procedure?
February 3-3
- At the 5 min call, the team extends the FRIES bar
- At the 1 min call the belayman is in place, slack removed from the belay rope
- Aircraft gets established in hover
- PF gives the “ropes” call
- Team pushes boat out of aircraft, belayman lowers it slowly into water
- One or more persons then deploy out the opposite door via fast rope and release the boat from the rope
- Remaining personnel deploy via fast rope
For maintenance debriefing, what salt spray conditions require entries in 781A?
AFMAN11-2HH60Wv3 Chapter 4
- “Engines subjected to salt spray at ____feet”
- If aircraft flown within 10 miles of saltwater or fligth below 3000’ AWL “Aircraft exposed to salt air at____ miles/____ feet”
- Hoist used in salt water (for lives/not for lives modifier)
