80T-106 LHA/LHD NATOPS MANUAL Flashcards
In Service?
LHD-1 Wasp Class - USS Bonhomme Richard
LHA-6 America Class - Same flight deck as LHD-1 with reinforced flight deck for V-22 and F-35
LHA-1 Tarawa Class - No longer in service (reserve condition)
Weather Criteria
Case I - 1000-3 or better for helicopters
Case II - 500-1 or better for helicopters
Case III - Below 500-1 for helicopters or no visible horizon
Night helo EMCON mins - 500ft above normal delta pattern and 3nm visibility with well defined horizon
Airspace
Control Area - 50nm radius; upper limit as assigned (Approach = AATCC, Tactical Control = TACC)
Control Zone - 5nm radius; 2500ft (Tower)
Multi Ship Operations
When two or more aviation, mine countermeasures support or amphibious aviation ships are in close proximity, each should be assigned operating areas of sufficient size to preclude mutual interference
If overlapping control zones, OTC shall promulgate SPINS that delineate the limits of each ship’s airspace control, as well as the procedures to be used for VMC ops between contiguous control zones
Positive Control
Shall be utilized under the following conditions:
1. Ceiling of 500ft or less for helicopters
- Visibility of 1nm or less for helicopters
- Unaided flight ops 30 min after sunset until 30 min before sunrise, except as modified by the OTC or ship’s commander
* NOTE* Night CQ/DLQs are excluded from positive control provided there is a visible horizon - During mandatory letdown in thunderstorm areas
- Supervisory personnel can anticipate weather phenomena that might cause difficulty to pilots
Advisory Control
Shall be utilized when the traffic density in an operating area requires a higher degree of control for safety of flight than required under visual flight rules
Normally limited to VMC and is recommended for all operation in or adjacent to oceanic control areas or routes
Monitor Control
Shall be utilized only when aircraft are operating VMC outside controlled airspace and the responsibility for separation from other traffic can be safely assumed by the pilot
Non-radar Control
Shall be used when shipboard radar is inoperative or so degraded as to be inadequate to provide radar separation of air traffic under conditions normally requiring positive control
Condition I (Alert 5)
Aircraft shall be spotted for immediate launch, rotor blades spread, starting equipment plugged in
LSE, aircrew and ordnance personnel ready for luanch
Engines started when given “standby to launch”
Off deck within 5 min
Condition II (Alert 15)
Same as Condition I, except aircrews shall be on immediate call
Rotor blades may be folded or tied down; if folded, the blades shall be run through a unfold/fold cycle to ensure operability
Condition III (Alert 30)
Main rotor blades may be folded and the helo does not need to be spotted for immediate launch, however, it must have direct access to a suitable launch spot
A tow bar shall be attached to the helo and a specific LSE, tractor driver and handling crew shall be designated
Flight crews shall be in the ready room or working spaces in flight gear, pre-briefed
Condition IV (Alert 60)
Similar to Condition III, except that minor maintenance may be performed if no restoration delay is involved
Aircrew shall be designated and available
Launch Procedures
- Request permission from PriFly for APU start, engine starts, and engaging rotors via LSE; helos should not engage rotors in a turn, unless otherwise authorized by the ship’s CO or his representative
- Ready for launch pass souls and fuel state to PriFly, give LSE thumbs up
- Night launches: Pilot should not initiate any frequency or heading changes prior to 300ft
- Night launches: PriFly shall not require a frequency or heading change prior to 300ft unless required for safety reasons
Case I Departure
Used when IMC is not anticipated
Clear control zone at or below 300ft or as directed by PriFly
Case II Departure
Shall depart via Case I departures and maintain flight integrity below the clouds
If unable, execute Case III procedures
