LHA/LHD Definitions Flashcards
Advisory Control
A form of air traffic control in
which the controlling agency monitors radar and radio
contact with aircraft under its control and provides
traffic advisories. Traffic separation is the responsibility
of the individual pilot, with the assistance provided by
the control agency.
Air Capable Ship
All ships other than CV/CVN
or LHA/LHD from which aircraft can take off, be
recovered, or routinely receive and transfer logistic
support.
Amphibious Air Traffic Control Center (AATCC)
The centralized air traffic control agency
for LHA/LHD responsible for maintaining the status
and operational control of aircraft departing the ship
and recovery of inbound aircraft after a mission is
completed. AATCC is responsible for providing IMC
approach and departure control services. Also, AATCC
is responsible for maintaining the status and tactical
control of airborne helicopters in support of amphibious
assaults as directed by Tactical Air Control Center
(TACC) Helicopter Coordination Section (HCS).
Amphibious Assault Aviation Ship
An LHA or LHD
Angels
Altitude in thousands of feet
Approach Control
A control station in AATCC
responsible for controlling air traffic within the control
area except that controlled by final, departure, or marshal
control. It also is responsible for providing positive
control for all CCA waveoff traffic until a radar handoff
to another control station has been accomplished.
Bent
A term used to identify when a radar or NAVAIDis
down/out of service.
Ball
A pilot report indicating that the visual landing aid
is in sight.
Bingo

defined as being HERO unsafe when its external wiring
is physically exposed; when tests are being conducted on
the item that result in additional electrical connections
to the item; when EEDs/CADs having exposed wire
leads are present, handled, or loaded; when the item
is being assembled/disassembled; or when the item
is in a disassembled condition. Ordnance items that
fall into the above classification may be exempted
