MHSET Studying Flashcards
Define: Land as soon as Practicable
means that extended flight is not recommended, the landing site and flight duration are at the discretion of the aircraft captain
Define: Land as soon as possible
means that continued flight is not recommended; land at the first site at which a safe landing can be made.
Define: Land immediately
means that an immediate landing/ditching is mandatory. The consequences of continued flight are more hazardous than those of landing at a site normally considered unsuitable.
Define: Warning
Warnings are used to emphasize an operating or maintenance procedure, practice, condition, statement, etc., which, if not strictly observed, could result in injury to or death of personnel.
Define: Caution
Cautions are used to emphasize an operating or maintenance procedure, practice, condition, statement, etc., which, if not strictly observed, could result in damage to or destruction of equipment, loss of mission effectiveness or long-term health hazards to personnel.
Define: Note
Notes are used to point out a procedure, event or practice which is desired or essential to highlight.

(AOI 3-3-1 para 6 & 7, SHOPS 5-1-3 Art 5110)
When do the fuel filter bypass lights illuminate?
The fuel filter bypass caution lights will illuminate whenever the fuel filters of the respective tanks are becoming clogged. This indication will occur prior to the point at which differential fuel pressure will unseat a relief valve within the filter, resulting in unfiltered fuel bypassing the filter and being delivered to the engine.
(AOI 1-3-6, para 21)
What will cause the main, interim, or tail chip lights to illuminate?
The CHIP DET MAIN warning light illuminates when a main gear-box magnetic chip detector has picked up and retained metallic particles or chips in the oil.
The CHIP DET INTERM and CHIP DET TAIL warning lights will illuminate if a chip is detected in the respective gear-box or if the temperature in the gear box exceeds 140 ± 6 degrees Celsius
(AOI 1-4-8, para 26)

The essential bus supplies power for operation of the DC flight instruments and all equipment necessary for safety of flight
(AOI 1-5-9, para 31-33)
What does the Primary bus power? ?
The primary bus supplies power to equipment necessary for completion of missions
(AOI 1-5-9, para 31-33)
What does the Monitored bus power?
The monitored bus supplies power to equipment not required for safety of flight
(AOI 1-5-9, para 31-33)
What pressure does the utility hydraulics system operate at? What about the hoist?
The utility hydraulic pump, located on the accessory drive section of the main gear-box, provides 3000 PSI hydraulic pressure. The hoist winch motor is powered by 1250 PSI hydraulic pressure from the utility hydraulic system.

Define Close Control.
A form of aircraft mission control in which the aircraft is continuously controlled for altitude, speed and heading to a position from which the mission can be accomplished.
Define Loose Control
A form of aircraft mission control in which the aircraft commander selects his/her own speed, altitude, heading and appropriate tactics to accomplish the assigned task. The controlling unit (host ship) will advise the aircraft of the current tactical picture and will provide further advice if and when available.
Define Broadcast Control
In the absence of full capability, or if the tactical situation precludes close or loose control, aircraft may be operated under broadcast control. Tactical or target information is passed to enable the aircraft to accomplish its task. The controlling unit, when possible, provides adequate warnings of hazards but the Aircraft Commander is responsible for aircraft navigation and collision avoidance.
Define Positive Control
The controlling unit is responsible for taking actions for collision avoidance such as ordering necessary alterations to heading, speed and altitude to maintain separation criteria.
Define Advisory Control
The controlling unit will provide adequate warnings of hazards affecting aircraft safety. The Aircraft Commander is responsible for the aircraft’s navigation and collision avoidance.
The TACCO is responsible to the Pilot for the following:
Safe navigation of the aircraft
Performance of assigned aircrew duties
The TACCO is responsible to the MHCC for the following:

Coordinating and directing operations
The AES Op shall be responsible to the pilot for:
Performing aircrew duties as may be assigned and to the MHCC for:
The operation of sensors as directed by the TACCO; and
The interpretation of sensor information
(FOM Appendix 2.2.1.1.C.2 para 5-9)
