Q

UHF (ultra-high-frequency) radio waves

A

These frequencies are advantageous because they have high penetrating power and can easily pass through buildings. Disadvantages are that they only travel a short distance and are limited to line of sight. These frequencies are more applicable in urban areas.

Q

Repeater

A

A device that receives transmissions from a low-wattage radio and rebroadcasts the signal at a higher wattage and perhaps a different frequency. This increases the range of mobile transmissions, especially over rough terrain.

Q

Trunked

A

A system that pools several frequencies and uses a computer to route incoming transmissions to the next available frequency. This frees the dispatcher or field unit from having to search for an available frequency.

Q

What is the function of an encoder in a communications system?

A

A combination lock on a radio. By transmitting a series of tones, a transmitting station can unlock the receiver at a particular radio so it can receive traffic intended for it. Allows base stations to share a frequency without having to listen to traffic not intended for them.

25
List three alternative technologies that can be used to supplement radio communications.
Cellular telephone. Facsimile. Computer.

27
Human error types
skill deficiency- perception errors- decision making errors
28
Helicopter shopping
the practice of making sequential calls to numerous air medical providers in an attempt to find a service that will accept a call that other services have declined
29
Part 135: Basic VFR Weather Minimums
1200' ceiling (or above) and 3 miles visibility
30

flip upside down
31
water ditching
intentional landing into a body of water
32
Disadvantages of fixed wing transport
Cost between $10,000 for short flights to $100,000 for Intercontinental- must maintain landing fields runway length restrictions, hangers required
33
Part 91: Basic VFR Weather Minimums
1000' ceiling or above
34
VHF (very-high-frequency) radio waves
Low-band radio waves are able to curve and follow the shape of the earth or move around obstacles. This enables commnication over long distances. They are susceptible to interference. High-band radio waves travel in a straight line and do not bend to follow the curve of the earth or around obstacles. They are less susceptible to interference.
35
Incline Rule
Always approach an aircraft from the downhill side
36
Part 135: Basic IFR Weather Minimums (DAY)
500' ceiling (or above)

38
Rule of 3s
3 minutes without oxygen, 3 hours without shelter, 3 days without water, 3 weeks without food
39
Disadvantages of rotor wing
More restricted weather regulation than fixed wing transport, smaller interior space, more expensive to own and operate, weight limitations
40
Define: CAMTS
A program dedicated to ensuring high quality patient care and safety with ground, fixed- wing, and rotor- wing services.
41
Attributes of rotor wing
Vertical takeoff and landing, speeds about 150 mph, able to operate at altitudes below 2000 feet, able to move from point to point
42
Average cost per flight (helicopter).
$5-10K
43
4g
the amount of force required to initiate the ELT
44
Three basic governing concepts of air medical services
Bring critical care personnel to the patient, stabilize the patient, transport to a tertiary center
45
Simplex
A communication system that uses radios that transmit and receive on the same frequency. This means that only one radio in the system can transmit at a time.
46
What federal agency regulates the use of radio communication in the United States?
The Federal Communications Commission (FCC)
47
Hot Loading
refers to loading a patient onto or out of the aircraft while the engine is running
48

50
Flight following requirements: ground transportation
Every 45 minutes
51
How are the basic modes of EMS communication used during a typical EMS call?
Between the the party requesting for help and the dispatcher. Between the dispatcher and the paramedic. Between the paramedic, patient, receiving facility, and/or medical direction physician.
52
CFR Part 91
Code of Federal Regulations- regs for the domestic flights
53
Safety Briefings
daily discussions including the daily plan, crew member duties, equipment and aircraft issues, weather expectations, and emergency situations
54
Base station
The principal transmitter and receiver of a communications system.
55
Human error
This is the leading cause of crashes in flight medicine
56
Flight following requirements: fixed wing

57
Two major types of fixed wing aircrafts
Turboprop, jet engine
58
An incident where a pilot does not have to maintain flight following with ATC in IFR conditions
When the pilot checks in with the EMS communication center every 15 minutes
59
Attributes of fixed wing transport
Safer due to established landing zones, speeds between 250 to 600 mph, travel greater distances, care he multiple patients
60
Multiplex
A system that has the capability of transmitting two signals, usually voice and ECG, on the same frequency. This allows a paramedic to transmit ECG telemetry to a hospital while continuing to talk with the on-line medical control physician.
61
Three types of rotor wing mission profiles
Transport of sick and injured, search and rescue, police operations
62
55%
percentage of crashes that occur during scene flights
63
The two types of flight rules
Visual flight rules (VFR) and instrument flight rules (IFR)
64
Somatogravic illusion
Rapid acceleration that produces illusion of nose-high altitude and prompts you to enter a dive
65
CFR Part 135
Code of Federal Regulations- regs for the domestic commuter flights
66
Advantages of twin engined helicopters
Two patient capacity, larger openings, larger patient care area, greater lift capacity, duel engines in case one fails
67
Define: pilot isolation
This occurs with the pilot isolates himself from internal aircraft communication so that they can relay information to air-traffic control
68
Weather Decline
the act of not accepting a flight based on poor initial or future weather conditions
69
100 x 100 feet
common size of a HEMS landing zone
70
40%
percentage of crashes that occur at night
71
Crew resource management
the practice of using all available information, people, and equipment to achieve safe and efficient flight operations
72
Duplex
A communication system that uses radios that transmit and recieve on different frequencies. The paired receive and transmit frequencies in a system that are referred to as a channel. Radios can transmit and receive simultaneously, allowing communications to take place as if they were going over a telephone line.
73
Minimum effective distance that HEMS becomes quicker than ground transport.
34 miles (30 nautical miles)
74
What are prearrival instructions?
Directions for appropriate initial emergency care read to a caller by a trained dispatcher while EMS personnel are responding.
75
PSAP (public safety answering point)
The single location where 9-1-1 calls from a specific geographic area are routed for answering.
76
Emergency locator transmitter
hardware on board to begin transmitting a radiobeacon once an aircraft crashes
77
6 o'clock position
dangerous location of the aircraft because of the spinning tail rotor
78
Flight following requirements: VFR helicopter
Radio contact every 15 minutes
79
Advantages to single-engine helicopters
Start up time 3 to 5 minutes, less downtime for maintenance, lower costs, lower fuel requirements, smaller landing zones

81
Define: Undertriage
