Q

3 Factors to be considered while designing aircraft antennas:

A

The ENVIRONMENT to which Antenna is exposed.

The type of antenna used in each application will often depend on the SIZE OF THE AIRFRAME relative to the wavelength.

The most crucial consideration while deciding on the PLACEMENT of the antenna on the aircraft frame is the SAFETY OF FLIGHT.

Loop antennas also known as _______________.
DIRECTIONAL ANTENNAS
26
They are generally on the bottom.
LOOP ANTENNAS
27
Also known as highly directional.
MARKER BEACON ANTENNAS
28
It looks like little canoes about 10 inches long.
MARKER BEACON ANTENNAS
29
It needs to be on the bottom of the aircraft.
MARKER BEACON ANTENNAS
30
It is almost always mounted on the VERTICAL TAIL.
VHF NAV ANTENNAS
31
It has THREE TYPES: the cat whisker, the dual blade, and the towel bar. at a 45-DEGREE ANGLE
VHF NAV ANTENNAS
32
It looks like six-inch-square plates.
RADIO ALTIMETER
33
It placed on the bottom of the aircraft.
RADIO ALTIMETERS
34
Altimeter of an aircraft
RADIO ALTIMETERS
35
Those are commonly used for transponders and distance measuring equipment (DME).
UHF ANTENNAS
36
They are ALWAYS found on the BOTTOM of the aircraft.
UHF ANTENNAS
37
They are about four inches long.
UHF ANTENNAS
38
Transmitters and receivers must be connected to their antenna(s) via __________________.
CONDUCTIVE WIRE
39
It is a digital communication system used on aircraft that allows messages to be sent and received in text format between aircraft and ground stations. (PILOT to CONTROL TOWER)
ACARS (Aircraft Communications, Addressing and Reporting System)
40
ACARS messages are received on the aircraft by one of 3 METHODS:
VHF (VERY HIGH FREQUENCY) HF (HIGH FREQUENCY) SATCOM (SATELLITE COMMUNICATION)
41
This is for short-range communication limited by line of sight. Also referred to VHF Data Link (VDL).
VHF (VERY HIGH FREQUENCY)
42
It functions at a long range including over the ocean and in polar region.
HF DATA LINK
43
Those are available in most places on the planet except in polar regions.
SATCOM LINKS
44
3 Types of ACARS Messages:
ATC (AIR TRAFFIC CONTROL) AOC (AERONAUTICAL OPERATIONAL CONTROL) AAC (AIRLINE ADMINISTRATIVE CONTOL)
45
The most common use of ACARS with _______ is for CLEARANCES.
ATC (AIR TRAFFIC CONTROL)
46
It is used regularly during a typical flight by the pilots to receive the LOAD SHEET prior to departure.
AOC (AERONAUTICAL OPERATIONAL CONTROL)
47
It is to provide relevant admin information such as the PIL (Passenger Information List) which contains INFORMATION such as PASSENGER connections, available seats, etc.
AAC (AIRLINE ADMINISTRATIVE CONTROL)
48
It means they want you TO CONFIRM that you understood their latest instruction.
ACKNOWLEDGE
49
means…YES.
AFFIRMATIVE
50
They are used to describe when a radio transmission was NOT READABLE due to multiple radio transmissions on the same frequency.
BLOCKED or STEPPED ON
51
Quite simply…HURRY UP.
EXPEDITE
52
This is a question that a pilot or controller can ask another pilot or controller about the quality of their radio transmission.
HOW DO YOU HEAR ME?
53
It means switching to the frequency and listening to wait for further instructions.
MONITOR
54
The official way to say…NO.
NEGATIVE
55
Opposite of affirmative.
NEGATIVE
56
It’s simply an acknowledgment of hearing and understanding.
ROGER
57
It means I have received and understand your radio transmission.
ROGER
58
A request TO REPEAT the previous radio transmission, most likely due to a misunderstanding in communications.
SAY AGAIN
59
ATC cannot grant a request from a pilot.
UNABLE
60
It means you have heard the request and will comply with the instructions. "WILL COMPLY"
WILCO
61
The pilot cannot comply with a request from ATC.
UNABLE
