General Aviation/Honeywell Terms Flashcards
Magnetometer
A magnetometer is a passive instrument that measures changes in the Earth’s magnetic field
-senses magnetic field
What is direction of the pitch axis on the plane?
lateral (going sideways, left and right wings)
What is direction of the roll axis of the plane?
longitudinal axis- front and back of the plane (nose to tail)
What is direction of the yaw axis on the plane?
vertical (up and down)
what are attitudes referred to?
rates
what is the schuler cycle?
error introduced by the moving the box when its not expecting to move. The error will continue
what is the abbreviation of flight control system
FCS
What is an FPGA?
Field Programmable Gate Arrays
Matrixes of little logic gates. Program shows how the logic gates need to be connected to make various logic circuits
What is Tim’s analogy of a FPGA
Kind of the brainstem (breathing, seeing). Every 400hz you got to get gyro data
What does Plock mean?
Phase Lock
AEL
Associated equipment list
SDI
Source Destination Indicator
Do the AH1000 and Micros have different SDIs?
AH1000 will have a different number… micro will have a different number
NCD
No Computed Data
How is the Transmit schedule based?
Based on frequency
Normal Mode
the unit can produce magnetic heading info
Basic mode
the unit can produce magnetic heading information but its not accurate
I2C
Integrated circuit
Pulse width modulated signal
-The width of the pulse determines how much acceleration its experience
-More acceleration means higher pulse..wider pulse
-Less acceleration means narrow pulse… lower pulse
EEPROM
Electrically erasable programmable Read-Only Memory
-Memory that is written in to it. if it power down and power up.. it wont lose the data
-Configurations files are stored in this file
o Written at integration test
o If the eeprom is faulty, all the other tests will fail
CRC
Cyclic redundancy check
Why can CRC replace checksums?
Problem with checksums, if there are two colums with a problem (incorrect sum)
- Cant detect multiply bit errors
- CRC replace checksums
o Internet has CRCs in it
Uses another algorithm
Compensation Engine
Doing the math for the data
How does a CRC find a primary number in binary form?
Division is done on a data set into the binary number. A unique value is calculated
HASS
Highly Accelerated Stress Screening
ATA
Air Transport Association
What did Tim say about what ATA does?
What did Tim say about flying an aircraft with the purpose of making money?
- Has requirements from the FAA
- Different requirements than a private
- Getting money for gasoline is revenue based on
How many versions of the 787 are there?
There are 3 (-7,-9,-10)
How is an FPGA used in image/video processing?
FPGAs are used in cameras and smartphones to accelerate features like image stabilization, facial recognition, and high-definition video encoding/decoding
What everyday items are FPGA is used?
FPGAs are used in a variety of everyday items including smartphones, high-end cameras, modern cars, network routers, medical imaging devices, and some high-performance gaming console.
Where are FPGAs used?
essentially anywhere where high-speed data processing or real-time control is needed, often for tasks like image/video processing, signal processing, and communication protocols.
How are FPGAs used in cars?
Field Programmable Gate Arrays (FPGAs) are used in cars to enable a variety of features, including Lane departure warnings, Adaptive cruise control, Automatic emergency braking, Display interfacing, Local dimming, Fuel management, Ignition control, Transmission control,
How is an eeprom used in cars?
In vehicles, EEPROMs are used to store important data such as mileage, VIN number, and calibration data for various systems.
How does an iPhone use a magnetometer?
A phone uses a magnetometer to measure the Earth’s magnetic field, which allows it to determine which way is north and thus power compass functionality within apps like Google Maps or a dedicated compass app; essentially, by detecting the strength and direction of the magnetic field around the phone, it can calculate its orientation relative to magnetic north
What are everyday tasks or items I2C is used?
Audio devices like digital speakers and sound systems use I²C to adjust settings.
Devices like thermostats, smart home sensors, and fitness trackers use I²C to read data from temperature, humidity, and motion sensors.
How is CRC used in downloading files?
Downloading Files – When downloading files from the internet, CRC helps verify that the file wasn’t corrupted during transmission.
How is CRC used in sending emails and messages?
CRC ensures that emails and instant messages are transmitted correctly without errors.
How is CRC used in making mobile calls?
Making Mobile Calls – CRC helps detect and correct errors in digital voice signals for clearer phone calls.
How is CRC used in streaming?
Watching Streaming Videos – CRC checks data packets to prevent glitches in streaming services like Netflix and YouTube.
what are everyday tasks a pulse modulated signal is used?
Controlling Fan Speed – Computer cooling fans, car HVAC systems, and ceiling fans use PWM for speed control.
Operating Servo Motors in Appliances – Microwaves, washing machines, and robotic vacuums use PWM to control motors.
Charging and Power Regulation – Phone chargers and power supplies use PWM for efficient energy conversion.
How many airplanes are in the air right now?
Aviation analysts estimate that there are about 16,000 airplanes worldwide in the air at any given time of day.
What is AFDX? What subassembly was the AFDX removed?
Avionics Full-Duplex Switched Ethernet (AFDX), also ARINC 664, is a data network, patented by international aircraft manufacturer Airbus, for safety-critical applications that utilizes dedicated bandwidth while providing deterministic quality of service (QoS).
