Electronic Flight Display

Question 1

ADC Air Data

Answer 1

provides typical Pitot-Static info
•Airspeed
•Altitude
•Vertical Speed

Question 2

Attitude Heading Reference System (AHRS)

Answer 2

Provides pitch, roll, yaw

Question 3

Attitude- heading reference system

Answer 3

• Gyros - angular velocities per each axis
• Newton’s 1st law : a body remains in motion unless the body is acted upon by an external force
• In this case, vibrating quartz tends to stay in vibrating plane
• Able to detect transition changes of roll, pitch & yaw
• Accelerometers - change of linear velocities per each axis
• Detects forces when roll and pitch are established
• Initial attitude reference (level)
• Inclinometer information

Question 4

Air Data/Attitude/Heading Reference System (ADAHRS)

Answer 4

• Air Data
• Uses digitized Ram & Static Air pressures with OAT
• Magnetometer
• Magnetic Heading information
• Three axis solid state gyro and accelerometer system
• Three Axis – Pitch, Bank, Roll
• Gyros - angular velocities per each axis
• Accelerometers – change of linear velocities per each axis

Question 5

Multifunction Displays (MFDs)

Answer 5

Provides in general
•Moving maps
•Checklists
•System status
•Flight plan information
•Nearest functions
Limitations
•In general you can only use the MFD as a reference (not primary)
•Refer to the aircrafts specific POH for more information
