ATR 72 - Navigation
Radio Altitude Indication on Altitude Scale is displayed when radio altitude is less than _____
The aircraft is equipped with two radio altimeter units.
The aircraft is equipped with one radio altimeter. The radio altimeter gives accurate height information when flying below 2 500 ft. The radio altimeter system includes one transceiver and two antennas.
The GPS 1 and GPS 2 provide the time information to other systems. GPS date and time can be displayed on clocks, and on MCDU.
The GPS 1 provides the time information to other systems. ONLY GPS 1 provides time information to clocks.
WXR Mode selector - On the ground, the system is automatically forced in STBY position for safety. If needed, it is possible to restore the active WX mode by pressing the STAB pb four times in 3 seconds.
When TERRAIN function is switched OFF (TERR OFF on ND), Excessive Bank Angle callout is only available:
When Excessive Bank Angle Callout is not available, GPWS fault is triggered.
TCAS Operating Characteristics – In icing conditions the RA INCREASED CLIMB is inhibited:
Priority must be granted to increasing airspeed when reaching Stall warning even when this requires deviation from an RA Command issued by the TCAS.
Refer to the FCOM Limitations chapter.
Radio altimeter - In order to set a decision height, Captain and First Officer have to set their respective ICP Outer/Inner knob to DH. Then the flight crew can set the required decision height value from:
The TCAS detection capability is limited to intruders flying within a maximum altitude boundary of _____ above and below own aircraft altitude.
Detection range depends mainly on intruder's XPDR type (mode A/C, mode S, ADS-B out) and external conditions.
TCAS – What does this RESOLUTION ADVISORY (RA) mean?

ND display after AHRS1+2 failure - HDG FAIL flag is display in case of dual AHRS failure. Heading indications on ND and HSI are lost.
To avoid giving nuisance alerts, the predictive TAWS functions must be inhibited when landing at an airport that is not included in the airport database.
Refer to the FCOM Limitations chapter.
The TCAS system is supplied by the:
All TCAS aural alerts are inhibited below _____ when aircraft is descending.
QFE operation is authorized with TAWS.
QFE operation is prohibited with TAWS! Refer to the FCOM Limitations chapter.
In normal operations, FMS 1 and 2 are synchronized and operate in dual operation even if both are achieving their own computation and exchange data through the cross talk link.
The weather radar system detects atmospheric disturbances and provides the flight crew with display of precipitation levels for ranges up to _____ in front of the aircraft.
It can also display terrain mapping information. Weather information can be displayed on the Captain and First Officer Navigation Displays (MFD pages) with RADAR background selected on Virtual Control Panel (VCP).
What does this TCAS information mean?
Solid diamond!
All TCAS aural alerts are inhibited below _____ when aircraft is climbing.
The Attitude Heading Reference System (AHRS) supplies the flight crew and the autopilot with the:

Pilots intending to conduct a LNAV procedure must be on the leg at least _____ before FAF (Final Approach Fix).
TCAS Display Configuration enables the flight crew to select the area in which the displayed intruders are located. With the 'BLW' selection the TCAS displays intruders from 9 900 ft below to _____ above the aircraft.
LPV Operation - Lateral CDI is a Magenta rectangle that is displayed with a lateral deviation scale when FMS navigation source is selected. Lateral CDI scale is composed of five fixed dashes that provide lateral deviation from FMS lateral path of the active FPLN leg. Half-scale equals current RNP considered by FMS with a maximum of _____.
WXR Mode selector - The RCT Pushbutton activates or deactivates the REACT mode which compensates the attenuation of the radar signal as it passes through rain fall. (WX RCT is displayed cyan on the MFD).
The cyan field indicates areas where further compensation is not possible. Any target detected in these areas will be displayed in magenta and should be considered as dangerous.
LPV Operation - Vertical CDI Magenta rectangle that is displayed with a vertical deviation scale when FMS deviation source is selected. Pointer and scale are displayed:
Aircraft is equipped with two independent Air Data Computers (ADCs). Each ADC computes:
Weather radar (Receiver Transmitter Antenna) is supplied by:
TCAS – What does this TRAFFIC ADVISORY (TA) mean?
Current Radio Altitude (RA) Numeric value is displayed from _____
