ATA 34 Nav Flashcards
Where is air pressure sensed by the pitot probes sent?
2 Primary pitot probes connected to 2 primary Air Data Modules (ADMs)
ADM change pressure to electrical signal and send them to Air Data Inertial Reference Unit (ADIRU)
When is the alternate Maximum Operating Limit speed/Maximum Operating Mach (VMO/MMO) switch selected to the alternate position?
simulates a landing gear not down and locked condition by opening the ALL GEARS DOWN and LOCKED discrete.
How does the Integrated Standby Flight Display (ISFD) sense aircraft attitude?
Needs PITOT and STATIC system
Pitch and roll attitude come from the inertial sensors in the ISFD and an attitude ball in the center of the display
The Integrated Standby Flight Display (ISFD) shows ______ _______ to show barometric altitude.
static pressure
What is the frequency range for the ILS system?
108.10 to 111.95MHz <><><>
localizer antenna frequency?
108.10 to 111.95MHz
glideslope antenna frequency?
328.6 to 335.4MHz
Where is the marker beacon receiver located?
Bottom of the fuselage.
Where are the radio altimeter transceivers located?
E2 and E3 rack (E and E bay)
Which control panel is used to turn the weather radar ON or OFF?
Electronic Flight Instrument System (EFIS) control panel on the P-7 glare shield.
Which control panel is used to select the TCAS operating mode?
Air Traffic Control/Traffic Collision Avoidance System (ATC/TCAS) Control panel

How is the DME interrogator tuned?
Once you put a paired VOR or ILS frequency into the navigation control panel it goes to the DME interrogator and the DME then tunes a DME frequency in the range of 108.0-117.95MHz.
Where are the GPS antennas located?
On top of the aircraft
Where is GPS calculated position displayed?
FMC CDU displays the GPS Calculated position on the navigation data display
The FMS computer can provide __________ and ___________ navigation.
Performance, Guidance

What is the frequency range of the VOR antenna?
VOR antenna receives RF signals in the frequency range of 108.0-117.85MHz.
How often is the navigation data base in the FMC memory updated?
Every 28 days
