A fast alignment should be complete in:
30 seconds.
When the IRSs are operating in the normal navigation mode they provide:
Attitude and true + magnetic heading.
Acceleration, vertical speed & ground speed.
Track, present position & wind data.
Which of the following is not a major component of the inertial system?
Instrument Display Unit (IDU) transfer switch.
During the preliminary cockpit preparation the pilot accidentally moves the IRS Mode Selector switch from OFF to ATT instead from OFF to NAV. How can normal IRS operation be regained?
Switch to OFF, wait for ALIGN lights to extinguish, then perform full alignment procedures.
The FMC contains 2 databases (Performance & Navigation database)
True.
With correct takeoff parameters, the FMC commands the selected takeoff thrust when the TO/GA switch is pushed. During the takeoff roll, the autothrottle commands the thrust & the FMC commands acceleration to between V2+15 & V2+25 knots.
True.
For LNAV to be engaged on the ground, the departure runway must be selected and the course, to the first waypoint, must be within ___ degrees of the runway heading.
5 degrees.
To climb to FL280 in the shortest distance, MAX ANGLE should be selected on this page:
CLB.
When penetrating turbulence:
The Turbulence N1 is a reference only. The autothrottle must be disconnected and the N1set manually.
The purpose of the FMC FIX INFO page is to:
Establish your position relative to any stored fix.
Create a new waypoint at the intersection of the active route and a radial or distance from a known fix.
If the FAULT light on the IRS Mode Selector Unit illuminates, it indicates:
A system fault affecting the respective IRS ATT and/or NAV Mode.
On the FMC TAKEOFF REF Page, the SEL temperature entry may be made in either degrees Celsius or Farenheit:
True.
The FMC Alerting Message ‘VERIFY POSITION’ indicates:
Position information is contradictory.
After completing the FMC CDU preflight actions, you look at the POS INIT page again. The SET IRS POS line is missing. What is required?
Nothing. This is a normal indication once both IRS’s have entered the NAV mode.
During PATH DESCENT and below the Speed Restriction Altitude, the FMC Alertting Message ‘OVERSPEED DICONNECT’ means:
VNAV has disengaged because airspeed has exceeded FMC Speed Restriction by more than 15 knots.
Using a Reduced Takeoff thrust setting may result in Automatic FMC of Reduced Climb Thrust.
True.
The purpose of the FMC LEGS page is to display the lateral and vertical flight path details for each waypoint and to make route modifications involving a portion of a route segment:
True.
The airplane is not certified for operations:
Above 82°N or below 82°S.
On which CDU is the ground speed displayed?
POS REF page 2.
Selection of an ILS approach from a DEP/ARR page will automatically remove a previously selected approach:
True.
With the CONTROL PANEL select switch on the DISPLAYS Source Panel in the BOTH ON 2 position:
The First Officer’s EFIS Control Panel is supplying identical inputs to the captain’s & First Officer’s displays.
Holding patterns appear as scaled representation if the airplane is within 3 minutes of the holding fix with the range scale set at 80 NM:
True.
If the FMC Alert Light of the LEFT / RIGHT FORWARD PANEL is illuminated. It means:
The FAIL light on CDU(s) is illuminated or an alerting message exists for both CDUs or test
switch is in position 1 or 2
Two GPS receivers receive GPS satellite positioning signals. The LEFT & RIGHT GPS receivers are independent and ech provides an accurate airplane geographical position to the FMC & other aircraft systems. GPS operation is automatic.
True.
