Flashcards in All Deck (143)
What emergency equipment is located in the cockpit?
4 o2 masks/smoke goggles
4 life jackets
4 fire: crash axe, halon fire extinguisher, PBE, gloves
2 escape ropes
2 flash lights
When you turn the mode selectors to NAV, what are you looking for on the panel?
Ensure that each ADIRU has the ability to revert to the batteries by observing the BAT light illuminating for several seconds.
What does the ON BAT light indicate?
It is illuminated amber if one or more IR(s) is supplied by the aircraft battery. Also illuminates briefly during the beginning of a full alignment.
How long will each ADIRU stay on battery power?
ADIRS 2 and 3 will remain on battery power for 5 minutes to hold alignment until a generator can be restored. ADIRU 1(ADIRU 3 if captain selected ATT HDG CAPT 3) will remain on battery power until generator power is restored or the batteries fail.
What information is provided by the IR units (FAT HAAG)?
Flight path vector
What information is provided by the ADR units (BOATS)?
What does a steady white ALIGN light indicate?
The respective IR is in the Align mode.
What does a flashing white align light mean?
-No present position entered within 10 minutes of NAV selection (no position)
-difference of 1* lat/long between shutdown and entered position (wrong position)
-IR alignment fault (aircraft moved)
What does it mean when the IR lights are extinguished?
Alignment has been completed
What does steady illumination of the amber IR FAULT light indicate?
A fault affects the respective IR
What does flashing illumination of the amber IR FAULT light indicate?
Attitude and Heading may be recovered in ATT mode (you have lost the navigation portion)
What does the Amber ADR FAULT light indicate?
A fault is detected in the Air Data Reference portion
Does turning the IR to OFF also turn off the ADR?
Can you turn the ADR OFF and still have the IR?
What would be missing from the captains PFD if IR 1 failed or was turned off?
Attitude and navigation information
What action would recover the attitude and navigation information?
Selecting CAPT 3 on the EIS switching panel ATT/HDG selector
What information must be input when the IR is in ATT.
Input Heading on IR panel every 10 minutes
With the loss of ADR1, what would be lost in the captains PFD?
Airspeed and Altitude information
What would restore the lost altitude and airspeed information?
Selecting CAPT 3 on the EIS Switching Panel Air Data Selector
How do you normally enter Present Position into the IR?
-insert the Lat/Long on the MCDU INIT page
-then press Align IRS
Describe a post flight ADIRU accuracy check
-select Position Monitor Page. Verify position deviation is < 5 nm for each ADIRU
-verify residual ground speed in each ND (ATT HDG CAPT 3 for IR 3) is < 15 knots.
What does ELAC stand for?
Elevator Aileron Computer
How many ELAC's are installed?
What are the functions if the ELAC?
-normal elevator and stabilizer control
-normal aileron control
-normal pitch and roll
-direct pitch and roll
-acquisition of autopilot orders
Under normal law, what does ELAC 2 control?
- primary: elevator/stabilizer (pitch)
- standby: aileron control (backs up ELAC 1)
What backs up ELAC 2?
What does SEC stand for?
Spoiler Elevator Computer
How many SEC's are installed?
What functions are performed by the SEC's?
-normal roll (by controlling the spoilers)
-speed brakes and ground spoilers (SEC 1 & 3 only)
-alternate pitch (SEC 1 & 2 only)
-direct pitch (SEC 1 & 2)
