FMS Flashcards
When is a Vertical Track Alert (VTA) issued while in VNAV?
VTA is issued 60 seconds before a climb or descent is commanded or 1000’ before level off
After leveling off at a waypoint altitude constraint during a VNAV climb will the climb continue automatically?
Yes, once the waypoint is sequenced the climb will continue
Does TCS maintain a new altitude when commanded?
If the altitude is change is less than 50’ no, but if the altitude change is greater than 50’ the new altitude will be held
How is TOD calculated?
Using the information input on the PERF INIT page
When is the DES NOW prompt displayed?
It is displayed on the FMS DESCENT, FLIGHT PLAN, AND ROUTE pages when less than 50nm from calculated TOD
When DES NOW is selected early what happens?
The FD commands a 1000 FPM descent up until the next altitude constraint, or the descent path is intercepted
What happens when a late DES NOW descent is selected?
The FD commands a 1.5° steeper than planned descent angle to intercept the planned path, unless the descent angle is not enough to intercept in which case a UNABLE PATH INTERCEPT message will be displayed
What is the normal takeoff speed schedule?
It does not provide guidance, but displays V2, until V2 is met, then it ramps up to V2 + 10kt until vertical mode is changed
What is departure speed guidance?
Speed command is selected on the DEP/APP speeds page and is defaulted to 200kt for 4nm below 2500’
What is climb speed guidance?
This speed is set on PERF INIT page 3/3, the default is 250kt below 10,000’ and once clear is the lower value of 280kt/0.73M
What is cruise speed guidance?
When at the planned cruise altitude the cruise speed is that which is set in PERF page
What is the speed guidance in descent?
Default is 290kt/0.76M/3.0°
What is Approach speed guidance?
Approach speed is selected on the DEP/APP speed pages. When flaps 1 is selected the FMS commands speed for the next flap
What is Go-Around speed guidance?
When G/A is selected the flight director sets speed defined in PERF INIT. If New approach is set while in go-around mode FMS reverts to approach speeds. If a new destination is set while in go-around mode FMS reverts to climb schedule
What are the 3 FMS databases?
Navigation, custom, and aircraft
What does GMS annunciation DR mean?
Dead reckoning mode, loss of navigation performance, loss of radio updating, and loss of position sensors for greater than 2 minutes
What does FMS annunciation DGRAD mean?
The FMS has lost RNP, GPS is not available and is required for the selected flight plan procedure
What does FMS annunciation APPR mean?
FMS is in approach mode operation. EDS sensitivity and FMS tracking gains are increased
What does FMS annunciation TERM mean?
FMS is in the terminal area and operating under increased navigation accuracy
What does FMS annunciation WPT mean?
FMA give WPT advisory 30 seconds prior to sequencing a waypoint
What does FMS annunciation VTA mean?
The FMS is warning of an impending vertical track command. These include: within 1000’ of capturing an altitude constraint, 1 min prior to TOD, 1 min prior to resuming a climb or descent from a constraint waypoint, prior to resuming a VFLCH descent due to speed limit altitude level off, 1 min prior to executing a step climb
What does FMS annunciation OFFSET mean?
It is an advisory that the FMS is flying an offset up to 30nm parallel
At what point prior to the approach must the APPR annunciation turn on?
2nm before the FAF and must remain lit for the duration of the approach. Only for FMS flown approaches
What 2 items must be checked when first getting to the PERF INIT page?
Aircraft type and tail number
What is the RSP Before start flow?
- Verify doors and windows closed

What is the trigger for the Before Start Checklist?
Called for be the LSP
What is the trigger for the After Start Checklist?
Ground staff and equipment clear of the aircraft
What is the RSP After Start flow?
- SLAT/FLAP set “Takeoff Flaps__Set”
- APU off if not required (wait 30 seconds after engine start)
What is the before takeoff checklist trigger?
Called for by the LSP
What is the RSP Before Takeoff Checklist flow?
- Takeoff signal (2 chimes)
- Brake Temperatures “ALL GREEN”
- EICAS/THRUST/FUEL

What is the 10,000’ in climb flow?
