Warnings Flashcards
Learn various warnings
Altitude Alerting System
Visual and aural warning weekend approaching and deviating from target altitude. +/-900 & +/- 200
What is a common example of tactile alert?
Stick shaker
Mode 7
Reactive windshear alert
Flight data computer
300 parameters. 25 hours record time in digital format
Altitude alerter
900 ft when approaching, 200 ft when deviating from assigned altitude
Where can the EFIS be controlled if the efis control panel fails?
Via FMS or CDU (control and display unit)
When are the fire bell and master warning lights inhibited
On take off from rotate to 400 ft radio altitude
Doppler windshear
Weather radar and raindrop velocity
ECAM
Electronic centralized aircraft monitoring ( airbus)
On a boeing aircraft what color is EFIS “command”?
Magenta
GPWS high density red
Terrain greater than 2,000 ft above aircraft.
Gpws low density yellow
Terrain between 500 ft below and 1,000 ft above aircraft.
Total system error
Desired path to aircraft true position
ANP
Actual Navigation Performance
RNAV Approach
RNP 0.3NM
What is the secondary output of a inertial navigational system N-S accelerometer?
Distance.
How can digital data be accessed from the FDC?
Via printing EICAS or ECAM maintenance page or downloading ACARS
What is the product output of an inertial NAV SYSTEM NS accelerometer?
Velocity and local Meridian
Does FMS derived LNAV from DME suffer slant error
YES
What is the power supply for an IRS
Aircraft system and backup battery
What do ring laser gyros measure
Angular rates of rotation about a single axis
EICAS- WHAT COLOR IS STATUS
CYAN
SVS
Synthetic Visual System-terrain database that creates a 3D view of the outside world
Gain program
Increases the scale of the localizer display on ILS approach
Mode 1
Excessive descent rate.
Sink Rate produced when altitude gets below 2,500 ft AGL. SHOULD THE SINK RIGHT INCREASE, OR ALTITUDE DECREASES WARNING CHANGES TO ‘PULL UP’
Mode 2
Excessive terrain closure rate.
Initially Warns crew with ‘Terrain, terrain’
2 modes
2a- active during climb out, cruise and initial approac (no flaps)
2b, automatically selected when aircraft enters landing configuration
Mode 3
Altitude loss after takeoff or go around.
Initial warning ‘don’t sink’, which changes to
‘too low, terrain!’
Mode 4
Unsafe terrain clearance. 3 subsections
Mode 4a. Below approximately 500ft AGL. AIRSPEED around normal approach speed, and landing gear not deployed. ‘too low, gear’
If speed increases above landing speed, ‘too low, terrain’ will sound.
Mode 4a
Below approximately 500ft AGL. AIRSPEED around normal approach speed, and landing gear not deployed. ‘too low, gear’
If speed increases above landing speed, ‘too low, terrain’ will sound.
Mode 4b
Close to landing speed but no flaps in landing configuration. ‘too low, flap’ - changes to ‘too low terrain’ if speed increases.
Mode 4c
Intended to provide assistance, preventing inadvertent controlled flight into ground during TAKE OFF CLIMB.
Mode 5
Excessive deviation below glide slope.
Activates when airrafts under 1,000 ft AGL, undercarriage is down and a signal is being received by glide Path.
Warning ‘glide slope, glide slope’ sounds when deviation of more than 1.3 dots below path occurs.. volume increases if 2 or more.
Glide slope warning will be issued anytime between 300 ft and 50 ft RA and a glide slope deviation exceeding half scale deflection below
Mode 6
Excessive Bank angle, and altitude alerts.
Aural altitude callouts when the aircraft is descending. Determined by radar altimeter settings
Mode 7
Windshield alert. System has a wind speed envelope that categorizes up and down drafts with head and tailwinds
TCAS Traffic Advisory
TA region also known as ‘caution region’
Traffic advisory warning issued when intruder is approximately 30 to 45 seconds from ‘collision area’
Represented by SOLID YELLOW CIRCLE.
TCAS Resolution Advisory
RA issued when target within 25 seconds, and has relative altitude less than plus or minus 900 ft.
This is Visual and Audible, might also include directives such as climb climb, or ‘descend descend’.
RA displayed as solid red square.
TCAS DISPLAY
Non intruding traffic- altitude unknown. Open diamond in white or cyan.
Proximity traffic Solid White diamond or cyan.
Traffic Advisory. Solid amber circle
Resolution Advisory. Solid red square
Take off configuration warning system
Take off configuration warning system is armed when the aircraft is on the ground and when either throttles, or both are advanced for takeoff.
