INS 10 - Warning and Recording Systems Flashcards
What are the three Alert Levels?
- Warnings, or Level A Alerts
- Require Immidiate Actions
- Cautions, Level B Alerts
- Require immediate Crew Alerness and possible further actions
- Advisories
- Crew Alertness Only
What are the colours associated with Alertting systems?
- Red is for Warnings
- Yellow or Amer for cautions
- White for advisories.
The Master Caution is a____1_____ and when pressed ends the ___2____ but the ___3____ reains on until the event is over?
- Switchlight
- Siren
- Light
Radio Altimeters are active below ______ in modern aircraft?
2500ft
A radio altimeter transmists in a 20/30/40 deg cone.
30deg
The radio aliter information is used for and the information is also sent too?
- Decision Height on a precission approach below 200ft
- Send the informaiton to GPWS and TCAS
The Radio altimeter is compensated for both ___1___ and ___2___.
- Gear Height
- Wiring in the aircraft
The frequencies transmitted by a continuous wave Radio Altimeter transmitts between?
4200Mz and 4400Mz
Radio Altimeters are accurate to?
+- 2ft in the first 500ft or 1.5ft which ever is greater
What are the Modes and warnings of GPWS?
- Mode 1 - Sink Rate
- Mode 2 - Ground Proximity
- Mode 3 - Altitude loss after take-off or go around
- Mode 4 - Incorrect landing configuration
- Mode 5 - Downward glideslop deviation
GPWS is required on what aircraft?
Jet or turboprop aircraft of more than 5700kg or more than 9passenger seats.
What is the difference between warnings and alerts?
- Alerts are less urgent and require a corrective response
- Warnings requires an immediate climb maneouvre
Pull up illuminates when which modes are activated?
Modes 1 to 4
If a gear up landing is being executed what can be used to prevent audiable warnings for flap and gear?
- FLAP INHIBIT
- GEAR INHIBIT
SYS TST when pressed will cause a?
BITEs
- Built
- In
- Test
- Equipment
If the BITE test is not as expected it has?
Failed
What is associated with MODE 1 GPWS?
- Excessive
- Active below
- Is caused by
- Broadcasts
- 1
- 2
- Excessive Barometric rate of descent
- Active below 2500ft
- Barometric rate of descent 3 times greater than radio height
- Broadcasts
- SINK RATE, SINK RATE
- WHOOP, WHOOP, PULL UP
What is associated with MODE 2 of the GPWS?
Caused by reducing radio altitude and ground rising from beneath
Broadcasts
- TERRAIN TERRAIN
- WHOOP WHOOP PULL UP. (If situation worsens)
This continues until radio altitude has stopped reducing and an increase of 300ft Baro altitude is registered.
What is associated with MODE 3 of the GPWS?
- Warns of barometric height loss after a take off or go around
- The flap selectors must be moved away from the land position
- Gear up must be selected
- The alert is “DON’T SINK, DON’T SINK”
- There is no warning.
What is associated with a MODE 4 of the GPWS?
- The proximity to the ground without appropriate gear and flap selections.
- At high speed to inform the pilot of ground proximity and will broadcast the alert “TOO LOW TERRAIN”
- At lower speeds if close to the ground the system will tell the pilot of the unusual situation with the alert:
- TOO LOW GEAR
- TOO LOW FLAPS
- Many authorities regard the high speed situation as a warning and immediate climb action is required.
If the BELOW G/S is pressed before an approach what happens?
The MODE 5 Alert will be inhibited and will reactivate on a go around.
TAWS shows terrain _____ below the aircraft.
2000ft
What are the three calssifications of warnings and alerts?
- Genuine
- Nuisance
- False
