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
The stall is a function of ______, rather than?
- Angle of Attack or Alpha
- Not Pitch Angle
When TOGA thrust is selected and stick hard back what will the aircraft do?
Clmb at max alpha conducting automatic terrain avoidance manoeuvre

If an aircraft is with in 35 to 48 seconds of entering the collision what is broadcast, and this is known as?
“TRAFFIC, TRAFFIC” Is broadcast
Its a Traffic Advisory TA
RA are Resolution Advisories and require?
