C-27J TAWS & TCAS

Question 1

TAWS active from:

Answer 1

30 feet after takeoff until landing

Question 2

TAWS warnings cannot be canceled, except:

Answer 2

GLIDE SLOPE and TOO LOW FLAPS (by pressing HUSH button on either control wheel)

Question 3

Once cancelled, will GLIDE SLOPE and TOO LOW FLAPS sound or appear again?

Answer 3

Only after the reset parameters are met (flying below 30 AGL or climbing through 1500 AGL)

Question 4

Two TAWS Mission Modes:

Answer 4

NORMAL and TACTICAL (inhibits warning envelopes to allow more aggressive flight ops)

Question 5

What triggers “BANK ANGLE” ?

Answer 5

Bank angle is greater than 61 degrees above 130 feet, reducing to 10 degrees at 30 feet or less

Question 6

What triggers “GLIDE SLOPE (soft voice)” ?

Answer 6

Deviation below glide slope greater than 1.3 dots

Question 7

What triggers “GLIDE SLOPE (loud voice)” ?

Answer 7

Deviation below glide slope greater than 2 dots

Question 8

What condition triggers “TOO LOW FLAPS” ?

Answer 8

Gear is down, radalt is 245 feet or less, and airspeed is less than 159 knots

Question 9

What condition triggers “ TOO LOW GEAR “ ?

Answer 9

Gear is UP, radalt is 400 feet or less, and airspeed is less than 150 knots

Question 10

What is the TCAS basis of operation?

Answer 10

TCAS identifies nearby aircraft with operating transponders. Mode 3A are processed for lateral data, Mode 3A & C provide lateral and vertical data. Warnings are based on predicted flight paths.

Question 11

What is the TCAS FORWARD airspace coverage?

40 nm (15 nm in high density area)

Question 12

What is the TCAS ABEAM coverage area?

Answer 12

15 nm

Question 13

What is the TCAS AFT coverage area?

Answer 13

12 nm

Question 14

What is the TCAS VERTICAL coverage range?

Answer 14

+/- 9000 feet

Question 15

What is the size of the TCAS “bubble” around the aircraft?

Answer 15

1200 feet

Question 16

How many seconds out is a Traffic Advisory?

Answer 16

20 - 48 seconds

Question 17

How many seconds out is a Resolution Advisory?

Answer 17

20 - 30 seconds

Question 18

How many targets will TCAS track?

Answer 18

Up to 45 targets

Question 19

How many targets will TCAS display?

Answer 19

Up to 30 targets to display, five on the PFD

Question 20

Will ground targets be displayed?

Answer 20

No. In general, if the target is within 400 feet of the ground it will not be displayed

Question 21

Under what conditions will ONLY Traffic Advisories be displayed? hint: there are four

Answer 21

1. Cargo door/ramp open
2. Paratroop door open
3. TAWS alerts
4. LPCR Windshear Alerts

Question 22

Which has higher priority: TAWS or TCAS ?

Answer 22

TAWS In case of simultaneous alarm, TCAS is placed in TA ONLY mode

Answer 24

Proximate Aircraft - White Filled Diamond is within 6 nm and 1200 feet

Question 25

Symbol "Yellow Filled Circle"

Answer 25

Traffic Advisory (TA) Yellow Filled Circle - Range/Closure rate warrants special attention. "TRAFFIC TRAFFIC" Aural Warning

Question 26

Symbol "Red Filled Square"

Answer 26

Resolution Advisory (RA) Red Filled Square - Position/closure rate requires corrective or preventative action. Visual & Aural Vertical Guidance (CLIMB CLIMB CLIMB) and visual maneuvering advisory on Vertical Speed Indicator.
