Flashcards in Flight Warnings Deck (13):
1

3 types of warnings

Visual
Auditory
Physical

2

Level A warnings

Warnings

Req immediate flight crew action

Red captions

3

Level B warnings

Caution

Req immediate flight crew alertness in preparation for possible future actions

Amber captions

4

Level C warnings

Advisory

Req flight crew alertness (amber captions with indent)

5

Boeing and airbus alt alerts

Alerts if you deviate above or below the selected alt

Amber box around it

Boeing = +/- 300 ft to +/- 900ft

Airbus = +/- 250ft to +/- 750ft

6

Stall warning module takes inputs from

ADD(AoA vane)
Flap and slat position
ADC/ADIRS
Thrust levers
Air ground logic switch - tells the a/c you are on around

7

TCAS 1 proximate traffic

Solid white or cyan diamond

Within 6nm horizontally and +/- 1200ft vertically or within 6nm and no alt data

8

TCAS 1 other traffic

Hollow white or cyan diamond

More than 6nm or more than +/- 1200ft

9

TCAS 1

Only performs traffic advisory

Displayed as a amber/ solid circle when a/c are close by

Provides aural warnings but no escape manoeuvre commands e.g “traffic, traffic”

Crew must visually locate the traffic

Traffic advisory within 28 to 48 secs

10

TCAS 2

Performs like a TCAS 1 but can command escape manoeuvres

Within 15 to 35 secs of CPA

In order to be visible - must carry mode A, C or S transponder - min C

Discrete data link between the 2 a/c deciphers the best course of action

11

Resolution advisories

Must be followed

Gives escape commands in the vertical plane

Shown as a red solid square

12

When is the arrow shown on the a/c

When the vs of the traffic is greater than 500fpm

13

A/c equipment - TCAS

TCAS computer
2 directional antenna - 1 on top, 1 below
Mode s transponder
Receives data inputs from - radio alt, inhibits RAs close to the ground and the ADC
