TCAS procedures Flashcards
what des the there aircraft require in order to provide us with a TA/RA?
an operational transponder
what can the TCAS command which could be a risk?
manoeuvres that significantly reduce stall margins
what should we do if we get a stall warning during an RA manoeuvre?
abandon the RA and execute a stall recovery
what will happen if during an RA the intruders track or altitude information is lost?
the RA will terminate without a ‘clear of conflict’
what should be initiated if we receive a climb RA with the aircraft in the landing config?
G/A procedure
what does the TCAS do during a TAWS warning?
switches into TA mode with aural annunciations inhibited
how far away is an aircraft in the caution area?
20-48 seconds
how far away is an aircraft in the warning area?
15-35 seconds
what does a solid blue diamond mean on TCAS?
proximate traffic within 6nm and +/-600ft, not predicted to enter the collision area
what is a TA intended to provide?
SA and assistance in locating traffic visually
what are the PF’s actions on reviving a TA?
hands on controls and power levers, leave automatics engaged
what are the PM’s actions on receiving a TA?
turn on all external lights, seat belt sign
scan for visual contact
what is a typical altitude deviation experienced during an RA?
300-500ft
what may happen if we don’t immediately follow an RA?
additional RA’s where the aural and visual annunciations don’t agree with each other
what should the crew do when a ‘clear of conflict’ is received?
return to the previous ATC clearance
what annunciation will we get with a preventative advisory and what are our actions?
‘monitor vertical speed’
monitor the VS, keeping the VSI pointer out of the red area on the scale
what are the 4 corrective advisories?
‘climb climb’
‘climb, crossing climb’
‘descend descend’
‘descend, crossing descend’
what does a ‘crossing’ advisory mean?
our flight path will cross the intruders altitude during the manoeuvre
what is the purpose of a corrective, weakening or restrictive advisory?
to minimise or constrain the escape manouvres or resolve multiple conflicts in response to an RA
what are the 4 corrective, weakening/restrictive advisories?
‘adjust VS, adjust’
‘level off level off’
‘maintain VS’ maintain’
‘maintain VS, crossing maintain’
what are the PF’s actions in response to an RA?
- disconnect autopilot
- call for FD off
- prompt but smooth pitch into the green range adjusting power as required
what are PM’s actions in response to an RA?
- select FD off
- call ATC ‘callsign TCAS RA’
- monitor
what are the PM’s actions when clear of conflict?
‘callsign clear of conflict returning to (assigned level)’
action and confirm requests for FD modes and autopilot
