INFO Flashcards
Most recent INFO
New lavatory oxy sys
- bottle 3000 psi
- expires 25 yrs after production
- completed by Sept 2015
PWS
one pilot monitor WX the other TERR
if the WX radar is not on PWS scans for windshear 12 secs after thrust levers in TO range, so WX on will prevent the need for a high speed RTO.
ADS-B
transmits GPS position, speed, altitude, aircraft ID etc from FMS via the transponder
ADS-B OUT
uses transponder (limited range due to ground antenna) uses line of sight
ADS-C
uses VHF/SATCOM
ADS-B IN
displays information in cockpit, few airlines use this
ADS-B GPS and TX
if 1 GPS fails must select Tx on same side as functional GPS
ALT OFF - TX works and ADS-B transmits Extended Squitter.
Flt no. input transmitted on Extended Squitter
RNAV and RNP ops ANP
ANP - aircraft is 95% of the time within the RNP, when perf is not satisfied ‘UNABLE RNP’
XTK error
difference between LNAV and FMS position
does not consider ANP
deviation call at 1 * RNP track error
If XTK error > RNP no alert. UNABLE RNP only when ANP>RNP. Therefore, XTK error must be monitored by flt crew.
RNAV
onboard performance monitoring and alerting not required
decision of whether or not to continue is not dependent on display of UNABLE RNP and XTK error
verify/entering RNP value and XTK error monitoring required
conducted in radar coverage where controller monitors deviation from route
RNP
onboard performance monitoring and alerting required
decision of whether or not to continue is ependent on display of UNABLE RNP and XTK error
verify/entering RNP value and XTK error monitoring required
assumed outside radar coverage where pilots must monitor
RNP values
< FAF 1.0NM
>FAF 0.3NM
>MAP 1.0NM
RNAV 10 RNP 10
onbaord performance monitoring and alerting not required
RNAV (GNSS) app
FMS required to be updated by GPS but not onboard perf monitoring and alerting not reqd
GPS updating and RNP 0.3 reuired prior FAF by company (for convenience not having to monitor)
> initiating approach UNABLE RNP must discontinue app
RNP 4
no need to set RNP except for RNP 4 or RNP AR
don’t manually enter as it cannot then auto change
RNP airspace enter the RNP of 4, exiting RNP 4 DEL
