Takeoff congiguration
Each config is associated with a set of certified performance and therefore, always possible to determine a MTOW for each takeoff config –> optimum config is the one that provides the highest MTOW
Conf 1+F give better perf on long RW (better climb gradients)
Conf 3 give better perf on short RW (shorter takeoff distance)
Area Nav
Allow to navigate “point to point”, aircraft position being determined by on board nav system
IRS Nav
Allow to extend RNAV further than the range of nav aids
PBN
Concept specifies RNAV system performance requirement in terms of accuracy, integrity, functionality
RNP “X”
Based on required Nav performance when an on board monitoring and alerting system is implemented in addition to RNAV capability to warn the flight crew when the actual nav performance is insufficient
RNP X = RNAV X + onboard monitoring + alerting
GPS Primary
On board nav performance exceeds the currently known requirements for any kind of route
Windshear alerts inhibition
- At takeoff, alerts are inhibited above 100kt and up to 50ft
- During landing, alerts are inhibited below 50ft
GPWS
5 basic mode active up to radio height 2500ft
- Mode 1: Excessive rate of descent
- Mode 2: Excessive terrain closure rate
- Mode 3: Altitude loss after Takeoff or go around
- Mode 4: Terrain clearance not sufficient, if not in Landing config
- Mode 5: Excessive descent below glide slope
TCAS
Max range of 30 NM within altitude of 9900ft above and below
- Tcas calculates the intruder trajectory, closest point of approach (CPA) and the estimated time (TAU) before reaching CPA
- TAU is the ratio between the distance that separates both aircraft, and the sum of their speed
Weather radar
Has PWS when PWS in auto position, RA below 2300ft
- weather radar on
- weather radar off:
+ at least 1 ENG running
+ Ground speed greater than 30kt
+ Aircraft longitudinal acceleration above a given threshold during at least 0.5s
