Landing Performance
The Landing Phase is initiated when:
Aircraft is not on ground
and
Rate of climb ≤ –200ft/min
and
Radio altitude ≤ 100 ft
and
Calibrated airspeed ≥ 1.5 x (stall speed of current configuration)
The Landing Phase ends when:
Takeoff Reset is selected
or
In-air Reposition is selected
or
Aircraft On Jacks is selected
50 Ft AGL (Type
1)
When radio altitude ≤ 50 ft
T/D Point (Type 1) When any strut has load on it. This is the origin for the time and
distance calculations for 50 FT AGL and VSTOP.
VStop (Type 1)
When aircraft is on ground and ground speed ≤ 10 kts
5.8.7
Go-around (GA) Phase
The GA Phase is initiated when:
Aircraft is in Landing Phase
and
Either TLA ≥ 50°
and
Rate of climb is positive
and
Radio altitude < 2000 ft
App Climb Grad
(Type 2)
Updated in real time with the average gradient to the current point
from where a GA Phase has been detected and the gear is up.
This is continually updated to the point where the GA Phase is no
longer valid. This last calculated gradient is effectively the average
over the whole of the segment. This value is held until initiation of
another landing is detected.
Ldg Climb Grad
(Type 2)
Updated in real time with the average gradient to the current point
from where a GA Phase has been detected and the gear is down.
This is continually updated to the point where the GA Phase is no
longer valid. This last calculated gradient is effectively the average
over the whole of the segment. This value is held until initiation of
another landing is detected.
