(For this question use annex 032-005 or Performance Manual SEP 1 Figure 2.4).
With regard to the landing chart for the single engine aeroplane determine the landing distance from a height of 50 ft. Given:
O.A.T.: ISA
Pressure Altitude: 1000 ft
Aeroplane Mass: 3500 lb
Tailwind component: 5 kt
Flaps: Landing position (down)
Runway: Tarred and Dry
Refer to figure.
(1) Enter the graph at the intersection of 1000 ft Pressure Altitude and ISA reference lines. Continue horizontally to the right until the the Mass "REFERENCE LINE".
(2) From this point, continue horizontally to the right until you intersect the reference line corresponding to 3500 lb (follow the mass reference lines).
(3) Now, continue horizontally to the the right to the Wind Reference Line. Apply the wind correction of 5 kt tailwind, by drawing a diagonal line up and to the right.
(4) Continue horizontally to the right until the next Reference line. Since the question is asking for the landing distance from a height of 50 ft - we must continue diagonally up and to the right following the reference lines. Read a result of approximately 1750 ft.
