SOAL :

Rencanakanlah landasan pacu bandar udara dengan pesawat rencana yaitu

B-727-200.

Untuk pesawat terbang B-727- 200, panjang landasan pacu rencana dasar adalah 8600 ft = 2742,916 m untuk kondisi :

Operasional Pesawat terbang Normal

Untuk Operasional Lepas Landas

Take off distance

TOD = 1,15 x panjang landasan pacu rencana B-727-200

= 1,15 x 8600

= 9614 ft

= 3154,353 m

Take Off Run

TOR = panjang landasan pacu rencana

TOR = 8600 x 0.3281

TOR = 2742,916 m

Lift – Off Distance (LOD)

(LOD) = 0,55 x Take-off Distance

= 0,55 x 3662,934 m

= 1751,838 m

= 1751,838 x 3,281 ft

= 4949,729 ft

Untuk Operasional Pendaratan

Landing Distance (LD) = TOD

= 3154,353 m

= 9614 ft

Stop Distance (SD) = 0,6 x LD

= 0,6 x 3154,353 m

= 1892.612 m

= 1892.612 x 3,281 ft

= 6209.66 ft

Periksa :

LD =ଶଽ,,

LD = 10349.43 m ...ok!!!

Clearway (CW) = ( 0,5 .(TOD – LOD))

= (0,5 .( 3154,353 m – 1751,838 m))

= 765.1736 m

= 765.1736 x 3,281 ft

= 2510.535 ft

Stopway (SW) = 0,05 x LD

= 0,05 x 10349.43 m

= 517.4717 m

= 517.4717 x 3,281 ft

= 1697.825 ft

Panjang total dari jalur landasan pacu dengan perkerasan penuh (full strength hardening) yang dibutuhkan adalah :

Field Length (FL) = Take-off Run + (0,5 .(TOD –LOD))

= 2742,916 + (0,5 .( 3154,353 – 1751,838))

= 3508.09 m

= 3508.09 x 3,281 ft

= 11510.04 ft

Poor-approaches landing :

Landing Distance (LD) = TOD

= 3154,353 m

= 10349.43 ft

Stop Distance (SD) = 0,6 x LD

= 0,6 x 10349.43 m

= 1892.612 m

= 1892.612 x 3,281 ft

= 6209.66 ft

Clearway (CW) = 0,15 x LD

= 0,15 x 3154,353 m

= 473.153 m

= 473.153 x 3,281 ft

= 1552.415 t

Stopway (SW) = 0,05 x LD

= 0,05 x 10349.43 m

= 157.7177 m

= 157.7177 x 3,281 ft

= 517.4717 ft

Overshoot take-off :

Landing Distance (LD) = TOD

= 3154,353 m

= 13230,55 ft

Lift-off Distance (LOD) = 0,75 x Take-off Distance = 0,75 x 3154,353 m

= 2365.765 m

= 2365.765 x 3,281 ft

= 7762.075 ft

Clearway (CW) = 0,5 .(TOD – LOD)

= 0,5 .( 3154,353 m – 7762.075 m)

= 394.2942 m

= 394.2942 x 3,281 ft

= 1293.679 ft

Stopway (SW) = 0,05 x LD

= 0,05 x 3154,353 m

= 157.7177 m

= 157.7177 x 3,281 ft

=517.4717 ft

Pesawat terbang lepas landas dengan kondisi kegagalan mesin, sehingga harus melakukan emergency landing :

Landing Distance (LD) = TOD

= 3154,353 m

= 10349.43 ft

Stop Distance (SD) = 0,6 x LD

= 0,6 x 3154,353 m

= 1892.612 m

= 1892.612 x 3,281 ft

= 6209.66 ft

Clearway (CW) = 0,15 x LD

= 0,15 x 10349.43 m

= 1552.415 m

= 1552.415 x 3,281 ft

= 1552.415 ft

Stopway (SW) = 0,05 x LD

= 0,05 x 3154,353 m

= 157.7177 m

= 157.7177 x 3,281 ft

= 517.4717 ft

Untuk kondisi kegagalan mesin pada pesawat terbang, panjang jalur landasan pacu yang dibutuhkan adalah :

Field Length (FL) = Take-off Run + Stopway

= 2742.916 m + 157.7177 m

= 2900.634 m

= 2900.634 x 3,281 ft

= 9516.979 ft

Maka Accelerate-Stop Distance = Field Length

= 2900.634 m

= 12166,35 ft
