Accelerate Stop Distance (Figure 5-11)
SECTION 5
PERFORMANCE
(1 )
( 2)
Enter Figure 5-11 at 6500 pounds weight; engine failure speed
is 92 KIAS.
Proceed horizontally right from 30aO-foot pressure altitude to
the vertical
columns for 20
0
e. The distance required to accel-
erate to 92 KIAS and stop is 3990 feet without wind correction.
With a 19-knot headwind component, the accelerate stop distance
can be reduced by:
19 Knots Headwind (3%) = 11.4%
5 Knots Headwind
Corrected Accelerate· 3990 feet - [11.4% (3990 feet)]
Stop Distance
3990 feet [455 feet]
3535 feet
Accelerate Go Distance (Figure 5-12)
(1) Enter Figure 5-12 at 6500 pounds weight; engine failure speed is
92 KIAS.
(2) Proceed horizontally right from 3000 foot pressure altitude to
the vertical columns for 20
0
e. The distance required to clear a
50-foot obstacle,
after losing an engine at 92 KIAS, is 3370
feet without wind correction. With a 19-knot headwind compo-
nent, the distance can be reduced by:
19 Knots Headwind (2%)' 9.5%
4 Knots Headwind
corrected Accelerate = 3370 feet - [9.5% (3370 feet)]
Go Distance
• 3370 feet - [320 feet]
3050 feet
.----------NOTE-------.....,
.A more exact value of the distance required to accel-
erate go can be obtained using the interpolation
method .
• The interpolation method gives an accelerate go .
distance of 2716 feet without wind or 2458 feet with
19 knots of headwind.
Rate-Ol-Climb - Maximum Climb (Figure 5-13)
(1) Enter Figure 5-13 at 16'C (6I'F).
(2) Proceed vertically up to the 2400-foot pressure altitude line.
(3) Proceed horizontally right to the reference line. Follow the
slope
of the adjacent rate-of-climb lines until intersecting the
vertical
6200-pound line.
(4) Proceed horizontally right to obtain rate-of-climb. (1590 Feet
per minute)
(5) Enter the climb speed data to determine the climb speed cor-
rected for 6200 pounds and 2400 feet. (104 KIAS)
