Example Landing Problem – Pre-Departure (>)
The following example illustrates the manual (ACCULOAD unavailable)
method to obtain the maximum allowable dispatch landing weight at a particular
airport for the forecast landing conditions, ambient temperature, wind, terrain,
etc.
Note: Examples for the non-normal operations such as anti-skid inoperative
can be found in the non-normal portion of this section.
Destination Airport ---------- AAA
Field Elevation ---------- 4,000 ft.
Runway Length ---------- 7,000 ft.
Flap Setting ---------- 30
Anti-Skid ---------- Normal
Auto Ground Spoilers ---------- Normal
Forecast Temperature ---------- 27°C
Forecast Wind Dir./Vel. ---------- 070/10
Forecast Rwy Condition ---------- Dry
Approach Climb Limit Calculation (-300):
From the Approach Climb Limit Weight chart for landing flap 30, the maximum
approach climb limit weight at 4,000 ft. pressure altitude and 27°C is 129,600
lbs.
Runway Limit Calculation:
From the Runway Limit chart for flaps 30 degree landing, the zero wind
maximum weight at 4,000 ft. pressure altitude and 7,000 ft. runway length is
134,000 lbs. The headwind correction for flaps 30 is 370 lbs./knot. For 10
knots headwind, the correction is 10 x 370 or 3,700 lbs. The maximum runway
limit landing weight is then 134,000 + 3,700 = 137,700 lbs.
Answer:
The approach climb and runway limit weight are both well above the maximum
structural weight. Therefore, the maximum structural landing weight of
114,000 lbs. is the landing weight limit.
