Flight Crew Oxygen Requirements
This airplane is equipped with a chemical passenger oxygen system.
Regulations require that sufficient oxygen be provided to the flight crew to
account for the greater of supplemental breathing oxygen in the event of a
cabin depressurization or protective breathing in the event of smoke or
harmful fumes in the flight deck. The oxygen quantity associated with the
above requirements is achieved with the minimum dispatch oxygen
cylinder pressure.
To determine the minimum dispatch oxygen cylinder pressure enter the
appropriate flight crew oxygen table with the number of crew plus
observers using oxygen and read the minimum cylinder pressure required
for the appropriate cylinder temperature.
Net Level Off Weight
The Net Level Off Weight table is provided to determine terrain clearance
capability in straight and level flight following an engine failure.
Regulations require terrain clearance planning based on net performance
which is the gross (or actual) gradient performance degraded by 1.1%. In
addition, the net level off pressure altitude must clear the terrain by
1000 ft.
To determine the maximum weight for terrain clearance, enter the table
with required net level off pressure altitude and expected ISA deviation to
obtain weight. Adjust weight for anti-ice operation as noted below the
table.
Landing
Tables are provided for determining the maximum landing weight as
limited by field length or climb requirements for a single landing flap.
Maximum landing weight is the lowest of the field length limit weight,
climb limit weight, or maximum certified landing weight.
Landing Field Limit Weight
For the expected runway condition and anti-skid system configuration,
obtain wind corrected field length by entering the Wind Corrected Field
Length table with field length available and wind component along the
runway. Now enter the Field Limit Weight table with wind corrected field
length and pressure altitude to read field limit weight.
