Climb Requirements

After the aircraft has reached the 35 foot height with one engine
inoperative, there is a requirement that it be able to climb
at a specified climb gradient. This is known as the takeoff
flightpath requirement. The aircraft's performance must be
considered based upon a one-engine inoperative climb up to
1,500 feet above the ground. The takeoff flightpath profile
with required gradients of climb for the various segments
and configurations is shown in Figure 10-36.

NOTE: Climb gradient can best be described as being a
specific gain of vertical height for a given distance covered
horizontally. For instance, a 2.4 percent gradient means that
24 feet of altitude would be gained for each 1,000 feet of
distance covered horizontally across the ground.
The following brief explanation of the one-engine inoperative
climb profile may be helpful in understanding the chart in
Figure 10-36.
