NET TAKE-OFF FLIGHT PATH
Using Figure 5.25.5, this example comes in the area where acceleration takes place at 1500
feet and the Horizontal Distance from Reference Zero:
• To 1500 feet is 36,500 feet.
• To achieve final take-off climb speed is 46,000 feet.
The flight path to the point at which final take-off climb speed is achieved is shown on Figure
5.25.1. It may be extended to the point at which en-route climb speed is achieved, using the
same method as in Example 1, the fourth segment net gradient is 3.35% (at 9500 feet, 16
°
C)
and the fifth segment acceleration distance is 10,400 feet.
Therefore, the total distance to the en-route climb speed is 46,000 + 10,400 = 56,400 feet.
Example 3
In a case where only the second segment needs to be considered, and particularly where the
obstacles are close in, it may be more convenient to obtain points on the flight path by using
the second segment net gradient charts, Figures 5.25.2 and 5.25.4.
Find the height of the flight path at 1000 feet from Reference Zero. The second segment
gradient is found from Figure 5.25.4 to be 4.5%.
Then the height gained in the second segment
= 4.5 x 1,000 = 45 feet
100
and the height above Reference Zero
= 45 + 35 = 80 feet
NOTE: If the height gained during the second segment climb is significant, then the
gradient must be read at the mean altitude during the climb allowing a
temperature reduction of 2° C for every 1000 feet altitude above the airfield.
