NET TAKE-OFF FLIGHT PATH
ILLUSTRATED EXAMPLES
Figure 5.25.1 shows two examples of the use of the flight path charts. A further example where
only the second segment needs to be considered is also provided.
Example 1
From Figure 5.25.5 the height above Reference Zero at the three and a half minute point is
1100 feet. Also from this Figure the Horizontal Distance from Reference Zero:
• To the three and a half minute point is 51,500 feet.
• To achievement of final take-off climb speed is 71,000 feet.
• To reach 1500 feet is 86,500 feet.
The flight path to 1500 feet is shown on Figure 5.25.1. It may be extended to the point at which
en-route climb speed is achieved as follows:
• With the lapse rate resulting in a 3° C lower temperature, the fourth segment (Final Take-0ff
Climb) net gradient from Figure 5.55.3 is 2.4% at 1500 feet above the airfield.
• Figure 5.25.6 then gives a fifth segment acceleration distance of 16,000 feet.
Therefore, the total distance to the point at which en-route climb speed is achieved is
86,500 +16,000 = 102,500 feet from Reference Zero.
