START OF TAKEOFF ROLL
An estimate of the horizontal distance required to clear an obstacle up to 1,500 feet above the runway, or the required climb gradient to clear an obstacle along the takeoff flight path, may be obtained by using Figures 4E-5 through 45E-10. The takeoff flight path is as follows:
1,500 FEET
35 FT SECOND SEGMENT CLIMB (FIGURES 4E-6 AND 4E-7)
SECOND SEGMENT ACCELERATION (FIGURE 4E-8)
THIRD SEGMENT CLIMB (FIGURES 4E-9 AND 4E-10)
The takeoff flight path consists of four phases defined as follows: 1. SINGLE ENGINE TAKEOFF DISTANCE TO 35 FOOT HEIGHT (FIGURE 4E-5). Both engines are assumed to operate normally to speed V1 where one engine is recognized as failed and the takeoff is continued on one engine. This phase ends when the airplane reaches 35 feet above the runway surface at V2. 2. SECOND SEGMENT CLIMB (FIGURES 4E-6 and 4E-7). The second segment climb is a constant V2 climb starting at a height of 35 feet above the runway surface and ends at a height of 400 feet above the runway. The landing gear is fully retracted at the start of this phase, flaps remain at 1/4, and the propeller on the inoperative engine is windmilling in the NTS mode. Figures 4E-6 and 4E-7 present net climb gradient.

METRO III – ICAO ANNEX 8 TAKEOFF FLIGHT PATH DISTANCE TO 1500 FOOT HEIGHT – WET (continued) 3. SECOND SEGMENT ACCELERATION (FIGURE 4E-8). This phase is an acceleration at 400 feet height from V2 to VYSE. The flaps are retracted at V2 +5 knots, the propeller on the inoperative engine is feathered, and takeoff power is maintained until VYSE is obtained. 4. THIRD SEGMENT CLIMB (FIGURE 4E-9 and 4E-10). The third segment climb is at VYSE with maximum continuous power set. It starts at 400 feet and is completed at 1500 feet above the runway surface. Figures 4E-9 and 4E-10 present net climb gradient. The following are three examples to illustrate the use of the flight path data charts. EXAMPLE 1 – DETERMINATION OF TOTAL DISTANCE TO 1500 FEET Given:
OAT = 10°C Airport Pressure Altitude = 2000 feet Gross Weight = 15,000 pounds (6805 kg) Headwind = 20 knots Runway Slope = 1 percent (uphill) Engine Anti-ice off
Obtain: 1. Single Engine Takeoff Distance to 35 Foot Height (Figure 4E-5) = 4,950 feet (1510 meters). 2. Second Segment Climb Gradient (Figure 4E-6) = 5.5%. 3. Enter Figure 4E-7 at 400 feet and proceed to 5.5%. Obtain 6,620 feet (2020 meters) to climb to 400 feet. 4. Second Segment Acceleration Distance (Figure 4E-8) = 3,800 feet (1160 meters) to accelerate from V2 to VYSE. 5. Third Segment Climb Gradient (Figure 4E-9) = 3.3%. 6. Enter Figure 4E-10 at 1500 feet and proceed to 3.3%. Obtain 33,500 feet (10210 meters) to climb from 400 feet to 1500 feet. 7. Total Distance is: 4,950 feet (1510 6,620 feet (2020 3,800 feet (1160 33,500 feet (10210 48,870 feet (14900

METRO III – ICAO ANNEX 8 TAKEOFF FLIGHT PATH DISTANCE TO 1500 FOOT HEIGHT – WET (continued) EXAMPLE 2 – CLOSE IN OBSTACLE CLEARANCE Given:
OAT = 10°C Airport Pressure Altitude = 2,000 feet Gross Weight = 15,000 pounds (6805 kg) Headwind = 20 knots Runway Slope = 1 percent (uphill) Engine Anti-ice off Obstacle Height = 350 feet* (107 meters) Obstacle Distance From Brake Release = 18,950 feet (5775 meters)
Obtain: 1. Single Engine Takeoff Distance to 35 Foot Height (Figure 4E-5) = 4,950 feet (1510 meters). 2. Obstacle horizontal distance from the 35 foot height point equals the total obstacle distance minus the distance to 35 feet height. 18,950 – 4,950 = 14,000 feet (4265 meters). 3. Second Segment Climb Gradient (Figure 4E-6) = 5.5%. 4. To obtain the required climb gradient to clear the close in obstacle, enter Figure 4E-7 at 350 feet* and at 14,000 feet distance. Obtain required climb gradient of 2.25%. 5. Since the required gradient, 2.25%, is less than the actual gradient, 5.5%, this obstacle will be cleared. *NOTE This example computes the horizontal distance to climb to the obstacle height of 350 feet. To provide additional clearance above the obstacle (e.g., 35 feet), the desired additional clearance must be added to the obstacle height before entering Figure 4E-7.

OAT = 10°C Airport Pressure Altitude = 2,000 feet Gross Weight = 15,000 pounds (6805 kg) Headwind = 20 knots Runway slope = 1 percent (uphill) Engine Anti-ice off Obstacle Height = 700 feet* (213 meters) Obstacle Distance from Brake Release = 30,370 feet (9255 meters)
Obtain: 1. Single Engine Takeoff Distance to 35 Foot Height (Figure 4E-5) = 4,950 feet (1510 meters). 2. Second Segment Climb Gradient (Figure 4E-6) = 5.5%. 3. Enter Figure 4E-7 at 400 feet and proceed to 5.5%. Obtain 6,620 feet (2020 meters) to climb to 400 feet. 4. Second Segment Acceleration Distance (Figure 4E-8) = 3,800 feet (1160 meters) to accelerate from V2 to VYSE. 5. The horizontal distance from the end of the second segment acceleration to the obstacle equals 30,370 – 4,950 – 6,620 – 3,800 = 15,000 feet (4570 meters). 6. Enter Figure 4E-10 at 700 feet* height and 15,000 feet distance. Obtain required gradient of 2.0%. 7. The Third Segment Climb Gradient (Figure 4E-9) = 3.3%. 8. Since the required gradient, 2.0%, is less than the actual gradient of 3.3%, the obstacle will be cleared. *NOTE This example computes the horizontal distance to climb to the obstacle height of 700 feet. To provide additional clearance above the obstacle (e.g., 35 feet), the desired additional clearance must be added to the obstacle height before entering Figure 4E-10.
