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 4C-6 through 4C-11. The takeoff flight path is as follows:

1,500 FEET (457 m)

35 FT (10.7 m) SECOND SEGMENT CLIMB (FIGURES 4C-7 AND 4C-8)

SECOND SEGMENT ACCELERATION (FIGURE 4C-9)

THIRD SEGMENT CLIMB (FIGURES 4C-10 AND 4C-11)

The takeoff flight path consists of four phases defined as follows: 1. SINGLE ENGINE TAKEOFF DISTANCE TO 35 FOOT HEIGHT (FIGURE 4C-6).

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 4C-7 and 4C-8).

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 4C-7 and 4C-8 present net climb gradient.

FAA APPROVED: MAY 22/89

METRO III ICAO ANNEX 8 TAKEOFF FLIGHT PATH DISTANCE TO 1500 FOOT HEIGHT – DRY, BLEED AIR ON (continued) 3. SECOND SEGMENT ACCELERATION (FIGURE 4C-9).

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 4C-10 and 4C-11).

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 4C-10 and 4C-11 present net climb gradient.

The following are three examples to illustrate the use of the flight path data charts.

EXAMPLE 1 Ð DETERMINATION OF TOTAL DISTANCE TO 1500 FEET Given:

OAT = 10oC Airport Pressure Altitude = 2000 feet Gross Weight = 13,000 pounds (5900 kg) Headwind = 20 knots Runway Slope = 1 percent (uphill) Engine Anti-ice off

Obtain: 1. Single Engine Takeoff Distance to 35 Foot Height (Figure 4C-6) = 4,975 feet (1515 meters).

2. Second Segment Climb Gradient (Figure 4C-7) = 4.9%.

3. Enter Figure 4C-8 at 400 feet and proceed to 4.9%. Obtain 7,450 feet (2270 meters) to climb to 400 feet.

4. Second Segment Acceleration Distance (Figure 4C-9) = 3,750 feet (1145 meters) to accelerate from V2 to VYSE. 5. Third Segment Climb Gradient (Figure 4C-10) = 4.9%.

6. Enter Figure 4C-11 at 1500 feet and proceed to 4.9%. Obtain 22,500 feet (6860 meters) to climb from 400 feet to 1500 feet.

7. Total Distance is: 4,975 feet (1515 meters) 7,450 feet (2270 meters) 3,750 feet (1145 meters) 22,500 feet (6860 meters) 38,675 feet (11790 meters)

METRO III ICAO ANNEX 8 TAKEOFF FLIGHT PATH DISTANCE TO 1500 FOOT HEIGHT – DRY, BLEED AIR ON (continued) EXAMPLE 2 Ð CLOSE IN OBSTACLE CLEARANCE Given:

OAT = 10oC Airport Pressure Altitude = 2,000 feet Gross Weight = 13,000 pounds (5900 kg) Headwind = 20 knots Runway Slope = 1 percent (uphill) Engine Anti-ice off Obstacle Height = 350 feet* (107 meters) Obstacle Distance From Brake Release = 18,975 feet (5785 meters)

Obtain: 1. Single Engine Takeoff Distance to 35 Foot Height (Figure 4C-6) = 4,975 feet (1515 meters).

2. Obstacle horizontal distance from the 35 foot height point equals the total obstacle distance minus the distance to 35 feet height. 18,975 Ð 4,975 = 14,000 feet (4265 meters).

3. Second Segment Climb Gradient (Figure 4C-7) = 4.9%.

4. To obtain the required climb gradient to clear the close in obstacle, enter Figure 4C-8 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, 4.9%, 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 4C-8.

Obtain: 1. Single Engine Takeoff Distance to 35 Foot Height (Figure 4C-6) = 4,975 feet (1515 meters).

2. Second Segment Climb Gradient (Figure 4C-7) = 4.9%.

3. Enter Figure 4C-8 at 400 feet and proceed to 4.9%. Obtain 7,450 feet (2270 meters) to climb to 400 feet.

4. Second Segment Acceleration Distance (Figure 4C-9) = 3,750 feet (1145 meters) to accelerate from V2 to VYSE. 5. The horizontal distance from the end of the second segment acceleration to the obstacle equals 31,175 Ð 4,975 Ð 7,450 Ð 3,750 = 15,000 feet (4570 meters).

6. Enter Figure 4C-11 at 700 feet* height and 15,000 feet distance. Obtain required gradient of 2.0%.

7. The Third Segment Climb Gradient (Figure 4C-10) = 4.9%.

8. Since the required gradient, 2.0%, is less than the actual gradient of 4.9%, 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 4C-11.
