Refer to figure.
The given table provides True Airspeed in Knots (KTAS) values only for pressure altitudes of 6000 ft and 8000 ft. Since the question requires KTAS at 7000 ft, interpolation is necessary.

1. Find the TAS at 6000 ft

1. Enter the table at a pressure altitude of 6000 ft.
2. Move horizontally across to the 2600 RPM.
3. Then continue to the right and read the corresponding TAS, which is 123 kt.

2. Find the TAS at 8000 ft

1. Enter the table at a pressure altitude of 8000 ft.
2. Move horizontally across to the 2600 RPM.
3. Then continue to the right and read the corresponding TAS, which is 119 kt.

3. Calculate the TAS at 7000 ft
Since 7000 ft lies midway between 6000 ft and 8000 ft, the average of the two values can be taken.

• TAS at 7000 ft = (TAS at 6000 ft + TAS at 8000 ft) / 2
• TAS at 7000 ft = 123 kt + 119 kt /2
• TAS at 7000 ft = 121 kt

Therefore, the answer is: 121 KTAS.

Note: KTAS is the same as TAS, but specifies that the unit is in knots.
