What is the starting point for measuring the projected horizontal distance of the TODRV?

The TODRV is measured from the start of a take-off procedure.

Does the definition of TODRV for a vertical take-off (VTO) use the take-off surface as the reference for the 10.7 m (35 ft) height?

No, for a vertical take-off (VTO), the 10.7 m (35 ft) height is referenced to the high hover height (h2) established in the AFM, not the take-off surface.

What is the minimum climb gradient required for the VCA at the point where the TODRV ends for a conventional take-off?

The minimum climb gradient required is 4.5 % for a conventional take-off.

For which take-off type does the TODRV definition include a 'dropdown segment'?

The dropdown segment is included in the TODRV definition for an elevated conventional take-off (eConvTO).

What is the height above the take-off surface that the VCA must reach for an elevated conventional take-off (eConvTO) to define the TODRV?

For an elevated conventional take-off (eConvTO), the VCA must reach 10.7 m (35 ft) above the take-off surface.

What is the high hover height (h2) used in the TODRV definition for a vertical take-off?

The high hover height (h2) is the height established in the AFM.

Is the TODRV defined as a vertical distance or a horizontal distance?

The TODRV is defined as a projected horizontal distance.

For a vertical take-off (VTO), what is the minimum climb gradient required at the point where the VCA reaches 10.7 m (35 ft) above h2?

The minimum climb gradient required is 4.5 % for a vertical take-off (VTO).

What is the difference in the reference height for the 10.7 m (35 ft) obstacle clearance between a conventional take-off and a vertical take-off?

For a conventional take-off, the 10.7 m (35 ft) is above the take-off surface, while for a vertical take-off, it is above the high hover height (h2) established in the AFM.

Does the TODRV definition for an elevated conventional take-off (eConvTO) require the VCA to reach 10.7 m (35 ft) before or after the dropdown segment?

The VCA must reach 10.7 m (35 ft) after the dropdown segment for an elevated conventional take-off (eConvTO).

What is the applicability date of the ED Decision associated with GM2 UAM.POL.VCA.120?

The section does not state an applicability date; it only references ED Decision 2025/010/R.

What is the definition of the take-off distance required for a vertical take-off (TODRV) in terms of obstacle clearance and height?

For a vertical take-off (VTO), the TODRV is the projected horizontal distance from the start of a take-off procedure to the point where the VCA reaches 10.7 m (35 ft) above the high hover height (h2) established in the AFM, with the minimum climb gradient of 4.5 %.

How is the take-off distance required (TODRV) defined for an elevated conventional take-off (eConvTO)?

For an elevated conventional take-off (eConvTO), the TODRV is the projected horizontal distance from the start of a take-off procedure to the point where, after the dropdown segment, the VCA reaches 10.7 m (35 ft) above the take-off surface with the minimum climb gradient of 4.5 %.

What is the minimum climb gradient used in the definition of the take-off distance required (TODRV) for all take-off types?

The minimum climb gradient used in the definition of the TODRV is 4.5 % for all take-off types (conventional, elevated conventional, and vertical take-off).

In the definition of TODRV for a vertical take-off (VTO), what is the reference height for the 10.7 m (35 ft) obstacle clearance?

For a vertical take-off (VTO), the 10.7 m (35 ft) height is measured above the high hover height (h2) established in the AFM.

For an elevated conventional take-off (eConvTO), what specific segment must occur before the VCA reaches the 10.7 m (35 ft) height?

For an elevated conventional take-off (eConvTO), the dropdown segment must occur before the VCA reaches 10.7 m (35 ft) above the take-off surface.

GM2 UAM.POL.VCA.120 Take-off

ED Decision 2025/010/R

APPLICATION OF TODRV

The TODRV provides safe obstacle clearance following a CFP being recognised at TDP. It is the projected horizontal distance from the start of a take-off procedure to:

(a) the point where the VCA reaches 10,7 m (35 ft) above the take-off surface with the minimum climb gradient of 4.5 %, for a conventional take-off (ConvTO);

(b) the point where, after the dropdown segment, the VCA reaches 10,7 m (35 ft) above the take-off surface with the minimum climb gradient of 4.5 %, for an elevated conventional take-off (eConvTO);

(c) the point where the VCA reaches 10,7 m (35 ft) above the high hover height (h2) established in the AFM with the minimum climb gradient of 4.5 %, for a vertical take-off (VTO).
