MOC VTOL.2430(a)(6) Energy
retention capability in an emergency landing
n/a
1. General
MOC VTOL.2325(a)(4) provides an accepted means of compliance with VTOL.2430(a)(6) regarding the energy retention capability of the energy storage and distribution system during a survivable emergency landing on land.
2. Specific considerations for VTOL capable aircraft with an electrical energy storage and distribution system
In addition to Section 1 of this MOC, the following applies for VTOL capable aircraft with an electrical energy storage and/or distribution system:
(a) For VTOL capable aircraft that are certified as per VTOL.2310 for intended operations on water, for emergency flotation or for ditching, MOC VTOL.2325(a)(4) with the following changes constitutes an accepted means of compliance with VTOL.2430(a)(6) regarding the energy retention capability of the energy storage and distribution system during a survivable emergency landing on water:
(1) In Section 3(b) of MOC VTOL.2325(a)(4): the drop impact surface should be water. Conservatively a non-deforming surface may be used.
(2) In Section 5 (d)(1) of MOC VTOL.2325(a)(4): persons on ground include all persons in contact with the VTOL, including persons in the water. The electrical energy storage and distribution system should retain the stored electrical energy for at least 15 minutes.
(b) For VTOL capable aircraft certified for continued operations over water without meeting the flotation categories under VTOL.2310, MOC VTOL.2325(a)(4) with the following change constitutes an accepted means of compliance with VTOL.2430(a)(6) regarding the energy retention capability of the energy storage and distribution system during a survivable emergency landing on water:
(1) In Section 3(a) of MOC VTOL.2325(a)(4): the drop height may be reduced to 6 m
