| (b) | Class 2 helicopter - a helicopter with performance such that, in case of critical power unit failure, the helicopter is able to safely continue the flight, except when the failure occurs early during the take-off manoeuvre or late in the landing manoeuvre, in which case a forced landing may be required; and |
| (c) | Class 3 helicopter - a helicopter with performance such that, in case of power unit failure at any point in the flight profile, a forced landing has to be performed. |
