MOC VTOL.2605 Installation and operation information
n/a
(a) CS 27.1322 Amdt 6, as per the guidelines established in AC 27.1322, and with further advice provided in AMC 25.1322, is accepted as a means of compliance with VTOL.2605(b) regarding the design of warnings, cautions and advisory lights.
(b) CS 27.1302 Amdt. 8, as per the guidelines established in AMC 27.1302, is accepted as a means of compliance with VTOL.2605(b) and (c) regarding the design of flight crew interfaces and behaviour of installed systems and equipment used by the flight crew in the cockpit while operating the VTOL capable aircraft in normal, abnormal abnormal/malfunction and emergency conditions.
(1) The functions that the flight crew members perform from the cabin should be considered if they can interfere with the ones under the responsibility of the cockpit flight crew, or if dedicated airworthiness requirements apply.
(2) CS 27.1302 and its AMC 27.1302 do not apply to flight crew training, qualification, or licensing requirements.
(3) The extent of the compliance demonstration necessary for each design may vary and not all the material contained in this MOC has to be systematically followed. The proportionate application of AMC 27.1302 will depend on criteria such as VTOL category (Enhanced and Basic) and the maximum passenger seating configuration.
|
Explanatory Note: The Categories Basic and Enhanced were introduced in the Special Condition to allow proportionality in safety objectives. It is considered that the safety objectives for CS-25 and CS-27/29 aircraft should be maintained as a minimum for VTOL capable aircraft in the Category Enhanced, i.e. intended for operations over congested areas or for commercial air transport of passengers. The same approach is followed in the implementation of Human Factors during the design and certification processes of VTOL cockpits. |
For the Category Basic, proportionality is allowed in the application of AMC 27.1302 as defined in this MOC VTOL.2605.
(4) The following proportional approach in the application of AMC 27.1302 supersedes AMC 27.1302 paragraph 3.2.9 “Proportional approach in the compliance demonstration”:
|
|
Maximum Passenger Seating Configuration |
Proportionality |
|
Category Enhanced |
- |
Applicants for a VTOL capable aircraft should follow all provisions in AMC 27.1302. |
|
Category Basic |
7 to 9 passengers |
Applicants for a VTOL capable aircraft should follow all provisions in AMC 27.1302. |
|
2 to 6 passengers |
Applicants for a VTOL capable aircraft are: ii. not required to develop a dedicated HFs test programme and iii. allowed to use single occurrence of a test for compliance demonstration; |
|
|
0 to 1 passenger |
Applicants for a VTOL capable aircraft are: iv. not required to develop a dedicated HFs test programme; iv. allowed to use single occurrence of a test for compliance demonstration; v. allowed to use a single crew to demonstrate the HFs scenario based assessments. |
(c) CS 27.1561 Amdt. 5 (or later) is accepted as a means of compliance with VTOL.2605(d) regarding the identification of information related to safety equipment and the marking of its method of operation.
VTOL aircraft installation and operation information requires specific warning light designs and flight crew interface considerations. Compliance involves established guidelines for cockpit systems during normal, abnormal, and emergency conditions. Human factors testing proportionality depends on VTOL category (Enhanced/Basic) and passenger capacity, with reduced testing for smaller Basic category aircraft. Safety equipment information must be clearly identified.
