Can individual equipment requirements for flight and navigational instruments be met by integrated flight systems or electronic displays?

Yes, individual equipment requirements may be met by combinations of instruments, by integrated flight systems, or by a combination of parameters on electronic displays, provided the information available to each required pilot is not less than that required in the applicable operational requirements and the equivalent safety of the installation is approved during type certification.

For which rotorcraft operations does AMC1 NCO.IDE.H.120 and NCO.IDE.H.125 specify the approval of equivalent safety for integrated instrument installations?

The approval is for the intended type of operation of the rotorcraft, which in the context of this AMC is operations under VFR and operations under IFR.

AMC1 NCO.IDE.H.120 & NCO.IDE.H.125 Operations under VFR & operations under IFR -- flight and navigational instruments and associated equipment

Q: What must be approved during type certification for an integrated flight system installation to be used under VFR or IFR?

The equivalent safety of the installation must be approved during the type certification of the rotorcraft for the intended type of operation.

Q: When using integrated flight director systems for turn and slip, attitude, and heading, what safeguard must be retained?

The safeguards against total failure inherent in the three separate instruments must be retained.

Q: What is the minimum information that must be available to each required pilot when individual equipment requirements are met by combinations of instruments or electronic displays?

The information available to each required pilot should not be less than that required in the applicable operational requirements.

Q: Does the AMC allow the means of measuring and indicating turn and slip, attitude, and heading to be combined into a single integrated flight director system?

Yes, the means of measuring and indicating turn and slip, rotorcraft attitude, and stabilised rotorcraft heading may be met by combinations of instruments or by integrated flight director systems, provided that the safeguards against total failure inherent in the three separate instruments are retained.

INTEGRATED INSTRUMENTS

(a) Individual equipment requirements may be met by combinations of instruments, by integrated flight systems or by a combination of parameters on electronic displays. The information so available to each required pilot should not be less than that required in the applicable operational requirements, and the equivalent safety of the installation should be approved during the type certification of the rotorcraft for the intended type of operation.

(b) The means of measuring and indicating turn and slip, rotorcraft attitude and stabilised rotorcraft heading may be met by combinations of instruments or by integrated flight director systems, provided that the safeguards against total failure, inherent in the three separate instruments, are retained.
