Can individual flight instrument requirements for helicopters under VFR and IFR be met by integrated flight systems or electronic displays?

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

Is approval required for an integrated flight system installation used to meet helicopter instrument requirements, and if so, when and for what?

Yes, the equivalent safety of the installation must be approved during type certification of the helicopter for the intended type of operation.

Q: What condition must be met when using integrated flight systems to satisfy the individual equipment requirements for helicopter VFR and IFR operations?

The information available to each required pilot must not be less than that required in the applicable operational requirements, and the equivalent safety of the installation must be approved during type certification of the helicopter for the intended type of operation.

Q: How may the means of measuring and indicating slip, helicopter attitude, and stabilised helicopter heading be met according to AMC1 NCC.IDE.H.120 and NCC.IDE.H.125?

They 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.

Q: What safeguard must be retained when using an integrated flight director system to provide slip, attitude, and heading indications?

INTEGRATED INSTRUMENTS

(a) Individual equipment requirements may be met by combinations of instruments or 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 type certification of the helicopter for the intended type of operation.

(b) The means of measuring and indicating slip, helicopter attitude and stabilised helicopter 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.
