Safety Issue Description

Microflite had not published an inadvertent instrument meteorological conditions (IIMC) recovery procedure for their day visual flight rules pilots and their IIMC recovery training was not mandatory. The provision of this procedure and training would have reduced the risk of a loss of attitude control following an IIMC encounter.

Issue Status Justification

The ATSB acknowledges Microflite has published an inadvertent instrument meteorological conditions (IIMC) recovery procedure for their day visual flight rules pilots but will only conduct the training element of this safety issue on a resource availability basis. However, as the IIMC training is not guaranteed for all the operator’s pilots, the safety issue of reducing the risk of loss of attitude control following an IIMC encounter is only partially addressed.

Action description

On 6 April 2023, Microflite advised the ATSB it was introducing their inadvertent instrument meteorological conditions recovery training to their day visual flight rules pilots.

On 21 November 2023, Microflite advised the ATSB it has amended their Flying Operations Manual to include a recovery procedure for pilots to follow during inadvertent entry into IMC. Furthermore:

Microflite does not intend to mandate training for inadvertent entry into IMC for all day VFR Pilots in unstabilised single-engine VFR helicopters. While the potential benefits of such a policy are understood, introducing this requirement for all pilots is impractical and uncommercial, as:
a. such training is not required by the current regulations
b. the perishable nature of this training means that one-off licencing/training is insufficient – annual training and regular competency checks are required; and
c. there is an insufficient number of instrument-rated instructors and aircraft available to service the single-engine Day VFR environment.
Microflite will (in excess of its regulatory obligations) implement such training where appropriate and will continue to emphasise ICARUS device training and improved decision making for pilots (including non-IFR pilots) who operate these aircraft.
