Operational Credit

With effect from 26 August 2020, the Registry is pleased to announce a number of enhancements to the AWOPS Approval available for M- Registered Aircraft.

  1. EVS/HUD becomes Operational Credit

The IOMAR has introduced the approval of “Operational Credit”.

Traditionally aerodrome operating minima has been strictly limited by the type of instrument approach procedure and the category of operation performed. However, ICAO now recognises the possibility of granting operational credits for operations with aeroplanes carrying suitable additional equipment through the concept of Operational Credit: -

Annex 6 Part II: “The State of Registry may approve operational credit(s) for operations with aeroplanes equipped with automatic landing systems, a HUD or equivalent displays, EVS, SVS or CVS.  Such approvals shall not affect the classification of the instrument approach procedure.”

Previously, the IOMAR enabled the use of EVS/HUD technology by issuing an aircraft specific exemption from the Air Navigation (Isle of Man) Order 2015 to allow the aircraft to descend to 100ft above the runway threshold elevation.

However, the IOMAR has now introduced the approval of “Operational Credit” as an AWOPS Approval issued as an entry on the aircraft’s Operations Specification.

All Operators with a current Exemption to use the EVS/HUD will receive (at no cost to the operator) a new Operations Specification to replace the old EVS/HUD Exemption with the new ‘Operational Credit to descend below DH/MDH to 100ft above threshold elevation with RVR not less than 350m’ approval over the next few weeks.

  1. Operational Credit to Touchdown and Rollout.

Operators of applicable Gulfstream aircraft whose pilots have satisfactorily completed the Gulfstream EFVS to Touchdown and Rollout Pilot Training course can now apply for AWOPS Operational Credit approval to use the EVS/HUD to touchdown and rollout with an RVR of not less than 350m.

Gulfstream have recently received airworthiness certification to use the EVS/HUD to touchdown and rollout. Subject to State of Registry approval, this enables the PIC to use the EVS system to obtain one of the required visual references and thus exploit the safety benefits of enhanced situational and positional awareness.

Operators with a current Exemption to use the EVS/HUD to descend to 100ft above the runway threshold elevation must submit an application to the IOMAR if they require to also use the EVS/HUD to touchdown and rollout.  Without this explicit approval, the PIC must continue to obtain the required visual references without reliance on the EVS system.

  1. Guidance Material

With the introduction of Operational Credit as an AWOPS approval, the Registry has withdrawn RP44 and Form 44.

All guidance material for AWOPS, including the new Operational Credit are included in the latest edition of RP39 dated 26 August 2020, which is available on our website.  Operators applying for any AWOPS approval should use Form 39.

The Registry trusts that these enhancements will be beneficial to the operator of M- Registered aircraft, and welcome any feedback to [email protected].

Yours sincerely,

The Flight Operations Team
