What specific times are listed as examples that may be included when calculating 'FSTD support time' under AMC1 ORA.FSTD.100(d)?

For calculation of the metrics as referred to in point (b) of AMC1 ORA.FSTD.100(d), 'FSTD support time' may include: out of service (closure of the training centre, scheduled out of service because of major update); maintenance (preventative and corrective); engineering (development, improvement of the FSTD); regulatory (authority evaluation, QTG rerun, activities under point ORA.FSTD.225, fly-out); configuration (change of configuration, time between two FSTD sessions, etc.).

According to the guidance, what does the 'FSTD downtime' metric cover, and can it occur outside scheduled training hours?

'FSTD downtime' is a metric that can occur during scheduled training or even when the training is not impacted. It takes into account all events that could affect the availability of the FSTD.

Are these FSTD performance metrics guidance provisions (GM1 ORA.FSTD.100(d)) applicable as of 1 October 2026, and if not, what is the stated applicability date?

The content of this Guidance Material is applicable from 30 April 2028 per ED Decision 2026/006/R.

GM1 ORA.FSTD.100(d) General

Q: How can an FSTD operating organisation use performance metrics to support an extension of the recurrent evaluation period with the competent authority?

Yes, the performance metrics may be used by the organisation operating the FSTD to demonstrate to the competent authority: (1) the performance of an FSTD to facilitate the competent authority's assessment on extension of the recurrent evaluation period of the FSTD; and (2) the effectiveness of its management system with regard to FSTD operation and maintenance.

ED Decision 2026/006/R

FSTD PERFORMANCE METRICS

(a) Organisations should develop and maintain a consistent methodology to calculate and report performance metrics. These values are not only a means to demonstrate compliance with point ORA.FSTD.100(d) but also form part of the organisation’s management system for ensuring continued FSTD performance. This data can also inform proactive maintenance decisions and support dialogue with FSTD users, FSTD providers and competent authorities.

(b) The performance metrics may be used by the organisation operating the FSTD to demonstrate to the competent authority:

(1) the performance of an FSTD to facilitate the competent authority’s assessment on extension of the recurrent evaluation period of the FSTD;

(2) the effectiveness of its management system with regard to the FSTD operation and maintenance.

(c) For calculation of the metrics as referred to in point (b) of AMC1 ORA.FSTD.100(d), the following may serve as guidance:

(1) ‘FSTD support time’ may include the following times:

(i) out of service: closure of the training centre, scheduled out of service because of major update;

(ii) maintenance: preventative and corrective;

(iii) engineering: development, improvement of the FSTD;

(iv) regulatory: authority evaluation, QTG rerun, activities under point ORA.FSTD.225, fly-out;

(v) configuration: change of configuration, time between two FSTD sessions, etc.

(2) ‘FSTD downtime’ can be during scheduled training or even when the training is not impacted. This metric takes into account all events that could affect the availability of the FSTD.

(3) ‘External failure time’ is time lost during planned available time due to external factors such as facility related causes; operator/user causes; scheduling/logistical causes; environmental or external disruptions.
