## GM1 ADR.OPS.D.065 Engine test

GENERAL

(a) Where possible, engine tests are performed at designated remote areas.

(b) Engine run-ups at or above idle power are not permitted in cul-de-sacs, or in areas where the jet efflux would affect stands, equipment areas or work areas.

(c) Engine tests approved at stands in regular use at the [apron](https://avioverse.aero/glossary/easa/apron) should be limited to check starts and idle power only.

(d) Where engine tests are permitted to be performed at the apron, a remote area should be selected where the jet blast will not affect other apron areas and busy taxiways.

(e) Where necessary, engine tests are safeguarded by ground personnel that arrange for any rear of stand roads and, if needed, sections of the [taxiway](https://avioverse.aero/glossary/easa/taxiway) to be closed.

(f) The area behind and adjacent to the cone(s) of the blast will be clear of equipment and the ground must be firm and without loose tarmac, stones or other material.
