When completing the Tech Log after a simulator session how often do you give the full story. For example, I have seen "Gear operating slowly" but the tech log did not give details of airspeed, altitude, QNH, OAT, hydraulic systems serviceability etc. etc. All these are included in the gear operating speed model.
One item NOT included in the standard sim tech toolkit is a crystal ball.
If there is a problem, most sim tech are happy to talk it over with you (a good substitute for the crystal ball) but how often do you call them rather than write some cryptic (and often illegible) comment in the tech log before disappearing out the door.
