Discrepancy (emergency procedures)

DISCREPANCY PROCEDURES

These procedures deal with what should be done in the event of conflicting reports surrounding a situation.

ASTRONAUT REPORTS HAZARD

In Contradiction to Instruments

When an astronaut reports a hazard in contradiction to instruments, believe the astronaut. Proceed to react according to reported hazard. After the reported hazard has been remedied, proceed with the instrument re-calibration procedure (pending).

In Contradiction to Video Feed

When an astronaut reports a hazard in contradiction to video feed, believe the astronaut. Proceed to evacuate astronauts from the hazard location. Attempt to verify hazard on video feed. If you can identify the hazard on video, proceed as normal. If you cannot identify the hazard on video follow P5.1.1 with the exceptions that follow.

When the astronauts go on repair EVA, ensure that the EVAs locate the hazard for Mission Control visually on camera. If Mission Control can identify the hazard on camera, treat the situation as a standard repair EVA with no follow up. If Mission Control cannot identify the hazard on camera, treat the situation as a standard repair EVA. but follow up with a camera check. In both cases, no instrument recalibration should be necessary.

In Contradiction to Mission Control Staff

When an astronaut reports a hazard in contradiction to Mission Control Staff, verify that this is not another situation. If it is in contradiction to Mission Control, believe the astronaut. Proceed to react according to the reported hazard. After the hazard has been remedied, explain to the Mission Control Staff that they are not in the habitat and so have a less perfect view of the environment.

In Contradiction to Another Astronaut

When an astronaut reports a hazard in contradiction to another astronaut report, evacuate astronauts from the hazard situation. Immediately attempt to determine if this is another situation. If it is not, proceed as if the hazard is real unless the reporting astronaut changes his statement and provides a reason that it was incorrect.

INSTRUMENT REPORTS HAZARD

In Contradiction to Astronaut

When an instrument reports a hazard in contradiction to an astronaut opinion, believe the instrument, and evacuate the astronauts from the hazard situation. The first EVA should be a hazard location/instrument repair EVA. The EVA should first attempt to determine if a hazard exists which corresponds to the instrument reading. If no such hazard exists, the EVA should attempt to perform the instrument replacement procedure (pending) on any instruments that may be malfunctioning.

In Contradiction to Another Instrument

When an instrument reports a hazard in contradiction to another instrument, evacuate the astronauts from the hazard location, and send an investigative EVA to determine if a hazard exists. If no hazard exists, call instrument failure procedure (pending)

ORDERS ISSUED BY GOVERNMENT OR OCESS COMMAND

Flight Director's response

The Flight Director must comply with orders issued by the government or OCESS Command, once they have been confirmed between the Habitat Commander and Mission Control Commander by means of activation codewords. The Flight Director may issue orders that aid or do not hinder government's/Command's orders, but will be overridden at the discretion of the Habitat Commander when the orders conflict directly.

Habitat Commander's response

The Habitat Commander must confirm any orders issued by government/Command with the Mission Control Commander by means of an activation codeword written on the orders and known only to the Mission Control Commander. Should the Flight Director's orders directly conflict with the written orders, once confirmed, the Habitat Commander is entitled to override the Flight Director, only for the purpose of completing the orders. Authority reverts to the Flight Director once the orders are carried out or the orders are no longer in conflict.
