How many total masks are allocated to the crew in the cabin?

The allocation of masks to the crew in the cabin is typically determined by safety regulations and the specific configuration of the aircraft. In many commercial aircraft, including EJets, it is common to have three total masks allocated for the cabin crew. This is designed to ensure that if there is a sudden loss of cabin pressure or an emergency situation that requires the use of oxygen masks, all crew members can be adequately provided for.

This allocation allows for one mask on each cabin crew member's station, ensuring that they have immediate access to oxygen in an emergency. Providing three masks accommodates situations where crew members may need to assist passengers while also ensuring their own safety, which is crucial during an emergency evacuation or critical situation. The number accounts for maintaining operational control by having enough masks for all crew members while also considering the dynamics of cabin operations.
