MH-60R Emergency Procedures Flashcards
The following should be performed for all emergencies..
- Maintain control of the aircraft
- Alert crew
- Determine the precise nature of the problem
- Complete the applicable emergency procedure or take action appropriate for the problem
- Determine landing criteria and land as required.
Land immediately
