Transport Safety and Operations Flashcards

A flight crew is responding to a night scene call for a motor vehicle collision. The ground crew describes a potential landing zone (LZ). Which of the following features described by the ground crew would be an immediate "no-go" for the landing?

Answer: Unidentified, unmarked power lines on one side.

Wires and unseen obstacles are one of the greatest dangers to helicopter operations, particularly during night landings at unprepared sites. A 5-degree slope is generally acceptable, tall grass can be managed, and a tree 150 feet away is outside the safety zone. Unseen wires present an unacceptable risk of a catastrophic accident.

According to FAA Part 135 regulations, the "sterile cockpit" rule must be maintained during which phases of flight?

Answer: During all critical phases of flight, including taxi, takeoff, landing, and all operations below 10,000 feet except cruise flight.

The sterile cockpit rule, mandated by FAA regulations FAR 121.542 and 135.100, prohibits non-essential conversations and activities during critical phases of flight. These phases are defined as taxi, takeoff, landing, and all other flight operations conducted below 10,000 feet, excluding cruise flight. This rule is designed to minimize distractions and allow the flight crew to focus on essential operational tasks.

While on a VFR flight, the helicopter unexpectedly enters a dense fog bank, and the pilot announces, "We are IIMC" (Inadvertent Instrument Meteorological Conditions). What is the immediate priority for the medical crew?

Answer: Communicate trust in the pilot, limit conversation, and prepare for unusual attitudes.

In an IIMC encounter, the pilot must immediately transition from visual flying to instrument flying. The medical crew's primary responsibility is to cease all non-essential activities, minimize conversation to avoid distracting the pilot, secure the patient and equipment, and trust the pilot's training to safely fly out of the condition. Attempting to find a visual path or performing non-essential communications can increase risk.

Which of the following statements best exemplifies the use of a key Crew Resource Management (CRM) principle during a critical phase of patient care in flight?

Answer: "That blood pressure seems low. Can we double-check the cuff size and placement before giving another vasodilator?"

Effective CRM involves using all available resources, including personnel, to promote safety and reduce errors by encouraging open communication, situational awareness, and teamwork. The statement in option A demonstrates cross-monitoring, inquiry, and advocacy by respectfully questioning a finding and suggesting a verification step. The other options demonstrate poor CRM, such as distracting the pilot, hierarchical decision-making, and overconfidence.

In the immediate aftermath of an aircraft accident, once personal safety is assured and the risk of fire is mitigated, what is the crew's highest priority according to survival training?

Answer: Activating the Emergency Locator Transmitter (ELT).

The primary goal after an aircraft crash, once immediate life threats like fire are addressed, is to ensure rescue. Activating the ELT or other signaling devices is the most critical step to alert search and rescue teams to the location. While shelter, water, and inventory are all important survival tasks, they are secondary to initiating the rescue process.

A flight request is received for an interfacility transport. The current weather at the departure base and the receiving facility is above the minimums required by the company's operational specifications. However, the pilot-in-command (PIC) declines the flight due to concerns about a rapidly developing weather system between the two locations. This decision is an example of:

Answer: The PIC's ultimate authority and responsibility for the safety of the flight.

The Pilot-in-Command (PIC) has the final authority and direct responsibility for the operation and safety of a flight under FAA Part 135 regulations. Even if the reported weather meets legal minimums, the PIC can and should refuse any flight they believe cannot be completed safely. This is a fundamental principle of aviation safety and demonstrates good judgment, not a violation or poor CRM.
