What is the decision height when flying a multi-engine aeroplane under IFR without any passengers on board?

• A. 30m (100ft)
• B. 60m (200ft)
• C. 75m (250ft)
• D. Above 100m

Answer: (A)

The correct decision height for a multi-engine airplane flying under Instrument Flight Rules (IFR) without any passengers on board is indeed 30 meters (100 feet). This specific altitude is significant because it reflects the regulatory standards that apply to flight operations under different conditions and with varying levels of safety assurance. Regulations typically mandate lower decision heights for multi-engine aircraft compared to single-engine planes due to their enhanced performance capabilities and redundancy systems. In the case of a multi-engine aircraft, the ability to maintain controlled flight with one engine inoperative allows pilots to execute approaches and landings safely even at lower altitudes. Therefore, the threshold of 30 meters represents the minimum height at which pilots must make a decision to continue their approach or execute a go-around, balancing pilot workload and safety considerations. Options that list higher decision heights like 60 meters (200 feet), 75 meters (250 feet), or above 100 meters, reflect scenarios that may apply to certain conditions or aircraft types but do not pertain to a multi-engine aircraft operating under these specific circumstances of IFR flight without passengers.
