At -17 °C temperature and 2,300 RPM at 6,000 ft, what is the maximum flight time available?

To determine the maximum flight time available at a specific temperature, RPM, and altitude, it’s crucial to reference the performance charts or tables relevant to the specific aircraft in question. In this scenario, at -17 °C temperature, 2,300 RPM, and an altitude of 6,000 ft, we look at the fuel consumption rates and efficiency at these operating conditions.

At the given temperature and RPM, fuel efficiency tends to be optimized, which directly affects the total maximum flight time achievable before fuel depletion. Typically, lower temperatures can enhance engine performance, resulting in a more efficient fuel burn rate which lengthens potential flight duration.

In this case, the response indicates that the maximum flight time available is 4 hours and 30 minutes. This timeframe suggests that under the operating conditions provided, the aircraft's fuel capacity and efficiency were calculated to support flight spanning that specific duration. Flight time is usually assessed based on fuel flow rates which can be derived from the engine's power settings (RPM) and atmospheric conditions, confirming how long the aircraft can maintain flight before needing to refuel or land.

The other options suggest longer durations, which may not align with the calculated performance metrics for the parameters specified. Factors such as changed fuel burn rates at different RPM
