What is the maximum rate of climb for a weight of 4,000 lb at a pressure altitude of 5,000 ft and temperature of 30°C?

To determine the maximum rate of climb for an aircraft at a specific weight, pressure altitude, and temperature, we can utilize performance charts or equations pertinent to the aircraft being evaluated.

First, it is important to recognize that the maximum rate of climb is influenced by several factors, including the aircraft's weight, altitude, and temperature. At a pressure altitude of 5,000 feet, the air density decreases compared to sea level, which affects the aircraft's performance. Higher temperatures also contribute to decreased air density, impacting thrust and lift.

With the given weight of 4,000 lb, the maximum rate of climb can be more precisely calculated using methods like the "rate-of-climb formula" or referring to the specific aircraft’s performance chart that considers the conditions of altitude and temperature.

The option identified as the correct answer, which is 702 ft/min, aligns with the expected climb performance for the specified conditions. In calculating this, one might consider the power available versus power required, adjusting for the effect of weight and environmental conditions.

Since the temperature of 30°C is relatively high for a standard atmosphere at that altitude, the expected climb performance will be reduced compared to standard conditions. This is reflected in the achieved maximum rate of climb being
