A remote pilot is hired for a real estate shoot. The drone's spec sheet shows 28-minute flight time. The mission plan is 22 minutes. On the day of the shoot, it's 96°F and the pilot has mounted a camera gimbal bringing the drone to maximum rated payload. What is the most accurate assessment?

Why →
Spec sheet flight times are measured under ideal conditions: standard temperature (around 70°F), no payload, no wind. At 96°F and maximum payload, actual flight time may be 20–35% shorter than spec. Potentially bringing a 28-minute drone down to 18–22 minutes. That eliminates the entire safety buffer for a 22-minute mission. Heat reduces battery efficiency and increases motor workload; maximum payload adds motor load further. Planning against spec times in non-ideal conditions is one of the most common real-world performance errors.
The trap →
The 6-minute buffer sounds reassuring, but it's calculated against a spec time that doesn't apply in hot, heavy conditions. Option C describes a monitoring tactic that is good practice but doesn't address the root problem: the plan was built on an unrealistic baseline.
