A remote pilot arrives at a job planning to fly a standard RGB camera payload but the client asks for thermal imagery instead. The thermal camera is 180 grams heavier than the RGB camera. The drone's published maximum takeoff weight is 2,100 grams; with the RGB setup it sits at 1,990 grams. What should the pilot verify before accepting the swap?

Question

Accepted Answer

That the new total remains under the MTOW, that the center of gravity remains within the approved envelope, and that flight time estimates are revised for the added mass. Maximum takeoff weight is only one limit. Payload position affects center of gravity; a thermal camera mounted at a different attachment point can shift CG even at legal total weight. Added mass also reduces flight time, affecting mission planning and battery margin. All three must be verified, not just the scale number.

Answer

Only that the total weight remains under the MTOW; thermal payloads are certified by the drone manufacturer

Answer

Nothing further is required; payload swaps are within the remote PIC's discretion without recalculation
