RPC sUAS Loading and Performance 2

Question 1

A remote pilot adds a 0.5 lb camera payload to a sUAS originally configured for 0.3 lb. What is the most likely effect on flight performance?

Accepted Answer

Reduced flight endurance and slower climb rate

Answer

Increased maximum altitude ceiling

Answer

Improved stability due to lower center of gravity

Answer

No measurable effect if payload is under 1 lb

Question 2

Which condition would most significantly degrade sUAS hovering efficiency?

Accepted Answer

Operating at high density altitude with maximum payload

Answer

Flying over a paved surface

Answer

Using propellers rated for the manufacturer's recommended RPM

Answer

Flying in calm wind conditions at sea level

Question 3

An sUAS manufacturer specifies a maximum gross weight of 3.5 lbs. The airframe weighs 2.8 lbs with a fully charged battery. What is the maximum allowable payload?

Accepted Answer

0.7 lbs

Answer

0.3 lbs

Answer

0.5 lbs

Answer

1.0 lbs

Question 4

How does an off-center payload mounted to the front of a multirotor affect its flight characteristics?

Accepted Answer

The aircraft will tend to pitch nose-down and require corrective trim

Answer

The aircraft will gain speed due to forward weight shift

Answer

Flight time will increase because forward CG improves aerodynamics

Answer

There is no effect as flight controllers automatically compensate without limits

Question 5

In hot and humid summer conditions, a remote pilot should expect which performance change compared to standard conditions?

Accepted Answer

Reduced lift because high temperature and humidity lower effective air density

Answer

Increased lift due to denser moist air

Answer

No change since multirotor lift is independent of air density

Answer

Improved endurance due to reduced motor cooling requirements

Question 6

A remote pilot notices the sUAS is consuming battery power faster than normal during a standard hover. What is the most likely cause?

Accepted Answer

The payload weight exceeds the planned configuration

Answer

Wind is calm, reducing aerodynamic drag

Answer

The GPS signal is stronger than usual

Answer

The gimbal is locked in a downward position

Question 7

Which factor does NOT directly affect sUAS performance calculations for loading?

Accepted Answer

The color of the aircraft fuselage

Answer

Ambient temperature at the operating site

Answer

Total weight of the aircraft including payload

Answer

Density altitude at the operating location
