UAS Lesson 00: Night Operations

How can the remote Pilot in Command and Visual Observer(s) avoid autokinesis?

• by staring at the sUAS for extended periods of time.

• by using proper night scanning techniques and using peripheral vision.

• by staying in the dark for 30 minutes.

The most effective method of scanning for other aircraft for collision avoidance during nighttime hours is to use

• a series of short, regularly spaced eye movements to search each 30-degree sector.

• peripheral vision by scanning small sectors and utilizing off-center viewing.

• regularly spaced concentration on the 3-, 9-, and 12-o'clock positions.

What is one of the requirements for flying an sUAS during twilight?

• the sUAS must be equipped with navigation lights

• the sUAS must be equipped with anti-collision lighting visible for at least 5 statute miles.

• the sUAS must be equipped with anti-collision lighting visible from at least 3 statute miles.

During a night flight, you observe a steady red light and a flashing red light ahead at what you estimate to be 300 feet AGL. What is the general direction of movement of the other aircraft?

• The other aircraft is crossing to the right.

• The other aircraft is approaching head-on.

• The other aircraft is crossing to the left.

Most midair collision accidents occur during

• cloudy nights.

• hazy days.

• clear days.

Can a sUAS be flown at night?

• Yes, as long as the rPIC received the proper training and the aircraft is properly equipped with anti-collision lighting that meet the requirements in 107.29.

• Yes, as long as the aircraft is equipped with anti-collision lighting.

• No, a sUAS can only be flown during the day and during twilight.

During a night flight, you observe steady red and green lights ahead at low altitude. What is the general direction of movement of the other aircraft?

• The other aircraft is flying away from you.

• The other aircraft is crossing to the left.

• The other aircraft is approaching head-on.

How can a military airport be identified at night?

• Alternate white and green light flashes.

• White flashing lights with steady green at the same location.

• Dual peaked (two quick) white flashes between green flashes.

During a night flight, you observe a steady white light and a flashing red light ahead at low altitude. What is the general direction of movement of the other aircraft?

• The other aircraft is crossing to the right.

• The other aircraft is flying away from you.

• The other aircraft is crossing to the left.

The best method to use when looking for other traffic at night is to

• look to the side of the object and scan rapidly.

• look to the side of the object and scan slowly.

• scan the visual field very rapidly.
