The following statements describe the procedure when a communication failure occurs while navigating under IFR. Which one is incorrect?

If an aircraft is in visual meteorological conditions, the aircraft shall continue to fly in visual meteorological conditions and land at the nearest airport etc. where a safe landing is considered possible.
If an aircraft is in instrument meteorological conditions, the aircraft shall proceed according to the last assigned route to the point over the destination (the airspace right above the destination aerodrome or the appropriate designated navigation aid/fix specified as a point which that an instrument approach procedure will be commenced if any).
If an aircraft is in instrument meteorological conditions, has arrived overhead the destination prior to failure of the communication equipment, has been instructed to wait overhead the applicable point, and has received the scheduled time for the commencement of approach, the aircraft shall wait overhead the applicable point until that time, and then commence descent.
Since direction signaling lights are used at an aerodrome where an instrument approach procedure is set, landing shall be performed according to light-based signals.

Which of the following statements regarding illusions during flight is incorrect?

The inclined ridgelines of clouds, obscured horizons, darkness containing a mixture of ground lights and starlight, and some types of geometric configurations of ground lights, for example, have a tendency to cause illusions whereby the attitude of the aircraft does not appear accurately aligned to the actual horizon.
In areas without ground objects, such as water surfaces, dark areas, or snow covered terrain, pilots have a tendency to fall under the illusion that they are flying lower than the actual altitude.
After staring at a static light in the darkness for several tens of seconds, pilots may fall under the illusion that the light is moving, whereby the pilot can be tricked by the apparent movement of the light and lose control of the aircraft.
Various complex motions encountered during flight and the appearance of external forces and scenery, etc., can cause illusions regarding motion and position. Vertigo caused by these illusions can be prevented by reliably and visually recognizing solid objects on the ground that can be trusted and flight instruments.
