VASI. The approach and landings should be made in the same  manner as in day landings as discussed in Chapter 11,  Approaches and Landings. At night, the judgment of height,  speed, and sink rate is impaired by the scarcity of observable  objects in the landing area. The inexperienced pilot may have  a tendency to round out too high until attaining familiarity  with the proper height for the correct roundout. To aid  in night landings, approach with power on to reduce the  descent rate providing more time for the pilot to see the  runway and start the roundout once the runway is visible. To aid in determining the proper roundout point, continue  a constant approach descent until the landing lights refl ect  on the runway and tire marks on the runway can be clearly  seen. At this point, the roundout should be started smoothly  and the throttle gradually reduced to idle as the aircraft is  touching down.  [Figure 12-14]  During landings without the  use of landing lights, the roundout may be started when the  runway lights at the far end of the runway first appear to be  rising higher than the nose of the aircraft. This demands a  smooth and very timely roundout, and requires that the pilot  feel for the runway surface using power and pitch changes,  as necessary, for the aircraft to settle slowly to the runway.  Blackout landings should always be included in night pilot  training as an emergency procedure. Perhaps the pilot’s greatest concern about flying a single- engine aircraft at night is the possibility of a complete  engine failure and the subsequent emergency landing. This  is a legitimate concern, even though continuing fl ight into  adverse weather and poor pilot judgment account for most  serious accidents. If the engine fails at night, several important procedures and  considerations to keep in mind are:  Night Emergencies • Maintain positive control of the aircraft and establish  the best glide configuration and airspeed. Turn the  aircraft toward an airport or away from congested  areas. • Check to determine the cause of the engine malfunction,  such as the position of fuel shutoff, magneto switch, or  primer. If possible, the cause of the malfunction should  be corrected immediately and the engine restarted. • Announce the emergency situation to Air Traffi c  Control (ATC) or UNICOM. If already in radio  contact with a facility, do not change frequencies  unless instructed to change. 12-12
