of visible moisture, it is imperative to note the OAT, particularly during climbs and descents, and
to avoid entering icing conditions.
Remember to subtract 15° from the Indicated OAT to determine a
more accurate OAT. Reference the PCL, to determine the actual
The probes anti-ice and windshield defogger are the only devices available to combat icing, and
are of limited value in removing ice. Use them when entering visible moisture before ice has a
chance to accumulate. Fly over, under, or around any known icing conditions when at all
possible. If ice has formed despite all precautions, land as soon as possible. Increase your
airspeed during the approach to maintain positive control of the aircraft. Consider a no flap
AIRCRAFT EMERGENCIES UNDER IFR
Although NATOPS provides procedural guidance in the event of specific emergency situations,
it does not provide precise guidance for all situations. The student must develop the ability to
recognize and analyze emergency situations and then determine a course of action to ensure the
safety of the crew and aircraft while considering specifics of the situation. Remember the golden
rule: "AVIATE, NAVIGATE, COMMUNICATE". If in holding or on an approach, continue
to perform your flying duties while executing the emergency procedures in a timely manner.
Determine the nature of the emergency and the urgency with which you should land, then devise
a plan and execute it. Notify ATC by declaring an emergency and advise them of your intended
action (requesting priority handling as necessary). The following factors will influence your
decision: weather conditions, fuel remaining, aircraft status and position, airfield proximity,
approach availability, and terrain. If lost, state your last known position, time, and heading since
In an emergency requiring immediate action, the IP may deviate from any rule or regulation as
necessary to the extent required to safely handle the emergency. If this emergency authority is
exercised and will result in a deviation from an ATC clearance, the IP must notify ATC as soon
as possible and obtain an amended clearance. Emergencies are generally classified under two
1. Distress: A condition of being threatened by serious and/or imminent danger and of
requiring immediate assistance.
2. Urgency: A condition of being concerned about safety and requiring timely but not
immediate assistance, although the potential for a distress situation exists.
