Corrective Action:
1. FLIGHT MECHANIC − REMAIN SECURED TO
AIRCRAFT
2. DO NOT USE EXCESSIVE FORCE
**INADVERTENT IMC
Possible Symptoms:
1. Unplanned entry into instrument meteorological
conditions (IMC) from visual meteorological conditions
(VMC) without proper ATC clearance.
2. Undesirable or unsafe aircraft attitude
1. CONTROL. Announce “IMC,” and fly the aircraft.
Both pilots shall refocus their scan inside the aircraft
and commit to the primary flight instruments – level
the wings, nose on the horizon, center the ball, adjust
power to maintain the desired flight profile and
airspeed. Engage FD modes as appropriate.
2. CLIMB OR MAINTAIN ALTITUDE. Depending on
the location of the IIMC encounter, maintaining
current altitude may be the best course of action.
However, if in the vicinity of rising terrain and/or
obstacles, climb to the appropriate altitude that
allows for terrain/obstacle clearance and radio
contact with air traffic control (ATC). Once
established in a stable climb, turn to the appropriate
heading to avoid rising terrain and/or obstacles.
3. COMMUNICATE. Attempt to contact ATC as soon
as the aircraft is stabilized in a climb and is headed
away from danger. If the appropriate frequency is not
known, attempt to contact ATC on VHF 121.5 or UHF
243.0. Initial information provided to ATC should be
approximate location that IIMC was encountered and
an emergency climb initiated, altitude, and amount of
flight time remaining (fuel state). Then request a
vector to either VMC or to the nearest airport/heliport
with environmental conditions that will support a
successful instrument approach. If unable to contact
ATC and a transponder code has not been previously
established with ATC for IIMC, change the
transponder to 77
