1. GENERAL
User: itastamb - Printed By myTechCare - Jul 28/23 - 09:13:10
For the sake of accountability, first editions of the Flight Operations
Letters (FOL) are sequentially numbered on a yearly basis. The Flight
Operations Letter revisions carry both the first edition and the revision
dates, and the original number remains the same.
The FOL STATUS column in the FLIGHT OPERATIONS LETTERS
RECORD sheets is intended to be filled in with the conditions stated
below as applicable:
IN EFFECT
It means that the FOL contains current and pertinent information, which
is not otherwise covered in other operational publication or was revised
to update its content.
INCORPORATED
It means that appropriate information has been incorporated in the
pertinent publications, and the FOL may be disregarded.
CANCELLED
It means that the FOL is no longer in effect and should be disregarded.
The FLIGHT OPERATIONS LETTERS INDEX sheets present the titles
of the FOLs published by Embraer from 2010 up to the date of this
issuing.
The FLIGHT OPERATIONS LETTERS SUBJECT INDEX summarizes
all the documents according to the subject that the letter is related to.
For your easier control, complete the FLIGHT OPERATIONS LETTERS
RECORD and the FLIGHT OPERATIONS LETTERS INDEX sheets
upon receipt the Flight Operations Letters.

Revision 1 - Mar 16, 2018
SUBJECT: MOMENTARY LOSS OF FLIGHT DIRECTOR
INDICATION ON ONE PFD WHEN CHANGING FLIGHT LEVEL
APPLICABILITY: Legacy and EMB135/145 shuttle fleet with
IC-600 phase 12 or phase 12.5 Installed.
User: itastamb - Printed By myTechCare - Jul 28/23 - 09:13:10
DESCRIPTION
Embraer has identified that under certain circumstances, momentary
loss of flight director (FD) indication on the slave PFD may occur
during flight.
Whenever the autopilot switches to the altitude preselected mode
(ASEL), a loss of the FD indication may occur on the PFD that is not
coupled to the AP (slave), for a short period of time. The indication
loss is momentary and is displayed back again when the altitude hold
mode is engaged.
The ASEL mode is a transitory mode used by the autopilot to change
from a flight level change mode (Pitch hold, Speed hold, vertical speed
or flight level change) to the altitude hold mode.
RECOMMENDATION
SOP-135/1664 - Section 5-40 already has the recommendation of
maintaining the autopilot source always selected to the side of the pilot
flying (PF). By doing so, PF will not experience the behavior described
in this document.
This glitch will be addressed on the IC-600 Phase 13 software to be
released 4Q13.

SB 145LEG-34-0032 or factory-incorporated.
User: itastamb - Printed By myTechCare - Jul 28/23 - 09:13:10
DESCRIPTION
The purpose of this document is to inform that in accordance with
current regulations, all EASA Operators, all ANAC Operators and all
FAA Operators (except Part 91), with FMS 6.1 installed must be
trained on the “Differences between L600 and L650” module to
operate all the components of the new FMS 6.1 (RNP 0.3, BaroVertical Navigation, Charts & Maps, and as optional, LPV/WAAS and
FANS 1/A), which will enhance pilot situational awareness, reduce
pilot workload, improve access to airports with high traffic, reduce flight
time due to optimized routing among other benefits.
Although the new avionics package for the Legacy 600/650 and EMB
145 XR has been granted installation/airworthiness approval, the
installation itself does not constitute operational approval as stated in
the applicable AFM.
RECOMMENDATION
In order to safely explore all the benefits of this avionics upgrade for
the Legacy 600/650 and EMB145 XR, Embraer advises that this is a
theoretical and practical training at Flight Safety International (FSI),
where pilots will be prepared to handle different types of scenarios and
situations, and will learn how to take the best advantage of this
package.
L650 Operators: The FANS 1/A, Charts & Maps, RAAS, RNP 0.3,
LPV and VNAV functionalities are already included in the initial and in
the recurrent training, which have theoretical and simulator sessions.
L600 and ERJ 145 XR with FMS 6.1 (FMZ2010) avionics: The
operator must request that Flight Safety includes the “Differences
between L600 and L650” module to the initial or recurrent training
session.

The INCR/DECRT toggle switch is left at the INCR position, the fuel
quantity selection displayed on the repeater will increase progressively
until it reaches 24500 lb.
Whenever the selected fuel quantity exceeds 24200 lb, the FCU will
not start the refueling, unless the overfill selection is reduced.
User: itastamb - Printed By myTechCare - Jul 28/23 - 09:13:10
Embraer emphasizes that the selected amount of fuel to be uplifted
shall be equal to or less than 24200 lb.
In order to prevent an overfill selection, the INCR/DECRT toggle
switch should be pressed in accordance with AMM II 12-11-01-3 and
AOM 1-12-25, until the fuel quantity displayed on the repeater is equal
to or less than 24200 lb.
NOTE: The maximum selectable fuel quantity shown on the
refuel servicing panel (24500 lb) and the maximum
selectable fuel quantity to initiate the refueling process
(24200 lb), do not reflect the maximum fuel tanks
capacity, which will usually be less than the mentioned
values, due to fuel density variation. For the exact
value of maximum fuel tanks capacity, please refer to

SUBJECT: ACARS MANUAL ENTRY OF DEPARTURE AND

APPLICABILITY: Legacy fleet equipped with FMZ 2010 (FMS
6.1)
DESCRIPTION
User: itastamb - Printed By myTechCare - Jul 28/23 - 09:13:10
The Honeywell FMZ 2010 (FMS 6.1) no longer sends the active flight
plan departure and destination information automatically to the CMU.
As a result, the aircraft will not send the origin and destination to the
ACARS.
A major function of ACARS is to automatically detect and report
changes to the major flight phases (Out of the gate, Off the ground, On
the ground, and Into the gate), referred to in the industry as OOOI
reports. These OOOI events are detected using input from aircraft
sensors such as doors; parking brake and strut switch sensors. At the
start of each flight phase, an ACARS message is transmitted to the
ground describing the flight phase, the time at which it occurred, and
other related information, such as the amount of fuel on board or the
flight origin and destination. These messages are used to track the
status of the aircraft. The solution for this behavior is to be
implemented in the next FMS revision.
RECOMMENDATION
Embraer recommends inserting manually the departure
destination information before each flight, by following the steps:

SUBJECT: MANUALLY TRANSITIONING THE DATALINK
SOURCE OF COMMUNICATION FROM VHF TO SATCOM
APPLICABILITY: Legacy fleet post-mod 145LEG-23-0040
(FANS 1/A Installation)
User: itastamb - Printed By myTechCare - Jul 28/23 - 09:13:10
DESCRIPTION
Embraer has received some reports from customers that are using
datalink on aircraft equipped with FANS 1/A of the system not
automatically transitioning from VHF to SATCOM.
FANS 1/A is an avionics protocol which provides direct data link
communication between the flight crew and the air traffic facilities.
These communications include controller/pilot communications and
position reporting.
Primarily the system uses the VHF data radio, typically VHF #3, to
exchange information between the aircraft and the ground stations.
VHF was selected as the primary source of communication because it
is typically able to exchange data at higher speeds.
When flying over remote areas, including oceanic airspace, where the
ground stations are not available, the system automatically changes
the communication source to SATCOM. By using this link, the data is
sent through satellites to the ground stations.
The FANS 1/A is an optional feature for aircraft that are using the
Honeywell FMZ 2010 (FMS 6.1) and may be installed through the
Service Bulletin 145LEG-23-0040.
The permanent solution for this condition is being investigated by the
engineering personnel.
Until a final solution is implemented, EMBRAER recommends
changing the VHF #3 mode from DATA to VOICE in order to force the
system to exchange data through the SATCOM exclusively.
For SATCOM DIRECT customers, this procedure will not affect the
DATA transmittal costs, as the DATALINK uses a different channel of
the onboard internet, and the DATALINK through satellite is provided
on an unlimited bases for aircraft appropriately subscribed.

Revision 4 – Sep 30, 2019
SUBJECT: FMS NAV DB ID
APPLICABILITY: All Legacy 600/650 fleet with Honeywell FMS.
DESCRIPTION
User: itastamb - Printed By myTechCare - Jul 28/23 - 09:13:10
Embraer has received many reports from customers regarding missing
procedures in the FMS. The main cause of this issue is the incorrect
installation of NavDB on the FMS.
This letter intends to help the operator identify the correct NavDB to be
installed in a particular version of FMS hardware and software.
RECOMMENDATION
The FMS retrieves information from the navigation database about
waypoints and procedures used for flight planning and to tune
NAVAIDS for position determination. The database, supplied by
Honeywell, is updated every 28 days.
The navigation database is designated with a version number, region
name, and cycle number (e.g., Version 3.01, WORLD3--310). The
FMS uses a Version 3.01 navigation database or other approved
version numbers. The region name (e.g., WORLD 3, NZ3EAST,
NZ3WEST) varies depending on the content of the navigation
database.
The last two digits indicate the cycle number (e.g., --310). There are
13 cycles (28--day periods) during the year. Therefore, the last two
digits range from 01 to 13. When a cycle is modified off cycle, a letter
is appended, starting with letter A. For example, WORLD3--310A
indicates a modified 10th cycle of the navigation database.
NOTE: It is recommended to verify Honeywell database

DESCRIPTION
Honeywell repair facilities have identified that for some random access
memory (RAM) problems it is possible to restore all the FMS functions
with a hyperstart procedure. The hyperstart procedure resets the RAM
to the initial values. In some cases, this will clear what appears to be a
hardware failure and prevent the unnecessary removal of the NZ2010.
The common issues observed by operators regarding RAM problems
are CDU freezing, FMS drops to single operation and spurious

Embraer recommends that the operator proceed with the Hyperstart
procedure after a new NAV DB cycle has been installed into the FMS.
The airplane shall be on ground and energized.

SUBJECT: ICE CRYSTAL ICING
APPLICABILITY: All Legacy 600/650 fleet
User: itastamb - Printed By myTechCare - Jul 28/23 - 09:13:10
DESCRIPTION
In the aviation industry, “icing conditions” is a well-known and
documented phenomenon. It occurs with the presence of liquid water
droplets in temperatures lower than freezing point. Such environment
conditions can cause ice to adhere to the cold airframe. However,
there is another phenomenon known as “ice crystal icing”, which is
less common and harder to detect using radar returns.
The conditions that have shown high concentration of ice crystals are
found almost exclusively near deep convective clouds, thus, the
potential to cause substantial effects in airplane airframe and systems
is higher.
Large convective formations have the capacity to lift high
concentrations of moisture to high altitudes. When this moisture
reaches low ambient temperatures, it freezes and turns into ice
crystals.
A result of this phenomenon is that the ice crystals, although in large
concentration around the deep convective storm, are small in size. The
onboard weather radar provides good awareness for rain, hail, and
snow. When flying into ice crystals (even in high concentration), the
radar only provides little or no reflectivity due to their size.
The most probable location of high concentrations of ice crystals is
downwind of the storm (anvil of the cloud) or above the red radar
returns. Such locations are depicted in Figure 1.

Figure 1- High concentration of small ice crystals are expected:
(1) above the red radar returns and (2)(3) downwind of the storm
in the anvil of the cloud.
RECOMMENDATION
The phenomenon of ice crystal icing occurs with high concentration of
ice crystals in the atmosphere. This phenomenon is associated to
several in-flight events, from different airplane models and
manufacturers. Most of the reported events happened in temperatures
above ISA (International Standard Atmosphere), in a range between
ISA+10°C and ISA+20 °C. All the events occurred near deep
convective clouds.
A set of characteristics and observations from those confirmed events
that may help identify an area of high concentration of ice crystals
include:
−
Flying under IMC conditions (Instrumental Meteorological
Conditions) and near (laterally or vertically) to a thunderstorm
cloud,
−
Only light to moderate turbulence,

−
Absence or light radar returns (scattered green reflections) at
flight level,
−
Air data anomaly: A high concentration of ice crystals can
reduce thermal capacity for heated instruments. In this case,
ice can start to accumulate on external sensors such as pitot
tubes and TAT probes. In these cases, unreliable airspeed
and wrong measurements of the total air temperature may
occur,
−
Reports of rain at temperatures where liquid water could not
exist. It was found that the rain is the result of large
concentration of small ice crystals melting in contact with the
heated windshield,
−
Non-significant airframe icing: When flying under ice crystal
conditions, the ice crystals bounce at the airframe and do not
accumulate in the cold parts of the airplane.
The procedures "In Flight Operations" for "Lightning Strike" published
on block 2-77 in the Standard Operating Procedures (SOP) are also
applicable to avoid high concentration of ice crystals:
Thundercloud Detected...............CIRCUMNAVIGATE.................PF
Circumnavigate the detected thundercloud or area by 25 miles
or more when traffic conditions permit.
To anticipate areas of higher ice crystal concentration, observe wind
direction.
When circumnavigating a thunderstorm, use radar tilt function and also
evaluate radar returns below the airplane. Areas directly above red
returns might also contain high concentration of ice crystals.
Therefore, avoid flying over such formations.

where connection attempts were performed without success, both
flying at the same region and/or route.
Honeywell and Embraer have investigated the root cause of the
reports and why the Legacy Fleet equipped with the MKIII CMU and
NZ6.1 FMS were sometimes unable to log into ATC for FANS use.
In the reported scenario, the FMS CDU displayed “SENT" but a
“Logon Accepted/Rejected” message was never received.
After investigation, as per the SIL - D201901000044 and SIA 000014513, Honeywell found the APM parameters listed as index 61
"Monitor FMC 1" and index 63 "Monitor FMC 2" to be incorrectly set to
NO.
RECOMMENDATION
The AMM II - APM Settings (AMM II - 23-24-03) was recently revised
to list the parameters below that shall be set to “YES”.

FOL LEG-002/22
DATE: May 05, 2022

SUBJECT: USE OF SUSTAINABLE AVIATION FUEL (SAF)
APPLICABILITY: Legacy 600/650 fleet
User: itastamb - Printed By myTechCare - Jul 28/23 - 09:13:10
DESCRIPTION
Sustainable Aviation Fuel (SAF) is produced from sustainable
feedstocks and is similar in its chemistry to traditional fossil jet fuel. Use
of SAF has been increasing recently and results in reduced carbon
emissions compared to traditional jet fuel over the fuel lifecycle.
Operators have raised questions about the usage of SAF, as some
airports and fuel suppliers are offering jet fuels made from synthetic
blending. According to the FAA SAIB NE-11-56R4, synthetic kerosene
produced under ASTM International Standard D7566 can be used when
blended with fossil-based Jet A/A-1, up to the percentage limits stated
in the same standard.
Thus, once observed those limits, the final blend can be re-identified as
D1655 fuel and therefore meets the approved operating limitations for
aircraft and engines certificated to operate with D1655 fuels, with no
need for any additional approval or authorization.
RECOMMENDATION
SAF D7566 jet fuels, re-identified as D1655-JET A or JET A-1, shall be
considered as ASTM D1655 fuels, which are approved.

FLIGHT DIRECTOR
APPLICABILITY: EMB-135BJ AIRPLANES POST-MOD.
SB145-31-0029 OR POST-MOD. SB145-31-0027 REV.02 AND
ON.
User: itastamb - Printed By myTechCare - Jul 28/23 - 09:13:10
DESCRIPTION
Some operators reported that after upgrading to phase 17 (Version 27)
software, there is a flight director issue when coupled to the right side.
The issue is reported to occur in the following scenario:
a) Autopilot coupled to the RH flight director (IC-600 #2).
b) Aircraft climbing in VS mode, and a target flight level selected (ASEL).
c) When approaching the target flight level, vertical speed decreases as
expected, and ALT mode becomes active.
d) With the target Flight Level reached, the aircraft continues to climb at
approximately 50 ft/min and continues to do so (exceeding 300 ft above
the selected/active flight level).
The issue has not been duplicated on a Honeywell bench and is under
investigation.
RECOMMENDATION
Flight crews should be aware of this flight director issue as currently,
there is no operational workaround to prevent the scenario. If you face
such an event, please report it to Embraer Services & Support.
