Q

Anti Ice / Rain Note

A

Do not rely on airframe visual icing cues or advisory ice detector, if installed, to turn engine anti-ice on.

Use temperature and visual moisture criteria specified in this section.

Delaying the use of engine anti-ice until ice build up is visible from the cockpit may result in severe engine damage and/or flameout.

Q

B767 Operation in Ice Crystal Icing Conditions

A

Engine anti-ice ON when ice crystal icing conditions exist, even when temp is below -40C OAT.

The advisory ice detector does not respond to ice crystals.

Do not use anti-ice if OAT or TAT exceeds 10C (50F).

B767 Operation in Ice Crystal Icing Conditions - NOTE 1
Ice crystal conditions exist when in visible moisture and one or more of the following indications are present. - Amber or red weather radar returns below the aircraft. - Appearance of liquid water on the windshield at temperatures too cold for rain (sound is different than rain). - Autothrottle is unable to maintain the selected airspeed. - TAT indication on EICAS stays near 0C
26
B767 Operation in Ice Crystal Icing Conditions - NOTE 2
Erroneous TAT indication--lasting from one minute to more than 20 mins--may occur as a result of ice crystals blocking the sensor. TAT normally should increase approximately 2C / 1,000' or descent. When conditions no longer exist, use engine anti-ice normally.
27
Autoland flap limitations
Flaps 25 or 30
28
Minimum A/P engagement on takeoff
200' AGL or above
29
Aileron trim with A/P engaged?
No
30

Do not use below 100' radio altitude
31

Headwind - 25 KTS Crosswind - 25 KTS Tailwind - 10 KTS
32
ACARS transmission and receipt limitations
Messages which will not create an unsafe condition if the message is improperly received, such as: - Message or parts are delayed or not received - Message is delivered to wrong participant - Message content may be frequently corrupted
33
Approved ACARS transmissions
Pre-Departure, Digital Automatic Terminal Information Service, Oceanic Clearances, W&B, T/O Data if they are verified per approved operational procedures.
34
ADSB Automatically transmits when..
Transponder is active (not OFF or in STANDBY)
35
Transponder Fail Light
Represents a loss of GPS inputs for ADS-B position to the selected transponder. May result in the ATC Fault EICAS Message (as installed). If TCAS remains operational, the fault light would indicate GPS input not valid.
36
Extended Squitter Transmission Limitations - 1
B767 and B757 system does not take into account system's uncompensated latency into its transmitted horizontal quality indicator value.
37
Extended Squitter Transmission Limitations - 2
Some B767 systems do not have capability to transmit 7500, 7600, and 7700. Instead, transmits generic emergency indicator when any emergency code is selected on ATC control panel.
38
Extended Squitter Transmission Limitations - 3
Only B757 A/C equipped with dual GPS ADS-B Out have demonstrated proper operation (except for horizontal quality)
39
Emergencies in ADS-B only environments (non-radar)
Voice communication with ATC is required to positively report nature of emergency. The ADS-B emergency signal may not differentiate which emergency code has been set.
