DESCENT
1. Defog Systems - AS REQUIRED.
a. Defog Fan - HI (at start of descent).
b. Cockpit Air Distribution - MAX.
c. Windshield Bleed Air Valves - MAX and Windshield Bleed Air Switch - LOW below 18,000 feet if landing temperature/dew point spread is less than 10°F/5°C.
2. Pressurization - SET DESTINATION PRESSURE ALTITUDE + 200 feet for landing.
3. Anti-Ice/Deice Systems - AS REQUIRED.
4. Throttles - AS REQUIRED; maintain sufficient power for anti-icing, engine anti-ice lights remain OFF above 70% N2 (minimum).
NOTE
•
At higher altitudes and lower outside temperatures, higher N2 (73 - 78%) may be required to keep the annunciators extinguished and to operate the tail deice boots if all anti-ice systems are operating.
5. Altimeters - SET at transition altitude and CROSSCHECK.
6. Landing Data (VAPP, VREF, N1, Landing Distance, Weight, and Factors) - CONFIRM.
7. Landing or Recognition Lights - AS REQUIRED.
•
Bulb life is extended considerably by using the recognition/taxi light position.
