General
Monitor the 10,000-ft, transition-altitude and pre-top-of-descent conditions separately. Use the assigned event schedule while retaining checklist item identity and document order. Do not defer an earlier transition-altitude event until the later 10,000-ft event. Verify STANDARD mode, its pressure setting and the required independent altimeter agreement. Before top of descent, make the required arrival-route modification and verify RNP for the arrival. Maintain the assigned continuous flight, navigation and fuel monitoring throughout climb and cruise.1. At or above 10,000 ft: Landing lights — Off
Condition: At or above 10,000 ft. When the stated condition is satisfied, select the applicable landing lights OFF. Verify the installed lights required by this item.Checks and evidence
Checks and evidence
When: At or above 10,000 ft.Expected response: OFFVerification: Verify the required lights are off using the correct reading shape and variant.
2. At or above 10,000 ft: Passenger sign — As needed
Condition: At or above 10,000 ft. Resolve the required seat-belt and no-smoking/chime selections from mission context and installed configuration.Checks and evidence
Checks and evidence
When: At or above 10,000 ft.Expected response: As neededVerification: Verify the actual requested signs/switch states.
3. At transition altitude: Altimeter — Set standard
Condition: At transition altitude. At transition altitude, set STANDARD. Verify the pressure-reference mode and indicated setting.Checks and evidence
Checks and evidence
When: At transition altitude.Expected response: Set STANDARDVerification: Confirm standard/local mode and each required side/standby cross-check.
4. At transition altitude: Altimeter crosscheck — Verify
Condition: At transition altitude. Perform an independent altimeter comparison with assigned tolerances.Checks and evidence
Checks and evidence
When: At transition altitude.Expected response: VerifyVerification: Compare the applicable captain/FO/standby values and reference modes.
5. Before top of descent: MOD route for arrival — As needed
Condition: Before top of descent. Prepare any required arrival-route modification from the approved arrival plan, review it on the CDU and execute only the intended change.Checks and evidence
Checks and evidence
When: Before top of descent.Expected response: As neededVerification: Confirm the intended route/arrival fields and absence of unintended modifications.
6. Before top of descent: RNP for arrival — Verify
Condition: Before top of descent. Verify the approach/arrival RNP requirement using mission data and displayed navigation-performance information.Checks and evidence
Checks and evidence
When: Before top of descent.Expected response: VerifyVerification: Require the applicable displayed RNP and navigation-performance evidence on the correct pages.
