How to effectively monitor and delete VNAV altitude constraints.
SCENARIO
WSSS - VENTU 1B SID - RW20C
1. FMA - THR REF | LNAV | VNAV SPD
2. After takeoff, Singapore Departure clears the aircraft to climb to FL240, no altitude restrictions
3. PF dials in 24000 on the MCP
What will happen? And what should be done instead?
