737 VNAV Level Off during Descent
Guys, today I had the pleasure of jumpseating in a company 737.
I witnessed something during the descent which confused me slightly. I didn't want to ask the guys as they were very busy and sterile cockpit etc.
They were told to descend FL240 level at KRISE.
They had KRISE /FL240 in the FMC.
Shortly later they were told to descend FL190.
As soon as they reached KRISE, the aircraft levelled off at FL240 and I caught this new green TOD appear on the ND. They realized they levelled and went V/S.
This sort of caught them by surprise and even myself.
Surely after KRISE, where the a/c had reached it's altitude restriction, and with 190 in the MCP ALT, the a/c ahould have continued it's descent?
