As described in the Mentour Pilot video, LEAP-1B engines have an issue in which bird strike events that result in fan blade damage can lead to engine oil entering the bleed air system. On the 737 MAX, the left engine bleed air primarily supplies the cockpit while the right engine bleed air primarily supplies the cabin. The automated logic in the engine only shuts down the bleed air valve if the engine N2 drops below a certain threshold. This means that in a left engine bird strike event, the cockpit can quickly fill with smoke, which may only stop once the pilot pulls the engine fire handle. The fire handle can’t be pulled right away because safety checklists must be followed to avoid shutting down the incorrect engine. In addition, pilots are unable to complete checklists right after takeoff when very close to the ground due to the high workload. Although a software fix may be underway, the issue can also be prevented (prior to any bird strike) by turning off the number 1 air conditioning pack prior to takeoff. In the Mentour Pilot video, Petter advocates for this change to 737 MAX procedures as a stopgap solution to the issue. The solution wouldn’t be perfect since bird strikes can still occur in other phases of flight. However, the pack could also be disabled when close to landing.
It's unfortunate that he uses such clickbait-y headlines and thumbnails because the content on that channel is excellent.
well he's trying to run a business, has a full staff, he needs views! If he titled that video something drab and boring with no good thumbnail who is that helping?
To be fair to him, it was probably one of those that caused me to find the channel in the first place.
