This is the continuation of Air-Ground Sensor Failure in Kabul - Part 1. This video starts with NNC completed, except for the landing checklist. Coordination with the ATC about the intentions and all the briefings are already completed.
Hi Captain. Fantastic effort. Very helpful. Just quick ques. 1. If maintaining 10,000', why pressurise and bring the cabin to 8,000' when un-pressurised is safe for the entire manoeuvre to follow. 2. Why 'no engine bleed' setup prior to visual landing? 3. Will LVL CHG mode work?
Hi Navneet, thank you very much for the feedback. You brought some very good points: 1) There is no need to pressurize the cabin if your intention is to keep the flight not above 10,000 feet. Pressurizing the aircraft and bring the cabin to 8,000 just bring some more confort to the crew and pax, avoid the anoying cabin altitude warning that may sound if the cabin climb just above 10,000, and finally, it was a demonstration of how to deal with the pressurization manual control. In case it is not VMC, it will be necessary to climb above 10,000 feet to start the ILS or RNAV approach. It may also be necessary to climb if you need to divert. In these cases it would be necessary to use the manual mode control. 2) The no engine bleed landing would provide some extra thrust in the unlikely event of a single engine go-around. The APU is already running, the aircraft is heavy, so why not? It was also a good chance to demonstrate on the video how easy it is to perform this procedure. 3) I think LVL CHG is also available. I will confirm thid information on the first opportunity. Just have in mind that if you engage it after takeoff with takeoff power selected, the aircraft very soon will reach 10,000 feet. I also like to highlight that eventually there is more than one may to deal with a given situation. It is up to each one of us to find the solution that better fits our needs, according to the experience and knowledge that we have. Safety is always the number one priority, but I also consider a lot the workload management.
Thanks a lot for the detailed response. Much appreciated. Got your point of demonstrating the capability in the same video. Also regarding point 2, the anticipated engine failure on approach, thus no engine bleed. We can also take the gear up by override if that happens, I guess. Well keep more of these videos coming. Strength to you.
