I am watching all your videos and like them all and introduce them all to my friends! you are the best, Capt. Please make more and more videos. Cheers from our Iranian Pilot community
Thank you Captain! Your Channel need more promotion. I have two questions. 1) when do you use CI=0 ? What is the normal range for 738 for a Low Cost Airline? Do you have certain CI numbers which you can use during certain situations? For example when you are too late/delay/new slot time. Are you allowed to change during the flight the CI when you are ahead of schedule due to many shortcuts?
Hey, many thanks for watching the video, feel free to share it with your friends and colleagues or any social network. I have never used cost index 0, this CI value gives you the maximum range airspeed and minimum trip fuel, however, this doesn't mean that some operators don't use it. Zero Cost Index may be useful if you diverting, because, maybe, you are low on fuel so you want to burn the less possible. Some Low-cost Airlines uses Cost Indexes values between 6 to 30. But again, this can vary from one Airline to another substantially, and it depends on the specific flight and operations. When you are running late some Operators ask the Pilots to increase the CI value and fly faster to make up some time. Normally if you are ahead of the schedule you don't change the CI, if you can you want to fly your passengers to the destination early. I wish you a great day! PILOTCLIMB.com
@@PILOTCLIMB Thank you Gabriele for your answer, especially about CI=0 I learned new things today. I asked you about changing CI when you are ahead of schedule because in this video the CPT of a SAS Airlines A330-300 reduced the CI after getting shortcut, so that they fly slower to save fuel and to meet the arrival time on schedule. Check here at 08:00 th-cam.com/video/NAYowa4nmH0/w-d-xo.html P.S. I checked your website. It is very interesting. I am very thankful for your help! I am interested in aviation since i was a kid. I wanted to become an airline pilot when i was 11 and unfortunatly financially it was not possible. I thought myself a lot about aviation. I also studied a few years aeronautics at a university but had to interrupt because of financial reasons. So it is easy for me fortunatly to learn new things and to comprehend. Do you fly also in germany sometimes? I know which airline you fly for and i flew a few times from Weeze with your company.
Good Day Capt, in video stated lower CI mean fly with lower speed. Is it mean only with auto throttle/auto pilot on/engaged we fly follow the CI(Cost Index) that we enter in FMC in preflight?... Can we still fly with higher speed manually with autothrottle off(disengaged mode) even we input in preflight a lower CI ?
Hello cpt. Very good video as usual, thanks for your explanation. I've two questions : 1) If I'm flying with a very low cost index but I press max angle (shortest distance) or max rate of climb(shortest time) on the fmc will this override the Cost Index selected? 2) If I input a very high cost index, will the Mach speed increase during cruise? On my simulator (X-Plane 11.55 with the Zibo Mod) the typical crz spd is 0.75 Mach with a cost index of 30. A bonus question : If I'm flying very high and I'm really close to the coffin corner, will the speed decrease automatically even if I have a high cost index? Or the plane won't care? Thanks as usual, have a wonderful day
Hey, many thanks for watching!! So, the answer to the question n1 is Yes!... second question: that's correct.. higher cost index should give you an higher cruise speed...last question: The Aircraft has its overspeed protection, so the highest cost index (which is 500 on the B738) will give the high speed always below the VMO or MMO..
Good Day Capt,is it true that almost all budget airlines like Ryan Air,German Wings fly with lower cost index than state own airlines like Lufthansa,KLM,Airfrance,Alitalia ?
Good morning, many thanks for watching!! I don't know what cost index the flag carriers use, so I don't want to guess an answer that might not be correct. What I can tell you is that some airlines use variable cost index which changes depending on the sector, while others use a fixed cost index... Have a great day..
Good Day Capt,I have another question if let say we have one engine failure on flight and we want to land.Is it still ok to land with flaps 30/40 or we must choose other flaps setting ?
@@viktoriaelisabeth467 Good morning, very good question!! The procedure regarding landing configuration with one engine inoperative might change depending on the type of the aircraft. With 737 you should use Flaps 15 in case of an engine failure. However this might change a bit depending when the engine fails ( for example if it fails on short final and you have already flap 30 or 40 selected). I wish you a great day
@@PILOTCLIMB Good Day Capt,any technical reason behind this flaps 15 for B737 only 1 engine operative by landing Capt?is it to prevent a higher sink rate with B737...Have a nice weekend...Thanks again
