How to schedule 7 day week with cover when aircraft has B-check

I setup with 2xCRJ1000 (just purchased a CRJ200ER) and set both CRJ1000 to 4 destinations per day 7 days a week, using the 'tick for every day 7 days a week' option.  I then set my maintenance on a Sun and Mon for each individual plane except I then realized afterwards that when it comes to the B-check how will I cover each plane?

So my question is, when using that easy option of doing the schedule for 7 days, how can I alter it so that each of those 2 plane's can cover for each other?  Sorry if this sounds like I dumb question but I only joined yesterday and have read Gazz's tutorial but I still don't get it  :-\

Schedule over the B check - those routes will just not fly on the scheduled day for the B check - basically once every 4-5 weeks. The revenue drop is not much to worry about.

Also, for B checks, it's best to schedule them on the lowest demand days - Sat/Sun/Weds. Monday and Friday are the highest demand days...

So on the day of the B-check although you said they lost revenue will not be much, how will this affect my Route and Company rating?

B-checks will not affect your RI or CI at all. They are modeled in to the game. Same with C/D checks and configuration changes or hushkit upgrades, all forms of scheduled maintenance have no effect on your RI/CI (or your on-time percentage for that matter).

The only types of cancellations that affect those scores are unscheduled maintenance (plane goes tech at the gate during boarding), weather and traffic issues, and external events (visiting presidents, protests, fires etc). Passengers blame all that stuff on the airline. Just like in real life.

There are different schools on that topic. You can either target the low demand days, or target the low demand flights. Which I did in my tutorial, the B-Checks are spread around the week, stopping the worse destination once every 4 flights.

I must say I didn't do the maths, and your option might very well be better. It probably depends on the homogeneity of your destinations. I didn't have much LH destinations from ORY, and therefore I had to cumulate juicy destinations with scarce ones. the B check was always on the same scarce one. Of course, if you fly to similar-demand destinations, your school is probably better than mine.

Have you ever done the maths about that?

Because the if your B check doesn't coincide with the A check, the week in which the B check happen, you are going to paid the A check and the B check. That's doesn't happen if the B check and A check coincide as the B check includes the A check.

So it depends on the demand, offer and competition of yours routes.

I notice the system deducts from you 4 A-checks and 1 B-check montly per a/c, whether these checks coincide or not. I tell this because my A and B checks coincide in 99% of the cases but all expenses in line maintenance are equal to (4 A checks + 1 B check) / 4, no matter how you organize your maintenance schedules. The only benefit of coinciding A and B checks is that you'll be able to make 1 more flight per month.

Or the 3rd school of thought... target the HIGH demand fights! This sounds counter-intuitive but is actually logical when you think it through.  On a low demand route, I will have one weekly flight and I if I use that flight for the A check it only flies 6 days per week. OK... but I'm losing somewhere around 12% to 14% of the potential of that route. That's OK if I'm over-serving it anyway (100 seats, 60 demand for example).  What I actually try to do is schedule the A check to cover a very high demand route I fly at least 4 times weekly. That way I can have 4 A checks on the same route (Sat, Sun, Wed, Tue in that order of preference). The chances are that on such a high demand route there is a lot of competition anyway (typically 150% to 250% served) so it merely levels out my supply to almost exactly match the 'profile' of the demand curve and my 3 or 4 other flights the same day actually do a little better. I've not worked the actual numbers but I reckon the loss of potential is more like only 5% in this situation.

On once or twice daily routes, with the A checks nearly always falling on a Saturday or Sunday, allowing the B check at the same time means that the loss of a whole 24hrs at least also usually falls on Sat/Sun. Avoiding a late Sunday evening B check (protecting Monday morning flights) might be an advantage, but even I can't be bothered with that much micro-management!

I as speaking of destinations where you don't fly often. There are not many big destinations from WAW, you know.

Of course, when flying 20+ daily flights between Tokyo & Naha(12 000 demand in GW2), my practice does not work any more, and your is better.
