737-800 Iphone App

Searching in the Apple Store I found this App, very interesting called: '737-800 Performance Calculations'. No more smoky brakes this summer! By the way I have nothing to do with this app owner. Happy landings!

I would be very wary of using something that is not officially approved for something as important as landing performance :=

You're airline must have provided you with the means to calculate landing distance :confused:

The only use I could see for this is using it as rough guide for seeing which turn off you will make in non limiting situations

You are right! I agree this is not for 'official use', but if you are a 737NG driver you must agree that the brake cooling checklist is the most 'difficult' checklist as it needs lot´s of interpolation, is nice to crosscheck the amount of error a pilot can make with the checklist interpolating always on the safe side. Happy landings!

Yes sooooo difficult checklist.:eek:
Hint:you can also interpolate on the safe/worse side too:8

Well....... if like hundreds of airlines you are using the FCOM advisory information for performance inflight, you must agree the 'recommended brake cooling schedule' is a complex checklist to get acurate result. I give you an example: LW 58000 tones, OAT 33º, KIAS 135, Pressure altitude 1200 FT........ with this values first you interpolate between the value of 60 tones and 50 tones, then the temperature betwwen 30º and 40º, same for speed between 120 and 140 KIAS, then pressure altitude between 0 and 5000 FT........So what happens in real life is that we are busy enough preparing the approach, dealing with ATC and so on that you are not going to start using you calculator for 10 minutes to get exact values......so we round it up to the safe side and that´s it. That´s why I think this app is nice once you have round it up with you operator checklist to be 100% you are on the safe side, to actually see the amount of difference with the actual we are going to have. Happy landings!

Cannot find the app in appstore.

It is available under this link (https://itunes.apple.com/de/app/737-800-performance-calculations/id657364630?mt=8), but it may not be available in you country or the app store variant there as there are quite a few regional differences.

Not affiliated with the developer in any way and i haven't bought it yet, dunno if i ever will as it has some shortcomings.

So far I´ve been crosschecking this App in the plane with the QRH Performance inflight checklist boeing provide my airline, and with calculator in hand the calculations for me are all correct. If I could change something on this app I would make the selection buttons slightly bigger and with a stronger color on the selected option, but anyways for me is a really nice App, so let us know when you finish yours, looking forward to see your app and compare!
