FS Calc

By Inquisitive Graphics, LLC

Open iTunes to buy and download apps.


FS Calc is a fuel planner for iPad or iPhone designed for users of advanced flight simulation add-on aircraft for Microsoft Flight Simulator. Mimicking an airliner CDU display, it quickly calculates precisely how much fuel you will need for your flight using the same style of interaction as the aircraft's CDU that you are used to.


Computes based on:
* Flight Distance
* Cost Index
* Cruise Altitude
* Zero Fuel Weight
* Winds

Other Features:

* Uses LBS or KGs

* Calculate alternate fuel by entering the distance to alternate

* Optionally FS Calc will automatically add 45 minutes to the fuel calculated to travel to your alternate airport

* Holding and Captains fuel based on minutes or weight

* On screen clock displays device time or UTC time

* Taxi Fuel calculated based on minutes or weight

* Download current airport weather information (TAF/METAR)

* Enter your departure, arrival and alternate airports and FS Calc will calculate the distances which you can transfer to your fuel calculation with a single button

FS Calc features the following aircraft as part of the base package:

737-700 Winglets
737-800 Winglets
737-900 Winglets

You can then purchase additional profiles for the following aircraft:

- MD-11 includes GE and PW engine variants
- B767-300 both winglet and non-winglet profiles
- B747-400 (works for all engine variants)

No complaints. Except the METAR section is literally a METAR I would prefer it broken down into lamen terms. Or closest to it as possible. I.E. wind direction and speed/gust, clouds, visibility and stuff like that. Precipitation/rate.

Maybe airport info too, like elevation and such.

Still a great app though!


It's useful but it doesn't have, u know, the same exact functioning as the real MCDUs in real aircrafts. It still needs more working by the developers, great over all

Looks fine

I compared it with real fuel planning system and it works fine with minor deviation. Thx
