News: I recommend the Boeing 737 Interactive System app by Eric Cannon.
It is actually 4 interactive systems in one: hydraulics, electrics, fuel, and bleed air.
All use the typical factory layouts, however I have been working with Eric on making my hydraulic diagram interactive. He has the first version released and ready for your critique. Abnormals will follow in a few weeks. But this first version is very good. And you can create some abnormals by
switch movement.
I hope to work with Eric in making my electrical diagram interactive.
The app is $25.00 Search for "B737 Interactive”.
I am looking for someone to take over publishing the Big Boeing FMC Guide.
If you are an active "Honeywell" (Big Boeing) pilot and want to get into writing, give it some thought.


I am pleased to announce I have teamed up with Robert Dorsett to produce the Cockpit Companion iPad app (CCIPAD). It includes several different models and airline configurations.

Note: CCIPAD requires iPad version 2 or later.

Using your iPad, do a search on the App store for B737. The Cockpit Companion CC's will display.

Touch the cockpit display to get to the Reviews tab.
