Everything in the app
Weight and balance in seconds
Sliders for every station, both CG envelopes live on screen, then sign, save and email a PDF. Saved aircraft and configurations are one tap away.
In-flight screen
Relative wind, crosswind and head or tailwind components, pressure and density altitude, max HIGE and HOGE weight, power limits and Vne for current conditions.
Hover ceiling charts
Enter weight and temperature and read HIGE and HOGE limits straight off the POH chart for your type.
METARs and TAFs in two taps
Enter your ICAOs, hit send, and print. No accounts, no ads, no three websites.
Warning lights and MEL
What the POH says about every caution and warning light, and the MEL reference, without digging through the manual.
Offline converter
Every conversion a pilot needs preloaded, including GPS coordinate formats, and it works with no signal.
About Tool in the Cockpit
Tool in the Cockpit simplifies your preflight and in-flight routine. Not just to save time, but to make flying more focused, more enjoyable and more professional. It was built by a working commercial helicopter pilot for other pilots who love flying and love great tools.
As a working pilot you know how fast things change: extra luggage, a fuel top-up, a last-minute detour. The app lets you recalculate performance or weight and balance right there in the cockpit, without switching apps or flipping through paper.
Fuel is shown in kg, lb, litres, US gallons and percent all at once, so a weight and balance in pounds, a fuel gauge in gallons and a fuel truck in litres are no longer a problem. All other weights are in both lb and kg.
Free to download. R22 and AS350 are always free. Other types unlock with a free trial and a small annual subscription.
What pilots say
“By far one of the best apps I have used for helicopter planning, performance and limitations. I love that you can check the VNE limits for doors removed or open without having to check the manual on the H125. The flight section is brilliant, you have all your information at a glance.”
“Helping us tremendously, far superior to anything else on the market right now.”
“Having used many in-flight and planning helicopter apps, this one tops the list. From planning to in-flight data, I am amazed at how much information is available.”
“Great app for being free. It's worth a download, especially if you are new to flying. Using this for H125 commercial ops.”
“Great app. Does everything you need, including the option to email the W&B.”
“Great app for people that fly the AS350 and the RH series.”
“An excellent and a must have tool in your cockpit. Always comes in handy for relevant flight data at any time.”
“I use this daily. It is incredibly well designed.”
