Average ISA Deviation vs AeroNOTAM

Average ISA Deviation is a fast and precise utility designed for pro pilots who need to calculate the average ISA temperature deviation to correctly enter the DES FORECAST in the FMC of the Boeing 737 (NG / MAX) and other aircraft. The app allows you to: • Quickly calculate the average ISA deviation • Reduce workload and potential errors during descent planning • Simplify calculations that are normally done manually • Work fully offline, ideal for cockpit use Designed by a pilot, for pilots.

It does not replace official aeronautical charts, flight planning systems, company procedures, or regulatory guidance.

AeroNOTAM gives you easy and fast access to NOTAMs worldwide. It features offline data-management, multiple list views, map view, notifications, and filters. You can bookmark NOTAMs for later reference and share them by mail, message, or social media sites. NOTAMs are organized as routes either by flightpath (arrival/departure airport), an airport with radius, a simple list of your most used airports, or by swiping on the map and defining a radius. Appropriate FIRs will be added automatically. Optionally airport NOTAMs can be shown in local time. AeroNOTAM supports also background refresh, which (when enabled) fetches new NOTAMs automatically in background. You can define alerts (push notifications) for airports and FIRs to be notified (between 1 and 48) hours in advance before a NOTAM becomes effective. Data access after 14-days free trial period is available thru (non auto-renewable) 2-months subscriptions. Data is provided by US FAA which covers a lot of airports, however, they might not provide data for smaller airfields or local NOTAM series outside the US. Please note: AeroNOTAM will be shut down in 2026 and most functionality will be integrated into AeroWeather Pro.
