AltitudeAlert

Advanced Altitude Management for Pilots.
Integrated with a pilot designed flexible alerting system and VNAV (Vertical Navigation), AltitudeAlert is the first App to bring advanced altitude management to ALL pilots.
VNAV gives you unparalleled control of altitude. Use VNAV to define precisely HOW, WHEN and WHERE you want to be at a certain altitude. With customizable settings, you define how VNAV will work.
ALT HOLD Mode is specifically designed for VFR pilots requiring virtually no setup. Just tap the button and AltitudeAlert will monitor your current altitude. This mode is great for student pilots, formation flying, and pilots of vintage, ultralight, and light sport aircraft with minimal instrumentation.
Never miss an altitude assignment again. Set the altitude and AltitudeAlert alerts you prior to reaching it and again when you acquire it. Spoken alert announcements are customizable. Choose from a single chime or chime plus altitude remaining.
Need to shoot an approach? No problem! Set the minimums and AltitudeAlert will alert you 100' above minimums and again at minimums.**
**Barometric sensor required (see SYSTEM REQUIREMENTS below).
FEATURES:
• iPad version runs along side or in the background while using your favorite EFB App, i.e. Foreflight, Garmin Pilot, FlyQEFB, etc.

• Instrument Approach Minimums Alerting.**
**Barometric sensor required (see SYSTEM REQUIREMENTS below).
