About this tool

Helicopter pilots planning IFR operations with Non-Part 97 Special Instrument Approach Procedures (SIAPs) face a common problem: the departure or destination facility often has no weather station on site. To build a picture of the conditions there, pilots must pull current weather (METAR) and forecasts (TAF) from nearby stations and weigh other sources as part of their planning.

The catch is elevation. When a reporting station sits significantly lower than the facility, the actual ceilings over the departure or destination can be lower than what the station reports — potentially below published minimums. Finding every facility and station elevation during planning and doing the math by hand is tedious and time-consuming. That's where helisiapp lite comes in.

helisiapp lite gives helicopter pilots fast, facility-specific estimates of ceiling and visibility, plus hazard awareness, for special instrument approach and departure planning — saving meaningful time during the planning process. Because most such facilities have no weather station on site, these figures are elevation-based estimates derived from the nearest reporting station — a planning aid, not a measured on-site observation, and no substitute for an approved weather briefing. They are meant to support your planning, not to determine approach minimums or make the go/no-go decision; those remain yours to make from official sources and your own judgment. While the primary app, helisiapp (not currently available), is an even more powerful planning tool, this free lite version tackles one of the major hurdles instrument helicopter pilots face.
