Crosswind component calculator
The sine rule, three rules of thumb, two worked examples, and how to relate the number to your aircraft's POH demonstrated crosswind.
Practical guides on the topics that come up around the Aero Companion tools — the crosswind component, glide distance, VFR planning, and flight diversion.
The sine rule, three rules of thumb, two worked examples, and how to relate the number to your aircraft's POH demonstrated crosswind.
Reading the classic crosswind chart at a glance — arcs, radials, and shortcuts that get you within a knot or two without arithmetic.
Weather, weight and balance, route and alternates, fuel, personal minimums, and a structured go/no-go decision for VFR cross-countries.
Glide ratio, the still-air glide ring, wind correction, and how to plan a cross-country that keeps a runway in glide range.
Why aviation uses UTC, how to convert between local and Zulu across DST, and how to read METAR/TAF/NOTAM timestamps.
Pre-decided diversion criteria, picking real alternates on the ground, and a clean in-flight decision flow when the plan stops matching reality.
