* Distance, Speed, and Time: Earhart would use these concepts to calculate flight times, fuel requirements, and potential arrival times.
* Navigation: Using maps and a sextant, Earhart could determine her location by measuring the angle of the sun or stars. This involved basic trigonometry to translate those angles into coordinates on a map.
* Fuel Calculations: She had to carefully calculate fuel consumption and ensure enough was available for the entire journey.
* Wind Correction: Earhart would factor in wind speed and direction to adjust her course and flight time. This involved simple vector addition and subtraction.
* Altitude and Pressure: Earhart needed to understand the relationship between altitude and air pressure to maintain safe flight levels and avoid dangerous weather conditions.
While she might not have been performing complex mathematical calculations, Earhart relied on her understanding of these basic math concepts for her successful flights. It was crucial for her to be able to quickly and accurately assess situations and make informed decisions based on her mathematical understanding.
