Knowing how ISA works and how deviations from standard conditions impact performance is critical to safe and efficient flight planning, especially at high altitudes or in hot conditions. Conclusion The ISA model may be theoretical, but it plays a very real role in aircraft performance and flight planning. Hg (1,013.25

Flight at those speeds introduces all kinds of challenges, including the need to know your speed in relation to the speed of sound. Key Takeaways Mach number is a dimensionless ratio of true airspeed to local speed of sound. Mach number is simply a ratio of your true airspeed to the local speed of sound.

This is where the North Atlantic Organised Track System (NAT-OTS) guides your flight planning. Operational peculiarities The NAT-OTS is unique in the world, as it changes twice daily to provide optimum routes for the main traffic flows, with due regard to the winds and turbulence. The North Atlantic is a non-radar environment.

It is a particularly insidious phenomenon that can be a prime cause of turbulence. Can cause sudden losses or gains in indicated airspeed (IAS), directly affecting lift. DC = arctan(TAS/Vc) Where TAS is the True Airspeed. It’s a practical skill, especially for pre-flight planning and in-flight adjustments.
