http://www.braeunig.us/space/propuls.htm The most common unit for specific impulse is the second, as values are identical regardless of whether the calculations are done in SI, imperial, or customary units. Nearly all manufacturers quote their engine performance in seconds, and the unit is also useful for specifying aircraft engine performance. The use of metres per second to specify effective exhaust velocity is also reas…

WebRunway elevation: Higher places have less dense air, so more speed is needed to get airborne, and less thrust is available from the engines than at sea level. Runway slope. Taking off downhill is equivalent to having a little extra thrust. Air temperature: Colder air is denser, so minimum speed is lower and the engines develop more thrust. WebJul 2, 2024 · Things to Notice. Air pressure drops rather quickly near sea level. After ~30 km, the air pressure is almost negligible. For context, on Falcon 9 flights, main engine cutoff (MECO) occurs around 70km, while the fairings are deployed at > 100km altitude. Thrust increases with increased elevation and decreased ambient air pressure.
