Meaning of underboost | Babel Free

Definitions

To create too little pressure in an engine's combustion chamber.

Examples

“It enables you to properly time the automatic loading of the entire system so that the regulator will not overboost, which would cause a hunting action, or so that it will not underboost and cause a deficiency in the pressure.”

“A pilot wishing to lose altitude rapidly and still not underboost could go to lower rpm, for example, 16 inches mp with 1600 rpm, rather than 16 inches mp with 2,000 rpm.”

“The only significant problem encountered is that pilots must be particularly cautious about underboosting the engines during the drops.”
