It is the control planes on the submarine that are the primary method of normally controlling the rate of ascent or descent of the craft. Note that submarines have a few different configurations as regards planes. The stern planes are used alone, or in conjunction with the bow planes, if the boat is equiped with the latter ones, to change what is called "the bubble" or the angle of attack. On some boats, there are planes on what is called the fairwater or sail ("conning tower"), and these, the so-called fairwater planes, can be used to change depth slowly while maneuvering. It is these planes that are instrumental in maintaining depth on a properly trimmed boat as they are centrally mounted, and act to push the "whole boat" down or up without changing the bubble. Ballast tanks are flooded completely to dive and to conduct subsurface operations. The bouyancy of the boat (along with the trim) is controlled by the partially flooding the trim tanks.

What is an ascent rate for scuba diving?
no more than 18 meters per minute
When a firework rocket is on its way up how does gravity affect it?
Gravity slows its rate of ascent.
Do things sink at the same rate in H2O?
No, their rate of descent depends on their "negative bouyancy"...
A hot air ballon begins its descent at a rate of 22 1 2 feet per minute how long will it take for the ballons elevation to change by -901 feet what is its rate of descent?
It is approx 40 minutes and 3 seconds. The rate of descent is 22.5 feet per minute!
A hot air balloon descended 99.6 meters in 12 seconds what was the balloons average rate of descent in meters per second?
"Rate of descent" is a speed; so the idea is to divide the distance by the time.
What is the variometer?
A variometer is a device that is used for indicating the rate of the aircraft's descent or climb.
What is the rate of climb and rate of descent of a passenger airplane?
Depending on the aircraft but most jets and passenger aircraft have a safe climb speed of anywhere between 1800 and 3000 feet per minute. A safe and sensible descent rate for the same aircraft may be between 800 and 2000 feet per minute.
What organs control your breathin and your pulse rate?
Your lungs control your breathing and your heart controls your pulse rate.
What is the average rate of descent of the T-10 military parachute in miles per hour?
35 feet i think
What is the Naval abbreviation for Submarine Sonar Technician?
The designation for my old rate is "STS", which literally stands for "Sonar Technician, Submarines". Yours truly was an STS1/SS during the top years of the Cold War. Check my bio page for pics. The Submarine Sonar community is an oddity in the Navy in that it is separate from the Surface Sonar community, though both share the same rate insignia and Naval lineage. Both have similar missions concerning ASW, but Submarine Sonar and Sonar Tech operations aboard a submarine are critical to submarine operations, whereas it's an ancillary function aboard a surface ship. The rate insignia is denoted by a pair of headphones. The surface equivalent, "STG", stands for "Sonar Technician, Guns".
What doesn't affect rate of descent for a parachute?
Parachutes are interesting aircraft. The major retarding force of classical round parachutes is drag. Weight and drag determine their rate-of-descent. But air spills out of them because they oscillate, too. Since the 1960's parachutes have been designed that acheive lift from their forward motion.
Why does a parachute keep you in the air?
It does not 'keep you in the air' a parachute slows down your rate of descent by traping air under the canopy.
