	Rate of climb - Wikipedia, the free encyclopedia
		In aerodynamics, the rate of climb is the speed at which an aircraft increases its altitude.
		The rate of decrease in altitude is referred to as the rate of descent.
		Vx refers to the "best angle of climb speed," which is usually less than Vy, the "best rate of climb speed." The difference between these speeds relating to the rate of climb lie in the climb objective.

		For example an exchange rate of 120 Japanese yen (JPY, ¥) to the United States dollar (USD, $) means that JPY 120 is worth the same as USD 1.
		Exchange rates for such currencies are likely to change almost constantly as quoted on financial markets, mainly by banks, around the world.
		The nominal exchange rate is the rate at which an organisation can trade the currency of one country for the currency of another.

	System for reducing aircraft fuel consumption - Patent 4159088
		Mode I logic, therefore, causes the sensed value of rate of climb h to be maintained at least within a reference value r.sub.1 of an optimum value, and the reference value r.sub.1 may be, for example, on the order of two percent of a typical value of h.
		The goal of mode I operation is to maintain aircraft rate of climb at substantially maximum values during a climb portion of the flight by maintaining the pitch attitude at optimum settings P.sup.1 where the slope of the rate of climb vs. pitch attitude curve is zero.
		It has been determined that by maintaining the rate of climb of the aircraft at or near maximum while holding aircraft thrust constant at a rated maximum, the greatest possible contribution is made during climb to minimizing the total quantity of fuel consumed during an entire flight.

	GIVEN:
		A time to climb to the minimum required altitude (minus the initial 2000ft) is calculated, as is the time to cruise to the home field.
		This total time for different rates of climb will be compared to ascertain the most efficient altitude to leave the last thermal (i.e.: minimum time is most efficient).
		Cases 1, 2, 3, and 4 are for rates of climb of 2, 3, 4, and 5 kts.

	Effects of horizontal gusts on Total Energy variometers
		Audio signals which vary with rate of climb/descent are also possible when electronic sensing is used and this is a great help in keeping pilots looking outside the cockpit for other traffic, gliders or birds climbing better in nearby thermals and interesting and/or useful meteorological phenomena.
		These may easily exceed and swamp the rates of climb due to airmass rising and falling (a 30 degree pullup from 100 knots gives an initial rate of climb of 50 knots, causing the +/- 10 knot scale variometer to indicate uselessly at the top of its scale).
		These sink rate changes can mask small changes in the airmass and make it difficult to pick the best path through the air.(which is the path with the most and fastest rising air and the least and slowest sinking air).

	Airdisaster.Com Forums - Rate of climb
		An important concept to understand is that the pitch angle of the plane may have little relation to the rate of climb.
		All of this has to do with the concept of "angle of attack" and the end result is that while sitting inside the cabin or watching the plane from the ground, you can tell very little about the climb rate from simply estimating the the pitch angle of the aircraft.
		I may fly a constant speed or in some cases, a desired vertical speed (rate of climb), but the required pitch angle will vary from flight to flight depending on the weight of the plane or the environmental conditions.

		It then climbs with a constant speed of 88 km/h along a straight line, just celaring a power line 15m high at a horizontal distance of 460 m from it initial position.
		The first thing that you need to recognize is that "rate of climb" means the same thing as "y-component of velocity while climbing".
		Since they give you the speed along that straight line tracjectory, finding the rate of climb should be easy after you get the angle.

		So, imho the P-38J climb rate is still porked, you should not have to destroy the engines or fly on fumes to get close to the TTC numbers.
		The ROC is the climb rate per altitude, and as you can see, the in game P38 has a lower ROC than the real life P38 at all altitudes.
		Rate of climb is merely a measurement of change in altitude over time, a behavior of the plane that results from the deployment of the plane's energy in a certain manner.

	How Fast Will The Cremation Rate Really Climb?
		Death care industry professionals in the United States have always kept track of the cremation rate in their local community by the number of requests they receive annually.
		On the national level, the Cremation Association of North America (CANA) is the organization everyone--including the media--most closely watches for past, current and projected cremation rate figures which are used partly to help justify the purchase of cremation equipment and columbariums or plans for new or expanded memorialization projects such as cremation gardens.
		This uncertainty is only heightened by the release of the results of the latest installment of the annual five-year survey by Wirthlin Worldwide of 1,000 adult Americans aged 40 and older which demonstrates that cremation and pre-planning continue to grow and solidify as mainstays in consumer funeral service preferences.

	Climb
		The climb is the part of a flight of an aircraft, after take off, consisting of getting the aircraft to the desired cruising altitude.
		A pilot generally induces a plane to climb by setting the appropriate power level and using elevators to adjust the pitch of the plane for the appropriate speed.
		For lighter aircraft this method can achieve faster rates of climb than by using engine power.

	IHS ESDU: Data Item 92019
		ESDU 92019 presents the equations with varying degrees of simplification for the calculation of rate of climb of jet-powered or propeller-driven aeroplanes.
		It is primarily concerned with "steady-state climbs", that is with instantaneous climb rate, and does not treat the effect of acceleration introduced by a climb schedule.
		For propeller-driven aeroplanes, approximate guidance is given graphically on maximum climb rate as a function of power/weight ratio.

		The climb performance was determined by recording the airspeed and rate-of-climb at several altitudes between ground level and 6000 ft. The effects of the flaps on the lift and drag characteristics were also studied.
		It was found that the Bonanza had the fastest rate of climb at approximately 84 knots which produced a maximum rate of climb of 650 ft/min.
		The data were fitted with a second order polynomial and the maximum rate of climb and the maximum flight path angle were calculated from the equation of the curve fit.

		F.S. gear climbs to 30,000 feet and M.S. gear climbs to 20,000 feet were made with the radiator flaps open.
		In addition, two climbs in F.S. gear with the radiator flaps closed were made for comparison with results as obtained by the firms.
		An increase of about 950 ft/min in rate of climb and about 30 mph in all-out level speed is achieved by the increase of boost from +18 lb/sq.in.

	Business: Interest rate likely to climb
		Poole said the general trend for interest rates will be higher as the Fed moves toward a more neutral stance for monetary policy.
		The central bank last year pushed interest rates to a 46-year low of 1 percent on the federal funds rate, which is the interest that banks charge each other.
		The drop in such spending was the chief reason that the annual growth rate was 2.8 percent in the April-June quarter, compared with 4.5 percent rate in the first three months of the year.

	Rate Climb Thickens The REIT Plot (Site not responding. Last check: 2007-10-23)
		Fitch Ratings believes that the effects may not be as dire as some would think since the short-term rate increases that affect variable-rate debt would only modestly cut into debt service ratios for the majority of rated REITs.
		These metric declines shouldn’t have widespread ratings implications, except for companies with debt-service ratios that are already at the low end of their ratings category.
		“We expect the effect of rising rates to be uneven, disproportionately affecting companies depending on their variable rate debt exposure and their laddered debt maturities,” says Tara Innes, managing director at Fitch Ratings.

		Ratings are devised such that the ratio of two ratings is proportional to the ratio of the odds of success that a climber of a particular onsight level would have climbing routes at those grades.
		I'm sure that is the accepted standard, long ago established as anyone should know, but the climbs I've rated (ice climbs, if that matters to you), I just climbed, and said, feels like a WI4.
		A 5.10 climb would be about 10 feet high, and a 5.12, 12 feet high, etc. A 5.12b would be about 12 feet 4 inches I think.

	IHS ESDU: Data Item PERF RT1/2
		ESDU Perf RT1/2 illustrates, through a worked example, the correction of measured rate of climb data to conditions of aircraft weight, engine speed and atmosphere different from those at the time of test.
		However, provided maximum rate of climb is being measured the error in using a fixed schedule of equivalent airspeed and height is negligible.
		Based on the relationship developed in ESDU Perf RT1/0 the graph plots rate of climb divided by root relative temperature against engine speed divided by root relative temperature and, in this case, jet pipe temperature divided by relative temperature although it could equally have been turbine inlet temperature or propeller pitch angle.

	Ambient Temps And Rate Of Climb? - RC Groups
		I have been flying my Kelly in temps of 95 to 100 F. I have had a few pretty good climbs with it in light air, but lately it seems that I can only get to about 250 to 300 feet before it levels off and just can't seem to climb anymore.
		I have found that when I start my launch its easier to climb out and then seems to get more difficult to attain the same rate of climb the higher it gets.
		I have also noticed that it's easier to judge the angle of attack the closer it is to you.

		The climb angle is the angle of the Flight Path measured from the horizon.
		This is true because of the angle of attack, as discussed in the lift chapter.
		Thus both the rate and angle of climb decrease.
