For a pressure differential ∆? = p(Stagnation)-p(static)=32lb/ft^2 determine b) the indicated airspeed, in knots (KIAS). (c) the true airspeed, in knots (KTAS), if the aircraft is cruising at an altitude of 7,500 ft above sea level.
An altimeter on a low-speed general aviation aircraft reads 1500 m. The outside air temperature (OAT) is observed to be 7.4°C. The aircraft’s pitot tube measures the pressure of 87050N/m 1. Assuming no calibration is required, at sea-level and under ISA conditions, equivalent airspeed (EAS) and indicated airspeed (IAS) are the same. At any other altitude, equivalent airspeed will be less than indicated airspeed. However, below speeds of approximately 200 knots IAS and at altitudes below 10,000', the difference between...
The pre-2017 Part 23 requirements of the Federal Aviation Regulations required that a single engine aircraft must stall at a maximum of 61 kt. Assume: maximum lift coefficient of 2.5 with flaps, standard day at sea level. Assume the wing is 100% efficient. (a) How big does the wing need to be for a 61 kt stall speed for an aircraft with a gross weight of 4,450 lb (in square feet)? 2. Assume that we plan to operate the airplane...
On a standard day at FL250 you are indicating .7 Mach, approximately what is you True Air Speed? 360 KTAS 390 KTAS 420 KTAS 450 KTAS
Problem 2.2_(AE12.5_Flight_Mechanics) A jet-powered airplane attempts to maximize its range using a constant lift coefficient and constant airspeed flight profile. (a) Estimate the maximum range that the jet could achieve assuming the flight begins at sea level on a standard day. (b) What is the airplane's altitude at the end of the flight? initial weight, 12,000 lbt final weight, Wf - 8,000 lbf wing reference area, S-300 ft induced drag factor, K0.073 zero-lift drag coefficient, cDo 0.023 2
Approximately what size wings would an aircraft need on Mars if its engine generates the same differences in speed as in the "Practice It" ( wing area: 3.50 m2, air flows over the top of the wing at 246 m/s, air flows underneath the wing at 223 m/s) and the total mass of the craft is 300 kg? The density of air on the surface of Mars is approximately one percent Earth's density at sea level, and the acceleration of...

Cach day is approximately normal with man 2900 standard de a) What percent of these men take in more than 3000 calories a day? b) How low calories musta man take in each day in order to be in the bottom of m e
According to the U.S. National Weather Service, at any given moment of any day, approximately 2000 thunderstorms are occurring worldwide. Many of these storms include lightning strikes. Sensitive electronic equipment is used to record the number of lightning strikes worldwide every day. 28 days were selected at random, and the number of lightning strikes on each day was recorded. The sample mean was 8.3 million. Assume the distribution of the number of lightning strikes per day is normal and has...
