Question

What is relative temperature at 1600ft? (T1600=284.98 K)

(a) 0.989

(b) 0.838

(c) 0.877

(d) 0.999

I have been asked this question in semester exam.

I'm obligated to ask this question of Standard Atmospheric Model topic in chapter Atmosphere and Air Data Measurement of Aircraft Performance

Answer 1

Right option is (a) 0.989

To explain: The answer is 0.989.

Given T1600=241.45K,

From relative temperature (θ)=\(\frac{T_{1600}}{T_0}\)

θ=\(\frac{284.98}{288.15}\)=0.989.
