Meteorology

Question 1

ISA+ sıcaklıklarda altimetre neden overreading yapar?

Answer 1

ISA+ sıcaklıklarda, atmosfer basıncı olması gerektiğinden daha düşük olur. Bu durum, altimetrenin düşük yoğunlukta, yani yüksek irtifada olduğunu sanmasına neden olur.

Question 2

When flying high to low T, look out….

Answer 2

Below.
Because altimeter overreading.

(Sanıyorum pressure’da da aynı şekilde.)

Question 3

ISA MSL standards

Temp
Pressure
Density

Answer 3

15C
1013.25 hPa
1225 g/m3

Question 4

From MSL to 11 km (36090 ft) temperature decreases

Answer 4

2C/1000ft

Question 5

From 11 km to 20 km (65617 ft) temperature

Answer 5

Is constant at -56.5 C

Question 6

From 20 km to 32 km temperature

Answer 6

Rises with height at 0.3C per 1000 ft

Question 7

In troposphere temp decrease is 0.65 per

Answer 7

100m.

100m x 3.28 ft/m = 328 ft
Yani 3te 1 oran var… bu ilerde farkli lapse ratelerde onemli

Question 8

@18000 ft -
? HPA
Temp?

Isa

Answer 8

500 hPa
-21.1 C

15C - 36C = 21C

Question 9

200 hPa - 40000 ft (tropopause, -56,5C)
300 hPa - ?
500 hPa - ?
700 hPa - 10000 ft

1013.25 hPa - MSL

Answer 9

300 hPa - 30000 ft
500 hPa - 18000 ft

Question 10

700 hPa - ? ft

Answer 10

10000 ft

Question 11

QHN = ? + elevation / 27ft (?m)

Answer 11

QFE
8m

Question 12

QFE
QNH
SPS

Answer 12

Qfe pressure at field elevation
Qnh qfe reduced to msl using standard conditions
Sps standard pressure settjng (1013 hpa)

Question 13

rİdge = hİgh to low

trOugh = lOw to high
