Equasions Flashcards
1
Q
Track Error Angle =
A
(DOTX60)/D along trk
2
Q
Max theoretical range=
A
1.23xsqrH1 + 1.23xsqrH2
H=feet
Range=NM
3
Q
ILS GS exetremities?
A
Lower=0.45xG.P
Upper=1.75xG.P
4
Q
Volts (V)=
A
IR
5
Q
Power=
A
IV = Isq X R
6
Q
Frequency (Hz)=
A
RPM X No pole pairs/ 60
7
Q
Range (Land)=
Range (sea)=
A
2 X Sqr PWR (watts)
3 X sqr PWR (watts)
8
Q
Power factor=
A
Kw (real/useful power)/Kva (total/apparent power)
9
Q
PRF(pulse rep freq)=
A
1/PRP (pulse rep period)
10
Q
Pulse radar max range (nm)=
A
C/2 x PRF
11
Q
Minimum range of pulse radar (nm)=
A
C x pulse length/2
12
Q
Thrust=
A
MV
Where V is the delta of air entering vs air exiting
13
Q
Total thrust=
A
M(Vjet-Vflight)+A(pj-p0)
M = mass air flow A = exhaust x section V flight = TAS VJet = exhaust velocity Pj = exhaust static p Po = Ambient static p
14
Q
NAM=
A
NGM x TAS/GS
15
Q
NGM (where TAS known)=
A
NAM x GS/TAS
