What is the DME voice ident of co-located VOR/DME
-It will be higher pitch
-Transmits only once in 30sec
3 degrees ILS GP angular coverage
-Horizontal 1.35 to 5.25 degrees
-8 degrees each side of localizer
-Distance 10NM
Definition of Relative Humidity
Ratio between actual to saturation mixing ratio x 100
Diameter and life time of Microburst
-1 to 5 minutes
-4km
SNOWTAM validity period

Swept Wing advantages
-Least sensitive to turbulence
-Higher critical MACH number
MNPS and FL

Compressor Stage of Jet Engine
Rotor-Stator
V2 - Vs ratio
V2 = 1.2Vs
Climb Segments and Gradients
1-From 35ft until gear is retracted / any positive
2-From gear is retracted until 400ft / 2.4%
3-From 400ft until clean speed reached / any positive
4-From clean speed reached until 1500ft / 1.2%
Vmca and Vmcg versus Altitude
Both decrease due to lower available thrust caused by lower air density
Vr - Vmca ratio
Vr = 1.05Vmca
What is density altitude
Pressure altitude corrected for non-standard temperature
TUC
-Time of useful consciousness
-41000ft / 12sec
-35000ft / 30-60sec
-30000ft / 1-2min
Normal Max Descent Gradient on Approach
6.5%
IAS to CAS
Applying instrument and position/pressure error correction
CAS to EAS
Compressibility correction
EAS to TAS
Density correction
Climb Gradient Definition
Increase of altitude to horizontal AIR distance
Hydroplanning Speed Formula
9 x Square root of tire pressure (psi)
