Pre-flight planning: The route plan Flashcards
Dead Reckoning
estimating the direction and distance travelled rather than by using landmarks or astronomical observations.
VOR Compass rose is magnetic or true
Magnetic
1nm equal to X km?
1.852
Whats the name of the vent of the barometer / altimeter
static vent
Height
Vertical distance from ground
AGL
height above ground level
AAL
height Above aerodrome level
Altitude
vertical distance from sea level
AMSL
Above mean sea level
How to calculate density altitude
- Calculate the pressure altitude at a given point (when QNH is 1013hPa)
- Calculate the temp. deviation from ISA (AT PRESSURE ALTITUDE)
- Calculate density altitude by applying the correction of 120ft per 1°celsius
What is density altitude used to calculate for
Critical performance calculations, such as takeoff and landing
ASR
Altimeter setting region
Semicircular Level System (/rule)
Cruising levels to maintain separation
0°M-179°M Cruising Altitudes for IFR and VFR
IFR: 1000ft, intervals of 2000ft
VFR: Odd ft + 500 ft, eg: 3500ft, 5500ft
180°M-359°M Cruising altitudes for IFR and VFR
IFR: 2000ft, intervals of 2000ft
VFR: Even ft + 500ft, eg: 4500ft, 6500ft
Flying at FL60 over terrain which is 1750AMSL
Local QNH 998hPa. ISA temp.
What is the height above the terrian
3800ft
ASI
Airspeed indicator
How air speed is measured
using the pitot-static systme (pitot tube)
Dynamic pressure
Like the feeling when you put the hand out of the car’s window. The faster it drives, the more wind you feel on the hand, the more dynamic pressure.
