Q

Agonal

A

En linje på Jorden uden Variation

17
Q

Deviation

A

Vinklen mellem CN og MN

18
Q

Distance, Speed and Time Formel

A 
Distance = Speed * Time
Speed = Distance / Time
Time = Distance / Speed
19
Q

Fuel Consumption Formel

A

Fuel = Fuel Flow * Time
Fuel Flow = Fuel / Time
Time = Fuel / Fuel Flow

20
Q

Heading Definition

A

Direction the aircraft is pointing

21
Q

Track Definition

A

Direction of the aircrafts track over the ground

22
Q

Wind Correction Angle (WCA) Definition

A

Angular difference between heading and track

23

27
Q

Obstacles on map (EU)

A

Skal oplyse hvis hindringer er 100 m (328 ft)

28
Q

Minimum Safe Altitude (MSA) Udregning - Ikke EK Proceduren

A

Højest naturlig hindring + 328 ft eller højeste menneskeskabte hindring + 100 ft (Worst case vælges)

Herefter rundes OP til nærmeste 100 ft (hermed har vi MEF)

Læg + 1000 ft til MEF for at finde MSA (+2000 ft i bjerge >= 5000 ft)

29
Q

Maximum Elevation Figure (MEF) Udregning - Ikke EK Proceduren

A

Højest naturlig hindring + 328 ft eller højeste menneskeskabte hindring +100 ft (Worst case vælges)

Herefter rundes OP til nærmeste 100 ft

30
Q

Rhumbline Definition

A

En linjer der skærer alle meridianer med samme vinkel

31
Q

GC vs Rhumbline

A

GC er den korteste afstand mellem 2 punkter

Rhumbline har konstant kurs mellem 2 punkter, hermed nemmere at følge

32
Q

Flyvehøjde Udregning

A

Højeste Terrænhøjden indenfor 2 NM runded op til nærmeste 50 ft.

Herefter tillægges AGL flyvehøjden.

33
Q

MSA - EK Udregning

A

Obstacles/TN rundes op til nærmeste 100’

Højest naturlig hindring + 400 ft eller højeste menneskeskabte hindring +100 ft (Worst case vælges)

34
Q

Route Abort Altitude (RAA)

A

Udregnes som MSA dog vælges højeste hindring/TN i hele området indenfor ruten (inkl. EKKA til STP og TGT til EKKA)

35
Q

Expected Fuel

A

Den mængde brændstof som forventes at være tilbage i tankene på det pågældende punkt.

36
Q

Continuation Fuel

A

Den mindste mængde brændstof som behøves fra det pågældende punkt, for at kunne fortsætte turen som planlagt, og returnerer til EKKA og lande med 12 gallon

37
Q

Bingo Fuel

A

Den mindste mængde brændstof som behøves for at flyve direkte tilbage til EKKA fra det fjerneste punkt på ruten (afstandsmæssigt ikke tidsmæssigt) og lande med 12 gallon

Q

Lost Procedure: 4 C’er

A

Climb - Bedre udsyn

Confess - Indrøm man er lost for at undgå at gøre situationen værre

Conserve - flyv LF80. Dan et overblik over situation og position

Communicate - Anmod om position i forhold til FSN
