Flight plan

Question 1

Flight plan: To/From

Answer 1

These are the start points and end points of each leg, TOC and TOD are included in these

Question 2

Flight plan: Alt ft

Answer 2

The altitudes of each leg using the altitude selection procedure, note that for climb/descent leg you will need to insert both starting and finishing altitudes into the table using a /

Question 3

Flight plan: What is mean alt in climb and descent rounded to

Answer 3

nearest 500ft

Question 4

Flight plan: CAS

Answer 4

Given in operational data

Question 5

Flight plan: Temp

Answer 5

This is the temperature at the altitude of the leg, it will either be given as a freezing level and so you must use the temp lapse rate of 2/1000ft or it will be given at certain altitudes and you must interpolate

Question 6

Flight plan: How is the mean temp for the climb/descent legs worked out

Answer 6

• For the climb it is taken at 2/3 of the way up and noted as (temp/altitude 2/3 of way up)
• For descent it is taken at the 1/2 way down point and noted as (1/2 way down alt\temp)

Question 7

Flight plan: What are temps rounded to

Answer 7

Nearest whole degree

Question 8

Flight plan: TAS

Answer 8

Calculated using nav computer and input CAS, temp and alt. For climb and descent the 2/3 and 1/2 way point are used.

Question 9

Route selection considerations

Answer 9

Weather and airspace

Question 10

Selection of cruise alt

Answer 10

• Height of terrain combined with a/c performance: 500ft above highest spot height combined with optimal a/c and engine performance data from flight manual
• Weather: cloud base, FZL, W/V
• ATC requirements
• VHF radio reception
• Magnetic track/ alt requirements

Question 11

Magnetic track/ alt requirements

Answer 11

VFR always 500ft

• Flying north (270 to 089) odd numbered alts e.g. 3500ft
• Flying South (090 to 269) even numbered alts e.g. 4500ft

Question 12

Fuel planning - calculating fuel consumption rate for a given leg

Answer 12

Found in the the a/c flight manual on the cruise performance chart, by using the AUW, TAS and cruise alt, consumption rate can be interpolated

Question 13

Calculate minimum fuel required for a flight

Answer 13

Add together:

• all zone fuel requirements
• quantity of the 30 min reserve
• amount for taxi, takeoff, climb, approach and landing

Question 14

How is reserve fuel requirement calculated

Answer 14

30 mins at holding consumption rate

Question 15

Latest time of departure

Answer 15

Calculated using the daylight table, if the flight is restricted to day only, it must operate between MCT and ECT so using the daylight table for the zone you are landing in work out the ECT on the date specified and subtract your flight time

Question 16

Max holding time for a given leg

Answer 16

Max holding time will involve you flying for max endurance (burning the least amount of fuel and therefore using the lowest power setting to remain airborne)

Question 17

Flight plan: cruise leg distance and time

Answer 17

Track distance for each leg can be measured with a protractor/nav ruler and then leg time is calculated using ground speed

Question 18

Flight plan: climb and descent legs time and distance

Answer 18

Time to TOD and TOC can be calculated using ROD/ROC info, then distance to TOC/TOD can be calculated using the time and G/S. Once you’ve identified the distance to TOC and TOD you can subtract this off the distance of the first and last legs to give you the distance of the cruise portion of the first and last legs.

Question 19

Flight plan: what are distances rounded to

Answer 19

The nearest nm

Question 20

Flight plan: what is time rounded to

Answer 20

The nearest half/whole minute

Question 21

Flight plan: wind velocities

Answer 21

Wind direction is provided by metservice in °T, for the climb portion of the leg the 2/3 of the way up point is used, for the descent portion the 1/2 way down point is used, using the wind velocities provided interpolate to find the wind velocity at the altitude in question to the nearest °T and nearest kt

Question 22

Flight plan: HDG °T and G/S

Answer 22

Using triangle of velocities method on nav computer

Question 23

Flight plan: HDG °M and °C

Answer 23

°T +/- Variation = °M +/- deviation = °C

• variation amount is found on VPC/VNC and the variation line/isogonal that applies to the greater part of the leg is used
• deviation is found by applying the compass deviation card

Question 24

If deviation/variation is west

Answer 24

Add (west is best)

Question 25

If deviation/variation is east

Answer 25

Subtract (east is least)

Question 26

Flight Plan: ETA/EET

Answer 26

EET can be calculated by adding all leg times together and adding the total to the ETD will give ETA (once you know ETA SARTIME can be decided)
