Move it closer to departure airport

Question 10

What is the formula for flight fuel?

Answer 10

(Distance x Fuel Flow) / Ground Speed

Question 11

What is the formula for flight fuel available with gallons?

Answer 11

(Fuel at take off - 3 - 15) / 1.15

Question 12

What is the formula for flight fuel available with kg?

Answer 12

(Fuel at take off - 8 - 41) / 1.15

Question 13

What is the formula for minimum fuel with kg?

Answer 13

(Flight fuel x 1.15) + 41

Question 14

What is the climb performance weight limit imposed to ensure?

Answer 14

That the aircraft will achieve a 3.2% climb gradient in the landing configuration

Question 15

What consideration determines whether a aircraft is in the normal, utility or aerobatic category?

Answer 15

Maximum positive and negative load factor

Question 16

Time to PNR formula?

Answer 16

(Safe endurance x GS home) / 2 x TAS

Question 17

Safe endurance formula?

Answer 17

(Start fuel + taxi + fixed) / 1.15

will get you in galons or kilos, then need to convert to minutes using fuel flow

Question 18

What is the formula for distance to ETP?

Answer 18

(Total distance x GS home) / (GS on + GS home)

Question 19

What is forward limit formula?

Answer 19

(Present weight - 2360) x 0.27 + 2400

Question 20

What is GNMPG formula?

Answer 20

Ground Speed / Fuel Flow

Question 21

A centre of gravity range is imposed on an aircraft to ensure that?

Answer 21

The aircraft will be controlable during flight

Question 22

Where will the centre of gravity move and why if fuel is burnt from aux tanks in Echo aircraft?

Answer 22

Move forward because aux tanks are behind CoG

Question 23

What is the supplementary take off distance?

Answer 23

Distance from beginning of take off distance available to point on strip where prescribed obstacle free gradient is available

Question 24

The effect of loading an aeroplane with CoG forward of the forward limit is that?

Answer 24

Elevator effectiveness is reduced

Question 25

What is the %MAC formula?

Answer 25

(Centre of gravity mm aft of datum - 2190) / 19

Question 26

What is the formula for time to ETP?

Answer 26

(Distance to ETP x 60) / GS ON

Question 27

Weight to shift formula when only given index units?

Answer 27

(Index units x 10000) / Change of arm

Question 28

An Echo is loaded at take off so that the centre of gravity is exactly on the forward limit of the permitting range. If fuel is burnt from the aux tanks, what happens to the centre of gravity?

Answer 28

Moves forward and remains in the envelope
