Since the intoduction of 'typed -in' answers in the CASA Performance exam, a much higher degree of accuracy is required for all calculations.  The CPL Performance book is being updated to include examples of this requirement including ETP and PNR calculations. A summary of the new material may be downloaded from here. ETP PNR download .pdf

Page 129.  Answers to Exercise 4.18 Question 6.  The last line of the working should read 11 gals @ 17.2gh not 8 gals.  The answer given is correct though.

08.11.2018

The new fuel requirements have created a large impact in CPL Performance textbook in regard to variable reserves and as such 50+ pages of exercises and examples have been changed to reflect the new requirements. as such it is just impractical to list the changes in this errata

I have updated the exam preps and E-Text.

Final test . Page 257. Question No 7              Beetle Diagram Fuel at T/O should be 105kg

Page 129

Exercise 4.18 Question 7      Burn 6 gals @17.2gph      =31mins

Should be

Burn 9 gals @17.2gph      =31mins

Page 126                    Exercise 4.6                   6.9 gals   should be  6.6 gals

30.01.2019

Page 100          Error in the Trip fuel calculations answers not changed to reflect the change from 15 to 10 percent

Trip fuel would be:
(180 - 15 - 3) ÷ 1.1 = 141 gal
or

(490 - 41 - 8) ÷ 1.1 = 383 kg

is now

(180 - 15 - 3) ÷ 1.1 = 147 gal
or

(490 - 41 - 8) ÷ 1.1 = 401 kg

Answers to Final Exam page 256 question 6, the working of the pressure height was incorrect the answer states 1667ft.

the correct pressure height is 1757ft.

Page 221. Centre paragraph headed " Radio Survival Equipment".  The last part of that paragraph mentions the carriage of HF Radio.  That no longer applies.  The last sentence should read as follows.

Note that a flight may operate within a designated remote area without an ELT providing flight is less than 50 nm and the required survival equipment is carried ( See CAO 20.11..7.1 and AIP ENR 1.10 para 2.11.(c).

Page 189.  Add the following definition.

ESTIMATED MID-ZONE WEIGHT (ESTIMATED MID-ZONE CRUISE WEIGHT)
The estimated gross weight of an aircraft when half the flight fuel for a particular flight stage has been burnt. The EMZW is frequently used in airline operations to establish a TAS for fuel planning purposes.  It is not a consideration in general aviation where the difference between a TAS based on take-off weight and a TAS based on EMZW is rarely greater than one knot.  The take-off weight is considered accurate enough to establish a TAS for flight planning purposes.

Loading system Bravo in the CASA exam booklet.  If you check out the example on page 11, there is no mention of 'cargo' anywhere. There is also no mention of 'cargo' in the description of the aircraft - only 'baggage'. However on the weight to moment  index graph on page 12, there are two lines, one for 'cargo' and one for 'baggage'. I have only just noticed that after all these years!! I don't know why the 'cargo' reference line is there. There is no extra compartment on the aircraft where you can put 'cargo'. That's a mystery to me.

I usually tell my classes not to use the weight to moment index graph anyway. It is much easier to simply multiply the weight in each location by the arm given in the example table on page 11. In any case, if a question asks for the MINIMUM weight that must be added or removed, you would have to use the baggage compartment because it is the most rearward compartment.  So any weight removed from there would have the greatest effect on the CofG movement.

Page 5.65.  Answer to No 3 in Exercise 5.6 should be 554, noy 555kg.  The max take-off weight in the flow chart should have been 2900 not 2901.

16.06.2014

Page 3.14.  Linear take-off chart example.  Step 7, change 970kg to 950kg.

01.05.20014

Page 5.42.  Exercise 5.11 Question No 1.  The phase 'basic empty weight' should be 'operating weight'.

08.04.2014

Page 1.8.  Revision Questions Topic One.  Question No 2.  Answer [c] should read "in establishing the take off distance required".

19.09.2013

Page 6.3  TAF example on the top of the page.  Validity period should read 2102/2208

03.09.2013

Page 5.32 Question No 12: The gross weight given in the question stem is greater than the MTOW for Charlie and should read 1115kg and not 1125kg. This changes the answer to: "The centre of gravity is 2859 mm aft of the datum and 145 mm inside the aft limit."

26.07.2013

Page 8.10 Question No 5.  Add 'Refer to the take-off chart on Page 19 of the supplement'.

07.02.2013

Minor formatting change on page 1.5 and there's an extra question on page 1.8:

Question No 6
The minimum width of an ALA runway for an aircraft below 2000 kg should not be less than
[a] 45m
[b] 60m
[c] 30m
[d] 10m

Answer [d] (see page 15)
