Feedback from the UK CAA FCL Exams:
Late June / Early July 2022: ATO Feedback for teaching purposes…
Although there were no queries this month, please see the following feedback from our SMEs:
031 Mass and Balance
The following questions/topics are frequently noted as being answered incorrectly:
Questions requiring the calculation of Traffic Load given standard tables and associated information. These questions are examining LO 031.02.03.03.02 Calculate the traffic load by using standard masses. Interpreting the standard mass information and using it correctly seems to be presenting difficulties.
Questions requiring the calculation of a moment change considering a flap retraction (LO 031.04.01.04.01).
Questions asking the candidate to find the Centre of Gravity for landing given a stated fuel consumption during the flight. (LO 031.04.01.07.02 Explain and calculate aircraft CG movement as flight progresses given location of fuel tank (inner wing, outer wing, central, additional aft central, horizontal stabiliser) and mass of fuel consumed from that tank and aeroplane’s previous CG).
032 Aircraft Performance
The following question/topics are frequently noted as being answered incorrectly:
Finding stalling speed for a given weight, using for example the data provided in the table above the graph in CAP 698, Section 2 - SEP1, Figure 2.1. (LO 032.02.01.01.02 Describe the limitations on VR, on the speed at 50 ft above the take- off surface and on VREF, and given the appropriate stall speed, estimate the values based on these limitations for a single-engine, class B aeroplane).
Calculating the TODR given stated conditions using for example the data provided in CAP 698, Section 3 - MEP1, Figure 3.1. There seems to be confusion around the correct application of the regulatory factors for an ‘un-balanced field’ case. (LO 032.03.03.01.03 Determine the ground-roll distance and take-off distance from graphs).
Find the brake cooling time from an RTO given stated conditions using for example the graph in CAP 698, Section 4 - MRJT1, Figure 4.31. (LO 032.05.01.01.10 Calculate the break cooling time following a rejected take-off given appropriate data).
033 Flight Planning and Monitoring
Questions examining LO 033.01.01.02.01 Choose visual waypoints in accordance with specified criteria (large, unique, contrast, vertical extent, etc.) are often answered incorrectly. Candidates should be aware of good examples of features to select for VFR navigation, considering the criteria stated in the LO, and of course features that would be unsuitable for use.
Although this has been noted previously, altimetry questions requiring the temperature error of the altimeter to be taken in consideration continue to be frequently answered incorrectly. Looking at the answers selected or entered it is clear that the main source of confusion is around which value to use for the altitude range in the formula: 4 x ISA deviation x altitude (in thousands of feet). In questions where a pressure difference has also to be taken into account this should be resolved first and this answer used to determine the vertical distance above the appropriate datum through which the temperature error should then be calculated. Any stipulated terrain clearance should also be ‘added in’ to this range before carrying out the temperature error calculation.
