Q. 'When the CG position is moved forward, the elevator deflection to achieve a given load factor greater than 1 will be..?
Answer is LARGER:
the rationale given is Moving the C of G forward increases the moment arm of the tailplane.The tailplane provides longitudinal stability,...

QID 811257 Angle of incidence versus attack
Can I just get a clarification.
If a CAA question refers to angle of incidence, is it using this synonomously witth angle of attack?
I believe they are different, but often misused.
Thanks

Qid 310354
Could be wrong but looks like the answer given has the wrong formula.
Answer explanation states "Mass change x distance from mass to old CG/new total mass = change of CG"
I believe this should be "Mass change x distance from mass to NEW CG/OLD total mass = change...

QID 310400 USG to IMG
5600 USG is equivalent to how many Imperial gallons?
Converting US gallons to Imperial gallons you divide by 1.2 which is 4666.6 IG, not 4663 IG which is given as the correct answer....

QID 310335 Operating Mass definition
Suggestion for improvement to the materials, after I put OM = DOM + Ramp Fuel, instead of OM = DOM + TAKEOFF Fuel
Answer saysIf you learn the diagram this goes a long way to solving all of the probable mass and balance 'definition' questions you're likely to get in the exam. This can then

QID 310451, if they can pedants so can I!
A triwheel aircraft has a datum 25 cms aft of the nosewheel which weighs 125 lbs.
The main gear is 180 cms aft of the datum, each main gear weighs 3000 lbs.
The distance between the nose gear and main gear is 205 cms.
Calculate the BEM and CG.
Perhaps the datum weighs125...

Colin, thank you! CAA expects such precision in our answers and yet their questions are so vague. We are to assume that 'standard' is set and the climb is to FL55, not altitude 5,500'. I guess in the absence of any other pressure information, the only logical conclusion is that we have 1013 set.

SEP Climb graph QID N320419
Having a 'moment' on this question. It seems simple but I just can't get anwhere near the suggested answers!
Its' SEP climb graph. I slide across the graph and with a calculated TAS at approx 110kts i get a graphical climb gradient of 8.5%. With a 'rise' of 5,500' and a gradient of 0.085,...
