AND ANSWERS 2025/2026 ALL GRADED A+
✔✔What is the FADEC and its purpose. - ✔✔Full authority digital electrical control -
receives aircraft and engine sensor information and determines the appropriate engine
scheduling to operate the engine in all areas of the flight envelope.
✔✔what are the limits of the green arc on the speed tape - ✔✔VNO
VS1
✔✔what are some facts about the DA42 - ✔✔VN0 - 151 kts
VNE - 188
VYSE - 85kts
ILS speed - 100kts
VX+VX = 79kts
Cruise - 130kts - 80% power
Max TOW - 1900kgs
Max Landing -1800kgs
Full Fuel - 95 per side
6 gallons an hour at cruise
✔✔when can you descend on the glide path? - ✔✔once cleared for the approach
within +- 5 degrees of localiser
✔✔what is an isobar? - ✔✔points of equal pressure
✔✔what are planning minima's - ✔✔always one worse than actual
✔✔what is an inversion? - ✔✔a layer of warm air that is trapped by high pressure above
and cold air below
often cause poor vis and status clouds in the inversion
✔✔what cause dutch roll? - ✔✔lateral stability stronger than directional stability
wings roll
✔✔what is the crew make up for the A320 and A321? - ✔✔A320 - 2 pilots 4 cabin crew
A321 - 2 pilots 5 cabin crew
✔✔What is cos(60 degrees)? - ✔✔0.5
✔✔what is Tan45? - ✔✔1
✔✔what is sin90? and Sin30? - ✔✔sin30 = 0.5
Sin90 = 1
,✔✔what's are the 6 bus bars? - ✔✔emergency
essential
non - essential
battery
hot
ground
✔✔how many Kms in a NM? - ✔✔1.852
✔✔how many litres are in a gallon - ✔✔4.546
✔✔how any gallons are in a US Gallon - ✔✔1.2
✔✔how many pounds in a kilogram - ✔✔2.2
✔✔what is rate of descent for a 3 degree glide slope? - ✔✔5 x Ground speed
✔✔What is pressure altitude? - ✔✔the altitude when 1013 is set on the altimeter
✔✔with high humidity in the air more or less dense? - ✔✔less dense
The water molecules push the air molecules apart
therefore aircraft performance will be less on humid days
✔✔what is density altitude? - ✔✔pressure altitude correct for none standard
temperature
the altitude the aircraft will perform at for those given conditions
✔✔what is the hydraulic pressure for a A320? - ✔✔3000 PSi
✔✔what are given by an airports code and letter? - ✔✔Airport field length
Wingspan
Outer main gear wheel span
1A - Less than 800 m, <15m , <4.5m
1B
3C
4D,E

ILS Loc
VOR/DME
VOR
, NDB - ✔✔ILS Loc - 250ft
VOR/DME - 250ft

NDB- 300ft
✔✔what is Vmd? - ✔✔minmum drag speed
✔✔What is ECAM - ✔✔Electronic Centralised Aircraft Monitoring
✔✔what does ETOPS stand for and what is it? - ✔✔Extended Twin Operations
An operator has been granted permission to extend the alternate range to beyond
60mins single engine
60-180 mins
A320 - 350nm
✔✔what are the IFR flight levels - ✔✔360 - 179 degrees - ODD - 10,30,50
180 - 359 ~degrees - even -20,40,60
✔✔What is RVSM airspace? - ✔✔Reduced Vertical Separation Minimum (FL 290-410).
and Gain fuel saving and operating efficiency by flying at more fuel efficient FLs and on
more user preferred routes.
Equipment must be certified and crews qualified
two independent alternators -must be within + or - 200ft of each other,
two Air Data computers
at least one autopilot with altitude maintaining function
Altitude deviation alert system
SSR Transponder mode C
2 long range navigation systems
✔✔what power setting is assumed for VMCA and VMCG? - ✔✔take off power
always the worse scenario
✔✔when must the crew call either a pan or mayday for a fuel emergency? - ✔✔Pan -
Maybe land with less than final reserve
mayday - WILL land with less than final reserve
✔✔why will a air driven artificial horizon indicate nose up during takeoff? - ✔✔due to the
action of the pendulous vane
✔✔What is a holdover time? - ✔✔The estimated length of time that deice/ anti-ice fluid
will prevent the accumulation of ice/snow/frost on the aircraft.
for 1 step the time starts at the beginning of the operation
for 2 step it starts at the beginning of the second step
