Inhumane Factors and Digital Duty Limits Human bodies are not digital and do not run on laws of mathematics. Therefore, we need to pay more attention to chemistry rather than mathematics and consider biological clocks instead of digital ones. Operational cost is the usual barrier in resolving issues like these. The choice is either “Less Profit More Safety” OR “More Profit Less Safety”. Monetary night allowance cannot mitigate fatigue or drowsiness, it is just good to keep the mouth shut. Resolution of this issue needs a concerted effort by the regulating authorities and operators to design so ..read more

The trip fuel for a jet aero plane to fly from the departure aerodrome to the destination aerodrome is 5350kg. Fuel consumption in holding mode is 6000kg/h. The quantity of fuel which is needed to carry out on go-around and land on the alternate airfield is 4380kg.The destination aerodrome has a single runway. What is the minimum quantity of fuel which should be on board at take-off? a) 14730kg b) 11730kg c) 13230kg d) 13000kg. Ans: 13 230 Kg The contingency is either 5% of the trip fuel, or 5 minutes worth of fuel at holding consumption rate, whichever is greater. 5% of 5350 Kg is 276 Kg b ..read more

A320 73 tons FL340 ISA +4 Wind 279/71 GS 406 TAS 455 IAS 270 Mach .785 Flying on a heading of 235 deg, made a 90 deg right turn in heading select mode. Bank angle selected for the turn by computer was 15 degrees. Since turn was stable at a constant bank angle of 15 degrees, turn was discontinued and on reaching heading 270 (where wind 274/72, TAS 461) a left turn direct to the waypoint on the airway was made. This time NAV mode was engaged to fly direct to the waypoint. The computer selected 20 degrees bank angle for this turn. I guess Ryan Air has a Boeing fleet, that's why they are able to ..read more

Thank you very much , it's all very interesting ! Do you remember , by chance , a few angles by which the autopilot banked the aircraft when making turns of more than 20 degrees at high altitude - above fl 300 ? Without them I cannot calculate radiuses . Statistics: Posted by ATC Route — Sat Feb 18, 2023 4:17 pm ..read more

For a mild situation — heading changes as requested by ATC — wont be bothered with bank angles as computers will handle that. For collision situations — TCAS — wont be bothered with turns unless some extreme case Ryan air policy — not in my company — not sure about others Normally in cruise the legs are straight with shallow turns so I guess 10 deg are enough. Though it would be interesting to see how much would the bank angle be used by computers at higher levels for a 90 deg turn. I think will try it tonight Statistics: Posted by K.Haroon — Fri Feb 17, 2023 1:50 pm ..read more
