| ![]() Jeroen, do see the link and notice the RA fluctuation at the bottom of the PFD during an auto land. |

Thanks. Im checked a few Boeing video's too and saw the same behavior. I do wonder how they keep a smooth descent rate with such a jumpy reading? As far as I know/remember the autoland system always uses the RAs, correct? I don't think you can switch to use barometric pressure? Switching from DA to DH only affects the readings on the PFD or does it do anthing else? Jeroen | |

Thanks that makes sense. I remember now, its been a while since I last looked into these systems, or flew with them. No autoland on the Cirrus and Diamond I used to fly. For those interest in this particular incident, in my home country http://www.onderzoeksraad.nl/en/onde...airlines#fasen | |

| ![]() What a brilliant thread this is, currently in Madrid doing my A320 type rating and the entire thread is so exciting to read and there is so much to learn about other aircraft. Am still going through my vpt sessions and really waiting for the FFS to start soon, tons of systems to study and so much hard work to put in right now but i completely love it. |

| ![]() I am so glad I just need to buckle up and allow the pilot to do dew ![]() But awesome thread nevertheless. Goes to show people who love their set of wheels do not differentiate amongst them and are all on t-bhp ![]() |

Senior - BHPian ![]() | ![]() I just booked a 1 hour intro flying experience out here in Phoenix. Excited to do it but the schedule is for a month away! Have a couple of questions: 1 how much fuel a flight consumes in probably a 1 hour flight. I know it depends on the flight but just give us some examples. 2 on a pvt jet do you have a separate terminal which saves you time getting to the airline? Also is there abundant parking area when you fly to a new airport? Is there parking fees etc and do you get a vehicle till your flight the way they show in movies? 3 how much time in advance do the pilots get notified on their next flight or are they on standby like a doctor? 4 where is the fuel on a aircraft stored? Always confused due to the shape of the aircraft. 5 this is my favorite one... Has anybody travelled on a Concorde? If so how was it? I have more queries but will save them for later. Maddy |

1) Depends on the aircraft and the altitude. A very rough ball park for a narrow body jet airliner is about 2100- 2500 Kg/H. 2) All these depends on the airport. Some do and some don't. Parking slot and fee is arranged by prior communication with the aerodrome operator. 3) Depends on where and what you fly. Typically commercial airlines operate on a fixed schedules and so it is easier for them to assign flights to their Crew who usually get their roster for the next month during the end of the previous month. Charter pilots do not have that luxury. 4)IT is always stored in the wings. Additionally, there could be other tanks depending on the manufacturer and the range requirement of the operator. 5) Nope. | |

Distinguished - BHPian ![]() | ![]() You are likely to fly a Cessna or such and they have a fuel consumption somewhere in the range of 6-10 gallons per hour. For jets fuel consumption is also heavily influenced by what altitude you get assigned by ATC. Especially in the USA a lot of the so called FBO (fixed base operator) provide excellent service to private pilots and their planes. The FBOs are they guys that operate the hangars, provide fuel, repair and maintain your plane etc. Especially, if you allow them to fill your plane the rest of their services are often free. They might wave your landing and or ramp fees, if any. And they usually have a few crew cars that you can borrow for free. You are expected to fill up used petrol which is only fair. Fuel is typically stored in the wings and or central fuselage tanks. Planes like the747 have stabiliser tanks as well (out on the tail!). In the early mid eighties I had the pleasure of flying Concorde once. BA had a special promotion. You basically took of and flew for 20 minutes or so. So we never went supersonic. Included was also a BA helicopter ride from Heathrow to Gatwick or vice versa, can't remember. We lived in Brighton, UK at the time and I think I drive to Gatwick, took the helicopter to Heathrow, boarded Concorde etc. It was a very special day. These days you can only visit static Concords in various places around the world Jeroen |

A320/B738/Any typical narrow body airliner
Learjet 60XR
Boeing 777-300 ER - The big baby
Figure 1: This is the fuel plan for a B777-300ER from EGLL-KLAX. Notice the release fuel? Its around 95,000 kgs. By the time of landing, we will burn about 80,000 kgs(i.e around 12, 000 kg REMAINING at KLAX). ![]() Quote:
Figure 2: Fuel Tank locations B777-300ER ![]() Figure 3: Fuel Tank locations Learjet 60XR ![]() Figure 4: This image is from the MFD(multi function display) of the 777-300ER. It shows the total amount of fuel as 102,000 kgs. Green rectangles are the fuel pumps, total of 6. Normally, the center tanks are emptied first and then wing tanks are used. Also, notice the cross feed valves. Generally, the Left fuel pumps supply fuel to left engine & vice versa. The crossfeed valve is used to temporarily connect the two sides of the system. This system allows the shortest route for the fuel and keeps the systems separate, so a leak on one side cannot drain the entire system. The crossfeed valve is generally kept shut for this reason. A || double line indicates a closed valve while a single line indicates a open valve. . ![]() Quote:
Just FYI, I was informed by a friend of mine that GVK has stopped allowing private cars to ferry passengers up to their jets at CSIA, Mumbai. They have started their own service(i.e a Merc/Camry), which picks up passengers from Gate no 8 at CSIA and drops them near the jet. Its costs Rs. 10000 for a 2 minute, 200m trip . ![]() Quote:

| ![]() I have a doubt. When there are two runways parallel to each other and an aircraft intercepts the glide-scope in an ILS how does the ILS system resolve the runway to be chosen to land? Since the resolution between a Left and Right runway will be blurred when the glidescope is intercepted a few miles away and will only become clearer when the aircraft is closer to the runways |

They operate on different radio frequencies. So you do need to make sure you select the correct frequency for the correct runway obviously. On the jet airliner you would choose the appropriate runway on the flight management system. Once you select it, it would automatically set the correct ILS frequency. Even so, this always get verified as part of the pre landing checks. The ILS also sends out a morse code and you can listen into it to verify you got it right. Also, most pilots will call out the runway number once they can read it of the runway. Still planes occasionally land on the wrong runway, sometimes the taxiway amor even the complete wrong airport. But if you ensure you got the correct ILSAe frequency set you should be ok. But check and double check! | |

Distinguished - BHPian ![]() | ![]() Maybe just to add for further clarification to my previous post. In such a scenario each runway would have a dedicated ILS system with dedicated specific respective frequencies. Check this link which will illustrate. See the bottom part with the different runways, each with a specific frequency and ident. The ident is the morse code I mentioned before http://ivao.co.uk/atc/egll/ |
