We fly to the sun ! Flights planning

OFP : planning sheets suggest your several spreadsheet templates to prepare your flight in the B727, B737, B757, Embraer 175 et 195 and AVRO RJ.

Beware that the very last version of those sheets is only included and integrated in YART, Yet Another Route Tool, where they are automaticcaly produced from your flight data.

Prepare your route, then, using your tables and filling the weight form, prepare your fuel form in this document. A copy of some tables (weights and limitations) for each type (B737,B757...) are embedded.

Some extra data are also reported in the data tab. You can check the speed for gear extension, the A/P limitations, some RNP informations or an advisory N1 for reduced thrust takeoff in the sheet ! When it is ready, go the "Briefing" which is the dispatcher briefing and sign it to complete it automatically with the captain notes. In the end, export the dispatcher briefing as a selection in PDF if you wish.

The best method to set up the 125 MHz controls that the MJC84 simulation provides it to look for the usb game controllers box of Windows.

In the picture below, we start the USB game controller dialog box

In the picture below we show the Game controller as well as an extract of the mjc84.ini file

In the example above, each device has been identified from bottom to top in the game controller box. This order has been kept to set up the mjc84.ini file located in SimObjects/Airplanes/Q400/ini.

As the Flight sim Yoke is in position #4 (starting with zero), it becomes J4 in the INI file.

To determine if an axis is "X", "Y" or is named "R", start the registred version of FSUIPC if you have it. Moving the selected axis in FSPUIC interface will present you the name of the axis, either X, Y or R. In the example above, the rudder axis of the Combat Rudder Pedals was found to be the axis "R" in FSUIPC. By trials and errors (to discriminate between Rx, Ry and Rz), this could then be set to Rz in the INI file.

Fuel efficiency, ECON speed and cost index (CI)

Fuel prices updated each week (external link).
AirBP aviation fuel catalog.

Economical speed is calculated using a cost index which allows balance between time of flight and consummed fuel. The CI is defined as the quotient of all time-dependants factors over the fuel price.

In 2012, the average fuel price was 310 cts/gal. The density of jetA-1 fuel is 6,6 lb/gal so fuel price was about 47 cts/lb. Divide time-related exploitation costs by this value. For instance : 1700 $.h-1 / 46,7 cts.lb1 = 36 (about).

Among several sources on the web, you'll find that exploitation cost (excluding fuel cost) is variable. It sounds normal as this cost is influenced by multiples parameters. Think of the age of the aircraft, airline economical model (including bying or leasing aircraft, level of customer services, maintenance strategy) or airports fees and so on.

Using two different and concording sources, we previously used 1700 $ per hour for our B737NG. This cost may be a strategical and confidential data for most airline managers but a small search on the Internet may lead you to a better overview of the possible values. The calculation here provides CI36, which is exactly the CI-value used by some european carriers in 2012.

When fuel price rises, the according reduction of the CI will maintain an economical efficiency while operating the airplane. Indeed, entering a low CI in the flight computer orders a slow ECON speed, thus the plane is consumming less fuel. On the other hand, if exploitation cost increases (salary augmentation, aging aircraft kept in service...) CI rises. Setting a high CI in the flight computer allows to fly faster, thus minimising the time of flight.

Proprietary datasets (and, by the way, payware products !)

Don't like to do free add, however, we hardly can avoid pointing those accurate datasets with real world strict compliance per AIRAC.

Free datasets (Free as in free bier and as in freedom)

X-Plane relies upon publicly-available, freely-available data sources. We cannot reverse-engineer proprietary databases and use that data. Of course, it is hard to find high-quality, global data that meet these criteria.

This licence means that if you want, you want, it is possible to build a dataset for your aircraft in MS Flight Simulator from this data.

The X-Plane airport and navigation data is stored in a set of text files.  The file and/or folder names have changed with the release of X-Plane 9.0, but the scope of each file remains unchanged:

Pilot documentation by IVAO France. Sceneries

The minimal update concept is a way to update a scenery with the minimum of work. It could be to add a building for instance. We don't want to add a close 3D model of the real building, but we want at least to depict the building location and general shape. Therefore we use a generic building of the FS library. This way, the updated scenery can take into account modifications that occured at the real airport without having too much work to do.

RNAV(GNSS) approaches

Please find below the RNAV(GNSS) approaches for FS9/FSX GPS and ATC.

The goal of the RNAV(GNSS) project is to provide in the flight simulator world the developping RNAV(GNSS) approaches.

Where a radar guidance by ATC is applicable per published procedure a fictionnal "radar waypoint" has been set. This way the GPS or the ATC will make you fly a realistic heading where the transition and the approach itself are separated per the published radar guidance. The nomenclature of this fictionnal radar waypoint is RADxx where xx is two numbers.

Classical approaches are still presented in those files but only the RNAV(GNSS) ones are updated with their correct transitions.

Updating P3D default navigation data is now possible

Presenting FSAeroData Service

Updating P3D default navigation data is now possible since a company has now translated the Jeppesen data from Navigraph into BGL files for FSX and P3D. In this review, we tested a 3 months subscription at FSAeroData for a small fee. (You also need a valid Navigraph subscription, which is checked during the activation process to unlock the download of the BGLs).

The update brings three new directories. Per default, they are stored in your Document directory, which I dislike and I moved them later to my scenery directory. The activation of the new data is a matter of adding those folders into scenery.cfg, on top of your other sceneries.

The original data is kept untouched in Scenery / World / scenery and are just taken over by the new files due to their higher priority.

Here are the results.

In the pictures below, we show the communication frequencies available at LFLC Clermont-Ferrand airport in France before (first picture) and after (second picture) the update with the BGLs from fsAerodata. You can see an increase in available frequencies. A crosscheck with the AIP confirms they are now up to date.

Then below, we show the airpace around LFLC Clermont-Ferrand airport before (first picture) and after (second picture) the update with the BGLs from fsAerodata. You can see an increase in depicted volumes ith accurate (not shown) vertical limits. A crosscheck with the AIP confirms they are now up to date.

In the next panel below, we show the improved airspace around LGSA airport, as well as added IFR procedures for LGIR including the very new RNP APCH for runway 27. We show the default location of the BGLs in the Documents folder as well as a screenshot of the fsAerodata automated tool to download and activate the scenery. But we also show that approaches with RF-legs are not fully supported.

In the end, this is a fresh start for the simulator and for add-ons that use the default FS or P3D navigation databank. For people using liners with their own databank, then it will be usefull to gather the recent Navaids. If you use the default ATC, it will be also usefull rather than cheat the software and ask the ATC for the old approaches when you will be in fact flying the recent approaches from your FMS. I don't think it is usefull to update on a monthly basis however. Getting fresh 2017 data today (and keep it for a few months without updating at each AIRAC) seems fair enough. Since we did learn how to fly in a very outadated simulator since today we might afford that compromise.

RNAV / RNP approaches - introduction

RNAV capability is mandatory in the French airspace upside FL115 with navigation accuracy of 5NM during 95% of the time of flight. This is called B-RNAV capability or RNAV-5. Following a RNAV route in a Terminal area requires equipment to do RNAV-1. RNAV capability is provided with multiple sensors. VOR/DME, IRS and satellites may be used by FMC to compute an integrated localisation in space. But RNAV is not the only performance-based navigation (PBN). RNP are the other category of PBN procedures (see illustration 1). They require even more performance in the navigation. In term of accuracy, they can be like RNAV-0,3 (and even RNAV-0,1 and RNAV-0,05). Those approaches are designated with RNP-3,0 (or RNP-0,10 AR for RNP with special autorisation required or RNP AR). They use GNSS (global navigation satellite system) as primary source of positionning. In France, civil aviation autority stated that RNP basic approached are denominated as RNAV(GNSS) and RNP AR as RNAV(RNP).

RNP and home flight simulators

First of all, use a recent navigation database. Before 2010, no RNP APP will be provided in your virtuel aircraft. iFly 737 (with last update 3.1) and PMDG NGX are able to follow RNP approaches. If your lateral and vertical guidance lakes of accuracy (like in Wilco/Feelthere Airbus) cheat and use ILS to simulate LPV approches but use RNP APP data (minimums, waypoints...). ABAS LNAV/VNAV may be usable only if your aircraft has a precise VNAV simulation. LNAV should be easier to simulate with prior FPA or V/S calculation. Last but not least : RNP should not be figurated on your aircraft so you have to imagine you have this capability, unless you have EPU (error position) display in your cockpit, and an alert system.

For the Airbus X Extended, consider this support forum from Aerosoft (external website).

Then consider the following level of performance-based navigation certifications to decide for which your simulated ACFT is certified :
PBN/A1 : RNAV 10 (RNP 10)
PBN/B1: RNAV 5 all permitted sensors
PBN/C1: RNAV 2 all permitted sensors
PBN/D1: RNAV 1 all permitted sensors
PBN/O1: Basic RNP 1 all permitted sensors
PBN/O2: Basic RNP 1 GNSS
PBN/T1: RNP AR APCH with RF (special authorization required)
PBN/T2: RNP AR APCH without RF (special authorization required)
