If you previously entered your password details into Command Flight Planner with capitalisation different from the capitalisation stored on our records then login will fail.   Re-enter your password in the Command Flight Planner with special regard to capitalisation.

If you can successfully log in to our web site using a user name and password, then that user name and password is what you should use in the Command Flight Planner.   If you no longer remember your password then you can use the web site Forgotten Password facility to gain access to set a new password.

The submit button on the NAIPS flight plan submission window will be greyed out if any essential information is not filled in.

All fields on the NAIPS submission window which have a pale blue background must be filled in for ALL flight stages.  The most common missing item is the departure time.

A common cause of NAIPS connection problems is your Internet Explorer web browser settings. Command Flight Planner uses components of Internet Explorer to communicate with NAIPS over the Internet (This is true even if you use Firefox, Opera, or another browser yourself).

Run Internet Explorer and check the following:

1. Select ‘Tools’ -> ‘Internet Options’.
2. Click on the ‘Settings’ button in the middle right hand side of the window under ‘Temporary Internet Files’. Ensure that any option other
than ‘Never’ is selected, then click ‘Ok’.  The default value is ‘Automatically’ and that should be adequate.
3. Click the ‘Delete Files’ button next to the ‘Settings’ button. Tick the box that says ‘Delete all offline content’ and click ‘Ok’.   If that option is
not visible then you should delete “Temporary Internet Files” and “Cookies”.  This may take a minute or so to complete if you have a lot of
browsing material accumulated on your system.  More information on these processes can be found on Microsoft support pages:

In 2019 NAIPS upgraded their internet security by dropping support for TLS 1.0. The unexpected result, from NAIPS perspective, was that older windows computers would no longer be able to communicate with NAIPS. If you are using a legacy computer running Windows XP, you can select the NAIPS proxy setting in the NAIPS settings screen to overcome the restriction. CFP will use a proxy service to upgrade the secure protocols to ones that are acceptable to NAIPS.

Endurance time is the longest time the aircraft could be expected to stay airborne under planned conditions, assuming any alternate is used, all reserves are burnt, and including the extra cruise time any remaining fuel would give you.
To compute the endurance time Command Flight Planner estimates the amount of time and fuel required, at relevant consumption rates, for each of these stages of flight:

– Climb, cruise, and descent
– Fuel required for planned holds or delays
– Any fuel required to reach a specified alternate airfield from the primary destination
– Fuel required for variable reserve
– Fuel required for fixed reserve time
– Fuel required for taxi

The total of all the fuel quantities above is subtracted from the total fuel on board to give a fuel margin.  The fuel margin is converted to a potential flight time at the cruise rate.

The airborne endurance time is computed by adding all the time periods computed above excluding taxi (which is spent on the ground) and the additional time that the fuel margin supplies.  At the end of this time airborne one would expect complete fuel exhaustion.
The process above is performed for each stage of the flight plan.  The figures can be seen on the Fuel Management panel and some of the printed output of the Command Flight Planner.

If you are regularly flying at altitudes at or below 10,000 feet, then there is no need to load the high-level wind data. You can save a little bit of time when requesting briefs by only loading the low-level winds. If a high-level winds update is available Command Flight Planner will automatically download the data before requesting the NAIPS brief. As the files are quite large, on slow internet connections, it can take some time for the download to complete.

The amount of textual information returned in an SPFIB briefing can depend on the options selected in the SPFIB briefing request screen. Briefing involving multiple areas can result in the consumption of many pages when printed. To minimise the size of the returned briefing, review the options selected in the SPFIB request screen prior to actioning.
