Basic type information example

The Basic Information window allows you to enter information for the aircraft type:

Type information
Type Name e.g. C182T or P2002
ICAO Type Identifier e.g. PA44 or EC30. Required when submitting a plan to NAIPS/IFIS. The ICAO type identifier for your aircraft can be found at: NOTE: If your aircraft has no ICAO type code, enter ZZZZ
Description e.g. Cessna 182T or Tecnam Sierra
Performance category Select whichever reflects the normal speed in approach configuration (Note: this is NOT cruise speed)
Wake turbulence category Select most appropriate from a list of MTOW levels.
Pilots Operating Handbook .PDF URL e.g. This will make that document available for easy download and viewing in the POH option within the Text tab
Is this aircraft a helicopter? If the aircraft is specified as a helicopter, then the Nearest Items view will display nearby helicopter landing sites. If this setting is set to NO, then HLSs are hidden.
Aircraft icon Select from the various icon options. This icon will be displayed on the map when this particular aircraft type is selected in an open flight plan. To change the icon displayed when no flight plan is open, you’ll need to change the Default Icon in User Settings.
Weight Units The weight units used for passengers, baggage or cargo to be loaded in the aircraft (kg or lbs)
Fuel Units The units used by the fuel calculations – both in filling the fuel tanks and the fuel burn calculations (Litres, US Gallons or lbs
Fuel Type Select between AVGAS, AVTUR, MOGAS or OTHER
Fuel Specific Gravity Used by AvPlan to calculate the weight of the fuel load. This will be entered automatically when a Fuel Type is selected. Only adjust this if you know why you need to
Fuel Cost Will allow flight costings in the flight plan or stage summary
Arm Units Used in the weight and balance setup, select between mm or inches
MTOW Maximum Takeoff Weight (aka Max Gross Weight. Required for ALL aircraft)
MLW Maximum Landing Weight. If not specified in the POH, set equal to MTOW
MZFW Maximum Zero Fuel Weight. If not specified in the POH, can be left blank
Max Ramp Maximum Ramp Weight. If not specified in the POH, set equal to MTOW
Basic Performance
Cruise TAS Planned cruise true airspeed in knots
Climbing IAS Cruise climb indicated airspeed
Climb fuel flow Aircraft’s fuel flow during an enroute climb
Cruise fuel flow Aircraft’s basic fuel flow at cruise
Holding fuel flow Aircraft’s fuel flow when at endurance power settings
Final Fuel (Fixed reserve) fuel flow Fuel flow for the Final Fuel (fixed reserve) fuel component
Rate of climb Average rate of climb for an enroute climb in feet per minute
Rate of descent Cruise descent average rate in feet per minute
Total fuel Total fuel capacity of the aircraft
Service ceiling Important for app performance during wind/altitude calculations, the app won’t calculate winds above the service ceiling
Glide Ratio The :1 is assumed. e.g. if the glide ratio is 10:1, enter the figure 10. If it’s 12.7:1, enter 12.7. Used in the Pro feature Glide Planning. Note that the glide ratio is not scaled- i.e. it is in ft/ft, m/m. If you are unsure of what your aircraft’s glide ratio might be, Wikipedia is illuminating.
Glide IAS The best glide indicated airspeed, used in the Plus/Premium feature Glide Planning. Assume the worst-case scenario: i.e. at MTOW. Did you know that best glide speed is typically equal or very close to the average of Vx and Vy? If best glide speed is not given in your POH, you can use this simple method to estimate it.
Minimum Runway Length Used in the Pro feature Glide Planning, where appropriate airfields are pointed out on the map in flight. Any with runways below this length will not be displayed
Plan Using High Level Routes Switching this on forces AvPlan’s IFR auto-route function to select high air routes over low ones – good for turbine aircraft
Other Details
Aircraft password Optional; adds a password to the file so that you cannot edit it without knowing the password. This is NOT a secure protection of the aircraft file, but may help prevent accidental editing
Aircraft Model version Optional: You can give your aircraft file a version name, then copy it and make another version if you wish.
Advanced Performance (for Plus/Premium subscribers)
Optional Critical Point paramaters Specifying values here will allow AvPlan to calculate up to two additional Critical Points along the route. In addition to the default CP corresponding to normal cruise TAS in both directions, you can have two optional CPs at reduced TAS values corresponding, for example, to single engine flight in a multi engined aircraft, or depressurised flight at lower than optimum altitudes. The default CP is labelled simply ‘CP’ when displayed on the en-route chart and in the Flight Plan Table. The two optional CPs can be given short custom names such as, for example, ‘OEI’ or ‘DEPR’. The custom names will display on the enroute chart and Flight Plan Table if optionally enabled
CP1 name Optional. A name for the first of two optional additional Critical Points. e.g. OEI for One Engine Inoperative
Reduced TAS 1 Optional. TAS value corresponding to e.g. OEI, used for Calculations related to CP1
Reduced fuel flow for CP1 Optional. Allows AvPlan to calculate the fuel burn at the the reduced TAS values specified for e.g. OEI
CP1 Altitude Optional. Altitude normally flown when in the e.g. OEI condition. If specified, will be used to determine the winds at the OEI level for more accurate CP1 calculation
CP2 name etc Optional. Data for a second degraded performance condition- (typically depressurised), as described above
For some Enterprise customers only
IU Formula Optional. A Formula that describes the relationship between Moments and Index units
%Mac Formula Optional. A Formula that describes the relationship between Moments and the CofG in terms of Mean Aerodynamic Chord
