1F W Supported by OpenTTD 1.2 (r23504)1.2 Not supported by TTDPatch Aircraft range in tiles. Distance is euclidean, a value of 0 means range is unlimited
  1. Supported by OpenTTD <1.3.1<1.3.1 In OpenTTD before r25115 the units for acceleration were messed up. The unit used was about 1 mph/tick, so aircraft accelerated more than twice as fast. Also values bigger than 19 failed.

Descriptions

Primary (0F) and secondary (11) cargo capacity

Aircraft can transport up to two cargo types. The first (primary) cargo type can be changed when refitting the aircraft.

The secondary cargo type is always mail, and is only present when the primary cargo type is part of the passenger cargo class.

See also the page about vehicle refitting.

Sound effect (12)

The following sound effects are used by planes (note, the setting is ignored for helicopters):

Number Sound
06 Propeller sound 1
07 Jet sound 1
3B Supersonic
3D Jet sound 2
45 Propeller sound 2
46 Jet sound 3

Supported by OpenTTD 1.6 (r27507)1.6 Not supported by TTDPatch Since OpenTTD r27507 also custom sound effects from Action11 are allowed here.

Callbacks (14)

For planes, the following callbacks have to be enabled by setting the corresponding bit in property 14 (certain other, not as frequently used callbacks are available without setting a bit here)::

Bit Value Variable 0C value Callback
2 4 12 Load amount
3 8 15 Set refitted capacity
5 20 19 show a suffix after the cargo type name
6 40 2D Select color mapping for vehicle
7 80 33 Sound effect callbacks

Bit is the bit you have to set, you do this by adding all the values for all the bits. Variable 0C value is what variable 0C will be set to, for checking it in the VarAction2 for callbacks.

Refit cost (15)

Refit cost, using 1/32 of the default refit cost base. This property can be overridden by callback 15E.

Supported by OpenTTD 1.2 (r23087)1.2 Not supported by TTDPatch If the refit cost factor is set to zero and bit 4 of the miscellaneous flags (17) is set, auto-refitting is allowed.

Miscellaneous flags (17)

This is a bit mask, with the following bits:

Bit Value Meaning
0 1 reserved, do not use
1 2 Uses two company colors
2 4 reserved, do not use
3 8 reserved, do not use
4 10 Supported by OpenTTD 1.2 (r23087)1.2 Not supported by TTDPatch Auto-refitting is enabled for refits where callback 15E allows it or prop 15 specifies zero cost.
5 20 Supported by OpenTTD 1.2 (r23861)1.2 Not supported by TTDPatch Use cargo multiplier for default cargo. See page about vehicle refitting.
6 40 Supported by OpenTTD 1.3 (r24124)1.3 Not supported by TTDPatch Disable breakdown smoke effect.
7 80 Supported by OpenTTD 1.7 (r27668)1.7 Not supported by TTDPatch Compose vehicle from multiple sprites.

Note: This also applies to the rotor sprite, if custom rotor sprites are used.

Long format introduction date (1A)

Set the vehicle introduction date, in days since the year 0. This takes account of leap years; dividable by 4, but not 100 unless 400. A start date of 1920-01-01 is obtained with a value of 701265 (51 B3 0A 00). This property must be set after property 00 to take effect.

Not supported by OpenTTD Supported by TTDPatch In TTDPatch, dates after 2044 will be limited to 2044.

Sort vehicle list (1B)

See sort vehicle list for trains for details.

Custom cargo ageing period (1C)

See custom cargo ageing period for trains for details.
