Some airplane model information is missing?
You may find that some aircraft's model informations are missing.
Our aircraft's model database comes from the FAA database. They store aircraft id, model, manufacturer, engine type, number of engines etc...
Squowk uses this information to sort times by engine type or number of engines. Some aircraft's model may be missing those information.
If you create an aircraft with those informations missing, the administrators will be automatically notified in order to correct to problem.
Meanwhile if the problem is not yet fixed, you will find that Squowk treats aircrafts without informations as single-engine piston. If your total time or other times are wrong the problem might come from there.
