Hello.
I’ve just purchased a 2008 J160 here in the UK. Been checking ailerons rudder and finally the flap deflection and generally getting to know the plane.
I understand that the flaps are originally checked with a wood template which isn’t with the aircraft. Can anyone give me a full flap down degree angle? Have put an inclinometer on the flaps and have a reading of 62 60 angle this seems a rather steep flap angle or is it correct. Any advice welcome.
Jeff.
Hello Jeff,
Yes 60 degrees does seem excessive. The flap angle is with reference to the lower surface of the wing. Not sure which exact J160 version you have but the J160-C has a full flap deflection of 39.5 degrees. There is a tolerance on this of +/- 1 deg. All J160 versions will be very close to this.
Hello. Many thanks for your reply regarding the flap angle. Now have to find out how to adjust and reduce the deflection. One question has the flap motor any micro switches to set the amount of travel or is this set elsewhere on the flap mechanise?
It is set elsewhere in the flap mechanism. 60 deg is a lot more than 45 so it might be worth checking that all the correct length pushrods have been used, that it is a jabiru flap motor (right stroke), etc. If so the geometry of the mechanism is important. If the arms aren't setup at the right angles in relation to the each other and wing the angle can be wrong. The jabiru construction manual can be found on the jabiru website. under support. That would be a good place to start.
