Chp3 Levelling The Aircraft Using A Clinometer Flashcards
What is the rigging position of an aircraft?
An aircraft is in the rigging position when two imaginary references or datum lines, passing at right angles to each other through fixed points in the fuselage, are horizontal.
What do the datum lines in the rigging position represent?
One datum line runs fore and aft in the aircraft, and the other runs in a transverse direction, coinciding with the longitudinal and lateral axes.
How does the rigging position relate to level flight?
The rigging position is equivalent to the normal flying attitude of the aircraft since the longitudinal and lateral axes are horizontal in level flight.
What is the process of placing an aircraft in the rigging position commonly referred to as?
Levelling the aircraft.
What does the term ‘Datum Neutral’ refer to?
Datum Neutral describes the aircraft in a levelled (neutral) position.
What is the most common way of levelling an aircraft when jacked up?
Through fuselage reference or datum points and a clinometer.
What do datum points provide?
A mounting for the level checking equipment (clinometer).
How many pairs of datum points are there for setting the aircraft level?
Two pairs; one for longitudinal level and one for lateral level.
What must always be consulted for levelling methods?
The relevant aircraft maintenance manual.
What is the purpose of adjusting relevant jacks?
To achieve the required aircraft attitude.
What is the exercise for trainees regarding Aircraft Jack & Levelling?
To carry out an Aircraft Jack & Levelling using a Clinometer on a Gazelle Exercise 11 (Supervised by Instructor).
