ENAC Tetralogy of Angles
Neuro-SensomotoricPSY1Read which way a small clock runs, then measure the turn from one line to another in that direction. In the ENAC EPL form you type 40 angles in four parts of 10: over a picture, between an arrow and a point, around a cross, and as an object to straighten. In the Air France Cadets form you get a figure and 8 clocks, each printing a value, and you tick every clock that matches the angle.
Overview
Read the clock first, every time. It can change from one item to the next, and a turn the wrong way round is wrong however well you measured it. Then size the angle against a right angle or a straight line, and count the steps left over.
Assessments
Part of the ENAC EPL selection (PSY1) battery as “Angles”.
A fixture, not a rotator: four parts of ten, values on a 10° grid, and two of the four parts bury their marks in a background, found by a red mark. The clock's direction decides which of the two openings is asked for and the sign it is written with: no sign under a clockwise clock, a minus under an inverted one; the other opening is refused, and so is the sweep with the wrong sign. Time is not the main pressure on this one: most candidates finish, with room to go back over the first angles.

A different board from the EPL typed test: one plain figure and eight to ten clocks around it, each carrying a signed value under a face of its own, rotated and sometimes mirrored. Tick every clock whose value, read in that clock's own direction, lands on A; one to four a board, never none. A right clock ticked earns points, a wrong one ticked costs points, and a right one left costs nothing. Thirty boards in 26:00 on one clock, revisable until submitted, with true angles on a 15° grid.
Battery mappings are based on public information and may change.
The clock
- Its digits: only the 12, 3, 6 and 9. The face can be turned, and sometimes the digits run the other way round.
- Its direction: find the 12, then the 3. If the 3 is a quarter turn clockwise from the 12, the clock runs clockwise. If not, it runs anticlockwise.
One angle, four ways to draw it
The ENAC EPL form: forty angles in four parts of ten. Start on the first line and turn the way the clock runs until you reach the second, however far that is. Type the size of that turn, a multiple of 10. If the clock runs anticlockwise, put a minus in front. Only that one value counts. Pick a part, type the angle, then hit Check.
Type the angle in degrees, with a minus in front when the clock runs anticlockwise.
One figure, eight clocks
The Air France Cadets form: each clock prints a value. A positive value turns the way its own clock runs, and a negative one turns the other way. Tick every clock whose value carries O onto A. Between one and four of them are right. A wrong tick costs you a point, but a right clock you leave unticked costs nothing.
Game Phases
Clock First
Find the 12, then the 3. That's the way the clock runs.
Anchor the Size
Start from 90° or 180°, then count the 10s or 15s either side.
The Right Writing
The typed form takes one value. The ticked form can have up to four right clocks.
Use the Time
There's time to spare, so go back and check your first angles once your eye has settled.

Spatial Orientation
11 exercisesSpatial Awareness
Visualise a 3D shape from a fixed viewpoint and pick the matching 2D view. Tests mental rotation and spatial perception under time pressure.
Mental Rotation
See a 3-D block figure, then pick the option that is the same object rotated — not a mirror image or a different shape. The classic Shepard–Metzler / Vandenberg–Kuse task.
Spatial Orientation
Read your compass heading and a beacon's bearing, then judge where the beacon lies relative to your aircraft. Tests spatial orientation and sense of direction under time pressure.
Cube Folding
Mentally fold a flat net of six symboled faces into a cube, then pick which of four folded cubes it makes. Tests spatial visualisation and 2D-to-3D reasoning under time pressure.
Sense of Direction
One arrow shows your vehicle's new heading; you name the driving maneuver that got you there — straight, left, right or U-turn — on a circular four-wedge control. A practice version of scales nav, Aon's (cut-e's) Sense of Direction test: one minute, arrows chaining item to item, your heading held only in memory, plus a sudden-death Challenge mode.
ENAC Point Tracking
Two figures side by side. The round one holds a few circles and four points lettered A to D. The square one is the same figure, turned in the plane and moved, with only one of the four points left and sometimes a circle or two added. You name the point that was kept. The exam format is 32 boards in 6:30 on one clock.
ENAC Objects Tracking
Two pictures, one above the other. In the lower one, an object is circled and five more carry the letters A to E. The upper one holds the same objects moved over together, among plenty of others. Tick the letters still at the same distance and direction from the circled object, and still exactly the same. The exam format is 30 boards in 12 minutes.
ENAC Patrons de Dés
A die with a letter or a rune on each face, two or three views of it, and its net laid flat with the cells numbered. Type under each symbol the number of the cell it goes in. The symbols are already turned the way they lie on the net, so the cell you pick decides how each one sits on the die. The exam format is two parts of 10 boards, 20:00 a part for Air France Cadets and 17:00 for the ENAC EPL.
ENAC 3 Dimension Rotations
A chair starts in a slanted position, then 4 turns follow, one at a time. Each turn is a ball with an arrow and an angle, always a multiple of 45°, and you only see the chair itself beside the first one. Then you picture the chair from a named side, say from the right or from above, and pick it out of 5 pictures. The exam format is 40 boards, 5 seconds a turn and 15 seconds to answer.
ENAC Cube Nets 2D/3D
Two nets of the same die side by side: the original, complete, and yours, unfolded from the die turned another way, with a few faces in place. Drag the other faces onto yours so that it folds back into the same die, and turn the letters the right way round. The exam format is 5 boards, 90 seconds each.
ENAC Viewpoint Finder
A photograph shows a few simple solids standing in the sand. Beside it, the same scene is drawn from directly above, with eight camera positions round it, and every camera looks at the centre. Click the position the photograph was taken from. The shadows, the left-to-right order of the objects, and the objects you can't see all tell you where you're standing. The exam format is 10 boards with 20 seconds each.
