Abstract:	Sixteen pilots of two widely different experience levels were flight tested in a Beechcraft Twin Bonanza on an area navigation task involving 3-D approaches having two levels of navigation procedural complexity. Two types of displays were used for level-ff at MDA, command leveloff and an altimeter. The four recorded performance measures were vertical steering, horizontal steering, airspeed control, and procedural accuracy. The less complex approach procedures (Simplified) resulted in better performance on all four recorded measures than the more complex procedures (Standard), However, no reliable performance differences were evident between levels of pilot experience and types of leveloff displays. In comparison with previously assumed values of flight technical error, Standard Procedures generally yielded larger errors, and Simplified Procedures generally smaller errors.
