Aircraft Hydraulic Systems - Fundamentals, Nihad E. Daidzic
Aircraft Hydraulic Systems - Fundamentals, Nihad E. Daidzic
Aviation Department Publications
Aircraft hydraulic systems are essential non-propulsive power systems. Hydraulic power systems are used to power major functional aircraft systems, such as flight controls (primary and secondary), friction braking, nose gear steering, thrust-reversers, operating heavy cargo doors, etc.
Wind Tunnel Measurements And Data Analysis Tutorial, Nihad E. Daidzic
Wind Tunnel Measurements And Data Analysis Tutorial, Nihad E. Daidzic
Aviation Department Publications
This tutorial gives details on processing of raw aerodynamic data measured directly in the wind tunnel on airfoils and wings. Also procedures and equations from the lab report are given and demonstrated how to compute geometric characteristics of wings/airfoils and air data. All numeric results are typically rounded to five significant digits.
Keeping Your Distance: The Science Of Turns-Around-A-Point And Ground Reference Maneuvers, Nihad E. Daidzic
Keeping Your Distance: The Science Of Turns-Around-A-Point And Ground Reference Maneuvers, Nihad E. Daidzic
Aviation Department Publications
Ground reference maneuvers are more important than you may think. Frequently regarded as unimportant or boring, ground reference maneuver training is often limited to a few minutes of flight instructor demonstration and brief student practice.

United States Patent, Patent Number US 10,202,204 B1, Date of Patent February 12, 2019.
A total runway safety system (TRSS) and method measures, monitors, manages, and informs flight crew on the progress of takeoffs and landings and of any hazardous runway conditions. In some embodiments, the TRSS measures, monitors, and informs flight crew of longitudinal and lateral runway tracks thus preventing overruns and veer-offs during takeoffs and landings. In some embodiments, backscatter of infrared laser beams emitted by the aircraft is used to evaluate groundspeed and the reflectivity of the runway surface to make estimates of the surface conditions, roughness …

Weight and Balance (W&B) computations are essential step in ensuring that the aircraft (in this case FAR/CS 25 Transport-category airplanes) is properly loaded with its Center of Mass (CM) of Center of Weight/Gravity (CG) in the proper range.
A New Model For Lifting Condensation Levels Estimation, Nihad E. Daidzic
A New Model For Lifting Condensation Levels Estimation, Nihad E. Daidzic
Aviation Department Publications
Knowledge of and the ability to predict lifting condensation levels (LCL) is important ingredient in weather predictions, cloud formation, planetary albedo and Earth’s energy balance. It is also essential topic in aviation safety and flight operations. In this article, we derive a new model of LCL and compare it to some older commonly-used models. This includes also the recently published Romps’ (2017) model. The new model presented here includes dependence, however weak, of the surface atmospheric pressure and the specific humidity on the LCL height and temperature. Such is not the case with widely used models and expressions by Espy …
