ASCI 310: Aircraft Performance Research Project

Objectives

One of the requirements for this course is an Aircraft Performance Research Project that entails planning a flight from Denver International Airport (KDEN) to Chicago O'Hare International Airport (KORD) for a given aircraft, weather conditions, and assumptions. The objective is to apply what has been learned throughout this course. Drawing on aeronautics theory and using the performance charts and equations presented in the course, each student is to answer a sequence of questions that step through the planning process. Remember, as with all of the exercises, all work (calculations) must be shown as much as possible. After all of the questions have been answered, the next task

Assume Flaps at 15 deg.

(1.5 pts) Find Maximum Takeoff Weight for the given conditions. Assume takeoff is at Max Recommended Takeoff weight accounting for Density altitude (see Figure 11-21).

Pressure altitude = 5430 – (29.32 – 29.92) * (1000 / 1) = 6030 feet

According to fig 11.21, the Max Recommended Takeoff weight is 82500lbs.

(1.5 pts) Find Takeoff Speeds: V1, V2, VR (see Figure 11-25). Assume Min Speed due to VMCG Requirements is OK.

Using Figure 11-25,
V1 = [(85 – 82.5) / (106 – V1)]
= 104 KIAS
V1 = 104 + 6 – 0.5 + 2
= 111.5 KIAS (Corrected)

V2 = [(85 – 82.5) / (127 – V2)]
= 125 KIAS
V2 = 125 - 1
= 126 KIAS (Corrected)

VR = [(85 – 82.5) / (118 – V1)]
= 116 KIAS
VR =116 + 2
= 118 KIAS (Corrected)

(1.5 pts) Find Flap Retraction Speed (KIAS).

Flap Retraction Speed = V2 + 10 knots
= 126 + 10
= 136 KIAS

(1.5 pts) Find Slat Retraction Speed (KIAS).

Slat Retraction Speed = Flap Retraction Speed + 25 kts
= 136 + 25
= 161 KIAS

(1.5 pts) Find Critical Field Length (ft).

Using Figure 11-22, Critical Field Length = 4500 fts

(1.5 pts) Find Distance to Accelerate and Stop with a Single Engine Failure at V1 (ft).

Using Figure 11-23,
Distance to Accelerate and Stop with a Single
