Question

4) Four avionics suites are being considered for a new small airplane (see table below) and you have been tasked with recommending one over the others. Using weight (W), cost (C), voltage (V), IFR rating (R), number of software features (F), screen widtłh (S), and screen resolution area (tw-h) as variables, suggest a cost function that can be used to indicate the most suitable avionics suite. (Hint: use the min or max of each column as a reference value, noting that low weight, cost, and voltage; IFR rating high number of software features; large screen width and resolution are favorable) Software Features 35 82 36 24 Screen Width, in 10 12 10 Resolution w x h 800 x 6000 1024 x 726 800 x 600 480 x 386 IFR Rated Cost $ 8900 12 13,500 12 9100 18 6000 12 Welght Ibr Voltage Amp Type Avionics Suite 1 9.8 Avionics Suite 2 11.2 Avionics Suite 3 10.9 Avionics Suite 4 8.8

Answer 1

Four avionics suites are being considered for a new airplane as shown in the table in the question. The most suitable avionics suites are Avionics Suite 2.

Considering the following highest value of-

Weight – 11.2 (Avionics Suite 2)

Cost $- $ 13,500 (Avionics Suite 2)

Avg Voltage Amp- 18 (Avionics Suite 2)

IFR Rating- 1(Avionics Suite 2)

Software Feature- 82(Avionics Suite 2)

Screen Width- 12 (Avionics Suite 2)

Favourable Resolution- 1024x726 (Avionics Suite 2)

Avionics Suite 2 is having the best combination of voltage amp, IFR rating, screen feature, screen width and the most favourable resolution. Its wright is around 11.2 lb and costs around $ 13,500. At the given weight and cost it is offering 82 software features and most favourable resolution. Hence, Avionics Suite 2 should be considered for a new airplane.
