DA-20 C1 Limits & Airspeeds

Question 1

Vso (power off stall speed landing config)
*Vs (power off stall speed clean config)
Vr
Vx (TO)
Vx (Clean)
Vy (TO)
Vy (Clean)
Vfe (TO)
Vfe (LDG)
*Va (max a/s plane is not overstressed with full deflection control surfaces)
Vno
Vne
V best glide
Max Crosswind Component

*Indicated airspeed @ max gross weight (1764 lb)

White Arc
Green Arc
Yellow Arc
Red Line

Answer 1

*Vs0…35 kias
*Vs1…43 kias
Vr…44 kias
Vx (TO)…57
Vx (Clean)…60 kias
Vy (TO)…68 kias
Vy (Clean)…75 kias
Vfe (TO)…100 kias
Vfe (LDG)…78 kias
*Va…106 kias
Vno…118 kias
Vne…164 kias
V best glide…73 kias
Max Crosswind Component…15 kias (POH says 20 kias)

*Indicated airspeed @ max gross weight (1764 lb)

Vs0 < White Arc < Vfe…this is landing flap operating range (34-78 kias)
Vs1 < Green Arc < Vno…normal operating range (42-118 kias)
Yellow Arc…caution range, only enter in smooth air and w/caution (118-164)
Vne = Red Line…never exceed this speed, possible structural damage or failure

Question 2

Max ramp weight
Max takeoff weight
Max landing weight
Max weight baggage area

Cruise load factor
TO or LDG Flap load factor

Answer 2

Max ramp weight…1770 lb
Max takeoff weight…1764 lb
Max landing weight…1764 lb
Max weight baggage area…44 lb

Cruise load factor: -2.2g - 4.4g
TO or LDG Flap load factor: 0 - 2g

Question 3

Total fuel quantity
Usable fuel
Unusable fuel

Answer 3

Total fuel quantity…24.5 gal
Usable fuel…24 gal
Unusable fuel…1/2 gal

Question 4

Cruse settings (KIAS, RPM, GPH)

Economy
Normal
Max

Answer 4

Economy…113 kias…2500 RPM…5.9 GPH
Normal…122 kias…2700 RPM…6.5 GPH
Max…126 kias…2800 RPM…7.3 GPH
