The speed is too low for an indication.

An adymensional number relating the lift with the dynamic pressure of the incoming flow. It is dependent on the form of the object and the angle of attack.

Vmu is the minimum unstick speed.

It is the calibrated airspeed at and above which the airplane can safely lift off the ground and continue the takeoff. Lift-off is not possible prior to reaching this speed.

Vmu is not an operational speed and is established in flight testing only.

The Center of pressure position is dependent of the angle of attack. As the angle of attack increases the center of pressure moves closer to the leading edge.

The airspeed indicator uses part of the aircraft's pitot-static system to measure and compare the dynamic air pressure between air moving into the pitot tube and static air pressure measured in the case. 

The ASI is calibrated to ISA at MSL and represents the dynamic pressure as indicated airspeed in knots per hour.

ASI errors can originate and vary from:

Instrument Pressure Density Compressibility Maneuver Blocked pitot static system

Swept wings have:

• Poor lift qualities

• Higher stall speeds

• Speed instability at low speeds

• A wing-tip stalling tendency

VHF Omnidirectional Radio Range (VOR) is defined as VHF Omnidirectional Radio Range, an aircraft navigation system operating in the VHF band.

VOR's are assigned radio channels between 108.0 MHz and 117.95 MHz (with 50 kHz spacing); this is in the very high frequency (VHF) range.

This provides pitch manoeuvrability.

Crew Resource Management (CRM) is the effective use of all available resources for flight crew personnel to assure a safe and efficient operation, reducing error, avoiding stress and increasing efficiency.
