What range does the transonic airflow mach regime take place at?
Mach numbers from 0.75 to 1.20.
PHAK ch. 5
What does ‘critical mach number’ refer to?
The speed of an aircraft in which airflow over any part of the aircraft or structure under consideration first reaches Mach 1.0 (The speed of an aircraft in which airflow over any part of the aircraft or structure under consideration first reaches (but does not exceed) Mach 1.0 is termed “critical Mach number” or “Mach Crit.”)
PHAK ch. 5
Stall speed is affected by
weight, load factor, and power.
A propeller rotating clockwise as seen from the rear, creates a spiraling slipstream. The spiraling slipstream, along with torque effect, tends to rotate the airplane to the…
left around the vertical axis, and to the right around the longitudinal axis.
explain: The prop forces the air to spiral rearward, creating a rolling moment to the right around the longitudinal axis. Torque reaction tends to roll the aircraft left about its vertical axis, opposite of the prop direction.
What is maximum ramp weight?
Maximum zero fuel weight + usable fuel
more: Maximum ramp weight is the total weight of a loaded aircraft including all fuel. It is greater than the takeoff weight due to the fuel that will be burned during the taxi and run-up operations. Ramp weight may also be referred to as taxi weight.
you are transitioning from an area of cold, dry air to an area that is warm and moist. Assuming your airspeed is constant, what happens to lift and drag?
Both lift and drag will decrease.
explain: Warm air is less dense than cool air, and moist air is less dense than dry air. This means lift and drag will be decreased, as they are both directional proportional to air density.
As a commercial pilot, you plan to give airplane rides at a charitable event. What action must you first take?
Notify the local FSDO with a signed letter
ex: At least seven days before the event, each sponsor of an event described in this section must furnish to the responsible Flight Standards office for the area where the event is scheduled a signed letter with event details and a photocopy of the pilot certificate, medical certificate and proof of currency in the logbook.
To act as pilot in command of an airplane towing a glider, the tow pilot is required to have
a logbook endorsement from an authorized glider instructor certifying receipt of ground and flight training in gliders, and be proficient with techniques and procedures for safe towing of gliders.
FAR 61.69
During flight a fire, which was extinguished, burned the insulation from a transceiver wire. What action is required by regulations?
An immediate notification by the operator of the aircraft to the nearest NTSB field office.
In what type of operation, not regulated by 14 CFR part 119, may a commercial pilot act as pilot in command and receive compensation for services?
Crop dusting, spraying, and bird chasing.
A pilot convicted for the violation of any Federal or State statute relating to the process, manufacture, transportation, distribution, or sale of narcotic drugs is grounds for
suspension or revocation of any certificate, rating, or authorization issued under 14 CFR part 61.
Which is required to operate an aircraft towing an advertising banner?
A certificate of waiver issued by the Administrator.
FAR 91.311
Can you formation fly with pax for hire?
No
FAR 91.111
What flight time must be documented and recorded by a pilot exercising the privileges of a commercial certificate?
Flight time showing training and aeronautical experience to meet requirements for a certificate, rating or flight review.
ex: Each person must document and record training and aeronautical experience used to meet the requirements for a certificate, rating, or flight review or to meet recent experience requirements.
FAR 61.51
The carriage of passengers for hire by a commercial pilot is
not authorized in a ‘limited’ category aircraft.
No person may operate a limited category civil aircraft carrying persons or property for compensation or hire.
FAR 91.315
