737 Max Recertification Process

As we all know the Recertification flight test for 737 max completed on 1-July-20. This is 737-7 Aircraft. As per the FAA below are the list of process further required to ungrounding of the Aircraft. But this is applicable only to US, each country's regulator has to approve it to make sure Max is flying safe only then it is allowed in their Airspace. The remaining tasks include: JOEB Validation & FSB Review  – The FAA’s Flight Standardization Board (FSB) and the Joint Operations Evaluation Board (JOEB) which includes international partners from Canada, Europe, and Brazil will evaluate minimum pilot training requirements.  The FSB will issue a draft report for public comment addressing the findings of the FSB and JOEB. Final FSB Report  – The FAA will publish a final FSB report after reviewing and addressing public comments. Final Design Documentation and TAB Report  – The FAA will review Boeing’s final design documentation in order to evaluate compliance with al...

Weather Radar

What is Airborne Weather Radar ? Is it required ? Airborne weather radar is a type of radar used to provide an indication to pilots of the intensity of convective weather. Modern weather radars are mostly doppler radars, capable of detecting the motion of rain droplets in addition to intensity of the precipitation. Typically, the radar antenna is located in the nose of the aircraft. Signals from the antenna are processed by a computer and presented on a screen which may be viewed by the pilots. Droplet size is a good indicator of strong updrafts within cumulonimbus clouds, and associated turbulence, and is indicated on the screen by patterns, color coded for intensity. Some airborne weather radar systems may also be able to predict the presence of wind shear. Weather Radar   Is it required to be installed in Aircraft?   As per FAA and aviation regulators worldwide, all operators shall not operate unless it is equipped with airborne weather r...

Aircraft Nose Cone

Why the Nose Cone in Aircraft is Important ?   Nose cone is also known as RADOME. As the Name Implies, it is the DOME which consists of Radar Equipment. The function of the radome is to protect the antennas installed in the nose of the aircraft from airflow, rain, hail, lightning strike, bird strike,etc. At the same time it must provide a radio-frequency transparent window, suitable for the microwave signals of the weather detection radar, instrument landing system and microwave landing system. The most demanding system in terms of radome radio frequency specification is the weather radar.   Nose Cone/Radome Sources of radome degradation   There are many reasons for the performance level of a radome to degrade below minimum requirements. They range from lightning strike, bird strike, natural erosion, water ingress for some types of radomes, ageing, poor, repairs such as wrong material used, or over-painting.   How a degraded radome affects t...

Swept Wings

A swept wing is a wing that angles either backward or occasionally forward from its root rather than in a straight sideways direction. Forward Swept Wings Backward Swept Wings Why Do Airplanes Have Swept Wings? If you look at commercial airplanes as well as many privately owned airplanes you’ll probably notice that most have swept wings. In other words, their wings don’t extend straight out from the sides. Instead, they angle backwards to form a V shape. Faster an airplane is intended to fly, the greater the angle of its wing sweep. Swept Wings Are Longer Than Straight Wings Using swept wings increases the total length of an airplane’s wings. If one airplane has swept wings, whereas a second airplane of the same type has straight wings, the former will have longer wings.  Swept wings are essentially longer than straight wings because they are angled backwards. And with longer wings, airplanes using swept wings perform differently than their straight-winged counterpart duri...
